The RC-5 protocol was developed by Philips in the early 1980s as a semi-proprietary consumer IR remote control communication protocol for consumer electronics.It was subsequently adopted by most European manufacturers, as well as by many US manufacturers of specialty audio and video equipment.
The reorder tone is sometimes confused with the busy signal because they use the same frequencies and differ only in that the busy signal's beeping sounds have a slower cadence than those of the reorder tone.
The PGM-11 Redstone was the first large American ballistic missile. A short-range ballistic missile (SRBM), it was in active service with the United States Army in West Germany from June 1958 to June 1964 as part of NATO 's Cold War defense of Western Europe.
The x86 ISA, starting with the 8086, includes a series of special-purpose repeat instructions (REP(∅/E/Z/NE/NZ)) which are called "repeat string operation prefixes" and may only be applied to a small number of string instructions (INS, OUTS, MOVS, LODS, STOS, CMPS, SCAS). These instructions repeat an operation and decrement a counter until it ...
The received signal's strength and its dependence on orientation of the receiving coil yields approximate distance and directional information. Early models were called "speleophones"—for instance Bob Mackin's "Molefone". The Molefone is called "one of the first practical cave radios", though it is no longer manufactured. [2]
The command killall -9 has a similar, while dangerous effect, when executed e.g. in Linux; it does not let programs save unsaved data. It has other options, and with none, uses the safer SIGTERM signal. SIGPIPE The SIGPIPE signal is sent to a process when it attempts to write to a pipe without a process connected to the other end. SIGPOLL
The resulting signal has a higher bandwidth than the data, and therefore this is a method of spread-spectrum communication. When used only for the spread-spectrum property, this technique is called direct-sequence spread spectrum ; when used to distinguish several signals transmitted in the same channel at the same time and frequency, it is ...
Some repeaters also correct for distortion of the optical signal by converting it to an electrical signal, processing that electrical signal and then retransmitting an optical signal. Such repeaters are known as optical-electrical-optical (OEO) due to the conversion of the signal. These repeaters are also called regenerators for the same reason.
