Abstract

A method and apparatus which allows one toy (101) to identify a plurality of objects (107) is provided. The system relies on the inductive coupling of the toy with a tank circuit (109) contained within the object to be identified and therefore does not require physical contact between the toy and the object. The sensing circuit includes a variable frequency RF oscillator (103) and an air wound coil to radiate a magnetic flux. The resonant frequency of a tank circuit inductively coupled to the sensing circuit serves to identify the object. In one approach, the frequency of the RF oscillator is varied over a range of frequencies while the current drawn by the oscillator is monitored. In another approach, the object identifying function is broken up into an oscillation generating step and an oscillation sensing step. During the sensing step, the toy monitors for ringing emitted by the tank circuit of an object.
