Wireless signaling system
First Claim
1. A signaling system for indicating status information from one or more remote locations to a central location comprising:
- logic circuit means for generating periodic single frequency signals including synchronization signals and a plurality of time intervals for the insertion of data information therein, wherein each time interval bears a predetermined time relationship to said synchronization signal and corresponds to an assigned remote unit and wherein each time interval includes a plurality of discrete data intervals,at least one remote unit including means for providing status indicating data signals, said providing means coupled to said logic circuit means for the insertion of data during a predetermined data and time interval assigned the remote unit,a centrally located unit for receiving said data signals and including means for displaying one of a plurality of status conditions of said at least one remote location in response to said data signals.

Abstract
A wireless signaling between one or more remote locations and a central location includes a transmitter at each remote location and switches for providing signals indicating status information on each remote location. A logic circuit coupled to the switches and to the transmitter provide signals effecting transmission of a signal modulated to uniquely identify the remote location and the status represented by the switches. A receiver at the central location is coupled to a second logic circuit for decoding the signals received from the transmitter and is coupled to indicators for providing an indication of the status at the first location.
