History of the NTCIP Development

NEMA initiated the development of the NTCIP in 1992. In early 1993, the US Federal Highway Administration (FHWA) brought together transportation industry representatives to discuss obstacles to installing field equipment for new Intelligent Transportation Systems (ITS). The representatives said that the number one priority was the need for an industry-wide standard data communications protocol. Since the NEMA Transportation Section members had already started work on a new industry standard, they offered to expedite and expand the scope of their activities.text.

The key objectives of the new NTCIP protocol were the interchangeability of similar roadside devices, and the interoperability of different types of devices on the same communications channel. fetal doppler

In 1996, the FHWA suggested a partnership of standards developing organizations to expand both user and industry involvement. AASHTO and ITE signed an agreement with NEMA to establish the Joint Committee on the NTCIP, and to work together on developing and maintaining the NTCIP standards. heartbeat monitor

NTCIP Benefits test glucose meter

NTCIP standards offer increased flexibility and choices for agencies operating transportation management systems. NTCIP standards usage removes barriers to interagency coordination and allows equipment of different types and different manufacturers to be mixed on the same communications line. For these reasons, operating agencies benefit from specifying that NTCIP be included in all future acquisitions and upgrades, even if NTCIP is not initially used.

According to the NTCIP Guide, use and application of the NTCIP provides the following benefits to Intelligent Transportation System (ITS) deployers:

Avoiding Early Obsolescence While retrofitting legacy equipment and systems with NTCIP support is not practical in most situations, most manufacturers offer NTCIP support in their ITS devices. It is possible to migrate a system gradually, since it is possible to operate a mixture of NTCIP and non-NTCIP devices in the same system, though not on the same communications line. Equipment may also continue to use a current protocol even though the device may also support NTCIP as a second protocol. Integrating legacy equipment and systems with NTCIP-conformant upgrades in this manner ensures that an operating agency systems and equipment remain useful and compatible long into the future.

Providing a Choice of Vendor Since a computer system that supports NTCIP can communicate with any device from other vendors that are NTCIP-conformant, the number of vendors and systems, field devices, or software that can be considered for procurement increases greatly. While vendor-specific features may only be available to other software and ITS devices from the same vendor, the basic functionality described in an NTCIP standard is available regardless of vendor. This requires that agency specifications (procurement documents) adequately specify the mandatory and optional conformance requirements that support the agency functional requirements. However, NTCIP makes it easier for an agency to gradually change its software, controllers and other field devices from one vendor to supporting multiple vendors for the entire system.

Phased Procurement and Deployment Specifying NTCIP allows agencies to procure devices and center systems in phases, over several financial cycles. For example, many agencies procure a few signs one year, then a few more the next year, and so on. Sometimes devices are procured from one vendor, and sometimes from multiple vendors. Specifying NTCIP standards means that multiple deployment phases, over multiple years, can be integrated, with little difficulty. The initial deployment establishes an ITS communications infrastructure that can be leveraged by future deployment phases resulting in improved cost/benefit for ITS projects.

Enabling Interagency Coordination NTCIP allows agencies to exchange information and (with authorization) basic commands that enable any agency to monitor conditions in other agencies systems, and to implement coordinated responses to incidents and other changes in field conditions when needed. Such data exchange and coordinated response can be implemented either manually or automatically. One agency can monitor, and issue basic commands, if authorized, to field devices operated by another agency, even though those devices may be from a different vendor than those used by the monitoring agency. Potential applications of interagency coordination include:

(a) Coordinating timed transfers at a shared transit center,

(b) Coordinating traffic signals across jurisdictional boundaries,

(c) Providing traffic signal priority for selected, e.g., behind schedule, transit vehicles,

(d) Providing real-time information to a shared traveler information center,

(e) Monitoring traffic volumes on another agency roadway,

(f) Coordinating the operation of a freeway ramp meter with an adjacent traffic signal, or

(g) Posting a warning message on another agency dynamic message sign.

Use One Communications Network for All Purposes NTCIP allows a management system to communicate with a mixture of device types on the same communications channel. For example, with the addition of appropriate application software in the system computer, a dynamic message sign could be installed near a signalized intersection, and the computer could communicate with the sign controller using the communications line or channel already in place for the traffic signal controller, if certain aspects of the communications protocols, that is, the Data Link and Physical layer protocols are the same. Similarly, a wide area network interface installed for communications with a system operated by another agency can be used for communications with any number of other systems, of any type, if NTCIP and the C2C Data Dictionaries and Message Sets of other efforts, such as the Traffic Management Data Dictionary (TMDD), are used. The communications network is usually one of the components of a transportation management system that requires the most resource investment. NTCIP ensures flexibility in the future use of that component.

NTCIP Communications Standards

Center to Field Device Communications

NTCIP has enabled the center to field communication and command/control of equipment from different manufacturers to be specified, procured, deployed, and tested. NTCIP communications standards for field devices are listed below: (the corresponding NTCIP document number is shown in parentheses):

Traffic signals (NTCIP 1202)

Dynamic message signs (NTCIP 1203)

Environmental sensor stations (NTCIP 1204)

Closed circuit television cameras (NTCIP 1205)

Vehicle count stations (NTCIP 1206)

Freeway ramp meters (NTCIP 1207)

Video switches (NTCIP 1208)

Transportation sensor systems (NTCIP 1209)

Field master stations for traffic signals (NTCIP 1210)

Transit priority at traffic signals (NTCIP 1211)

Street lights (NTCIP 1213)

Center to Center Communications

Center to center (C2C) communication involves peer-to-peer communications between computers involved in information exchange in real-time transportation management in a many-to-many network. This type of communication is similar to the Internet, in that any center can request information from, or provide information to, any number of other centers.

