He has made significant contributions to the field of technology, particularly in the area of inspection apparatuses and light field measurement methods. With a total of 2 patents, Mima's work showcases his innovative spirit and technical expertise.
Latest Patents
One of Mima's latest patents is an "Apparatus for inspecting bottles having elliptic light converging means." This invention is designed to detect flaws or contamination in bottles by utilizing a light converging function performed by an open-sided elliptic cylinder with a reflective inner surface. The inspection point of the bottle is positioned at one of the two foci of the cylinder, while a light receiving element is located at the other focus. If any defects are present, the light is reflected irregularly, allowing the system to effectively detect the issue through the output of the light receiving element.
Another significant patent is the "Method and apparatus for measuring the distribution of a light field." This invention quantizes a video signal produced by capturing the light image projected onto a screen. It employs a series of voltage comparators to create a dark and bright stripe signal, which is then displayed on a video device to form a radially discrete annular pattern representing equibrightness curves.
