Abstract: A scanning operation is performed to measure a first capacitance of a first sensor arrangement located proximate a capacitive sensor that corresponds to a function of a device. In response to the first capacitance not exceeding a first threshold, the scanning operation measures a second capacitance of the capacitive sensor to create an output used to control the function of the device. In response to the first capacitance exceeding the first threshold, operation of the scanning operation is modified to skip measuring of the second capacitance or to refrain from transmitting the output to a host of the device for controlling the function.

Abstract: A rotary encoder for capturing angular position of a target rotating over capacitive sensors. The rotary encoder includes a source plate. The rotary encoder includes a pair of capacitive sensors coupled to the source plate, and a target plate separated from the source plate by a gap. The target plate includes a spoke and a flange. The spoke is capacitively coupled to the pair of capacitive sensors and the flange is capacitively coupled to a ground pad. Each capacitive sensor of the pair of capacitive sensors is configured to detect a change in a capacitive value corresponding to an angular position of the spoke to the capacitive sensor. The target plate is mechanically coupled to a joystick. A movement of the joystick causes a rotation of the target plate about an axis to change the angular position of the spoke to the pair of capacitive sensors.

Abstract: An intelligent strobe system for vehicle applications includes strobe modules connected between the positive and negative DC power rails of the vehicle. One of the strobe modules includes a transmitter circuit for generating sinusoidal data and transmitting the data over the DC power rails. Other strobe modules include a receiver circuit to receive and decode the sinusoidal data to control the flash sequence.
