Abstract: This application provides a solution for a lock system based on gesture detection. In this solution, the lock system includes an angular acceleration sensor, an acceleration sensor, a processor, a drive motor, and a lock. During the unlocking process, firstly, in response to the movement of the user's hand, the angular acceleration sensor detects a series of angular acceleration values; in response to the movement of the user's hand, the acceleration sensor detects a series of acceleration values. Then, the processor receives a series of angular acceleration values and a series of acceleration values; the processor converts the received series of angular acceleration values and a series of acceleration values into a first data sequence and a second data sequence respectively; the processor converts the first data sequence and the second data sequence. The data sequence is combined into a third data sequence.

Abstract: This application provides a breathing amplitude detection solution based on micro force detection. In this solution, the breathing amplitude detection system includes a sensor, a processor, a sensor power supply circuit, an operational amplifier, and a feedback resistor. The sensor is a micro force detection sensor. The sensor can be connected to a user and sense the amplitude of the user's breathing movements. The sensor supply circuit is connected to the first terminal of the sensor and provides a reference voltage to the sensor. The second terminal of the sensor and the first terminal of the feedback resistor are connected to the first input terminal of the operational amplifier. The second terminal of the feedback resistor is connected to the output of the operational amplifier. The output of the operational amplifier is connected to the processor to transmit the measured voltage. The processor maps the measured voltages to discrete voltage values.
