摘要： Techniques and apparatuses are described that implement a smart-device-based radar system capable of determining characteristics of objects external to a vehicle, occupants within a vehicle, and objects proximal a open-air vehicle. In particular, the system enables a smart device to perform many vehicle operations such as collision avoidance, occupant detection, and parking assistance in vehicle and open-air vehicle environments without integrated radar technology. By using a smart device to perform such actions, existing vehicles and open-air vehicles without integrated radar functionality may be able to leverage radar-based vehicle operations.

摘要： This document describes techniques for color correction using a sensor to reduce color distortions of a camera under a display of a computing device. A correction module of the computing device may determine a color correction used to improve content captured by a camera utilizing, in part, a sensor (e.g., a camera, ambient light sensor, and so forth) positioned underneath the display. The sensor may detect ambient light over time that is modified as it travels through the display, producing color distortions. The sensor may also detect a composite light over time that includes calibration light emitted by the display and ambient light. The correction module may compare the ambient light and composite light to determine the color correction usable to improve both the content captured by the camera and a user experience.

摘要： A mobile computing device an emissive display that includes a touchscreen and a proximity sensor. The proximity sensor includes a transmitter configured to transmit electromagnetic radiation through the display and a receiver of electromagnetic radiation configured to receive electromagnetic radiation transmitted by the transmitter, reflected off an object facing the emissive display and received through the emissive display. The proximity sensor is configured for generating a quantitative output signal based on an amount of the received electromagnetic radiation, and the transmitter is configured to transmit a first predetermined amount of light when a distance between the object and the display is greater than a near threshold distance between the object and the display and is configured to transmit a second predetermined amount of light when the distance between the object and the display is less than the near threshold distance. The second predetermined amount is greater than the first predetermined amount. A processor is configured for receiving the generated quantitative output signal, and memory stores instructions that, when executed by the processor, cause the processor to deactivate the touchscreen and/or the emissive display when the touchscreen and/or the emissive display is activated and when the quantitative output signal increases above an high threshold value and to activate the touchscreen and/or the emissive display when the touchscreen and/or the emissive display is deactivated and when the quantitative output signal is below a low threshold value, the low threshold value being less than the high threshold value.

摘要： A mobile computing device includes one or more processors, an emissive display that includes a touchscreen, and a proximity sensor that generates a quantitative output signal. The one or more processors transition, in response to the quantitative output signal decreasing below a low threshold value, operation of the sensor to a high sensitivity state; transition, in response to the quantitative output signal increasing above a high threshold value, operation of the sensor to the low sensitivity state; and deactivate the touchscreen and/or the emissive display when the touchscreen and/or the emissive display is activated and when the quantitative output signal increases above an high threshold value and to activate the touchscreen and/or the emissive display when the touchscreen and/or the emissive display is deactivated and when the quantitative output signal is below a low threshold value, the low threshold value being less than the high threshold value.