An example of center to center communications is two traffic management centers that exchange real-time information about the inventory and status of traffic control devices. This allows each center system to know what timing plan, for example, the other center system is running to allow traffic signal coordination across center geographic boundaries. Other examples of this type of communication include:

Two or more traffic signal systems exchanging information (including second-by-second status changes) to achieve coordinated operation of traffic signals managed by the different systems and to enable personnel at one center to monitor the status of signals operated from another center;

A transit system reporting schedule adherence exceptions to a transit customer information system and to a regional traveler information system, while also asking a traffic signal management system to instruct its signals to give priority to a behind-schedule transit vehicle;

An emergency management system reporting an incident to a freeway management system, to a traffic signal management system, to two transit management systems and to a traveler information system;

A freeway management system informing an emergency management system of a warning message just posted on a dynamic message sign on the freeway in response to its notification of an incident; and

A weather monitoring system (environmental sensors) informing a freeway management system of ice forming on the roadway so that the freeway management system is able to post warning messages on dynamic message signs as appropriate.

NTCIP communications standards for center to center communications are listed below: (the corresponding NTCIP document number is shown in parentheses):

Data Exchange - DATEX-ASN (NTCIP 2304)

Web Services - XML (NTCIP 2306)

The NTCIP has coordinated with other information level standards development organizations during development of the center-to-center application profiles and supports the: ITE Traffic Management Data Dictionary (ITE TMDD), IEEE 1512 Incident Management (IEEE 1512), APTA Transit Communications Interface Profiles (APTA TCIP), and SAE J2354 Advanced Traveler Information Systems standards.

NTCIP Standards Framework

The NTCIP Framework is based primarily on the open standards of the Internet Engineering Task Force (IETF), World Wide Web Consortium (W3C), and ISO, plus NTCIP data dictionary standards specific for the task of ITS device communications. A layered, or modular, approach to communications standards, is used to represent data communications between two computers or other electronic devices.

NTCIP refers to evels in NTCIP, rather than ayers to distinguish the hierarchical architecture applied from those defined by the Open System Interconnection Reference Model (OSI Model) of ISO and the Internet Engineering Task Force (IETF). The five NTCIP levels are: information level, application level, transport level, subnetwork level, and plant level.

The figure below (used with permission) shows how the NTCIP Information, Application, Transport, Subnetwork, and Plant Levels.

NTCIP Framework.

To ensure a working system, deployers should select and specify at least one NTCIP protocol or profile at each level. A discussion of each level, and NTCIP standards that apply at that level, follows:

NTCIP Information Level Information standards define the meaning of data and messages and generally deal with ITS information (rather than information about the communications network). This is similar to defining a dictionary and phrase list within a language. These standards are above the traditional ISO seven-layer OSI model. Information level standards represent the functionality of the system to be implemented.

NTCIP Application Level Application standards define the rules and procedures for exchanging information data. The rules may include definitions of proper grammar and syntax of a single statement, as well as the sequence of allowed statements. This is similar to combining words and phrases to form a sentence, or a complete thought, and defining the rules for greeting each other and exchanging information. These standards are roughly equivalent to the Session, Presentation and Application Layers of the OSI model.

NTCIP Transport Level Transport standards define the rules and procedures for exchanging the Application data between point 'A' and point 'X' on a network, including any necessary routing, message disassembly/re-assembly and network management functions. This is similar to the rules and procedures used by the telephone company to connect two remotely located telephones. Transportation level standards are roughly equivalent to the Transport and Network Layers of the OSI model.

NTCIP Subnetwork Level Subnetwork standards define the rules and procedures for exchanging data between two 'adjacent' devices over some communications media. This is equivalent to the rules used by the telephone company to exchange data over a cellular link versus the rules used to exchange data over a twisted pair copper wire. These standards are roughly equivalent to the Data Link and Physical Layers of the OSI model.

NTCIP Plant Level The Plant Level is shown in the NTCIP Framework only as a means of providing a point of reference to those learning about NTCIP. The Plant Level includes the communications infrastructure over which NTCIP communications standards are to be used and has a direct impact on the selection of an appropriate Subnetwork Level for use over the selected communications infrastructure. The NTCIP standards do not prescribe any one media type over another. In most cases, communications media selections are made early in the design phase.

The NTCIP Framework does not preclude combinations beyond those expressly indicated on the diagram.

Technical information

Originally, DVD recorders supported one of three standards: DVD-RAM, DVD-RW (using DVD-VR), and DVD+RW (using DVD+VR), none of which are directly compatible. As a general rule, however, most current drives support both the + and - standards, while few support the DVD-RAM standard, which is not directly compatible with standard DVD readers.

Recording speed is generally denoted in values of X (similar to CD-ROM usage), where 1X in DVD usage is equal to 1.321 MB/s, roughly equivalent to a 9X CD-ROM. In practice, this is largely confined to computer-based DVD recorders, since standalone units generally record in real time, that is, 1X speed. fetal doppler

DVD recorders use a laser (usually 650 nm red) to read and write DVDs. The reading laser is usually not stronger than 5 mW, while the writing laser is considerably more powerful. The faster the writing speed is rated, the stronger the laser is. DVD burner lasers often peak at about 100-400 mW in continuous wave (some are pulsed). Some laser hobbyists have discovered ways to extract the laser diode from DVD burners and modify them to create laser apparatus that can cause burning. heartbeat monitor

Computer-based DVD drives test glucose meter

Further information: Optical disc drive

DVD recorder drives have become standard equipment in many, though not all, computer systems currently on the market, after being initially popularized by the Pioneer/Apple SuperDrive; aftermarket drives as of early 2007 can cost as little as $23 . DVD recorder drives can be used in conjunction with DVD authoring software to create DVDs near or equal to commercial quality, and are also widely used for data backup and exchange. As a general rule, computer-based DVD recorders can also handle CD-R and CD-RW media; in fact, a number of standalone DVD recorders actually use drives designed for computers.

