Abstract

We describe the placement of an amorphous magnetic wire that is interrogated by a magnetic field and responds by transmitting a unique signature that can be sensed for the purposes of theft detection. The wire (manufactured by Unitika Corp) is capable of emitting a distinctive signature for wire lengths considerably shorter than previously possible with magnetic wires. Because of its operable condition using short and straight lengths, it is possible to readily mount the wire on small items such as logic chips or newer generations of memory chips for antitheft protection. This wire is available in much smaller diameters than previous wires, for example as small as 50 microns. This diameter makes it possible for placing the wire between lamination layers of circuit boards as well as between ceramic layers on logic chips. The smaller dimension also makes it possible to attach and conceal the wire on various computer elements utilizing concealed grooves or placement underneath the wiring of SIMMS and DIMMS. The amorphous wire can also be concealed under a label attached to the electronic part, sandwiched between the label and the part. Wires with diameters as small as 50 microns are available. In the presence of an alternating magnetic field, the wire’s non-linear magnetic signature can be detected by a coil and subsequently frequency analyzed. The presence of the appropriate frequencies indicating theft can be used to set off an alarm.
