Abstract: An electronic device with hybrid power source includes a system circuit, a charging and discharging circuit, a power connector, two batteries, and a controller. The charging and discharging circuit is connected to the system circuit, the power connector, and the two batteries. The controller is connected to the processor and the charging and discharging circuit, and the controller has a hybrid power supply mode. The controller detects the operating power of the processor in the system circuit, and controls the power mode from a single power mode to a hybrid power supply mode in response to that the operating power reaches or exceeds the power threshold. In the hybrid power supply mode, under control of the controller, the processor releases a power limit, and the charging and discharging circuit powers the system circuit by using both the battery with greater energy level and an external power.

Abstract: A control system for a screen of a vehicle includes a global positioning system (GPS), an inertia sensor and a control circuit. The GPS detects a satellite signal from a satellite. The inertia sensor senses motion of the vehicle and correspondingly generates a motion state value. The control circuit performs one of a first determination procedure and a second determination procedure according to the state of the satellite signal. In the first determination procedure, the control circuit calculates the vehicle speed of the vehicle according to the satellite signal, and selectively locks the screen of the vehicle according to the vehicle speed. In the second determination procedure, the control circuit generates a motion signal according to the motion state value, and selectively locks the screen of the vehicle according to the motion signal. Accordingly, driving safety can still be effectively ensured even in the case of poor satellite signals.

Abstract: A detecting circuit of an external display device includes a first connector, a display circuit configured to provide a display signal to the external display device through the first connector, a switch circuit, a power supply circuit configured to provide power needed for operating the display circuit through the switch circuit when the switch circuit is on, and a control circuit configured to turn on the switch circuit upon detecting the external display device so as to connect the power supply circuit to the display circuit. When the switch circuit is on, the control circuit accumulates a duration or a number of times of detection that the external display device is continually not detected, and then turns off the switch circuit to disconnect the power circuit from the display circuit when the duration reaches a time threshold or the number of times of detection reaches a count threshold.
