Abstract:
Systems and processes for encoding and decoding touch signals output by a touch sensor are provided. In one example system, switching circuitry can be used to selectively couple each of the sense lines of a touch sensor to a positive terminal or a negative terminal of a sense amplifier based on the values of the elements of a matrix. The touch signals can be amplified and converted into digital form using a single sense amplifier and an ADC before being decoded using decoding circuitry. The decoding circuitry can decode the digital encoded touch signals by multiplying the digital encoded touch signals by each column of an inverse of the matrix used to encode the touch signals. The result of the decoding can be a set of signals that are representative of the touch signals output by the touch sensor.
Abstract:
A wireless data processing device is described which periodically exits an unpowered state and transmits location data. For example, one embodiment of a wireless data processing device comprises: power circuitry for maintaining the wireless data processing device in a powered or unpowered state, the power circuitry causing the wireless data processing device to enter into an unpowered state responsive to user input; a timer to periodically power up the wireless device or portion thereof in response to reaching a predetermined time; a location services module determining a current location of the wireless data processing device using one or more specified location determination techniques; a transmit thread transmitting the current location of the wireless device over one or more specified communication channels; and the power circuitry powering down the wireless data processing device a second time after the current location has been transmitted.
Abstract:
Some embodiments provide a vehicle that includes a protection system configured to mitigate hazards to vehicle occupants posed by dynamic elements located within proximity of the vehicle. The vehicle can, in response to determining that a dynamic element is moving along a trajectory that intersects a sweep volume of a vehicle portal, can selectively restrict operation of the portal so that an occupant is restricted from opening the portal into a volume through which the dynamic element may pass. The vehicle can restrict portal operation in response to detecting external dynamic elements that are not within an occupant's field of vision. The vehicle can communicate a limited selection of vehicle sensor data, including representations of a detected dynamic element, to a user device supporting an authorized user in response to detecting that the dynamic element is located within a certain proximity of the vehicle.
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.

Abstract:
A self-capacitance touch screen. In some examples, the touch screen comprises a plurality of display pixels, a first display pixel of the plurality of display pixels including a first touch electrode of a plurality of touch electrodes, and a gate line coupled to the first display pixel, wherein the gate line is configured such that a voltage at the gate line substantially follows a voltage at the first touch electrode. In some examples, the gate line is coupled to a resistor, the resistor being configured to decouple the gate line from ground. In some examples, the gate line is coupled to an AC voltage source.
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.
