CalculatorA calculator is typically a portable electronic device used to perform calculations, ranging from basic arithmetic to complex mathematics. The first solid-state electronic calculator was created in the early 1960s. Pocket-sized devices became available in the 1970s, especially after the Intel 4004, the first microprocessor, was developed by Intel for the Japanese calculator company Busicom.
Transistor radioA transistor radio is a small portable radio receiver that uses transistor-based circuitry. Previous portable radios used vacuum tubes, which were bulky, fragile, had a limited lifetime, consumed excessive power and required large, heavy batteries.
MicrocontrollerA microcontroller (MC, uC, or μC) or microcontroller unit (MCU) is a small computer on a single integrated circuit. A microcontroller contains one or more processor cores along with memory and programmable input/output peripherals. Program memory in the form of NOR flash, OTP ROM, or ferroelectric RAM is also often included on the chip, as well as a small amount of RAM.
Digital light processingDigital light processing (DLP) is a set of chipsets based on optical micro-electro-mechanical technology that uses a digital micromirror device. It was originally developed in 1987 by Larry Hornbeck of Texas Instruments. While the DLP imaging device was invented by Texas Instruments, the first DLP-based projector was introduced by Digital Projection Ltd in 1997. Digital Projection and Texas Instruments were both awarded Emmy Awards in 1998 for the DLP projector technology.
Embedded systemAn embedded system is a specialized computer system—a combination of a computer processor, computer memory, and input/outputperipheral devices—that has a dedicated function within a larger mechanical or electronic system. It is embedded as part of a complete device, often including electrical or electronic hardware and mechanical parts. Embedded systems control many devices in common use.
SemiconductorA semiconductor is a material with electrical conductivity between that of a conductor and an insulator. Its conductivity can be modified by adding impurities ("doping") to its crystal structure. When two regions with different doping levels are present in the same crystal, they form a semiconductor junction.
DallasDallas is a city in the U.S. state of Texas. Located in northern Texas, it is the ninth-most populous city in the United States and third-most populous city in Texas, with a population of 1.3 million at the 2020 census. Along with the city of Fort Worth, Dallas anchors the Dallas–Fort Worth metroplex, the fourth-most populous metropolitan area in the U.S. and the most populous metropolitan area in Texas, at 8.5 million people.
TransistorA transistor is a semiconductor device used to amplify or switch electrical signals and power. It is one of the basic building blocks of modern electronics. It is composed of semiconductor material, usually with at least three terminals for connection to an electronic circuit. A voltage or current applied to one pair of the transistor's terminals controls the current through another pair of terminals.Linear integrated circuitA linear integrated circuit or analog chip is a set of miniature electronic analog circuits formed on a single piece of semiconductor material.
Multi-core processorA multi-core processor (MCP) is a microprocessor on a single integrated circuit (IC) with two or more separate central processing units (CPUs), called cores to emphasize their multiplicity (for example, dual-core or quad-core). Each core reads and executes program instructions, specifically ordinary CPU instructions (such as add, move data, and branch).
Geophysical ServiceGeophysical Service Inc. (often abbreviated GSI) was a Texas-based company founded by John Clarence Karcher and Eugene McDermott in 1930, for the purpose of using refraction and reflection seismology to explore for petroleum deposits. HistoryOn December 6, 1941, the company was purchased by Eugene McDermott, Cecil Howard Green, J. Erik Jonsson, and H.B. Peacock. During World War II, the company produced submarine detection devices.
SalesSales are commercial dealings in which a seller transfers ownership of products or provides services to a buyer in exchange for money or other agreed-upon consideration. The term may also refer to the quantity or monetary value of goods sold in a given targeted time period. The delivery of a service for a cost is also considered a sale. A period during which goods are sold for a reduced price may also be referred to as a "sale".*As an Amazon Associate I earn from qualifying purchases.
