1. A device identification system for use with a device having an inductive secondary, the system comprising:
- a power supply including an inductive primary and being capable of driving the inductive primary at a plurality of frequencies;
measuring means for measuring a response of the inductive secondary to each of the frequencies, the plurality of responses forming a frequency response profile;
memory means for storing a plurality of device identifiers each associated with one of the frequency response profiles, the device identifiers including information regarding the use of the device; and
a processor means operatively coupled to the power supply, the measuring means, and the memory means, the processor means being for compiling the frequency response profile, for selecting from the memory means the device identifier and the associated use information as a function of the frequency response profile, and for controlling the power supply in accordance with the associated use information.

Abstract
A food preparation system includes a non-contact power supply for energizing a cooking appliance. The food preparation system includes a communication system for enabling communication between a food appliance and the system. The appliance transmits an identifier to the system. If the appliance does not have a transmitter, the system attempts to determine the type of appliance from a characterization of the power consumption by the appliance. If the appliance cannot be characterized, the food preparation system can be operated manually.
