Abstract
A redundant inductive sensor system includes at least two interface circuits, each associated with a respective transmitting coil that is electromagnetically coupled to one or more receiving coils. The first interface circuit transmits during a first transmitting interval and the second interface circuit transmits during a second transmitting interval that does not overlap with the first transmitting interval. The first interface circuit receives the second signal during a first listening interval of the first interface circuit encompassing the second transmitting interval and the second interface circuit receives the first signal during a second listening interval of the second interface circuit encompassing the first transmitting interval. By listening to transmissions from transmitting coils other than an associated transmitting coil, interface circuits can detect errors in other interface circuits.
