Latest Patents

One of his latest patents is the Environment Difference Detector. This device includes an elastic surface wave element equipped with a substrate that has a surface featuring an annular surface acoustic wave circulating path. It also comprises a surface acoustic wave exciting and receiving unit that excites a surface acoustic wave along the circular path and receives the circulated surface acoustic wave. Additionally, a sensitive film is placed on the circular path to alter its elastic nature based on changes in the surrounding environment. The device includes a speed and intensity measuring unit that assesses the circulating speed and intensity of the surface acoustic wave from the electric signal generated when the unit receives the circulating surface acoustic wave. An environment evaluation unit then evaluates the adjacent environment based on the measured circulating speed and intensity.

Another significant patent is the Light Modulation Device and System. This invention features a light modulation element that consists of three electrodes, a flexible member, and a mirror. The flexible member connects the three electrodes, with the first and second electrodes on one side and the third electrode on the opposite side. The mirror is attached to the flexible member, allowing it to move in response to external electrostatic forces provided by the electrodes. This design enables the mirror to be positioned in a predetermined location based on the state of the flexible member.
