Abstract: This application discloses a system for turning off power consumption of an auxiliary startup circuit. An oscillator generates a switch control signal based on a reference current output by a circuit to be started up to generate a working clock of a switch control signal generation circuit after the circuit to be started up works normally. After fixed clock signal counting, the switch control signal generation circuit outputs a switch control signal to control power consumption of normally open current of the auxiliary startup circuit to be turned off. At the same time, the switch control signal generation circuit stops counting the clock. This application can assist the circuit to be started up having a “degeneracy” bias point to power on normally, and can also turn off the power consumption of the auxiliary startup circuit after the circuit to be started up is powered on.

Abstract: An electronic device may include a proximity sensor and a display. In particular, the display may be deactivated when the device is near a user's head. However, the proximity sensor may operate through or near the display and may detect the user's finger. Therefore, to distinguish between the user's finger and head, a motion sensor, such as an inertial measurement unit (IMU) may be used. For example, the position, acceleration, and rate of rotation of the device may be measured by the IMU, and a machine-learning algorithm may take the position, acceleration, and rate of rotation as inputs to determine whether the proximity sensor is triggered by the user's finger or head. In response to determining that the proximity has been triggered by the head, the display may be deactivated. Alternatively, in response to determining that the proximity sensor has been triggered by the finger, the display may remain on.
