A motor-driven dental device has a motor control that is responsive to a load placed upon the motor. More specifically, the invention relates to a dental device having motor that drives a tool, wherein the tool is activated or otherwise controlled in response to a load placed upon the motor through the tool, such as by touching the tool to a surface. The tool may also be controlled by the sustenance, over a predetermined time period, of an increase or decrease in motor current beyond a predetermined hysteresis current threshold. The motor may be an electric motor, a rotary electric motor, and air driven motor, an ultrasonic device or the like.

A method and system for determining whether or not passive entry of a vehicle is permitted, includes allocating separate channels for each authorized key FOB for the vehicle. An indication of manual entry of the vehicle is detected. Upon such detection, a challenge from a transmitter of a passive entry system is output. The challenge is received by more than one key FOB in a vicinity of the vehicle, and outputting a respective remote keyless entry response at an assigned frequency channel for each respective key FOB. The remote keyless entry responses are received at a receiver of the passive entry system, at each respective channel allocated for the respective key FOBs. A determination is then made as to whether or not any of the respective key FOBs are assigned to authorized users of the vehicle, and if so, a vehicle door is set in an unlocked state to allow entry into the vehicle.
