Latest Patents
One of his latest patents is a vehicle seat incorporated with an occupant sensor. This invention features a central support member that typically consists of wire mesh or grid, supporting most of the load of the vehicle occupant via spring members. The design allows for a relatively large displacement when the occupant is seated, enabling the detection of displacements in various parts of the central support member. This technology evaluates the magnitude and distribution of the load reliably and accurately. Additionally, the displacement sensors used are inexpensive and easy to handle, ensuring they do not interfere with existing seat designs or equipment such as seat heaters.
Another significant patent is the authenticity identifying system for information storage cards. This system aims to prevent unauthorized duplication of information storage cards, including magnetic cards, IC cards, and optical cards. The card features an identification region identifiable by a simple optical sensor. This region may consist of holographs, diffraction gratings, and other processed surfaces with specific reflective or transmissive directivities. The identification region comprises multiple segments with varying reflective or transmissive properties, allowing simultaneous access by the optical sensor.
