Jean-Maurice-Émile Baudot, French telegraph engineer and inventor of the first means of digital communication Baudot code, was one of the pioneers of telecommunications. He invented a multiplexed printing telegraph system that used his code and allowed multiple transmissions over a single line. The baud unit was named after him.
A telephone, or phone, is a telecommunications device that permits two or more users to conduct a conversation when they are too far apart to be heard directly. A telephone converts sound, typically and most efficiently the human voice, into electronic signals that are transmitted via cables and other communication channels to another telephone which reproduces the sound to the receiving user.
A programmable read-only memory (PROM) is a form of digital memory where the setting of each bit is locked by a fuse or antifuse. It is one type of ROM. The data in them is permanent and cannot be changed. PROMs are used in digital electronic devices to store permanent data, usually low level programs such as firmware or microcode. The key difference from a standard ROM is that the data is written into a ROM during manufacture, while with a PROM the data is programmed into them after manufacture. Thus, ROMs tend to be used only for large production runs with well-verified data, while PROMs are used to allow companies to test on a subset of the devices in an order before burning data into all of them.
Caller ID, also called calling line identification (CLID), Calling Line Identification (CLI), calling number delivery (CND), calling number identification (CNID), calling line identification presentation (CLIP), or call display, is a telephone service, available in analog and digital telephone systems, including VoIP, that transmits a caller's telephone number to the called party's telephone equipment when the call is being set up. The caller ID service may include the transmission of a name associated with the calling telephone number, in a service called CNAM.
Black & Decker Corporation was the name of an American manufacturer of power tools, accessories, hardware, home improvement products and technology based fastening systems headquartered in Towson, Maryland. On March 12, 2010, Black & Decker merged with Stanley Works to become Stanley Black & Decker. It remains as a wholly owned subsidiary of that company.
A DIP switch is a manual electric switch that is packaged with others in a group in a standard dual in-line package (DIP). The term may refer to each individual switch, or to the unit as a whole. This type of switch is designed to be used on a printed circuit board along with other electronic components and is commonly used to customize the behavior of an electronic device for specific situations.
Dr. Erna Schneider Hoover is an American mathematician notable for inventing a computerized telephone switching method which "revolutionized modern communication" according to several reports. It prevented system overloads by monitoring call center traffic and prioritizing tasks on phone switching systems to enable more robust service during peak calling times. At Bell Laboratories where she worked for over 32 years, Hoover was described as an important pioneer for women in the field of computer technology.
An electric stove or electric range is a stove with an integrated electrical heating device to cook and bake. Electric stoves became popular as replacements for solid-fuel stoves which required more labor to operate and maintain. Some modern stoves come in a unit with built-in extractor hoods.
Under United States law, a patent is a right granted to the inventor of a (1) process, machine, article of manufacture, or composition of matter, (2) that is new, useful, and non-obvious. A patent is the right to exclude others from using a new technology. Specifically, it is the right to exclude others from making, using, selling, offering for sale, importing, inducing others to infringe, and/or offering a product specially adapted for practice of the patent.
Standard Telephones and Cables Ltd was a British telephone, telegraph, radio, telecommunications, and related equipment R&D manufacturer. During its history, STC invented and developed several groundbreaking new technologies including pulse code modulation (PCM) and optical fibres.
Jean Calvignac is an IBM Fellow and was responsible for the architecture of PowerNP, an IBM network processor. He holds more than 220 patents.
Alcatel-Lucent S.A. was a French global telecommunications equipment company, headquartered in Boulogne-Billancourt, France. It was formed in 2006 by the merger of France-based Alcatel and U.S.-based Lucent, the latter being the successor of AT&T's Western Electric.
Multi-link trunking (MLT) is a link aggregation port trunking technology developed at Nortel in 1999. It allows grouping several physical Ethernet links into one logical Ethernet link to provide fault-tolerance and high-speed links between routers, switches, and servers. US patent 6731599, Van Hunter, Joseph Regan, Alfred Nothaft, Akhil Duggal; Regan, Joseph & Nothaft, Alfred et al., "Automatic Load Sharing-Trunking", issued 2004-05-04, assigned to Nortel Networks Limited and Avaya Holdings Limited
Amos Edward Joel Jr. was an American electrical engineer, known for several contributions and over seventy patents related to telecommunications switching systems.
Beam lead technology is a method of fabricating a semiconductor device. Its original application was to high-frequency silicon switching transistors and high-speed integrated circuits. It eliminated the labor-intensive wire-bonding process used for integrated circuits at the time and allowed automated assembly of semiconductor chips onto larger substrates to produce hybrid integrated circuits.
Server Technology, Inc. offers power distribution products and solutions for data centers, telecommunication equipment and remote administration. The company is headquartered in Reno, Nevada with offices in the United Kingdom, Germany, Hong Kong and India.
A telephone exchange is a telecommunications system used in the public switched telephone network or in large enterprises. An exchange consists of electronic components and in older systems also human operators that interconnect (switch) telephone subscriber lines or virtual circuits of digital systems to establish telephone calls between subscribers.
Victor Lyatkher is a professor, engineer, and inventor. He was educated in Moscow and Leningrad, and has developed and patented numerous processes and machines. These deal mainly with renewable energy sources such as tidal power, water turbines, and vertical axis wind turbines. He developed a new method to forecast long-term variations in the Caspian Sea level, and designed a new kind of low head turbine. Mr. Lyatkher has worked for over thirty years in the wind and hydro-power industry. He has received several prizes and awards for his accomplishments, including the Prize of the Council of Ministers of the USSR, the Award of the Indian Society of Earthquake Technology, and five medals of the All Union USSR Exhibition, gold, silver and bronze.
IPS is a screen technology for liquid-crystal displays (LCDs). It was designed to solve the main limitations of the twisted nematic field effect (TN) matrix LCDs which were prevalent in the late 1980s. These limitations included strong viewing angle dependence and low-quality color reproduction. In-plane switching involves arranging and switching the orientation of the molecules of the liquid crystal (LC) layer between the glass substrates. This is done, essentially, parallel to these glass plates.
A word processor (WP) is a computer program or device that provides for input, editing, formatting and output of text, often plus other features.
