ABSTRACT:
The Incident Location Reporting Security System pertains to a device that is capable of determining instantaneously, via the use of pulse-width coded modulation, the location of incidences such as burglary, robbery and fire. Detailed multi-point monitoring can be carried out in such varied sites in a multistory buildings, residential neighborhoods, museums or individuals. The concept allows for generation and reading of billions of different codes through the simplistic design of a coded receiver wherein codes are read instead of matched. In achieving this capability, a base number is created by multiplying the plurality of positions of a switch times the number of switches and thereafter pulsing a transmitter a number of times to generate a code in which the base number is raised to the power of the number of times it is pulsed. Each transmitter is assigned a specific coded number and a single receiver rapidly processes and identifies any coded number received. In order to identify the position of an individual immediately at the time an alarm is sounded, triangulation is used.