Most internal drives are designed with parallel ATA interfaces, with serial ATA becoming more readily available. External drives almost always use USB 2.0 or IEEE 1394, with eSATA becoming an option as well.

DVD recorder drives are required[by whom?]to respect DVD region codes when reading a disc, but do not impose a region code on written discs unless the code has specifically been written into the disc's content.

DVD duplication systems are generally built out of stacks of these drives, connected through a computer-based backplane.

Standalone DVD recorders

When the standalone DVD recorder first appeared on the Japanese consumer market in 1999, these early units were very expensive, costing between $2500 and $4000 USD. However, as of early 2007, DVD recorders from notable brands are selling for US$200 or 150 and less, with even lower "street prices". Early units supported only DVD-RAM and DVD-R discs, but the more recent units can record to all major formats DVD-R, DVD-RW, DVD+R, DVD+RW, DVD-R DL and DVD+R DL. Some models now include mechanical hard disk drive-based digital video recorders (DVRs) to improve ease of use. Standalone DVD recorders generally have basic DVD authoring software built in; however, the appearance of the finished DVD is very basic and usually completely under the control of the unit.

Some believed that DVD recorders would supersede the VCR as the standard television-recording device; however as technology progresses, Panasonic introduced the world's first Blu-ray disc recorder which is capable of recording both DVDs and Blu-ray discs.

DVD recorders have several technical advantages over VCRs, including:

Superior video and audio quality

Easy-to-handle smaller form-factor disc media, and more durable than magnetic tape.

Random access to video chapters without rewinding or fast-forwarding (serial access)

Onscreen multilingual subtitles and labeling not available on VCRs

Reduced playback wear and tear

High-quality digital copying, with little or no generation loss

Improved editing, at least on rewritable media

Playlisting

No risk of accidentally recording over existing content or unexpectedly running out of space during recording

Easy to find recordings due to chapter menus

It does have some disadvantages

Slow initial access/load times due to the optical nature of the disc

Limited rewritability on DVDRW(+RW) discs (typically around 1000). DVD-RAM is better suited for high frequency re-recording (around 100,000 rewrites)

Relatively short life of the laser diodes (average of about 2 years depending on usage).

However, an inconvenience exists in which DVDs recorded with DVD recorders must be finalized to view in other DVD players. (This disadvantage does not apply to DVD-RAM or DVD+RW discs, which require no finalization due to their 'random access' nature.) Also, the implementation of MPEG-2 compression used on most standalone DVD recorders is required to compress the picture data in real time, producing results that may not be up to the standard of professionally rendered DVD video, which can take days to compress.

The United States is converting its over-the-air television broadcasts to digital "ATSC" in June 2009, however this will have very limited impact in ending the need for DVD recorders to perform realtime MPEG-2 encoding or transcoding. The only setup where ATSC could conceivably eliminate MPEG-2 encoding/transcoding in a DVD recorder would be where an antenna is hooked directly into a DVD recorder that has an integrated ATSC tuner. Even then however, the DVD recorder will have to transcode the ATSC MPEG-2 into DVD-Video-legal MPEG-2 if the ATSC MPEG-2 stream isn't already DVD-Video-compatible. This would require transcoding for all high-definition broadcasts and some if not all standard-definition broadcasts. The same general situation applies to digital cable service; only DVD recorders with integrated digital cable ("QAM") tuners can possibly avoid transcoding, and then only if the digital cable system is already sending a DVD-Video-compatible MPEG-2 stream, which again requires transcoding of all HD content and some if not all SD content. All other setups (digital cable box's analog outputs to DVD recorder, satellite box's analog outputs to DVD recorder, DVD recorder tuning and recording analog cable channels which are still permitted after 2/2009, etc.) usually always involve an analog step with MPEG-2 encoding being necessary inside the DVD recorder.

A number of manufacturers have combined DVD recorders with mechanical hard disk drive-based digital video recorders, allowing for recording to large fixed disks, and the ability to view these recordings off the hard disk at a later date.

In Japan, AVCREC recorders, which are able to record MPEG-2 or AVC high definition video from ISDB broadcast with or without re-encoding, get increasingly popular. Initially, AVCREC recorders use DVD recordable discs, but newer models are able to record onto Blu-ray discs as well onto hard disk drives.

ATSC standalone DVD recorders

As a result of the North American digital switchover, tuner-equipped devices manufactured or imported into the United States are now required by the US Federal Communications Commission to include digital tuners.

This has caused most new VHS recorders to be implemented as DVD/VCR combo units, or to be manufactured without tuners. The US requirement of ATSC compatibility forces inclusion of MPEG-2 decoding hardware, which is already part of all DVD players but which otherwise would not have been needed in an analog-only VCR.

An ATSC-capable DVD unit can also serve as a more-powerful alternative to digital television adapters, which allow DTV reception with older NTSC analog televisions. The DVD recorders offer additional capabilities, such as automated VCR-style timeshifting of programming and a variety of output formats, that are deliberately not included in the most common mass-market US ATSC converters.

Unlike the more common digital television adapter boxes, newer DVD recorder units are able to tune both analog and digital signals - an advantage when receiving low-power television and foreign (analogue) signals. Some, however, do suffer from many of the same design limitations as the less costly converter boxes, including poorly-designed signal strength meters, incomplete display of broadcast program information, incompatibility with antenna rotators or CEA-909 smart antennas and inability to add digital channels without wiping out all existing channels and rescanning the entire band.

