Telecommunications relay service A telecommunications relay service, also known as TRS, relay service, or IP-relay, or Web-based relay service, is an operator service that allows people who are deaf, hard of hearing, deafblind, or have a speech disorder to place calls to standard telephone users via a keyboard or assistive device. Originally, relay services were designed to be connected through a TDD, teletypewriter (TTY) or other assistive telephone device. Services gradually have expanded to include almost any real-time text capable technology such as a personal computer, laptop, mobile phone, PDA, and many other devices. The first TTY was invented by deaf scientist Robert Weitbrecht in 1964. The first relay service was established in 1974 by Converse Communications of Connecticut.

George Ashley Campbell George Ashley Campbell (November 27, 1870 – November 10, 1954) was an American engineer. He was pioneer in developing and applying quantitative mathematical methods to the problems of long-distance telegraphy and telephony. His most important contributions were to the theory and implementation of the use of loading coils and the first wave filters designed to what was to become known as the image method. Both these areas of work resulted in important economic advantages for the American Telephone and Telegraph Company (AT&T).

Thomas Wright Hill Thomas Wright Hill (24 April 1763 in Kidderminster – 13 June 1851 in Tottenham) was a mathematician and schoolmaster. He is credited as inventing the single transferable vote in 1819. His son, Rowland Hill, famous as the originator of the modern postal system, introduced STV in 1840 into the world's first public election, for the Adelaide City Council, in which the principle of proportional representation was applied.

Nordic Mobile Telephone NMT ("Nordisk MobilTelefoni" or "Nordiska MobilTelefoni-gruppen", "Nordic Mobile Telephony" in English) is the first fully automatic cellular phone system. It was specified by Nordic telecommunications administrations (PTTs) and opened for service on 1 October 1981 as a response to the increasing congestion and heavy requirements of the manual mobile phone networks: ARP (150 MHz) in Finland, MTD (450 MHz) in Sweden and Denmark, and OLT in Norway.

J. B. Fenby Joseph Beverley Fenby was an inventor in St Johns, Worcester, England. He was granted a patent on 13 January 1863 (Brit. pat. 101) for an unsuccessful device called either the “Electro-Magnetic Phonoscope” or the “Electro-Magnetic Phonograph”. If the latter name is correct, it could make Fenby the first to have coined the word "phonograph", long before Thomas Edison did so for his very different invention. Fenby's concept detailed a system that would record a sequence of piano or organ keyboard strokes onto paper tape. Although no model or workable device was ever made, it could be seen as a link to the concept of punched paper for player piano rolls (1880s), as well as Herman Hollerith's punch card tabulator (used in the 1890 census), a distant precursor to the modern computer.

Thomas Edison Thomas Alva Edison (February 11, 1847October 18, 1931) was an American inventor and businessman, who has been described as America's greatest inventor. He developed many devices that greatly influenced life around the world, including the phonograph, the motion picture camera, and the long-lasting, practical electric light bulb. Dubbed "The Wizard of Menlo Park", he was one of the first inventors to apply the principles of mass production and large-scale teamwork to the process of invention, and because of that, he is often credited with the creation of the first industrial research laboratory.

Telegraph sounder A telegraph sounder is an antique electromechanical device used as a receiver on electrical telegraph lines during the 19th century. It was invented by Alfred Vail after 1850 to replace the previous receiving device, the cumbersome Morse register and was the first practical application of the electromagnet. When a telegraph message comes in it produces an audible "clicking" sound representing the "dots" and "dashes" of Morse code. A telegraph operator would translate the sounds into characters representing the telegraph message.
