Sharp 14-inch thin-film-transistor liquid-crystal display (TFT-LCD) for TV, which has ushered in TFT LCD industry +Sharp demonstrated a fourteen-inch TFT-LCD for TV in 1988 when the display size of the mass-produced TFT-LCD was three inches. The high display quality in Cathode Ray Tube size convinced other electronic companies to join the infant TFT-LCD industry aimed at emerging full-color portable PCs. Two decades later, TFT-LCDs replaced CRTs, making the vision of RCA's LCD group in the 1960s a reality.
Sonar, 100th birthday of Paul Langevin Invention 1917-2017 +In France in 1917, Paul Langevin, a French physicist, produced transceivers using the piezo-electric effect of quartz crystals, and designed a submarine detector based on the effect, resulting in an improved method for submarine ultrasonic echo detection, namely sonar, obtaining 4000 meter echo soundings from the cable ship CHARENTE in the Bay of Biscay. Echo sounding based on piezoelectric effect became a central topic for new researchers, academic physicists and electrical engineers, with many applications like medical echography and diverse acoustic sensors. Langevin’s extensive knowledge of and practice with piezoelectricity beneficiating from research of Pierre Curie, which allowed him to manipulate the crystals and contrive the novel ultrasonic design required
Special Citation Computer History Museum +The Computer History Museum's mission is to preserve and present for posterity the artifacts and stories of the Information Age. Founded in 1979 in Massachusetts, it completed a move to Silicon Valley in 1999. The museum houses the world's largest collection of computers and related software, documents, and visual media. Public exhibits celebrate the rich history of computing, aided by a speaker series, education activities, historical restorations, and research programs.

TPC-1 System +The first transpacific undersea coaxial telephone cable linking Japan, Hawaii, and the U.S. mainland was completed in 1964. President Lyndon B. Johnson and Prime Minister Hayato Ikeda inaugurated this communications link on 19 June 1964. This joint project involving American Telephone and Telegraph, Hawaiian Telephone Company, and Kokusai Denshin Denwa improved global communication and contributed to deep water submarine cable technologies.
The 20 inch Diameter Photomultiplier Tubes +Hamamatsu Photonics K.K. began developing 20-inch diameter photomultiplier tubes at Toyooka Factory in 1979 for a 3000-ton water-filled Cherenkov particle detector, Kamiokande-II, in response to a request by Professor Masatoshi Koshiba. 1071 PMTs on it collected photons induced in the water by the particles falling on it. Kamiokande-II detected a neutrino burst in the Supernova SN1987A in 1987, earning Professor Koshiba a Nobel Prize in 2002.
The Abacus +The abacus, which was already used in China by 570 C.E., is one of the earliest calculating mechanisms known. A typical Chinese abacus is constructed as a bamboo frame with beads sliding on rods. An abacus helps people keep track of numbers as they calculate, and it was an early step towards the design of automatic calculators.
The Birthplace of Silicon Valley +At this location, 391 San Antonio Road, the Shockley Semiconductor Laboratory manufactured the first silicon devices in what became known as Silicon Valley. Some of the talented scientists and engineers initially employed there left to found their own companies, leading to the birth of the silicon electronics industry in the region. Hundreds of firms in electronics and computing can trace their origins back to Shockley Semiconductor.
The First Breaking of Enigma Code by the Team of Polish Cipher Bureau, 1932-39 +Polish Cipher Bureau mathematicians Marian Rejewski, Jerzy Różycki and Henryk Zygalski broke the German Enigma cipher machine codes. Working with engineers from the AVA Radio Manufacturing Company, they built the ‘bomba’ – the first cryptanalytic machine to break Enigma codes. Their work was a foundation of British code breaking efforts which, with later American assistance, helped end World War II.
The High Definition Television System, 1964-1989 +NHK (Japan Broadcasting Corporation) developed high-definition television (HDTV), a high-resolution and wide-screen television system designed to convey a strong sense of reality to viewers. Beginning in 1964, wide-ranging research, from psychophysical experiments to system development, and in 1989 the world's first HDTV broadcasting via satellite, opened a new era in broadcasting. Since 1989, HDTV has spread widely throughout the world.
The MU (Middle and Upper atmosphere) radar, 1984 +In 1984, Kyoto University built the MU (Middle and Upper atmosphere) radar as the first large-scale MST (Mesosphere, Stratosphere, and Troposphere) radar with a two-dimensional active phased array antenna system, with the collaboration of Mitsubishi Electric Corporation. The MU radar enabled continuous and flexible observation of the atmosphere, and has contributed to the progress of atmospheric science and radar engineering.
The first human rescue and life saving enabled by space technology +DRAFT In commemoration of the first time that a human life was saved by the use of information obtained by satellite. On September XX 1982 the pilot of a light aircraft which had crashed in the mountains of British Columbia was rescued using location data obtained by use of a satellite.
Trans-Atlantic Telephone Fiber-optic Submarine Cable (TAT-8) - 1988 +TAT-8, the first fiber-optic cable to cross an ocean, entered service on 14 December 1988. AT&T, British Telecom and France Telecom led the consortium that built TAT-8, which covered a seabed distance of 5846 Km. between North America and Europe. AT&T Bell Laboratories developed the foundational technologies: 1.3 micron fiber, cable, splicing, laser detector, and 280 Mbps repeater for 40,000 telephone-call capacity, and led the integration at Freehold, NJ.

U

Unidirectional Microphone +In 1939, Shure Incorporated introduced the Unidyne microphone. Using the Uniphase acoustical system, the patented Unidyne was the first microphone to provide directional characteristics using a single dynamic element. This breakthrough offered lower cost, greater reliability and improved performance for communication and public address systems. Shure Unidyne microphones are still manufactured and used worldwide in numerous audio applications.

V

Virginia Smith HVDC Converter Station with Integrated AC Voltage Control Function +Built by Siemens and operated since 1987 by the Western Area Power Administration (US DOE), the 200 MW HVDC Virginia Smith Converter Station near Sidney, Nebraska, connects the eastern and western U.S. grids. Its core technology is an all solid-state converter with integrated steady-state, dynamic, and transient voltage control up to its full rating. The station was an important advance in HVDC technology and cost-effectiveness.

W

Weston Meters +Edward Weston’s 334 patents made revolutionary contributions to the use and measurement of electricity. Among his contributions, he replaced batteries with dynamos in the electroplating industry, improved 100-fold the lifetime of the incandescent lamp filament, invented the use of laminated cores for generators, and developed a practical precision, direct reading, portable current meter which became the basis for the voltmeter, ammeter and watt meter.

Z

Zenit three-coordinate L-band pulsed radar, 1938 +The 1938 Zenit radar test at the Laboratory of Electromagnetic Oscillations of the Ukrainian Institute of Physics and Technology was a major advance in the development of radar. Designed by Abram Slutskin, Alexander Usikov and Semion Braude, microwave scientists and magnetron pioneers, Zenit established the practicality of combining the pulsed method and a shorter wave band for determining precisely all three coordinates of airborne targets.
