Abstract
A disclosed wireless remote control apparatus includes a sensor, such as a capacitive sensing plate, and measurement circuitry coupled to the sensor. The measurement circuitry takes real time measurements of an electrical parameter from the sensor. The parameter, such as a capacitance or charge on the plate that relates to an electrical field in the vicinity of the sensor, represents a detection of position or movement of a member within a substantially continuous range in proximity to the sensor. In an example of a ring embodiment of the remote control device, the sensor detects position and/or movements in relation to the operator's finger. The remote control apparatus includes a wireless transmitter for wireless transmission of encoded messages and a controller. The controller controls the transmitter, to set durations of intervals between the message transmissions as a function of the measurements of the electrical parameter.
