Abstract: A switch circuit is provided for controlling an IoT device like a lighting device with a wireless module. The switch circuit uses a voltage detector, instead of a current sensing module, for detecting to determine whether to perform corresponding switch operation.

Abstract: System and method for detecting driving behavior include a method including sampling, at a preset time interval, acceleration data of a vehicle generated by an accelerometer along a longitudinal direction of the vehicle. The accelerometer is mounted on the vehicle. The method also includes determining an average acceleration along the longitudinal direction by averaging the sampled acceleration data over a first preset time period. The average acceleration is represented by a magnitude and a direction. The method further includes when the magnitude of the average acceleration is greater than a first preset magnitude, determining an aggressive driving behavior has occurred.

Abstract: The present disclosure provides a smart watch and a gesture input method for the smart watch. The present disclosure starts to acquire data of gestures by receiving gestures of the user, collects the data of the gestures of a user at a continuous time section, and finds proximate text corresponding to the obtained data of the gestures from the prestored corresponding relationship between the data of the gestures and the text, namely the proximate text is final output text. The present disclosure can accurately obtain output text that the user need and meets the user requirement for the smart watch without changing size of a screen of the smart watch.

Abstract: A wearable power supply includes a control module, a battery; and a first charge module, a second charge module, a communication module, and a remaining capacity computation module, which are connected to the control module. The first charge module includes a driver and a first interface used to charge the battery. The driver is connected to the control module, the first interface, and the battery, respectively. The second charge module includes a voltage boost driver and a second interface used to charge a terminal. The voltage boost driver is connected to the control module, the battery, and the second interface, respectively. The voltage boost driver steps up an output voltage of the battery. The remaining capacity computation module adjusts the remaining capacity value of the battery in real time based on the battery discharging curve. The communication module sends the adjusted remaining battery capacity value to the terminal to display.
