Abstract
A locator system for determining when an object has entered a predetermined monitoring area. The locator system includes a central base unit and at least one remote unit. The central base unit includes a transmitter for transmitting a monitoring signal within the predetermined area, an alarm signal generator and a receiver. Each of the at least one remote units includes a receiver for receiving the monitoring signal when positioned within the monitoring area and a device for generating and transmitting a response signal for receipt by the receiver in the central base unit. The central base unit is caused to generate an alarm signal upon receipt of the response signal thereby alerting a person monitoring the central base unit that the at least one remote unit has entered the monitoring area. The central base unit may include a device for adjusting a strength of the monitoring signal and thereby adjust the size of the monitoring area. Alternatively, the remote unit may include a device for adjusting a strength of the response signal and thereby adjust the size of the monitoring area. When more than one remote unit is being monitored by the central base unit each of the remote units is identified by a respective identification code, the identification codes being stored within a processor of the central base unit, the identification code being transmitted by respective remote units with the response signal.
