Abstract: A device for sensing unauthorized use of an electronic security device has a host device and a detector with a loop antenna associated with the port that receives the electronic security device, such as a smart card. The host device comprises a housing having the port formed therein. In one embodiment, the port detector senses radiation emitted from unauthorized use of the electronic security device by attachment of hot-wire conductors to the security device, which conductors carry currents through the port and the detector. In an alternate embodiment, the dielectric constant of the electronic security device is measured and compared to a predetermined value for distinguishing a nominal device from one with attached hot wiring.

Abstract: An arrangement for dissipating heat from a circuit element attached to a printed circuit board, comprising: a heatsink having a pair of arms, each one of the arms having tips including bumps, and a structure coupled to the printed circuit board on at least two sides. The structure has holes structured and arranged to allow each of the bumps on the tips of the arms to fit into the holes of the structure.
