Latest Patents

One of his latest patents is an offset correcting circuit for an encoder. This invention is capable of detecting a correct offset value even when a sampling period is long, as in the case of a low-speed A/D converter. It effectively restrains the influence of noise, ensuring precise angle signal output based on digital signals obtained from A/D conversions of two signals with a phase difference of about 90 degrees. The circuit includes an offset detecting circuit that obtains an offset value of one signal when the other signal's A/D converted value is zero or close to zero. Additionally, it features a compensating circuit that uses the detected offset value to correct the signal.

Another significant patent is the encoder interpolation circuit, which corrects the interpolation angle between received sine-wave and cosine-wave encoder signals. This circuit is designed to obtain interpolation data within one wave from two sine-wave encoder signals of different phases. It comprises several components, including interpolative computation means, signal deviation detecting means, correction data forming means, and corrective computation means. Together, these elements work to ensure accurate and corrected interpolation data.
