59-711: TAP, initially known as Motorola Page Entry (PET) was adopted in September 1988, by the Personal Communication Industry Association . TAP defines an industry standard for sending alphanumeric messages to pagers. TAP was also known as IXO protocol. Originally, devices like the IXO Device were used to send Alphanumeric Pages using TAP. Later, Motorola would create a similar device called the AlphaMate . The standard protocol

118-408: A wall charger , power adapter , power brick , or wall wart ) is a type of external power supply , often enclosed in a case similar to an AC plug . AC adapters deliver electric power to devices that lack internal components to draw voltage and power from mains power themselves. The internal circuitry of an external power supply is often very similar to the design that would be used for

177-529: A French defense firm. Motorola's biometric business unit was headquartered in Anaheim, California. The deal closed in April 2009. The unit became part of Sagem Morpho , which was renamed MorphoTrak . On March 26, 2008, Motorola's board of directors approved a split into two different publicly traded companies. This came after talk of selling the company to another corporation. These new companies would comprise

236-708: A ban on the use of water that lasted three days and affected almost 5000 people in the area. Motorola was found to be the main source of the TCE, an industrial solvent that is thought to cause cancer. The TCE contamination was caused by a faulty blower on an air stripping tower that was used to take TCE from the water, and Motorola has attributed the situation to operator error. Of eighteen leading electronics manufacturers in Greenpeace 's Guide to Greener Electronics (October 2010), Motorola shared sixth place with competitors Panasonic and Sony . Motorola scored relatively well on

295-458: A built-in or internal supply. When used with battery -powered equipment, adapters typically charge the battery as well as powering the equipment. Aside from obviating the need for internal power supplies, adapters offer flexibility: a device can draw power from 120 VAC or 230 VAC mains, vehicle battery, or aircraft battery, just by using different adapters . Safety can be another advantage, as hazardous 120 or 240 volt mains power

354-559: A case, unplug them all, then plug them back in one by one until the culprit or culprits is found. External AC adapters are widely used to power small or portable electronic devices. The advantages include: A survey of consumers showed widespread dissatisfaction with the cost, inconvenience, and wastefulness of the profusion of power adapters used by electronic devices. The issue of inefficiency of some power supplies has become well known, with U.S. president George W. Bush referring in 2001 to such devices as "Energy Vampires". Legislation

413-600: A charger similar in most respects to that of the GSMA/OMTP proposal and to the European Common external power supply . The ITU recommendation was expanded and updated in June, 2011. The hope is to markedly reduce the profusion of non-interchangeable power adapters. The European Union defined a Common external power supply for "hand-held data-enabled mobile phones" ( smartphones ) sold from 2010, intended to replace

472-748: A de facto standard in low-power AC adapters for many portable devices. In addition to serial digital data exchange, the USB standard also provides 5 VDC power , up to 500 mA ( 900 mA over USB 3.0). Numerous accessory gadgets (" USB decorations ") were designed to connect to USB only for DC power and not for data interchange. The USB Implementers Forum in March, 2007 released the USB Battery Charging Specification which defines, "...limits as well as detection, control and reporting mechanisms to permit devices to draw current in excess of

531-595: A few watts to 35 watts of power in that state. The report concluded that about 32 billion kilowatt-hours (kWh) per year, about 1% of total electrical energy consumption, could be saved in the United States by replacing all linear power supplies (average efficiency 40–50%) with advanced switching designs (efficiency 80–90%), by replacing older switching supplies (efficiencies of less than 70%) with advanced designs (efficiency of at least 80%), and by reducing standby consumption of supplies to not more than 1 watt. Since

590-499: A further 4,000 job cuts in June and another 20% cut of its research division a few days later. In July 2008, a large number of executives left Motorola to work on Apple Inc. 's iPhone . The company's handset division was also put on offer for sale. Also that month, analyst Mark McKechnie from American Technology Research said that Motorola "would be lucky to fetch $ 500 million" for selling its handset business. Analyst Richard Windsor said that Motorola might have to pay someone to take

