Abstract
A system for detecting the occupancy status of a seat is described. One embodiment comprises at least one transmitter of a high-frequency electromagnetic signal and at least one receiver that receives the electromagnetic signal. The receiver determines the intensity of the received signal compared to at least one threshold value, which indicates whether an occupant or part of an occupant is located between a transmitting antenna and a receiving antenna. In a specific embodiment, a single transmitter and a plurality of receivers are used to determine information about the occupancy status and the position of the occupant within the seat, and the information is output to a triggering system for use in the deployment of an occupant restraint system.
