Latest Patents

One of his latest patents is a method and device for measuring eye refraction errors. This invention involves projecting a plurality of infrared patterns onto the eye being measured. The reflected light is directed onto light-sensitive detectors, and the outputs are processed through bandpass filters, an automatic gain control circuit, and an A/D converter to a microprocessor. The microprocessor analyzes the digitized outputs to calculate refraction powers using a disclosed nonlinear regression technique. This method allows for precise calculation of refraction errors and includes a reliability coefficient.

Another notable patent is a device for detecting blinking of an eye under examination. This ophthalmological instrument features a blinking detecting device that accurately identifies when an eye blinks. This capability eliminates errors in optical measurements caused by variations in signal light due to blinking. The optical system captures light beams reflected from the eye to form an image, which is processed by an image pickup element that generates a video signal. A detecting circuit then determines if the video signal exceeds a predetermined threshold, indicating that blinking has occurred.
