摘要

A device identification system for use with a device having an inductive secondary comprises a power supply including an inductive primary and being capable of driving the inductive primary at a plurality of frequencies and measuring means for measuring a response of the inductive secondary to each of the frequencies. The plurality of responses forms a frequency response profile. The system further comprises memory means for storing a plurality of device identifiers each associated with one of the frequency response profiles. The device identifiers include information regarding the use of the device. The system further comprises a processor means operatively coupled to the power supply, the measuring means, and the memory means. The processor means is 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. device identification system is part of a food preparation system.