A DVD recording of an over-the-air HDTV broadcast is at DVD resolution, which is inferior to the original broadcast with 720p or 1080i resolution. Some units also provide limited USB or flash memory interface capability, often only supporting viewing of digital camera still photos or playback of MP3s with no ability to write video to these media.

A small number of DVD recorders are also capable of recording to SVCD, VCD and even Audio CD formats. Recording to DVDs can be done at different speeds giving between 1 and 6 hours on a standard (single sided 12 cm) blank DVD. With some trade off between recording time and video quality.

MiniDVD recorders

8 cm miniDVDs are widely used on some digital camcorders, primarily those meant for a consumer market ("point and shoot"); such discs are usually playable on a full-sized DVD player, but may not record on a full-sized DVD recorder system. Though popular for their convenience (in the manner of VHS-C), DVD camcorders are not considered suitable for more than casual use due to the much higher level of compression used compared to MiniDV and the difficulty of editing MPEG-2 video.

History

Merger

Main articles: Alliance UniChem and Boots Group popcorn poppers

Alliance Boots was formed following the merger of a pan-European company, Alliance UniChem Plc, and a British company, Boots Group PLC. Whilst the creation of Alliance Boots was billed as a "Merger" it was technically an acquisition of Alliance Unichem PLC by the larger Boots Group PLC, which then renamed itself "Alliance Boots". hobart mixer

Alliance UniChem was formed at the end of 1997, when Alliance Sant S.A. merged with the UK company UniChem PLC to form Alliance UniChem Plc, and between 1998 and 2006, Alliance UniChem expanded into additional markets throughout Europe and Russia with a widespread program of takeovers, resulting in the company expanding and entering the FTSE 100 share index in 2002. meat slicer

Alliance Sant stem from Alleanza Salute Italia, which was founded in 1977 by present Alliance Boots Executive Chairman Stefano Pessina. Through his investment vehicle Alliance Sant Participations S.A, at the time of the merger Pessina owned just under 15% of Alliance Boots plc (some 145,300,001 shares) together with 299,108 shares Pessina holds personally. Ornella Barra, Stefano Pessina's partner and director of Alliance Sant Participations S.A owned 559,021 shares. Taken together, the couple owned 15.106% of Alliance Boots plc.

John Boot opened his original shop in 1849 . Boots remained an independent company from its inception through to the merger with Alliance UniChem. Boots' business strategies have generally been successful, as evidenced by its steady, if unspectacular growth over the years. There have, however, been several unsuccessful strategies in pursuit of growth, such as locating Boots stores within larger Sainsbury out of town supermarkets at one point even considering the sale of sex toys in Boots stores..

In October 2005 it was announced, after a short period of speculation amongst financial analysts, that Boots would merge with Alliance UniChem in a deal valuing both companies equally and said to be worth around 7 billion.

The merger process completed without any major intervention from the Office of Fair Trading on Monday 31 July 2006, although 96 shops were sold to comply with a condition laid down by the OFT. Technically, the merger was in fact a takeover by Boots, with Boots Group PLC - the holding company of The Boots Company PLC - acquiring the entire share capital of Alliance UniChem and issuing 1.332 Boots Group PLC shares for every 1 Alliance UniChem share held. Upon completion of the process, Boots Group PLC renamed itself to Alliance Boots plc. The benefit of this process allowed The Boots Company PLC and Alliance UniChem Plc to remain intact under one parent company, and eliminating time consuming and expensive legal work which would have been necessary to merge the two companies together into one new company.

Following the merger process, former Boots Group shareholders held 50.2% of the new company, with former Alliance UniChem shareholders getting 49.8%.

Despite the Office of Fair Trading not imposing any restrictive conditions on the deal, the merger only received final approval in February 2006 after the Competition Appeal Tribunal rejected rival firm Celesio's challenge to the deal. Celesio own the Lloydspharmacy Chain.

Acquisition by KKR

On the 25 April 2007, Alliance Boots was approached with a buy-out offer by New York City-based Private Equity firm Kohlberg Kravis Roberts in conjunction with Alliance Boots' then Executive Deputy Chairman, Stefano Pessina, for an estimated 12.4billion. Alliance Boots has become the first company on the FTSE 100 share index to be bought-out by a private equity firm. On 25 July, it was reported that UK banks that are part of the debt syndication have had trouble obtaining buyers for the debt.

On 31 March 2008 Alliance Boots GmbH, of Zug, Switzerland, acquired the trading business from AB Acquisitions Holdings Limited (KKR and Pessina's acquistition vehicle) in exchange for the issue of share capital, and became a subsidiary of that company. The canton of Zug is a favoured location for major company headquarters due to its generous corporate tax regime.

Operations

Alliance Boots operations are split into three areas, Retail, Wholesale, and Contract Manufacturing.

Boots

Boots The Chemists forms the backbone of Alliance Boots retail operations. Nearly all the former Alliance Unichem stores have now been rebranded as Boots. Boots has a history stretching back over 150 years and is a familiar sight on Britain's high streets.

Boots outlets are typically larger than those of Alliance Pharmacy, often occupying prominent high street/city centre locations. Most branches have a pharmacy (only 300 of 3000 stores do not) and focus on healthcare, personal care and cosmetic products, with most stores selling over the counter medicines, many stores also feature traditional photo processing and/or a Kodak picture kiosk where users of digital cameras and camera phones can create professional quality prints. Larger stores usually offer a range of electrical equipment such as hairdryers, curlers and foot massagers, whilst selected stores often offer a range of sandwiches, baguettes, wraps, salads and beverages.

