Abstract:
1. An electrical unit having: a wireless communications port; a transceiver coupled to the port; and control circuitry coupled to the transceiver, the control circuitry and transceiver have, at least, an inactive mode interrupted by an intermittent, limited duration higher power active mode, the control circuitry including circuitry to monitor the port for receipt of a wireless synchronization signal, and responsive thereto to establish a predetermined time offset from the wireless synchronizing signal and only a receiver portion of the transceiver to enter the active mode at a time interval, corresponding to the offset, prior to receipt of subsequent wireless synchronizing signals and to receive other incoming signals with the control circuitry responding to an incoming signal requesting information by causing a transmitter portion of the transceiver to enter the active mode and transmitting requested information using at least one byte of information having a plurality of bits via the transceiver and where the control circuitry simultaneously monitors wireless signals received from the transceiver and upon detecting a received wireless signal in the absence of a transmitted wireless signal determines that a higher priority message is being received and responsive to that determination terminates the transmission before completion of the byte, said control circuitry including executable instructions for at least receiving data using a different protocol than a protocol exhibited by the synchronizing signal and executable instructions that sense and decode multiple data signals received from multiple sources substantially simultaneously and where the sense and decode process comprises bit arbitration.
