Abstract: Reducing power consumption in a touch screen. In some examples, a first level of touch accuracy can be determined, and a first portion of the touch screen can be operated in a first mode corresponding to the first level of touch accuracy. In some examples, a second level of touch accuracy can be determined, and a second portion of the touch screen can be operated in a second mode corresponding to the second level of touch accuracy. The first and/or second levels of touch accuracy can be determined based on an application running on a device including the touch screen and/or a user interface displayed on the touch screen. In some examples, in the first and/or second modes, the respective portions of the touch screen can transition between a touch sensing phase and a display phase at different transition frequencies and/or can sense touch at different ratios of touch sensors.

Abstract: Electrodes that can be used to determine a first type of physiological signal and a second type of physiological signal are disclosed. The first type of physiological signal can be electromyography (EMG) signals produced by activity of muscles and tendons. Identification of hand movements can be supplemented with pose detection circuitry such as inertial measurement units (IMUs). These EMG signals can be processed to identify hand movements and recognize gestures associated with those hand movements. The second type of physiological signal can be electromyography (ECG) signals produced by the heart. The electrodes can be used to detect EMG and ECG signals dependent upon a current configuration of sensing circuitry. The electrodes can be used to determine a measurement quality associated with the EMG signals.
