Abstract:
1. A detection system for detecting a vehicle operably coupled to and pulled by a cable extending between at least two stations, said cable coupled to and shiftable by a control/command system for selective transportation of said vehicle between said at least two stations, the detection system comprising: a beacon carried by the vehicle, said beacon configured for selectively emitting a beacon signal; a receiving antenna placed at each of a respective one of said at least two stations, each of said receiving antennas configured for receiving the beacon signal emitted by said beacon when said vehicle is within a predetermined proximal distance of each respective one of said stations; and a retractable element operatively coupled to said vehicle, said retractable element shiftable between an extended first position protruding from the vehicle and a retracted second position, said beacon emitting said beacon signal only when the retractable element is in said extended first position; wherein said control/command system is constructed to halt said selective transportation of said vehicle in response to reception of said beacon signal within said predetermined proximal distance of any one of said stations, wherein said predetermined proximal distance is sufficiently large to enable said selective transportation of said vehicle to be halted prior to entry of said vehicle into one of said stations upon the receiving antenna placed at the one of said stations receiving said beacon signal.
