Simple remote control systems use a fixed code word; the code word that opens the gate today will also open the gate tomorrow. An attacker with an appropriate receiver could discover the code word and use it to gain access sometime later. More sophisticated remote control systems use a rolling code (or hopping code) that changes for every use.
Antenna gain-to-noise-temperature ( G/T) is a figure of merit in the characterization of antenna performance, where G is the antenna gain in decibels at the receive frequency, and T is the equivalent noise temperature of the receiving system in kelvins. The receiving system noise temperature is the summation of the antenna noise temperature and ...
A JP1 Remote Control. A JP1 remote is a type of universal remote, usually with a six-pin interface connector labeled "JP1" in the battery compartment, manufactured by Universal Electronics Inc. The JP1 interface allows the remote to be reprogrammed, adding new code lists and functions. Home theater hobbyists use JP1 to avoid obsolescence .
Remote broadcast. In broadcast engineering, a remote broadcast (usually just called a remote or a live remote, or in news parlance, a live shot) is broadcasting done from a location away from a formal television or radio studio and is considered an electronic field production (EFP). A remote pickup unit (RPU) is usually used to transmit the ...
Remote terminal unit. A remote terminal unit ( RTU) is a microprocessor -controlled electronic device that interfaces objects in the physical world to a distributed control system or SCADA (supervisory control and data acquisition) system by transmitting telemetry data to a master system, and by using messages from the master supervisory system ...
A telemeter is a physical device used in telemetry. It consists of a sensor, a transmission path, and a display, recording, or control device. Electronic devices are widely used in telemetry and can be wireless or hard-wired, analog or digital. Other technologies are also possible, such as mechanical, hydraulic and optical.
The Zenith Flash-Matic was the first wireless remote control, invented by Eugene Polley in 1955. It had only one button that was used to power on and off, channel up, channel down, and mute. The Flash-matic's phototechnology was a significant innovation in television and allowed for wireless signal transfer previously exclusive to radio. [ 1][ 2]
The AN/ALR-67 countermeasures warning and control system is the standard threat warning system for tactical aircraft and was specifically designed for the A-6E/SWIP, AV-8B, F-14B, F-14D and F/A-18. The system detects, identifies and displays radars and radar-guided weapon systems in the C to J frequency range (about 0.5 to 20 GHz).
