Kosuke Shamoto has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).
Abstract: The encoder includes a plurality of position-detection-signal generation systems that generates electrical signals as position detection signals having different cycles, respectively; a first computing unit that calculates first position data based on the position detection signals generated by the position-detection-signal generation systems; a second computing unit that calculates second position data based on electrical signals generated by fewer ones of the position-detection-signal generation systems than in the first computing unit; and a failure determination unit that determines whether the encoder is defective based on a comparison between the first position data and the second position data.
