发明名称 Path finder/tracker system
摘要 A path finder/tracker system for assisting a person in finding the way back to a home base comprising a transmitter having a housing with electronic components therein, the electronic components including a emitter to emit a signal of a predetermined magnitude and frequency, the transmitter couplable to a power source with an on/off switch; and a receiver having a housing with electrical components including associated electrical components to receive the signal of the predetermined magnitude and frequency in the citizen band range tuned to that emitted by the transmitter, an antenna adapted to be retracted to a storage position within the receiver housing and extendable from the front edge thereof in a horizontal plane which is within the plane of the receiver, the receiver also including an array of lights across the front edge and adapted to sequentially light as a function of the strength of the signal received by the antenna whereby when the antenna is pointing directly at the transmitter, a predetermined light will be lit but when not pointed directly at the signal, another light will be lit, a panel to display the distance of the receiver from the transmitter.
