摘要： A method of resetting a digital counter for a personal care appliance by sending an electrical output signal from an optical sensor to a control circuit. The electrical output signal is compared to a predetermined value with the control circuit or a change in the electrical output signal from the optical sensor is detected over time. A signal is sent to a consumer user interface by the control circuit based on the electrical output signal and the predetermined value or based on the change in the electrical output signal from the optical sensor. The digital counter is reset based on an input signal from the consumer user interface.

摘要： A grooming device. The grooming device includes a handle having a neck portion, a displacement sensor positioned within the neck portion, a housing portion, a coupling mechanism securing the neck portion and the housing portion to one another, and a power source positioned within the handle. The neck portion includes a proximal end and a distal end. The proximal end of the neck portion having an implement connecting structure. The housing portion includes a proximal end, a distal end, and a location element. The proximal end of the housing portion is pivotably connected to the distal end of the neck portion about a handle pivot axis. As the neck portion pivots about the handle pivot axis relative to the housing portion, the displacement sensor detects displacement of the location element. A grooming implement is connected to the implement connecting structure.
