SecuriLock. SecuriLock, also known as Passive Anti-Theft System ( PATS ), is an immobilizer technology that Ford began using select Ford as well as Lincoln, and Mercury models. Each key have a radio frequency transponder embedded in the plastic head with a unique electronic identification code.
The air traffic control radar beacon system ( ATCRBS) is a system used in air traffic control (ATC) to enhance surveillance radar monitoring and separation of air traffic. It consists of a rotating ground antenna and transponders in aircraft. The ground antenna sweeps a narrow vertical beam of microwaves around the airspace.
A communications satellite 's transponder is the series of interconnected units that form a communications channel between the receiving and the transmitting antennas. [1] It is mainly used in satellite communication to transfer the received signals. A transponder is typically composed of: an input band-limiting device (an input band-pass filter ),
