  • Patent number: 9977651
    Abstract: The present disclosure discloses an image processing method of a mobile terminal, and a mobile terminal. To process an image, an audio signal is collected using a sensor of the mobile terminal. Air-blowing signal intensity is acquired by performing a windowed fast Fourier transform (FFT) on the audio signal to obtain a frequency domain signal of the audio signal. The frequency domain signal of the audio signal is divided into at least one time-slice frequency domain signal. It is then identified whether the audio signal is an air-blowing signal according to the at least one time-slice frequency domain signal and a preset property of the air-blowing signal. The air-blowing signal intensity is acquired according to the at least one time-slice frequency domain signal when the audio signal is identified as an air-blowing signal. An image is acquired according to the air-blowing signal intensity.

  • Patent number: 8007740
    Abstract: The invention discloses a reaction cuvette wash unit comprising a cleaning needle assembly, a straight guide pair, a slide screw pair, a motor, a trigger component associated with a cleaning needle of the cleaning needle assembly in a manner to move with that cleaning needle, and a sensor used to sense the position of the trigger component. When the trigger component moves to a predetermined position, the sensor is triggered and sends a signal to a controller such that the controller controls in a manner to stop the motor. Each of cleaning needle components further comprises a sheath holder and an elastic member. The elastic member is designed to provide an elastic contact while the cleaning needles touch the bottom surface of the reaction cuvette, such that a relatively small force is exerted upon the bottom of the reaction cuvette, thereby effectively protecting the reaction cuvette from damage.
