Abstract

An integrated circuit includes an on-chip gyrating circuit that generates a motion parameter based on motion of the IC. An RF transceiver generates an outbound RF signal from outbound data and that generates inbound data from an inbound RF signal. A processing module processes the motion parameter, generates the outbound data, and receives the inbound data.
