Abstract
The compensating/performance regulation system includes a power skin brush having a handle, an oscillating brushhead workpiece and a drive system, wherein the brushhead workpiece has an RFID tag. An RFID reader is provided in the handle and is responsive to the RFID tag moving past the reader to produce an indication of use of the brushhead. A microprocessor calculates a value of actual use from the RFID information and uses stored information to determine the decline in performance from the calculated use. A compensating change in drive frequency or duty cycle of the drive signal is then determined by the microprocessor from stored information and transmitted to the drive system to maintain performance of the appliance.
