A wearable electronic device with one or more receiver electrodes and a plurality of transmitter electrodes, with differential mutual-capacitance measurements used to determine wear status of the device, is described. Mutual-capacitance between receiver and transmitter electrodes is increased to compensate for weak coupling between grounded structures of the device and a surrounding electrical earth.

Differential output channels may be dynamically identified and selected to ensure accurate wear detection.

A steering wheel and a heat-conducting device are provided. The steering wheel includes a body, a handle, a heating device, an electronic control unit, a heat-conducting member and a base. The handle is adjacent to the body, and the heating device is disposed in the handle and receives a driving signal to generate heat accordingly. The electronic control unit is electrically connected to the heating device through a driving wire, and provides the driving signal to the heating device. The heat-conducting member forms a waste heat path, and the heat-conducting member and the heating device are located at different locations in the handle. The base is connected to the electronic control unit, collects waste heat from the electronic control unit, and is connected to the heat-conducting member through a heat dissipation wire to transfer the waste heat to the heat-conducting member.

An operating apparatus is disposed on a surface of a detection panel including a transparent panel and a sensor panel. An operation body includes an upper wall, an inner peripheral wall, and an outer peripheral wall. A rotary assembly is housed in the operation body.

A non-volatile, absolute rotation sensor employs a radial guide and spiral guide rotating with respect to each other to move a marker element continuously along the radial guide so that a distance of the marker element along the radial guide provides an indication of shaft movement over multiple turns. A sensor system senses the distance of the marker element along the radial guide to provide an electric output.
