Universal Remote
A universal remote is a remote control that can be programmed to operate various brands of one or more types of consumer electronics devices. Low-end universal remotes can only control a set number of devices determined by their manufacturer, while mid- and high-end universal remotes allow the user to program in new control codes to the remote. Many remotes sold with various electronics include universal remote capabilities for other types of devices, which allows the remote to control other devices beyond the device it came with. For example, a VCR remote may be programmed to operate various brands of televisions. History On May 30, 1985, Philips introduced the first universal remote (U.S. Pat. #4774511) under the Magnavox brand name. In 1985, Robin Rumbolt, William "Russ" McIntyre, and Larry Goodson with North American Philips Consumer Electronics (Magnavox, Sylvania, and Philco) developed the first universal remote control. In 1987, the first programmable universal remote ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

Satellite
A satellite or an artificial satellite is an object, typically a spacecraft, placed into orbit around a celestial body. They have a variety of uses, including communication relay, weather forecasting, navigation ( GPS), broadcasting, scientific research, and Earth observation. Additional military uses are reconnaissance, early warning, signals intelligence and, potentially, weapon delivery. Other satellites include the final rocket stages that place satellites in orbit and formerly useful satellites that later become defunct. Except for passive satellites, most satellites have an electricity generation system for equipment on board, such as solar panels or radioisotope thermoelectric generators (RTGs). Most satellites also have a method of communication to ground stations, called transponders. Many satellites use a standardized bus to save cost and work, the most popular of which are small CubeSats. Similar satellites can work together as groups, forming constellatio ...

Flash Memory
Flash memory is an Integrated circuit, electronic Non-volatile memory, non-volatile computer memory storage medium that can be electrically erased and reprogrammed. The two main types of flash memory, NOR flash and NAND flash, are named for the NOR gate, NOR and NAND gate, NAND logic gates. Both use the same cell design, consisting of floating-gate MOSFETs. They differ at the circuit level, depending on whether the state of the bit line or word lines is pulled high or low; in NAND flash, the relationship between the bit line and the word lines resembles a NAND gate; in NOR flash, it resembles a NOR gate. Flash memory, a type of floating-gate memory, was invented by Fujio Masuoka at Toshiba in 1980 and is based on EEPROM technology. Toshiba began marketing flash memory in 1987. EPROMs had to be erased completely before they could be rewritten. NAND flash memory, however, may be erased, written, and read in blocks (or pages), which generally are much smaller than the entire devi ...

Telecommunications
Telecommunication, often used in its plural form or abbreviated as telecom, is the transmission of information over a distance using electronic means, typically through cables, radio waves, or other communication technologies. These means of transmission may be divided into communication channels for multiplexing, allowing for a single medium to transmit several concurrent Session (computer science), communication sessions. Long-distance technologies invented during the 20th and 21st centuries generally use electric power, and include the electrical telegraph, telegraph, telephone, television, and radio. Early telecommunication networks used metal wires as the medium for transmitting signals. These networks were used for telegraphy and telephony for many decades. In the first decade of the 20th century, a revolution in wireless communication began with breakthroughs including those made in radio communications by Guglielmo Marconi, who won the 1909 Nobel Prize in Physics.

Global Positioning System
The Global Positioning System (GPS) is a satellite-based hyperbolic navigation system owned by the United States Space Force and operated by Mission Delta 31. It is one of the global navigation satellite systems (GNSS) that provide geolocation and time information to a GPS receiver anywhere on or near the Earth where there is an unobstructed line of sight to four or more GPS satellites. It does not require the user to transmit any data, and operates independently of any telephone or Internet reception, though these technologies can enhance the usefulness of the GPS positioning information. It provides critical positioning capabilities to military, civil, and commercial users around the world. Although the United States government created, controls, and maintains the GPS system, it is freely accessible to anyone with a GPS receiver. Overview The GPS project was started by the U.S. Department of Defense in 1973. The first prototype spacecraft was launched in 1978 an ...

K–12
K–12, from kindergarten to 12th grade, is an English language expression that indicates the range of years of publicly supported primary and secondary education found in the United States and Canada, which is similar to publicly supported school grades before tertiary education in several other countries, such as Afghanistan, Armenia, Australia, China, Ecuador, Egypt, India, Iran, the Philippines, South Korea, and Turkey. K–12 refers to the American system which affords authority to local intersectional "districts" which may be specific to a municipality, county, or several regions, depending on population and proximity. History Australia In Australia, P–12 is sometimes used in place of K–12, particularly in Queensland, where it is used as an official term in the curriculum framework. P–12 schools serve children for the thirteen years from prep until Year 12, without including the separate kindergarten component. Canada In Canada (Nova Scotia), P–12 is used commonl ...

CL 9
CL 9 was a company that developed a universal TV remote control. It was started by Steve Wozniak, co-founder of Apple Inc. and designer of the Apple I and Apple II personal computers. CL 9 was in business for three years, from 1985 to 1988, launching the 6502-based CL 9 CORE remote control in 1987, which Wozniak calls the first programmable universal remote control. History Wozniak was working at Apple Inc., Apple Computer as an Apple II engineer. He enjoyed his work, but he believed he was not making a valuable contribution because of his role as an Apple spokesperson and because it had become a big company. At the same time, Wozniak had a state-of-the-art home theater in the Santa Cruz Mountains, made of myriad devices, each from different manufacturers and with a unique remote control. The frustrating complexity inspired him to invent what is now known as a universal remote. He got some friends interested, and started a new company to build the device. Wozniak decided to ...
