Abstract: A light ranging and detection (LiDAR) device may combine the transmission of laser pulses. Different trains of pulses from different transmitters may be combined and transmitted to an environment via a common optical path. The laser pulses transmitted from one train of pulses may be in a polarization state that is orthogonal to a polarization state for the laser pulses of the other train of pulses. Reflections for the different trains of pulses may be received via the common optical path and separated according to polarization state. Reflections of the train of pulses may be directed to one receiver and reflections of the other train of pulses may be directed to a different receiver. The transmission delta between the different trains of pulses may be dynamically configured. The pulse repetition rate of each train of pulses may also be configured.

Abstract: A sensor system and method that adjusts sensor data to account for the presence of noise that causes variations in signal amplitude between sensor blocks and between sensor rows. In order to account for the presence of noise in a sensor apparatus, various embodiments apply a first adjustment to the sensor data to account for variations in signal amplitude that occur from block to block. Various embodiments may also apply a second adjustment to the sensor data to account for variations in signal amplitude that occur from row to row.

Abstract: A fingerprint sensor is incorporated in a display stack in an electronic device. A single fingerprint can be captured at one time at a single pre-defined fixed location on a display. Alternatively, a single fingerprint can be acquired at one time at any location on a display. Alternatively, multiple touches on the display can be acquired substantially simultaneously where only one fingerprint is captured at a time or where all of the fingerprints are acquired at the same time. The fingerprint sensor can be implemented as an integrated circuit connected to a bottom surface of a cover sheet, near the bottom surface of the cover sheet, or connected to a top surface of a display. Alternatively, the fingerprint sensor can be implemented as a full panel fingerprint sensor.

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.

Abstract: A touch sensor panel is disclosed. The touch sensor panel includes a first set of touch electrodes configured to operate as drive lines and that are disposed in a first layer of the touch sensor panel. The touch sensor panel also includes a second set of touch electrodes configured to operate as sense lines and that are disposed in a second layer of the touch sensor panel, different than the first layer of the touch sensor panel, such that one or more mutual capacitance touch nodes are formed by the first set of touch electrodes and the second set of touch electrodes. The touch sensor panel also includes a third set of touch electrodes configured to operate as self-capacitance electrodes and that are disposed in the first layer or the second layer of the touch sensor panel.

Abstract: A biometric sensing system includes discrete ultrasonic transducers, a first electrode layer disposed over a first surface of the discrete ultrasonic transducers, and a second electrode layer disposed over a second surface of the discrete ultrasonic transducers. The first electrode layer may be a sheet of conductive material that is a common ground connection for the discrete ultrasonic transducers. Alternatively, the first electrode layer can be formed with discrete electrode elements, with a discrete electrode element disposed over the first surface of a discrete ultrasonic transducer. The second electrode layer may be formed with discrete electrode elements, with a discrete electrode element disposed over the second surface of one ultrasonic transducer. At least one integrated circuit can be attached and connected to one of the electrode layers. The integrated circuit includes drive circuits and sense circuits for the discrete ultrasonic transducers.

Abstract: An acoustic fingerprint imaging system having a plurality of acoustic elements, each acoustic element including a transducer, and independent drive and sense circuitry is disclosed. Drive circuitry may require higher voltage than low voltage sense circuitry. Many embodiments described herein include a ground shifting controller to apply a voltage bias to the low voltage sense circuitry during a drive operation, in order to prevent electrical damage to the sense circuitry.

Abstract: Some embodiments provide a vehicle which includes a one or more sets of light emitter devices and sensor devices included in a common element assembly of the vehicle which includes a common window element via which the light emitter devices and sensor devices can interact with an external environment in which the vehicle is located. The sensor devices and light emitter devices can be communicatively coupled, and operation of the light emitter devices and sensor devices can be adjustably controlled to mitigate interference by the light emitter devices with sensor data representations generated by the sensor devices. The window element can include a reflection-mitigating layer which mitigates reflection of light beams emitted by one or more light emitter devices in an assembly towards one or more sensor elements of one or more sensor devices included in the same assembly.
