James R. Biard
James Robert Biard (May 20, 1931 – September 23, 2022) was an American electrical engineer and inventor who held 73 U.S. patents. Some of his more significant patents include the first infrared light-emitting diode (LED), the optical isolator, Schottky clamped logic circuits, silicon Metal Oxide Semiconductor Read Only Memory (MOS ROM), a low bulk leakage current avalanche photodetector, and fiber-optic data links. In 1980, Biard became a member of the staff of Texas A&M University as an Adjunct Professor of Electrical Engineering. In 1991, he was elected as a member into the National Academy of Engineering for contributions to semiconductor light-emitting diodes and lasers, Schotky-clamped logic, and read-only memories. Early life Biard grew up and attended school in Paris, Texas. His father, James Christopher "Jimmy" Biard of Biardstown, worked as a farmer and a Dr. Pepper route salesman for the local Dr. Pepper company. Biard's mother, Mary Ruth Biard (née Bills), worked ...

Paris, Texas
Paris is a city and county seat of Lamar County, Texas, United States. Located in Northeast Texas at the western edge of the Piney Woods, the population of the city was 24,171 in 2020. History Present-day Lamar County was part of Red River County during the Republic of Texas. By 1840, population growth necessitated the organization of a new county. George Washington Wright, who had served in the Third Congress of the Republic of Texas as a representative from Red River County, was a major proponent of the new county. The Fifth Congress established the new county on December 17, 1840, and named it after Mirabeau B. Lamar, who was the first Vice President and the second President of the Republic of Texas. Lamar County was one of the 18 Texas counties that voted against secession on February 23, 1861. In 1877, 1896, and 1916, major fires in the city forced considerable rebuilding. The 1916 fire destroyed almost half the town and caused an estimated $11 million in property ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
Tau Beta Pi
The Tau Beta Pi Association (commonly Tau Beta Pi, , or TBP) is the oldest engineering honor society and the second oldest collegiate honor society in the United States. It honors engineering students in American universities who have shown a history of academic achievement as well as a commitment to personal and professional integrity. Specifically, the association was founded "to mark in a fitting manner those who have conferred honor upon their Alma Mater by distinguished scholarship and exemplary character as students in engineering, or by their attainments as alumni in the field of engineering, and to foster a spirit of liberal culture in engineering colleges". History When academic honor society Phi Beta Kappa sought to restrict its membership to students of the liberal arts in the late 19th century, Edward H. Williams Jr., a member of Phi Beta Kappa and head of the mining department at Lehigh University, formulated the idea of an honor society for those studying technic ...

Varactor Diode
In electronics, a varicap diode, varactor diode, variable capacitance diode, variable reactance diode or tuning diode is a type of diode designed to exploit the voltage-dependent capacitance of a reverse-biased p–n junction. Applications Varactors are used as voltage-controlled capacitors. They are commonly used in voltage-controlled oscillators, parametric amplifiers, and frequency multipliers. Voltage-controlled oscillators have many applications such as frequency modulation for FM transmitters and phase-locked loops. Phase-locked loops are used for the frequency synthesizers that tune many radios, television sets, and cellular telephones. The varicap was developed by the Pacific Semiconductor subsidiary of the Ramo Wooldridge Corporation who received a patent for the device in June 1961. The device name was also trademarked as the "Varicap" by TRW Semiconductors, the successor to Pacific Semiconductors, in October 1967. This helps explain the different names for the dev ...

SNX100
Sorting nexin-1 is a protein that in humans is encoded by the SNX1 gene. The protein encoded by this gene is a sorting nexin. SNX1 is a component of the retromer complex. Function This gene encodes a member of the sorting nexin family. Members of this family contain a phox ( PX) domain, which is a phosphoinositide binding domain, and are involved in intracellular trafficking. This endosomal protein regulates the cell-surface expression of epidermal growth factor receptor. This protein also has a role in sorting protease-activated receptor-1 from early endosomes to lysosome A lysosome () is a membrane-bound organelle found in many animal cells. They are spherical vesicles that contain hydrolytic enzymes that can break down many kinds of biomolecules. A lysosome has a specific composition, of both its membrane prot ...s. This protein may form oligomeric complexes with other family members. References Further reading * * * * * * * * * * * * * * * * * * * External lin ...

Integrated Circuit
An integrated circuit or monolithic integrated circuit (also referred to as an IC, a chip, or a microchip) is a set of electronic circuits on one small flat piece (or "chip") of semiconductor material, usually silicon. Large numbers of tiny MOSFETs (metal–oxide–semiconductor field-effect transistors) integrate into a small chip. This results in circuits that are orders of magnitude smaller, faster, and less expensive than those constructed of discrete electronic components. The IC's mass production capability, reliability, and building-block approach to integrated circuit design has ensured the rapid adoption of standardized ICs in place of designs using discrete transistors. ICs are now used in virtually all electronic equipment and have revolutionized the world of electronics. Computers, mobile phones and other home appliances are now inextricable parts of the structure of modern societies, made possible by the small size and low cost of ICs such as modern computer ...

Jack Kilby
Jack St. Clair Kilby (November 8, 1923 – June 20, 2005) was an American electrical engineer who took part (along with Robert Noyce of Fairchild) in the realization of the first integrated circuit while working at Texas Instruments (TI) in 1958. He was awarded the Nobel Prize in Physics on December 10, 2000. Kilby was also the co-inventor of the handheld calculator and the thermal printer, for which he had the patents. He also had patents for seven other inventions. Early life Kilby was born in 1923 in Jefferson City, Missouri to Hubert and Vina Freitag Kilby. Both parents had Bachelor of Science degrees from the University of Illinois. His father was a manager at a local utility company. Kilby grew up and attended school in Great Bend, Kansas, graduating from the Great Bend High School. (Road signs at the entrances to the town commemorate his time there, and the Commons Area at Great Bend High School has been named The Jack Kilby Commons Area.) Kilby received his Bachel ...