649-408: A high direct voltage driving a switching circuit, which contains a transformer operating at a high frequency and outputs direct current at the desired voltage. The high-frequency ripple is more easily filtered out than mains-frequency. The high frequency allows the transformer to be small, which reduces its losses; and the switching regulator can be much more efficient than a linear regulator. The result

708-560: A more central player in the early stages of the GSM standardization process in 1987. With this addition Motorola strengthened its position in Europe significantly. As Motorola's European development arm, Storno developed a GSM terminal in 1992. On January 29, 1988, Motorola sold its Arcade, New York facility and automotive alternators, electromechanical speedometers and tachometers products to Prestolite Electric . In 1996, Motorola released

767-468: A much more constant voltage than unregulated supplies as the input voltage and the load current vary. When introduced, their prices were high, but by the early 21st century the prices of switch-mode components had dropped to a degree which allowed even cheap supplies to use this technology, saving the cost of a larger and heavier mains-frequency transformer. Some universal adapters automatically set their output voltage and maximum current according to which of

826-587: A range of interchangeable tips is fitted; tips are available to fit and supply appropriate power to many notebook computers and mobile devices. Different tips may use the same connector, but automatically supply different power; it is essential to use the right tip for the apparatus being powered, but no switch needs to be set correctly by the user. The advent of switch-mode power supplies has allowed adapters to work from any AC mains supply from 100 to 240 V with an appropriate plug; operation from standard 12 V DC vehicle and aircraft supplies can also be supported. With

885-527: A shift towards the micro-USB and mini-USB connectors, which are electrically compatible in function to the original USB connector but physically smaller. In 2012, a USB Power Delivery Specification was proposed to standardize delivery of up to 100 watts, suitable for devices such as laptop computers that usually depend on proprietary adapters. The ITU published Recommendation ITU-T L.1000, "Universal power adapter and charger solution for mobile terminals and other hand-held ICT devices", which specifies

944-484: A very wide range of voltages and frequencies; a single 100–240 VAC unit will handle almost any mains supply in the world. Many inexpensive switched-mode AC adapters do not implement adequate filtering and/or shielding for electromagnetic interference that they generate. The nature of these high speed, high-energy switching designs is such that when these preventative measures are not implemented, relatively high energy harmonics can be generated, and radiated, well into

1003-489: Is ASCII with XON/XOFF flow control, using a 10-bit code (1 start bit, 7 data bits, even parity, 1 stop bit). No echo shall be employed in full duplex mode. This technology-related article is a stub . You can help Misplaced Pages by expanding it . Motorola Motorola, Inc. ( / ˌ m oʊ t ə ˈ r oʊ l ə / ) was an American multinational telecommunications company based in Schaumburg, Illinois . It

1062-462: Is a market for replacement adapters. The replacement must match input and output voltages, match or exceed current capability, and be fitted with a matching connector. Many electrical products are poorly labeled with information concerning the power supply they require, so it is prudent to record the specifications of the original power supply in advance, to ease replacement if the original is later lost. Careful labeling of power adapters can also reduce

1121-410: Is a much more efficient, smaller, and lighter device. Safety is ensured, as in the older linear circuit, because a transformer still provides galvanic isolation . A linear circuit must be designed for a specific, narrow range of input voltages (e.g., 220–240 VAC) and must use a transformer appropriate for the frequency (usually 50 or 60 Hz), but a switched-mode supply can work efficiently over

1180-587: Is being enacted in the EU and a number of U.S. states to reduce the level of energy wasted by some of these devices. Such initiatives include standby power and the One Watt Initiative . But others have argued that these inefficient devices are low-powered, e.g., devices that are used for small battery chargers , so even if they have a low efficiency, the amount of energy they waste is less than 1% of household consumption of electric energy. Considering

1239-436: Is released as heat , an inefficient power supply is hot to the touch, as is one that wastes power without an electrical load. This waste heat is itself a problem in warm weather, since it may require additional air conditioning to prevent overheating, and even to remove the unwanted heat from large supplies. External power adapters can fail, or can become separated from the product they are intended to power. Consequently, there