Over the last three years, Boots has opened 48 larger out of town stores to compete with out of town supermarkets and electrical outlets, over the past few years, Boots have suffered intensive competition from the major supermarket chains, especially Tesco and Asda stores featuring a pharmacy and photo processing area, and electrical retailers such as Argos and Dixons selling photographic and beauty electrical items. The pharmacy side of the business is also facing competition from community pharmacies with a stronger heathcare focus, such as Lloydspharmacy, Co-op and Rowlands.

Larger stores typically offer a variety of healthcare services in addition to dispensing prescriptions, such as flu vaccination, Cholesterol screening, weight loss advice, hair retention treatment, smoking cessation advice and products, and Chlamydia testing & treatment (private service). Boots is also a big player in the provision of services to Care Homes across the UK. Optician services are also offered in many larger stores, with Boots providing eye tests along with the sale of spectacles and contact lenses. Boots supplied 800,000 pairs of spectacles in 2005/2006

Boots has a well developed internet site www.boots.com which allows online shopping in the United States, Canada, Norway, Romania, Russia, Taiwan, United Arab Emirates, Kuwait and Thailand.

Advantage Card - billed as the most generous customer loyalty card in Britain, Boots Advantage card has 15,000,000 regular users and users earn 4 points (worth 1p each, so 4p per 1) for every 1 spent. (In Ireland, users earn 4c for every 1 spent).

Alliance Pharmacy

The original Alliance Pharmacies were typically smaller shops focusing mainly on filling prescriptions, selling healthcare products and providing medical advice. Alliance Pharmacies tend to be in less prominent locations, closer to GP surgeries or located in housing estates rather than town centres, in locations more suited to the needs of those needing prescriptions and over the counter medicines.

Since the merger, Alliance Pharmacy stores were re-branded to 'Your Local Boots Pharmacy' and now carry the Boots logo. The changes began in January 2008 and a majority of stores have now been rebranded.

Moss Pharmacies

E.Moss Limited was acquired by UniChem in 1991 and through 2005 was re-branded as Alliance Pharmacy. Any remaining Moss Pharmacy stores will be re-branded as Boots along with the Alliance Pharmacy stores.

Internationally

Alliance Boots operates a further 400 pharmacies in Norway, the Netherlands, Thailand, Republic of Ireland, Italy and Switzerland (through an associate) and has a presence in various other countries such as Russia, Romania, Canada and the USA through implants in other major retail partners. In Norway the group operates the Alliance Apotek chain with 140 outlets, and the Boots Apotek chain with 60 outlets.

Wholesale operations

Alliance Healthcare

Alliance Healthcare is the backbone of Alliance Boots wholesale and distribution service, with twice daily deliveries to around 5,700 pharmacy shops in the UK alone. Internationally, Alliance Boots distributes drugs and cosmetics to around 125,000 outlets and operates from 380 delivery depots.

In addition to supplying Alliance Pharmacies, the Alliance Healthcare distribution subsidiaries also deliver to NHS central warehouses and hospitals in the UK, along with private hospitals, GP surgeries, local health centres and private pharmacies throughout Europe, Asia and Australasia.

Almus

Almus is a brand of generic prescription drugs sold throughout the Alliance UniChem sphere of operations.

Almus is an umbrella brand for the wide range of lower cost generic medicines, which by the end of 2006 will total 200 different drugs and doses. Alliance Boots has placed considerable emphasis on the design of the packaging in an attempt to reduce the number errors by the dispensing chemist and by the patient relating to incorrect dosage which can result in either a dangerous accidental overdose or an equally dangerous under dose. Almus have won numerous awards for the design of their packaging and documentation.

Contract manufacturing operations

Boots Contract Manufacturing

BCM Limited is the manufacturing subsidiary of Alliance Boots and manufactures a range of own-brand and third-party medicines, and cosmetic product ranges such as No 7, Kangol, Toni & Guy, FCUK, Soltan and Botanics. Some are sold through Boots stores whilst others are sold through third party stores such as French Connection and Toni & Guy. Boots Contract Manufacturing has facilities in the UK, Germany, France and Poland.

BCM Cosmtique is the company's manufacturing division in France.

BCM Kosmetik is the company's manufacturing division in Germany.

BCM Specials manufacture bespoke non-licenced medicines for UK hospital and retail pharmacies.

Subsidiary companies

Alliance Boots plc is the direct parent company of The Boots Company plc and Alliance UniChem plc, with The Boots Company plc and Alliance UniChem plc remaining parent companies of their respective subsidiaries. There has been no change in the structure of either company during the merger process.

Home automation

Home wiring history

A typical domestic patch panel.

Traditionally, homes have been wired for four systems: power, telephones, cable TV outlets, and a doorbell. Typically, components and wiring for these are kept within a closet or a patch panel. motorola bluetooth hs850

Home automation has been around since World War I. A television remote was first patented in 1950,[citation needed] and a remote control device was first used by the Germans in World War I to control motorboats. From there, the evolution of controllers and automation has been growing and still continue to grow to this day. e2c

In advanced installations, rooms can sense not only the presence of a person but know who that person is and perhaps set appropriate lighting, temperature, music or television levels taking into account the day of the week, the time of day, and other factors. hs850

Other automated tasks may include setting the air conditioning to an energy saving setting when the house is unoccupied, and restoring the normal setting when an occupant is about to return. More sophisticated systems can maintain an inventory of products, recording their usage through an RFID tag, and prepare a shopping list or even automatically order replacements.

Some practical implementations of home automation are for example when an alarm detects a fire or smoke condition, then all lights in the house will blink to alert occupants. If the house is equipped with a home theater, a home automation system can shut down all audio and video components to alert the user to a possible fire or a burglar.

