Embodiments relate to sensors, such as speed sensors and angle sensors, that use a modulated supply voltage to approximately double output signals of the sensors because the sensor element and the supply voltage exhibit the same frequency. A second terminal of each of the gate resistors provided for each of the plurality of insulated gate transistors is connected to the gate voltage application unit via a gate voltage apply line, and a single capacitor is connected between the gate voltage apply line and the high voltage line. The system then evaluates a diffuse contribution using the parametric texture map coefficients. Then an update to the one or more configuration files may be received. The signal transmitterreceiver also receives the positioning related information determined according to the positioning signal from the external device.
