ABSTRACT:
A system is provided for automatic identification of objects, such as rail cars and the like, utilizing two transponders, each attached to the rail car by a bracket. The bracket, which is welded along its ends to the rail car, has a lower planar surface which is placed against the side of the rail car when the bracket is welded thereto. A bottom planar surface of the transponder mates with an upper planar surface of the bracket, thus ensuring a good conduction heat flow path to the rail car and preventing over heating of the transponder when the rail car is placed in a thaw shed. The transponder is attached to the bracket by inserting a flange formed one end of the transponder under a clip projecting from the upper surface of the bracket. A threaded stud projecting upward from the bracket upper surface extends through a hole in a second flange formed at the other end of the transponder. The controlled length of the stud, and the use of an acorn nut and conical washer threaded onto the stud to clamp the transponder to the bracket, prevents generating excessive clamping force.