Standards and bridges

Specific domestic wiring and communication standards include BACnet, INSTEON, X10, PLC BUS, KNX (standard), System Box, LonWorks, C-Bus, SCS BUS with OpenWebNet, Universal powerline bus (UPB), UPnP, ZigBee and Z-Wave that will allow for control of most applications. Some standards use communication and control wiring, some embed signals in the powerline, some use radio frequency (RF) signals, and some use a combination of several methods. Control wiring is hardest to retrofit into an existing house. Some appliances include USB that is used to control it and connect it to a domotics network. Bridges translate information from one standard to another (eg. from X10 to European Installation Bus).

System

The elements of a domotics system are:

hardware controllers or software controllers

sensors

actuators

Architecture

From the point of view of where the intelligence of the domotic system resides, there are three different architectures:

Centralized Architecture: a centralized controller receives information of multiple sensors and, once processed, generates the opportune orders for the actuators.

Distributed Architecture: all the intelligence of the system is distributed by all the modules that are sensors or actuators. Usually it is typical of the systems of wiring in bus.

Mixed Architecture: systems with decentralized architecture as far as which they have several small devices able to acquire and to process the information of multiple sensors and to transmit them to the rest of devices distributed by the house.

Tasks

HVAC

Heating, Ventilation and Air Conditioning (HVAC) solutions include temperature and humidity control (climotics). This is generally one of the most important aspects to a homeowner. An Internet-controlled thermostat, for example, can both save money and help the environment, by allowing the homeowner to control the building's heating and air conditioning systems remotely.

Lighting

Lighting control systems involves aspects related to controlling electric lights.

Extinguished general of all the lights of the house

Automation of switched off / ignition in every point of light

Regulation of the illumination according to the level of ambient luminosity

Natural lighting

Natural lighting control involves controlling window shades, LCD shades, draperies and awnings. Recent advances include use of RF technology to avoid wiring to switches and integration with third party home automation systems for centralized control.

Audio

Major companies associated with Audio Distribution include: Crestron, [Russound], NuVo, Control 4, and Niles.

There are three components that allow the consumer to listen to audio throughout your home, or business:

CAT 5e/ CAT6 cable from Audio central unit.

2 sets of speaker cabling (4ply from amplifier, and 2 ply from key pad to ceiling or wall speakers).

A keypad to control your volume and sources.

This category includes audio switching and distribution. Audio switching determines the selection of an audio source. Audio distribution allows an audio source to be heard in one or more rooms. This feature is often referred to as 'multi-zone' audio.

Video

This includes video switching and distribution, allowing a video source to be viewed on multiple TVs. This feature is often referred to as 'multi-zone' video.

Integration of the intercom to the telephone, or of the video door entry system to the television set, allowing the residents to view the door camera automatically.

Security

Control and integration of security systems.

With Home Automation, the consumer can select and watch cameras live from an Internet source to their home or business. Security cameras can be controlled, allowing the user to observe activity around a house or business right from a Monitor or touch panel. Security systems can include motion sensors that will detect any kind of unauthorized movement and notify the user through the security system or via cell phone.

This category also includes control and distribution of security cameras (see surveillance).

Detection of possible intrusion

sensors of detection of movement

sensors of magnetic contact of door/window

sensors of glass breaking

sensors of pressure changes

Simulation of presence.

Detection of fire, gas leaks, water leaks (see fire alarm and gas alarm)

Medical alert. Teleassistance.

Precise and safe closing of blinds.

Intercoms

An intercom system allows communication via a microphone and loud speaker between multiple rooms.

Ubiquity in the external control as much internal, remote control from the Internet, PC, wireless controls (p.ej. PDA with WiFi), electrical equipment.

Transmission of alarms.

Intercommunications.

Robotics

Control of home robots, using if necessary domotic electric beacon.

Home robot communication (i.e. using WiFi) with the domotic network and other home robots.

Other systems

A homemade Internet-enabled cat feeder.

Using special hardware, almost any device can be monitored and controlled automatically or remotely.

Including:

Coffee pot

Garage door(s)

Pet feeding and watering

Plant watering

Pool pump(s) and heater, Hot tub and Spa

Sump Pump (need info and links)

Costs

An automated home can be a very simple grouping of controls, or it can be heavily automated where any appliance that is plugged into electrical power is remotely controlled. Costs mainly include equipment, components, furniture, and custom installation.

Smart Grid

In 2009 President Barack Obama asked the United States Congress "to act without delay" to pass legislation that included doubling alternative energy production in the next three years and building a new electricity "smart grid". On April 13, 2009, George W. Arnold was named the first National Coordinator for Smart Grid Interoperability. In June 2009, the NIST announced a smart grid interoperability project via IEEE P2030.

Home automation technologies like Zigbee, INSTEON and Zwave are viewed as integral additions to the Smart Grid. The ability to control lighting, appliances, HVAC as well as Smart Grid applications (load shedding, demand response, real-time power usage and price reporting) will become vital as Smart Grid initiatives are rolled out.

Implementations

Dreamcast

The second generation PowerVR2 ("PowerVR Series 2", chip codename "CLX2") chip found a market in the Dreamcast console between 1998 and 2001. As part of an internal competition at Sega to design the successor to the Saturn, the PowerVR2 was licensed to NEC and was chosen ahead of a rival design based on the 3dfx Voodoo 2. Thanks to the performance of the PowerVR2, several Dreamcast games such as Quake III Arena could rival their PC counterparts in quality and performance. However, the success of the Dreamcast meant that the PC variant, sold as Neon 250, appeared a year late to the market and was at that time mid-range at best. motorola bluetooth hs850

KYRO and KYRO II e2c

Kyro II. hs850

In 2001, STMicroelectronics adopted the third generation PowerVR3 for their STG4000 KYRO and STG 4500 KYRO II (displayed) chips. The STM PowerVR3 KYRO II, released in 2001, was able to rival the more expensive ATI Radeon DDR and NVIDIA GeForce 2 GTS in graphic benchmarks of the time, despite not having hardware Transform and lighting (T&L). Unfortunately, as games were increasingly optimized for hardware T&L, the KYRO II lost its performance advantage. Today it is no longer supported by new released games.