1298-422: Is transformed to a lower, safer voltage at the wall outlet before going into the appliance handled by the user. Originally, most AC/DC adapters were linear power supplies , containing a transformer to convert the mains electricity voltage to a lower voltage, a rectifier to convert it to pulsating DC , and a filter to smooth the pulsating waveform to DC, with residual ripple variations small enough to leave

1357-623: The Edward S. Rogers, Sr. company in 1925 as a complement to his line of "battery less" radio receivers . Another early producer of battery eliminators was the Galvin Manufacturing Corporation (later known as Motorola ), which was opened on September 25, 1928 by Paul Galvin and his brother Joseph E. Galvin. In early laptop computers, the power supply units were internal like in desktop computers . To facilitate portability by sparing physical space and reducing

1416-835: The Motorola Droid , was released in 2009 (the GSM version launched a month later, in Europe, as the Motorola Milestone). The handset division, along with the cable set-top box and modem businesses, were later spun off into Motorola Mobility. Motorola was founded in Chicago, Illinois , as Galvin Manufacturing Corporation (at 847 West Harrison Street) in 1928. Paul Galvin wanted a brand name for Galvin Manufacturing Corporation's new car radio, and created

1475-581: The Motorola StarMax , which was a Macintosh clone that was licensed by Apple and it came with System 7 . However, with the return of Steve Jobs to Apple in 1997, Apple released Mac OS 8 . Because the clone makers' licenses were valid only for Apple's System 7 operating system, Apple's release of Mac OS 8 left the clone manufacturers unable to ship a current Mac OS version without negotiation with Apple. A heated telephone conversation between Jobs and then Motorola CEO Christopher Galvin resulted in

1534-514: The U.S. Federal Communications Commission (FCC) approved the DynaTAC 8000X telephone, the world's first commercial cellular device. By 1998, cellphones accounted for two thirds of Motorola's gross revenue. In 1986 Motorola acquired Storno resulting in a whole new range of innovative communication products for the new owner, including the NMT , an automatic cellular phone system, and made Motorola

1593-477: The U.S. state of Illinois) included the Village of River Forest, Village of Bellwood Police Department, City of Evanston Police, Illinois State Highway Police, and Cook County (Chicago area) Police. Many of Motorola's products have been radio-related, starting with a battery eliminator for battery powered radios (during the burgeoning electrification of rural homes), through the first hand-held walkie-talkie in

1652-423: The USB 2.0 specification for charging ...". Electric fans, lamps, alarms, coffee warmers, battery chargers, and even toys have been designed to tap power from a USB connector. Plug-in adapters equipped with USB receptacles are widely available to convert 120 VAC or 240 VAC power or 12 VDC automotive power to 5 VDC USB power (see photo at right). The trend towards more-compact electronic devices has driven

1711-490: The appropriate adapter, accessories, and tips, a variety of equipment can be powered from almost any source of power. A "Green Plug" system has been proposed, based on USB technology, by which the consuming device would tell the external power supply what kind of power is needed. A battery eliminator is an adapter intended to allow a device intended for battery operation, such as a radio, to be operated from an AC outlet. Early commercial battery eliminators were produced by

1770-531: The business units of Motorola Mobile Devices and Motorola Broadband & Mobility Solutions. Originally it was expected that this action would be approved by regulatory bodies and complete by mid-2009, but the split was delayed due to company restructuring problems and the 2008–2009 extreme economic downturn. On February 11, 2010, Motorola announced it would separate into two independent, publicly traded companies. The cell phone and cable television equipment businesses would spin off to form Motorola Mobility , while

1829-541: The chemicals criteria and has a goal to eliminate PVC plastic and Brominated flame retardants (BFRs), though only in mobile devices and not in all its products introduced after 2010, despite the fact that Sony Ericsson and Nokia were already there. All of its mobile phones were now PVC-free and it had two PVC and BFR-free mobile phones, the A45 ECO and the GRASP; all chargers were also free from PVC and BFRs. The company

