(when electronic equipment is for notebook computer, the controller 50 can be notes to the controller 50 of variodenser 70 and electronic equipment
The embedded controller of this computer, the English abbreviation of embedded controller is：EC) electrically connect, and the variable condenser 70 includes
First pole piece 31 and the second pole piece 32, the first pole piece 31 and the second pole piece 32 be oppositely arranged and can be relative rotation；First turn
Axle 10 is used for driving the first pole piece 31 to rotate to change the overlapping area of the first pole piece 31 and the second pole piece 32, variable condenser 70
Different capacitances are exported from the second pole piece 32 different overlapping area by the first pole piece 31 so that the capacitance of output with
The rotational angle (display end is with respect to the open angle of system end in other words) of first rotating shaft 10 sets up corresponding relation；Controller 50
For capacitance is obtained, and finally determine the open angle of display end.
For example, the storage value (or memory range) that can be stored with corresponding from different capacitances in controller 50, so that
The opening angle angle value of the corresponding display end of each storage value (or memory range), controller 50 is by produced by variable condenser 70
Electric capacity be compared and logical calculated with storage value (or memory range), so that it is determined that storage value corresponding to capacitance (or