STM's STG5000 chip was based upon the PowerVR4, which did include hardware T&L but it never came to commercial fruition.

Technology

The PowerVR chipset uses a unique approach to rendering a 3D scene, known as tile-based deferred rendering (often abbreviated as TBDR). As the polygon generating program feeds triangles to the PowerVR (driver) it stores them in memory in a triangle strip or an indexed format. Unlike other architectures, polygon rendering is (usually) not performed until all polygon information has been collated for the current frameence rendering is deferred.

In order to render, the display is split into rectangular sections in a grid pattern. Each section is known as a tile. Associated with each tile is a list of the triangles that visibly overlap that tile. Each tile is rendered in turn to produce the final image.

Tiles are rendered using a process similar to ray-casting. Rays are cast onto the triangles associated with the tile and a pixel is rendered from the triangle closest to the camera. The PowerVR hardware typically calculates the depths associated with each polygon for one tile row in 1 cycle.

This method has the advantage that, unlike a more traditional z-buffered rendering pipeline, no calculations need to be made to determine what a polygon looks like in an area where it is obscured by other geometry. It also allows for correct rendering of partially transparent polygons, independent of the order in which they are processed by the polygon producing application. (This capability was only implemented in Series 2 and one MBX variant. It is generally not included for lack of API support and cost reasons.) More importantly, as the rendering is limited to one tile at a time, the whole tile can be in fast onchip memory, which is flushed to video memory before processing the next tile. Under normal circumstances, each tile is visited just once per frame.

PowerVR is not the only pioneer of tile based deferred rendering, but the only one to successfully bring a TBDR solution to market. Microsoft also conceptualised the idea with their abandoned Talisman project. Gigapixel, a company that developed IP for tile-based deferred 3D graphics, was purchased by 3dfx, who were subsequently purchased by Nvidia. Nvidia currently has no official plans to pursue tile-based rendering.

Intel uses a similar concept in their integrated graphics solutions. However, their method, coined zone rendering, does not perform full hidden surface removal (HSR) and deferred texturing, therefore wasting fillrate and texture bandwidth on pixels that are not visible in the final image.

Recent advances in hierarchical Z-buffering have effectively incorporated ideas previously only used in deferred rendering, including the idea of being able to split a scene into tiles and of potentially being able to accept or reject tile sized pieces of polygon.

See Deferred shading for more details about how recent techniques make use of new shader models to implement deferred rendering.

MBX

With KYRO 3 (2D/3D AIB) products shelved due to STMicro closing its graphics division, PowerVR concentrated on the portable market with its next design, the low power PowerVR MBX. It, and its SGX successors, have become the de facto standards for mobile 3D, having been licensed by seven of the top ten semiconductor manufacturers including Intel, Texas Instruments, Samsung, NEC, NXP Semiconductors, Freescale, Renesas and Sunplus, and are in use in many high-end cellphones including the iPhone, Nokia N900, Nokia N95, Sony Ericsson P1 and Motorola RIZR Z8.

There are two variants: MBX and MBX Lite. Both have the same feature set. MBX is optimized for speed and MBX Lite is optimized for low power consumption. A MBX can be paired up with an FPU, Lite FPU, VGP Lite and VGP.

Coffee and the environment


China Product

Introduction

It seems as though consuming a morning cup of coffee has always been a part of the routine of the average American. However, up until recently, citizens have not put a great deal of thought into where it is that their prized beverage has come from. Recently, coffee companies large and small have begun to take into account the United States' love of specialized coffee, as well as its need to help the environment. Companies like Eco Organic Coffee ("Coffee with a conscience", 1997) and Starbucks have begun to value the healthy growth of the coffee beans that they purchase. They look at whether or not they were, in fact, raised in an environmentally-friendly manner, such as through shade farms rather than sun farms (Anonymous, 2008). This socially responsible coffee can be found in forty countries, with leading locations like Peru, Ethiopia, and Mexico ("Facts about organic," 2008). In order to fully understand the goal of the coffee companies' production of socially responsible coffee, it is first necessary to look at the positive and negative effects of differing types of coffee growth, as well as ways to continue the growth of environmentally friendly coffee beans.

Coffee Companies and the Environment used riding mowers

While coffee companies have typically focused primarily on profit, some coffee companies are now placing greater emphasis on the environmental and social costs associated with coffee production, processing and trade. self propelled lawnmower

Shade-grown Coffee Farms reel lawn mowers

Traditionally coffee plants were grown under the shade of trees, which provided natural habitat for many animals and insects, roughly approximating the biodiversity of a natural forest . The trees provided a moderate climate for the plants, and leaves that dropped from the shade trees enriched the soil. Farmers also used compost coffee pulp before chemical fertilizers were available. They typically rotated crops and cultivated food alongside their cash crops, which provided additional income and food security.[citation needed]

In understanding the benefits of this shade-grown coffee, it is first necessary to understand its many types. Rustic farms are typically small, family farms, with little alternation to the original forests. There is typically 70 to 100 percent shade cover. Traditional polyculture includes a mixture of the native trees and planted trees with 60 to 90 percent shade cover. Commercial polyculture, with 30 to 60 percent shade covering, has even more trees removed to increase the number of coffee plants. Finally, shaded monoculture includes dense plantings of coffee beneath merely 10 to 30 percent of shade covering. While rustic farms are the most natural, each of these shade farms is more environmentally friendly than the typical sun farm, which provides nearly no shade covering at all ("What is shade," 2007). With regards to work conditions, the shade helps farmers to avoid the high temperatures and humidity. Additionally, shade farms help to harbor diversity, prevent soil erosion, isolate carbon, and even save forests (Blackman, Avalos-Sartorio, & Chow, 2007).