1888-551: The company reported a profit of $ 162 million, which compared very favorably to the $ 26 million earned for the same period the year before. Its Mobile Devices division reported, for the first time in years, earnings of $ 87 million. Motorola, Inc., along with the Arizona Water Co. had been identified as the sources of trichloroethylene (TCE) contamination that took place in Scottsdale, Arizona . The malfunction led to

1947-465: The division off the company's hands, and that Motorola may even exit the handset market altogether. Its global market share has been on the decline; from 18.4% of the market in 2007 the company had a share of just 6.0% by Q1 2009, but at last, Motorola scored a profit of $ 26 million in Q2 and showed an increase of 12% in stocks for the first time after losses in many quarters. During the second quarter of 2010,

2006-453: The famous words "That's one small step for man, one giant leap for mankind" from the Moon on a Motorola transceiver. In 1973, Motorola demonstrated the first hand-held portable telephone. In 1974, Motorola introduced its first microprocessor, the 8-bit MC6800 , used in automotive, computing and video game applications. The 6800 was the basis for the more popular MOS Technology 6502 which

2065-404: The gigahertz range can be degraded if the receiving antennae are very close to a radiating AC adapter. A determination of if interference is coming from a specific AC adapter can be made simply by unplugging the suspect adapter while observing the amount of interference received in the problem radio band. In a modern household or business environment, there may be multiple AC adapters in use; in such

2124-565: The intellectual property of Sendo for $ 30,000 and paid £362,575 for the plant, machinery and equipment. In June 2006, Motorola acquired the software platform ( AJAR ) developed by the British company TTP Communications plc. Later in 2006, the firm announced a music subscription service named iRadio . The technology came after a break in a partnership with Apple Computer (which in 2005 had produced an iTunes compatible cell phone ROKR E1 , and most recently, mid-2007, its own iPhone ). iRadio

2183-736: The likelihood of a mixup which could cause equipment damage. Some "universal" replacement power supplies allow output voltage and polarity to be switched to match a range of equipment. With the advent of switch-mode supplies, adapters which can work with any voltage from 110 VAC to 240 VAC became widely available; previously either 100–120 VAC or 200–240 VAC versions were used. Adapters which can also be used with motor vehicle and aircraft power (see EmPower ) are available. Four-way X connectors or six-way star connectors , also known as spider connectors , with multiple plug sizes and types are common on generic power supplies. Other replacement power supplies have arrangements for changing

2242-532: The many incompatible proprietary power supplies and eliminate waste by reducing the total number of supplies manufactured. Conformant supplies deliver 5 VDC via a micro-USB connector, with preferred input voltage handled ranging from 90 to 264 VAC. In 2006 Larry Page , a founder of Google , proposed a 12 V and up to 15 A standard for almost all equipment requiring an external converter, with new buildings fitted with 12 VDC wiring, making external AC-to-DC adapter circuitry unnecessary. IEC has created

2301-680: The name "Motorola" by linking "motor" (from motor car) with "ola" (from Victrola ), which was also a popular ending for many companies at the time, e.g. Moviola , Crayola . The company sold its first Motorola branded radio on June 23, 1930, to Herbert C. Wall of Fort Wayne, Indiana, for $ 30. The Motorola brand name became so well known that Galvin Manufacturing Corporation later changed its name to Motorola, Inc., in 1947. Galvin Manufacturing Corporation began selling Motorola car-radio receivers to police departments and municipalities in November 1930. The company's first public safety customers (all in

2360-481: The nominal "name plate" voltage, which could damage the load. If they are heavily loaded, the output voltage may droop appreciably, in some cases well below the nominal label voltage even within the nominal rated current, causing the equipment being supplied to malfunction or be damaged. Supplies with linear (as against switched) regulators are heavy, bulky, and expensive. Modern switched-mode power supplies (SMPSs) are smaller, lighter, and more efficient. They put out

