摘要

ABSTRACT A computerized system 40 for locating a device. System 40 includes a sensor module 20 and a CPU 42. A radioactive source 38, associated with the device, produces a signal in the form of radioactive disintegrations. Module 20 includes radiation detector 22 capable of receiving a signal from source 38 attached to the device. Module 20 produces an output signal 34. CPU 42 receives output signal(s) 34 and translates output 34 into directional information relating to a position of source 38.
