  • Patent number: 9880675
    Abstract: A capacitive fingerprint sensor that may be formed of an array of sensing elements. Each capacitive sensing element of the array may register a voltage that varies with the capacitance of a capacitive coupling. A finger may capacitively couple to the individual capacitive sensing elements of the sensor, such that the sensor may sense a capacitance between each capacitive sensing element and the flesh of the fingerprint. The capacitance signal may be detected by sensing the change in voltage on the capacitive sensing element as the relative voltage between the finger and the sensing chip is changed. Alternately, the capacitance signal may be detected by sensing the change in charge received by the capacitive sensing elements as the relative voltage between the finger and the sensing chip is changed.

  • Patent number: 9864507
    Abstract: A method and device are provided for measuring force on a force enabled input device having a touch surface. The method includes detecting force information associated with an input object contacting the touch surface, and determining a push event if the force information is either greater than a predetermined static push threshold value, or a substantially monotonic increase of at least a dynamic push threshold value above a low baseline value. The method thereafter determines a release event if the force information either decreases below a predetermined static release threshold value, or decreases from a maximum baseline value by an amount greater than a dynamic release threshold value. The method initiates a first type of user interface action associated with the input object based on a determination of the push event and the release event, wherein the first type of user interface action may comprise determining a virtual button click.

  • Patent number: 9857394
    Abstract: Relative capacitance of a plurality of capacitive sensors may be monitored by using only one ADC conversion. A plurality of capacitive sensors individually charges a sample and hold capacitor. After all of the plurality of capacitive sensors have charged the sample and hold capacitor, a digital conversion of the resulting analog on the sample and hold capacitor is made and stored in a memory. This stored digital collective voltage is compared to a previously stored one and if different then a proximity/touch event may have occurred. Therefore, an entire panel of capacitive sensors may be quickly monitored for a change in the “group” capacitance thereof, or portions of the capacitive sensors may be monitored for a change in the “subgroup” capacitance thereof. By knowing which subgroup of capacitive sensors has changed its collective capacitive value, a more focused and selective capacitive sensor measurement can be made that uses less power.
