Abstract: A computing device, such as a wearable device, may include a light source and a photodetector array. The photodetector array may be used to determine a touch event of a user that occurs during a time interval. A subset of the plurality of photodetectors associated with the touch event may provide detection signals at each of a plurality of times within the time interval, which may be aggregated to obtain a time series of aggregated detection signals. Biometric data of the user may be generated, based on the time series of aggregated detection signals.

Abstract: Methods, systems, and apparatus, for sensing a touch on a display panel including an array of pixels. A method includes controlling first pixels to operate in an illumination state; controlling second pixels to repeatedly switch between operating in the illumination state and operating in a sensing state; generating sensing signals indicative of levels of light detected by the second pixels; detecting a touch input to the display panel based on the generated sensing signals; and in response to detecting the touch input to the display panel, changing at least one of (i) a frequency at which the second pixels switch between operating in the illumination state and in the sensing state, (ii) a duty cycle for operating the second pixels in the sensing state, or (iii) which of the pixels in the array of pixels are controlled to switch between operating in the illumination state and in the sensing state.

Abstract: Remote biometric monitoring systems may include a digital camera having a digital sensor, a processor, and a memory, all enclosed in a common housing. The processor of the camera may locally execute one or more algorithms to perform computer vision analysis of captured images of a sleeping subject, thereby determining an activity state of the subject. The activity state may include a sleep state. One or more environmental control devices may be adjusted automatically by the system based at least in part on the activity state.

Abstract: Various arrangements for monitoring the health of a sleeping child are presented. The system can include a camera configured to capture images. The system can include an environmental sensor such as a humidity or temperature sensor. The system can include a microphone. The system can include a processor configured to receive and analyze the images and data to determine (i) a plurality of biometric parameters relating to the child including at least length of sleep, sleep quality, sleep cycle information, and a breathing pattern, and (ii) whether the local environment falls within predetermined temperature or humidity limits. The system can include a remote notification device configured to provide information relating to the biometric parameters and the local environment to a user located out of sight of the child. A confidence level of a subject presence determination may be adjusted based on biometric analysis of a candidate subject location.
