The distance of device calculates the distance between first reflection point and second reflection point.
8. the terminal operating status control device as described in any one of claim 5 to 7, which is characterized in that the terminal work
Make behavior control device further include:
Mode selection module, for controlling the terminal and entering human testing mode every the second preset time period；
Control module is specifically used for, and in the terminal in the case where entering human testing mode, controls preset supersonic generator and exists
Ultrasonic wave is issued in presetting range；
The processing module is also used to when there are when human body, exit the human testing mode in the presetting range.
