Patent ID: 7405675

Claim:
A method of determining the resonant frequency of a resonant device, said method comprising the steps of: partitioning a first designated frequency range into at least two respective first search frequency ranges; energizing the resonant device by transmitting one or more respective first RF pulses characterized by a first bandwidth in selected of the at least two respective first search frequency ranges; monitoring the response of said resonant device to the one or more first RF pulses to determine if the amount of energy radiated by said resonant device exceeds a first predetermined threshold level; and if the amount of energy radiated by said resonant device in response to the one or more first RF pulses transmitted in selected of the at least two respective first search frequency ranges does not exceed the first predetermined threshold level, repeating said partitioning, energizing and monitoring steps for additional respective search frequency ranges within the at least two respective first search frequency ranges until the amount of energy radiated by said resonant device in response to the one or more first RF pulses exceeds the predetermined threshold level.