Along with the other multitudinous benefits of shade farms, if the destruction of forests can be prevented, many organisms will be able to turn coffee trees into their humble homes, where they can both live and reproduce. Coffee trees provide a home for a variety of types of birds. In a study done on bird populations found in Central Guatemala, multiple shade and sun-grown coffee farms were studied to determine the species of birds present in different habitats. It was concluded that shade-farms provide a habitat for woodland residents and migrants that sun-farms are not capable of making available. More species of birds have a tendency to migrate towards the diversely planted canopy trees, since the multitude of types resembled the many trees in their natural forest habitat ("Coffee with a conscience", 1997). "The loss of the shade trees on such a large scalecaused an estimated 20% decline in migratory bird populations in the last ten years, due to habitat loss" ("Shade Grown Coffee," 2008). Shade-grown coffee plantation habitats are necessary for the survival of many birds restricted to forest habitats, especially as the international destruction of natural forests increases. For instance, redstarts, black-throated green warblers, yellow-throated, and solitary vireos depend on shade-grown coffee farms ("Migrants and Coffee," 2008).

Sun-Grown Coffee Farms

However, in the 1970s and 1980s, during the "Green Revolution," the US Agency for International Development and other groups gave $80 million to plantations in Latin America for advancements to go along with the general shift to technified agriculture.[citation needed] These plantations replaced their shade grown techniques with sun cultivation techniques to increase yields, which in turn destroyed vast forests and biodiversity. In addition, the decline of coffee prices and the expansion of cities caused many farms in Central America to be destroyed and replaced by urban buildings and conventional farming. In this region, less than 20 percent of the country's forests still remain. This causes a loss of organisms and many cases of soil erosion. Sun cultivation involves cutting down trees, and high inputs of chemical fertilizers and pesticides. Environmental problems, such as deforestation, pesticide pollution, habitat destruction, soil and water degradation, are the effects of most modern coffee farms, and the biodiversity on the coffee farm and in the surrounding areas suffer. According to "Coffee with a conscience," in the past 20 years, "30 to 40 percent of the plantations in northern Latin America alone have been converted to sun farms" (1997, p. 51). Unless problems regarding farm investment and yields, debt, poverty, urbanization, migration, and weak land use regulations can be addressed, shade-farms will soon cease to exist, along with the socially responsible coffee that they so generously produce (Blackman, Avalos-Sartorio, & Chow, 2007). While many Americans are aware of the fact that certain coffee products impact the environment in more positive ways than others, many are unaware of the detrimental effects of sun-grown coffee on the environment. Sun-grown coffee farms require fertilizers, pesticides, and other harmful chemicals to protect the coffee beans from the sun's brutal rays (Anonymous, 2008). The combination of these substances has harmed the air, the water, and the habitats of many birds ("Coffee with a conscience", 1997, p. 51). In addition, the lack of underbrush has caused an erosion of hills, hence the destruction of many species' habitats (Anonymous, 2008). Prior to 1972, sun farms were not in existence. However, as is classic of America, someone found a way to increase the production of a crop that was found to be highly valuable. Coffee beans became smaller and easier to harvest. Unfortunately, these new beans had to be grown in direct sunlight. Along with this new trend, came the devastating effects of sun farms on the environment and its species ("Shade Grown Coffee," 2008). While the American government knows the effects of sun-farms, they seem incredibly preoccupied with the speed with which they produce coffee, as opposed to the results. For instance, the United States government handed over $80 million to Latin America to update their coffee growing practices with pesticides and fertilizers (Hudson and Hudson, 2004). It seems apparent that something must be done about these sun farms to prevent their devastating effects on the depleting environment. The solution is simple: the use of shade-grown coffee plantations.

Water: Another Coffee Issue

Another issue concerning coffee is its use of water. According to New Scientist, it takes about 140 litres of water to produce one cup of coffee, and the coffee is often grown in countries where there is a water shortage, like Ethiopia.

Conclusion

According to Mark and Ian Hudson, "A recent study by the Guatemalan Commission for the Verification of Corporate Codes of Conduct found half the workers on fincas in that country earning less than $3 per day for picking 100 pounds of coffee" (2004, p. 13). Therefore, the "fair-trade" option was developed to give $1.26 or more per pound of coffee to the workers. This does not seem like a great deal of money, but it is a start in helping the workers in Central America provide for themselves and for their families. Since shade-grown coffee requires more human-labor than sun-grown, America is saving the environmentally friendly coffee in using free-trade to take care of the workers, thus continuing shade-grown coffee production (Hudson & Hudson, 2004).There has been a return to both traditional and new methods of growing shade-tolerant varieties.[citation needed] Shade-grown coffee can often earn a premium as a more environmentally sustainable alternative to mainstream sun-grown coffee. After all, coffee is not only considered a necessity in the life of many Americans, but "is the world's second most valuable market commodity after petroleum" (Hudson & Hudson, 2004, p. 13). Since the United States is responsible for the purchase of 25% of the coffee beans found in the local market, it seems that they should also be responsible for how their imported product is affecting the ever-changing environment (Hudson & Hudson, 2004). In order to do this, it is first necessary to look at the positive and negative effects of differing types of coffee growth, as well as ways to continue the growth of environmentally friendly coffee beans.
