With a total of 17 patents to his name, his work continues to influence advancements in various applications.

Latest Patents

One of his latest patents is a position detecting device of an aperture module. This device is designed to detect the position of a magnet that moves between two target points. It includes a first hall device that generates a first hall voltage and a second hall device that generates a second hall voltage. The device also features a subtractor for generating a subtraction voltage based on the difference between the two hall voltages, an adder for generating an addition voltage, and a divider for calculating the ratio of the subtraction voltage to the addition voltage. Additionally, it has a subtraction voltage changing unit that maintains the subtraction voltage constant at both target points and during transitions.

Another notable patent is the control circuit and camera iris driving device. This controller includes a signal processing circuit that generates a detected position value corresponding to the current position of the iris. It utilizes first and second sensing signals from position sensors to detect the aperture position. The control circuit divides the section between the first and second aperture positions into multiple control sections. When a command to change the aperture is issued, the controller performs control operations for each section based on the detected position value. A driving circuit generates a driving current to control the iris movement.
