Electronic warning apparatus
First Claim
1. A warning system for sensing conditions at a remote source comprising a transmitter located in the region of said remote source for transmitting a coded signal in response to an abnormal condition sensed at said remote source, said coded signal comprising information of the abnormal condition sensed and the location of said transmitter, and a monitor for receiving said transmitted coded signal and indicating said abnormal condition sensed and the location of said transmitter;
- said transmitter comprising a power supply for said transmitter, sensing means responsive to an abnormal condition at said remote source, coding means comprising a silicon controlled rectifier gate array connected to said power supply and said sensing means for activating said transmitter when said sensing means detects an abnormal condition, and comprising means for generating a coded signal in response to said activation of said transmitter when said sensing means detects an abnormal condition, and means connected to said coding means for transmitting said generated coded signal;
said monitor comprising a power supply for said monitor, means for receiving said transmitted coded signal, means connected to said detecting means for decoding said signal received, and means connected to said decoding means for indicating said abnormal condition sensed by said sensing means of said transmitter and comprising matrix means for indicating said location of said transmitter.
