Abstract: A self-capacitance touch sensor panel including a plurality of touch electrodes and one or more sense circuits coupled to the touch electrodes. The touch sensor panel also includes at least one offset cancellation circuit coupled to at least one of the touch electrodes and configured to generate an offset cancellation signal to cancel an offset signal at the at least one touch electrode. In some examples, the offset cancellation signal can be an offset cancellation current to cancel an offset current. In some examples, the offset cancellation circuit comprises a variable resistor, and a magnitude of the offset cancellation current is based on a resistance of the variable resistor. In some examples, each touch electrode is coupled to an offset cancellation circuit. In other examples, a single offset cancellation circuit is shared by a plurality of touch electrodes.

Abstract: Systems, methods, and devices are provided to identify the occurrence, location, and/or severity of a fracture within an integrated circuit, even when the integrated circuit is not accessible to external inspection. One such method includes obtaining a measurement of a property of the integrated circuit through at least one contact of the integrated circuit. The measurement may include a resistance of a resistive pattern in the integrated circuit or a measurement of current-voltage behavior of a power supply of the integrated circuit. The measurement of the property may be compared to an expected baseline property. Based at least in part on this comparison, whether a fracture of the integrated circuit has occurred and a location of the fracture in the integrated circuit may be determined.

Abstract: Systems, methods, and devices for calibrating an electronic display to reduce or eliminate a mura artifact are provided. The mura artifact may be due to differential behavior of common voltage layers (VCOMs) in the electronic display. One method for reducing or eliminating the mura artifact may involve setting pixels of the electronic display to a first gray level and measuring a luminance difference between light and dark areas of a mura artifact on the electronic display. A value of an operating parameter of the electronic display may be adjusted while monitoring the luminance difference measurement. A value of the operating parameter that causes the luminance difference measurement to be within a specified range of acceptable luminance difference measurement values may be stored in the electronic display.

Abstract: Autonomous navigation of a vehicle along one or more portions of a driving route based on monitoring, at the vehicle, various features of the route as the vehicle is manually navigated along the route to develop a characterization of the route is described. The characterization is progressively updated with repeated manual navigations along the route, and autonomous navigation of the route is enabled when a confidence indicator of the characterization meets a threshold indication. Characterizations can be updated in response to the vehicle encountering changes in the route and can include a set of driving rules associated with the route, where the driving rules are developed based on monitoring the navigation of one or more vehicles of the route. Characterizations can be uploaded to a remote system which processes data to develop and refine route characterizations and provide characterizations to one or more vehicles.

Abstract: Automated capture of image data for points of interest may be implemented for points of interest in an environment external to a vehicle. Sensors implemented as part of a vehicle may collect sensor data for an environment. Processing of the sensor data may be performed to detect points of interest in the environment. In response to detecting a point of interest, image data may be captured by one or more of the sensors implemented at the vehicle. Different types of image data may be captured, such as panoramic images and three-dimensional reconstructions of a scene. Metadata may be generated for captured image data which may describe the point of interest that is captured by the image data. The image data and the metadata may be stored locally at the vehicle or to a remote data store. The image data may also be shared with other computing devices.

Abstract: A self-capacitive touch sensor panel configured to have a portion of both the touch and display functionality integrated into a common layer is provided. The touch sensor panel includes a layer with circuit elements that can switchably operate as both touch circuitry and display circuitry such that during a touch mode of the device the circuit elements operate as touch circuitry and during a display mode of the device the circuit elements operate as display circuitry. The touch mode and display mode can be time multiplexed. By integrating the touch hardware and display hardware into common layers, savings in power, weight and thickness of the device can be realized.

Abstract: Aspects of the present disclosure involve a method for determining a road vehicle velocity and slip angle. The current disclosure presents a technique for identifying a vehicle's velocity and slip angle, in the vehicle's coordinate frame. In one embodiment, two or more sensors are orthogonally located on the underside of the vehicle in order to obtain longitudinal and lateral velocity information for slip angle determination. In another embodiment, the two or more sensors can include an array of elements for beam steering and receiver beamforming. Spatial diversity is leveraged in identifying at least a slip angle and/or velocity of the vehicle. Doppler mapping is used as a means for slip angle determination and the clutter ridge of the Doppler map is embraced for identifying the slip angle.

Abstract: Some embodiments provide a sensor data-processing system which detects and classifies objects detected in an environment via fusion of sensor data representations generated by multiple separate sensors. The sensor data-processing system can fuse sensor data representations generated by multiple sensor devices into a fused sensor data representation and can further detect and classify features in the fused sensor data representation. Feature detection can be implemented based at least in part upon utilizing a feature-detection model generated via one or more of deep learning and traditional machine learning. The sensor data-processing system can adjust sensor data processing of representations generated by sensor devices based on external factors including indications of sensor health and environmental conditions. The sensor data-processing system can be implemented in a vehicle and provide output data associated with the detected objects to a navigation system which navigates the vehicle according to the output data.
