Abstract: An electronic device with a connector supporting multiple connection standards includes the connector, a processor, a controller, an EDID (Extended Display Identification Data) ROM, a first multiplexer circuit and a second multiplexer circuit. The first multiplexer circuit is coupled to at least one signal pin of the connector, the processor and the controller. The second multiplexer circuit is coupled to the EDID ROM, the first multiplexer circuit, the processor and the controller. Under an update state, the controller is electrically connected to the EDID ROM through the second multiplexer circuit, and updates EDID in the EDID ROM with update data.

Abstract: A vehicle power management system and a power management method thereof are provided. The power management method includes: determining, by a microcontroller, whether or not a voltage of an ignition-off signal is less than a voltage threshold when the microcontroller receives the ignition-off signal; stopping a vehicle power supply from charging a backup battery, and using the vehicle power supply to charge a back-end load; activating a counter of the microcontroller; stopping the vehicle power supply from charging the back-end load, and using the backup battery to charge the back-end load when a counting time of the counter reaches a first time threshold; sending, by the microcontroller, the ignition-off signal to the back-end load when the counting time of the counter reaches a second time threshold; and stopping the backup battery from charging the back-end load when the counting time of the counter reaches a third time threshold.

Abstract: A vehicle power supply circuit monitoring system and a vehicle power supply circuit monitoring method are provided. The vehicle power supply circuit monitoring system is adapted to a vehicle power supply and a vehicle load device, and includes a power monitoring circuit and a control circuit. The power monitoring circuit is electrically connected to the vehicle power supply and the control circuit. The power monitoring circuit monitors two different input load powers at two different time points. The control circuit calculates an external power loop equivalent impedance according to the two different input load powers. When the external power loop equivalent impedance is greater than a designed impedance threshold, the control circuit executes a warning procedure.

Abstract: A sensor device, a holster sensing system, and a video-recording system are provided. The sensor device includes a control unit and a sensing module. The sensing module includes a reference coil set and an induction coil set that are arranged in a stacked structure. The sensing device is fixed on a holster. The induction coil set is configured to be adjacent to the holster. The control unit determines whether a gun is in the holster according to an inductance change between a sensing value generated by the induction coil set and a reference level provided by the reference coil set. In an application of the video-recording system, the control unit transmits a trigger signal to a recording device if the gun is determined to be pulled out of the holster according to the inductance change, so that the recording device is activated to start recording.

Abstract: An electronic device with a connector supporting multiple connection standards includes the connector, a first multiplexer circuit, a processor and a controller. The connector includes a detection pin and at least one signal pin. The first multiplexer circuit is coupled to the at least one signal pin. The processor is coupled to the first multiplexer circuit. The controller monitors the detection pin. The first multiplexer circuit electrically connects the at least one signal pin to the controller. Upon detecting a hot-plug signal occurring at the detection pin, the controller issues a confirmation command via the first multiplexer circuit and the at least one signal pin to request a reply of a device signal. Upon receiving the device signal, the controller controls the first multiplexer circuit according to the device signal to electrically connect the at least one signal pin to the processor or the controller.
