Passive detection system for levitated vehicle or levitated vehicle system
First Claim
1. A passive detection system for a levitated vehicle, said system comprising:
- at least one track circuit including a detection loop having a cable with a first end, a length and a second end, said track circuit also including a transmitter electrically connected to the first end of the cable and adapted to source a signal to the detection loop, and a receiver electrically connected to the second end of the cable and adapted to sense said signal from the detection loop;
an inductor core including two openings adapted to receive the length of the cable and two openings adapted to avoid the first and second ends of said cable, said inductor core adapted to change the sensed signal of the receiver of said track circuit in order to detect a presence of said levitated vehicle at the detection loop; and
a member adapted to support said inductor core from said levitated vehicle.

Abstract
A passive detection system for a levitated vehicle includes track circuits. Each track circuit includes a detection loop having a cable with a first end, a length and a second end. The track circuit also includes a transmitter electrically connected to the first end of the cable and adapted to source a current to the detection loop, and a receiver electrically connected to the second end of the cable and adapted to sense the current from the detection loop. An inductor core includes two openings adapted to receive the length of the cable and two openings adapted to avoid the first and second ends of the cable. The inductor core is adapted to change the sensed current of the receiver, in order to detect a presence of the levitated vehicle at the detection loop. A member is adapted to support the inductor core from the vehicle.
