Pilots are normally required to apply the code, allocated by air traffic control, to that specific flight. Occasionally, countries may specify generic codes to be used in the absence of an allocated code. Such generic codes are specified in that country's Aeronautical Information Manual or Aeronautical Information Publication.
A remote starter is a radio controlled device, which is installed in a vehicle by the factory or an aftermarket installer to preheat or cool the vehicle before the owner gets into it. [1] Once activated, by pushing a button on a special key chain remote, it starts the vehicle automatically for a predetermined time.
The electric immobiliser/alarm system was invented by St. George Evans and Edward Birkenbuel and patented in 1919. [2] They developed a 3x3 grid of double-contact switches on a panel mounted inside the car so when the ignition switch was activated, current from the battery (or magneto) went to the spark plugs allowing the engine to start, or immobilizing the vehicle and sounding the horn.

Remote controls send a digital code word to the receiver. If the receiver determines the codeword is acceptable, then the receiver will actuate the relay, unlock the door, or open the barrier. Simple remote control systems use a fixed code word; the code word that opens the gate today will also open the gate tomorrow.
An early version of a car alarm for use as a theft deterrent was invented by an unknown prisoner from Denver in 1913. [1] This version was manually armed, and triggered when someone tried to crank the engine. A later alarm inspired by an early version of a remote starter was published in 1916. [2]
Each bit of the RC-5 code word contains 32 carrier pulses, and an equal duration of silence, so the bit time is 64×27.778 μs = 1.778 ms, and the 14 symbols (bits) of a complete RC-5 code word take 24.889 ms to transmit. The code word is repeated every 113.778 ms (4096 ÷ 36 kHz) as long as a key remains pressed.
Harmony 670, a 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 re
Code 1: A time critical event with response requiring lights and siren. This usually is a known and going fire or a rescue incident. Code 2: Unused within the Country Fire Authority. Code 3: Non-urgent event, such as a previously extinguished fire or community service cases (such as animal rescue or changing of smoke alarm batteries for the ...
