Latest Patents

One of Nakajima's latest patents is an "Apparatus and method for measuring resonance frequency of electric circuit." This invention provides a method and apparatus for measuring the resonance frequency of an electric circuit with low disturbance and high accuracy. It utilizes an electrooptic crystal, which changes its refractive index based on the strength of an applied electric field, as a sensor. A frequency-sweep electromagnetic wave is applied to the resonance section of the electric circuit from an external device. The induced current flowing in the resonance section generates an electric field, which is detected by measuring the refractive index of the electrooptic crystal through the relevant light intensity. The resonance frequency is determined based on the maximum electric field strength.

Another significant patent is the "Display and image capture apparatus which enables eye contact." This invention is designed for videophones or video teleconferencing systems. It features a half-transparent mirror array positioned adjacent to the display surface. The image reflected by this array is captured by a video camera. The half-transparent mirror array consists of multiple micro half-mirrors arranged in the same plane at a predetermined inclination angle, reflecting incident light from a subject toward the video camera.
