Ten-codes, officially known as ten signals, are brevity codes used to represent common phrases in voice communication, particularly by law enforcement and in citizens band (CB) radio transmissions. The police version of ten-codes is officially known as the APCO Project 14 Aural Brevity Code. [1]
Radio control (often abbreviated to RC) is the use of control signals transmitted by radio to remotely operate a device. Examples of simple radio control systems are garage door openers and keyless entry systems for vehicles, in which a small handheld radio transmitter unlocks or opens doors.
X10 is a protocol for communication among electronic devices used for home automation ( domotics ). It primarily uses power line wiring for signaling and control, where the signals involve brief radio frequency bursts representing digital information. A wireless radio -based protocol transport is also defined.
Code 10: Request to clear frequency for broadcast of wanted/warrant information Code 12: Request to clear frequency for request for information on potential individual arrest warrant Code 20: Notify media (or media already on scene)
1:10 scale radio-controlled car (Saab Sonett II) A radio-controlled model (or RC model) is a model that is steerable with the use of radio control (RC). All types of model vehicles have had RC systems installed in them, including ground vehicles, boats, planes, helicopters and even submarines and scale railway locomotives.
A radio button or option button[citation needed] is a graphical control element that allows the user to choose only one of a predefined set of mutually exclusive options. [1] The singular property of a radio button makes it distinct from checkboxes, where the user can select and unselect any number of items.
R-S-T system. For other uses, see RST (disambiguation). S-Meter (ICOM IC-732 HF Transceiver) The R-S-T system is used by amateur radio operators, shortwave listeners, and other radio hobbyists to exchange information about the quality of a radio signal being received. The code is a three digit number, with one digit each for conveying an ...
In the United States, response codes are used to describe a mode of response for an emergency unit responding to a call. They generally vary but often have three basic tiers: Code 3: Respond to the call using lights and sirens. Code 2: Respond to the call with emergency lights, but without sirens. Alternatively, sirens may be used if necessary ...
Brevity codes are used in amateur radio, maritime, aviation and military communications. They are designed to convey complex information with a few words or codes. Some are classified from the public. List. ACP-131 Allied military brevity codes; ARRL Numbered Radiogram
The servo is controlled by three wires: ground, power, and control. The servo will move based on the pulses sent over the control wire, which set the angle of the actuator arm. The servo expects a pulse every 20 ms in order to gain correct information about the angle. The width of the servo pulse dictates the range of the servo's angular motion.
