  • Patent number: 10222241
    Abstract: A capacitance measurement circuit for determining a capacitance of a guard-sense capacitive sensor includes a microcontroller that uses a combination of several synchronized PWM outputs for generating a low distortion sine wave. The sine wave is used as a guard voltage for the guard electrode of the capacitive sensor. The capacitance value of an unknown capacitor is measured by impinging the guard voltage on the sense electrode of the capacitive sensor by a modified sigma-delta modulator unit. The digital output of the sigma-delta modulator unit is first multiplied by an XOR gate before being routed into a decimator/low pass filter. The second input of the XOR gate is driven by a square wave from a square wave generator with the same frequency as the guard voltage, but with a substantially 90° phase shift. The output of the decimator/low pass filter is indicative of the capacitance value of the unknown capacitor.

  • Patent number: 10175278
    Abstract: An output capacitor of a switching converter filters the triangular current waveform output by an inductor. An auxiliary capacitor, having a capacitance that is much smaller than a capacitance of the output capacitor, is coupled in parallel with the output capacitor so as to conduct a portion of the inductor current. A slope detector circuit determines a slope of the auxiliary capacitor current, and outputs a slope signal corresponding to the slope. A process circuit receives the slope signal and a signal corresponding to the inductor current. Since the auxiliary capacitor current slope is known, along with the auxiliary capacitance value and inductor current, the process circuit can derive the value of the output capacitor by applying a scaling factor. The derived value can be used to dynamically tweak the compensation of the feedback loop or identify a failure of the output capacitor.

  • Patent number: 10139890
    Abstract: Automatic low noise frequency selection for a touch sensitive device is disclosed. A low noise stimulation frequency can be automatically selected by device logic without intervention of the device processor to stimulate the device to sense a touch event at the device. The device logic can automatically select a set of low noise frequencies from among various frequencies based on the amount of noise introduced by the device at the various frequencies, where the frequencies with the lower noise amounts can be selected. The device logic can also automatically select a low noise frequency from among the selected set as the low noise stimulation frequency. The device logic can be implemented partially or entirely in hardware.

  • Patent number: 10047459
    Abstract: This document describes interactive cords. An interactive cord includes a cable, and fabric cover that covers the cable. The fabric cover includes one or more conductive threads woven into the fabric cover to form one or more capacitive touchpoints which are configured to enable reception of touch input that causes a change in capacitance to the one or more conductive threads. A controller, implemented at the interactive cord or a computing device coupled to the interactive cord, can detect the change in capacitance and trigger one or more functions associated with the one or more capacitive touchpoints. For example, when implemented as a cord for a headset, the controller can control audio to the headset, such as by playing the audio, pausing the audio, adjusting the volume of the audio, skipping ahead in the audio, skipping backwards in the audio, skipping to additional audio, and so forth.
