Abstract
A system includes a first and second circuit electromagnetically coupled to establish a contact-less transmission, for example, between a vehicle body and a removable seat of the vehicle body. The first circuit includes a first inductor and the second circuit includes a second inductor. In order to detect in the first circuit the status of one or more input signals of the second circuit, the second circuit includes a signal generating portion including a resistor and a capacitor that generates, a time-pulsed signal. The second circuit is adapted to set a value of at least one of the resistor and the capacitor based on a sensed parameter and sets a duty cycle of the time-pulsed signal based on a value of at least one of the resistor and the capacitor. The time-pulsed signal changes a load of the second circuit over time which can be detected in the first circuit.
