Abstract: A personal care appliance is provided that includes a brushhead for use in skincare; an appliance body having a motor assembly for oscillating the brushhead, wherein the brushhead or a portion of the motor assembly that is configured to oscillate includes a marking; and a brush encoder configured to detect the marking, and determine the oscillation of the brushhead.

Abstract: Systems configured to couple with and identify encoded end effectors and related methods of use are described.

Abstract: A system to promote optimum performance of a personal care appliance is provided including: a personal care appliance having an appliance status; and a client device, in communication with the appliance, including circuitry configured to compare the appliance status with the protocol for using the appliance, control display of an indicator based on the comparison.

Abstract: Piezoelectric systems and appliances for removing eye makeup and related methods are described.

Abstract: A method for controlling display of a user interface for optimizing performance in using a personal care appliance is provided including: receiving a user info or regimen; receiving a protocol or routine to use the appliance; receiving an appliance status related to a user's usage of the appliance; comparing the appliance status to a target usage of the appliance in the protocol or routine; and controlling display of an indicator of the user's performance based on the comparison.

Abstract: The appliance includes an appliance body/handle and an interface assembly for receiving a detachable workpiece. The body/handle includes a signal-generating assembly with electrical connections to the appliance body interface. The signal-generating assembly is controlled by a microprocessor, which generates signals adapted to control and operate the workpiece which is attached to the appliance. A plurality of workpieces are included which are individually adapted for treating various spot skin irregularities. The appliance further includes a system for identifying the workpiece attached, so that appropriate operating signals can be generated and provided to the attached workpiece.

Abstract: A personal skincare appliance is provided that includes a brush head; a motor configured to cause angular rotation of the brush head; and a controller configured to control a drive frequency of the motor. The controller is configured to detect an event corresponding to a status or condition of the personal skincare appliance and to set the drive frequency of the motor to a predetermined frequency which causes an auditory tone to be emitted from the personal skincare appliance.

Abstract: The skin brush appliance includes a handle member with a replaceable brushhead assembly. The replaceable brushhead assembly includes a bristle portion which becomes worn in use to the point where it must be replaced to maintain performance of the appliance. An LED light is provided in the vicinity of the bristle portion which is controlled to come on when the bristle assembly is in need of replacement.

Abstract: An electronic appliance having control firmware includes an operating part which requires periodic replacement for effective operation of the appliance. The replacement operating part has an RFID tag attached thereto which includes updated firmware for the appliance. The appliance further includes an RFID reader which reads the updated firmware on the RFID tag when the replacement part is operatively positioned in the appliance, and updates/replaces the existing firmware or a portion thereof with the read firmware.

Abstract: Control modules for automatically adjusting a laser output based on a range to an object detected within a field of view are disclosed.

Abstract: A circuit for detecting a phase error between a clock signal and a beam position includes a beam generator, sensor, and phase detector. The beam generator directs a beam toward a beam sweeper in response to a clock signal. The sensor, which is disposed at a mid line of a region that the beam sweeper scans, detects the beam from the beam sweeper, and the phase detector detects an error in the clock phase from the detected beam. Such a circuit can automatically detect the phase error in the pixel clock and correct this error, thus eliminating the need for a manual phase-error corrector.

Abstract: Laser systems and methods having an ability to automatically adjust a laser output based on one or more of a state of an object detected within a field of view and a motion of the laser system are disclosed.
