Abstract
A communication system, comprising a pendant and a base (comprising a transmitter, a receiver, and a wireless power transmitter) and a pendant (comprising a transmitter, a receiver, and a wireless power receiver configured to wirelessly receive electrical energy from the wireless power transmitter). The transmitters, the receivers, the wireless power receiver, and the wireless power transmitter (at least) are sealed. The communication system is configured affect actions and operations in equipment based on conjectures of whether the pendant is in close proximity or medium proximity to the base by analyzing a power quantity that the wireless power receiver is receiving from the wireless power transmitter, the strength with which a signal emitted from a transmitters is received by a receiver, and/or comparing an extent to which motion detected by a motion detector in the base corresponds to motion detected by a motion detector in the pendant.
