摘要： A movable or removable seat for a motor vehicle is disclosed which preferably takes the form of a removable vehicle seat (1). The removable seat incorporates a first inductor (17) which forms part of an inductive coupling between the removable seat and a second inductor (21) which is mounted on the motor vehicle. The first inductor forms part of a resonant circuit which incorporates at least one capacitor. The resonant frequency of the resonant circuit is variable in response to a sensed parameter such as, for example, the position of a head-rest of the seat, the inclination of the back-rest of the seat and such like. A central unit (23) generates a square wave which excites the resonant circuit. A signal is transmitted from the resonant circuit to the central unit (23) which analyses the resonant frequency of the resonant circuit.

摘要： A drive arrangement (1) for driving a vehicle safety device (18) incorporates an input (2) which is connected to an output (9) of an electronic control unit (5). The output (9) of the electronic control unit (5) is an output which is operable to provide a firing signal to activate a pyrotechnic squib in a safety device, such as an airbag module. The drive arrangement (1) incorporates first and second analysers (14, 15) which perform first and second algorithms on a firing signal provided by the electronic control unit (5) to determine that the firing signal would have activated a pyrotechnic squib. The drive arrangement (1) provides an output signal to a safety device (18) if both the first and second analysers (14, 15) determine that the firing signal would have activated the pyrotechnic squib.