2419-585: The power connector, with four to nine different alternatives available when purchased in a set. This allows many different configurations of AC adapters to be put together, without requiring soldering. Philmore and other competing brands offer similar AC adapters with interchangeable connectors. The label on a power supply may not be a reliable guide to the actual voltage it supplies under varying conditions. Many low-cost power supplies are " unregulated ", in that their voltage can change considerably with load. If they are lightly loaded, they may put out much more than

2478-423: The powered device unaffected. Size and weight of the device was largely determined by the transformer, which in turn was determined by the power output and mains frequency . Ratings over a few watts made the devices too large and heavy to be physically supported by a wall outlet. The output voltage of these adapters varied with load; for equipment requiring a more stable voltage, linear voltage regulator circuitry

2537-477: The radio portion of the spectrum. The amount of RF energy typically decreases with frequency; so, for instance, interference in the medium wave (US AM) broadcast band in the one megahertz region may be strong, while interference with the FM broadcast band around 100 megahertz may be considerably less. Distance is a factor; the closer the interference is to a radio receiver, the more intense it will be. Even WiFi reception in

2596-470: The remainder of Motorola, Inc., which comprised the government and enterprise equipment businesses, would become Motorola Solutions . The split was closed on January 4, 2011. Motorola Mobility was eventually acquired by Google on May 22, 2012. Google later sold Motorola Mobility's cable equipment business to Arris Group in December 2012, and Motorola Mobility itself to Lenovo on October 30, 2014. At

2655-518: The report was published, SMPSs have indeed replaced linear supplies to a great extent, even in wall warts. The 2002 report estimated that 6% of electrical energy used in the U.S. "flows through" power supplies (not counting only the wall warts). The website where the report was published said in 2010 that despite the spread of SMPSs, "today's power supplies consume at least 2% of all U.S. electricity production. More efficient power supply designs could cut that usage in half". Since wasted electrical energy

2714-623: The termination of Motorola's clone contract, the discontinuation of the Motorola StarMax, and the long-favored Apple being demoted to "just another customer" mainly for PowerPC CPUs. Apple (and Jobs) did not want Motorola to limit the PowerPC CPU supply so as retaliation, Apple and IBM expelled Motorola from the AIM alliance and forced Motorola to stop producing any PowerPC CPUs, leaving IBM to make all future PowerPC CPUs. However, Motorola

2773-473: The time of its split, Motorola had three divisions: Motorola's handset division recorded a loss of $ 1.2 billion in the fourth quarter of 2007, while the company as a whole earned $ 100 million during that quarter. It lost several key executives to rivals, and the website TrustedReviews called the company's products repetitive and un-innovative. Motorola laid off 3,500 workers in January 2008, followed by

2832-693: The total efficiency of power supplies for small electronic equipment, the older mains-frequency linear transformer-based power supply was found in a 2002 report to have efficiencies from 20 to 75%, and have considerable energy loss even when powered up but not supplying power. Switched-mode power supplies (SMPSs) are much more efficient; a good design can be 80–90% efficient, and is also much smaller and lighter. In 2002 most external plug-in "wall wart" power adapters commonly used for low-power consumer electronics devices were of linear design, as well as supplies built into some equipment. External supplies are usually left plugged in even when not in use, and consume from

2891-452: The value of World War II military production contracts. Motorola went public in 1943, and became Motorola, Inc. in 1947. At that time Motorola's main business was producing and selling televisions and radios. The last plant was listed in Quincy, Illinois at 1400 North 30th Street where 1,200 employees made radio assemblies for both homes and automobiles. In 1969, Neil Armstrong spoke

2950-417: The weight, power supply units were externalized. When a laptop computer is operated while recharging, the integrated circuitry which controls the charging makes use of a power supply unit's remaining electrical current capacity. This allows supplying the device's components with power during usage while maintaining an uncompromised constant charging speed. The USB connector (and voltage) has emerged as

3009-530: The world in 1940, defense electronics, cellular infrastructure equipment, and mobile phone manufacturing. In the same year, the company built its research and development program with Dan Noble , a pioneer in FM radio and semiconductor technologies, who joined the company as director of research. The company produced the hand-held AM SCR-536 radio during World War II , which was vital to Allied communication. Motorola ranked 94th among United States corporations in

