Abstract:
     A system for communicating with plural remote transmitters in which the transmitters send messages without a common synchronization source or polling by a controlling receiver. In one embodiment, the system uses the time position of frequency chirp signals to encode the identity and/or other information sent from the receiver. The system may use relatively low cost transmitters because the transmitters do not need to have a message or clocking signal receiving capability and the internal clocking signal source within the transmitter may be a relatively inexpensive device or circuit.
