US Patent 11034402 Bicycle control device

A wearable control unit for controlling a piece of equipment of a bicycle has a power source and a sensor powered by the power source. The sensor detects targets that are physically distinct and separate from the control unit and not electrically connected to the control unit by a wire. The control unit generates and emits an electrical command in response to a change of state of the sensor brought about by entry of the target into the sensor's detection range, and/or in response to the target exiting from the detection range of the sensor.