3068-683: The world's first commercial GPRS cellular network to BT Cellnet in the United Kingdom. Motorola also developed the world's first GPRS cell phone. In August 2000, Motorola acquired Printrak International Inc. for $ 160 million. In doing so, Motorola not only acquired computer aided dispatch and related software, but also acquired Automated fingerprint identification system software. With recent acquisitions from that year, Motorola reached its peak employment of 150,000 employees worldwide. Two years later, employment would be at 93,000 due to layoffs and spinoffs. In June 2005, Motorola overtook

3127-793: Was a pioneer in cellular telephones. Also known as the Personal Communication Sector (PCS) prior to 2004, it pioneered the "mobile phone" with the first truly mobile "brick phone" DynaTAC , "flip phone" with the MicroTAC as well as the "clam phone" with the StarTAC in the mid-1990s. It had staged a resurgence by the mid-2000s with the RAZR , but lost market share in the second half of that decade. Later it focused on smartphones using Google 's open-source Android mobile operating system. The first phone to use Android 2.0 "Eclair" ,

3186-413: Was added. Losses in the transformer and the linear regulator were considerable; efficiency was relatively low, and significant power dissipated as heat even when not driving a load. Early in the twenty-first century, switched-mode power supplies (SMPSs) became almost ubiquitous for this purpose due to their compact size and light weight relative to their power output ability. Mains voltage is rectified to

3245-572: Was also increasing the proportion of recycled materials used in its products. For example, the housings for the MOTO W233 Renew and MOTOCUBO A45 Eco mobile phones contained plastic from post-consumer recycled water cooler bottles. According to the company's information, all of Motorola's newly designed chargers met the current Energy Star requirements and exceed the requirements for standby/no-load modes by at least 67%. Battery eliminator An AC adapter or AC/DC adapter (also called

3304-1145: Was founded in 1928 as Galvin Manufacturing Corporation by brothers Paul and Joseph Galvin. The company changed its name to Motorola in 1947. After having lost $ 4.3 billion from 2007 to 2009, Motorola was split into two independent public companies, Motorola Mobility and Motorola Solutions , on January 4, 2011. The reorganization was structured with Motorola Solutions legally succeeding Motorola, Inc., and Motorola Mobility being spun off. Motorola designed and sold wireless network equipment such as cellular transmission base stations and signal amplifiers. Motorola's home and broadcast network products included set-top boxes , digital video recorders , and network equipment used to enable video broadcasting, computer telephony, and high-definition television . Its business and government customers consisted mainly of wireless voice and broadband systems (used to build private networks), and public safety communications systems like Astro and Dimetra . These businesses, except for set-top boxes and cable modems , became part of Motorola Solutions. Motorola's wireless telephone handset division

3363-549: Was later reinstated into the alliance in 1998. In 1998, Motorola was overtaken by Nokia as the world's biggest seller of mobile phone handsets. In 1999, Motorola separated a portion of its semiconductor business—the Semiconductor Components Group (SCG)-- and formed onsemi (then ON Semiconductor ), whose headquarters were located in Phoenix, Arizona . In June 2000, Motorola and Cisco supplied

3422-563: Was made by former Motorola employees. That same year, Motorola sold its television business to the Japan-based Matsushita – the parent company of Panasonic . In 1980, Motorola's next generation 32-bit microprocessor, the MC68000 , led the wave of technologies that spurred the computing revolution in 1984, powering devices from companies such as Apple , Commodore , Atari , Sun , and Hewlett-Packard . In September 1983,

3481-464: Was to have many similarities with existing satellite radio services (such as Sirius and XM Radio ) by offering live streams of commercial-free music content. Unlike satellite services, however, iRadio content would be downloaded via a broadband internet connection. However, iRadio was never commercially released. Greg Brown became Motorola's chief executive officer in 2008. In October 2008, Motorola agreed to sell its Biometrics business to Safran ,
