Abstract:
A coin-handling apparatus comprising:a first region for receiving a plurality of coins of a plurality of denominations in random orientation; means for singulating at least some of said plurality of coins and transporting along a path toward at least a first sensing location; at least a first sensor for receiving at least first and second driving signals for driving said sensor and providing sensor output, said sensor output including at least a first signal, said output being indicative of at least a first low-frequency coin characteristic and a second high-frequency coin characteristic, said sensor further including a unitary magnetic core and first and second windings wrapped about said unitary magnetic core, wherein said first driving signal is provided to said first winding and said second driving signal is provided to said second winding, and wherein said first winding has a first axis and said second winding has a second axis different from said first axis; and circuitry coupled to said at least first sensor for receiving at least said sensor output and outputting at least a second signal indicative of whether a sensed object is an acceptable coin.
