Abstract
An electrically powered resistance heating handgrip includes a control circuit located within a hollow core that fits coaxially within the open end of a handlebar of a motorcycle or snowmobile. The control circuit is mounted on a thin, narrow, elongated printed circuit board and includes a microprocessor that is programmed to contain a lookup table of temperatures. A thermistor provides feedback signals to the microprocessor which compares temperature sensor feedback signals to a target temperature. The target temperature is established by a dial. The dial operates the wiper of a variable potentiometer to establish the target temperature. Heat is uniformly distributed by wrapping the heating element wire thereof about a thermally conductive sheet of aluminum, and encasing the wire within a temperature resistant dielectric sheathing.
