Masayoshi Sueya 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).

  • Radar device
    Patent number: 7486225
    Abstract: A data code generator produces a data code, while a reference code generator produces a reference code. The data code is phase-shifted by the data code generator in a predetermined sweep range, according to a sweep command signal given by a phase difference detector. The phase difference detector compares the phase of the data code with that of the reference code to obtain phase difference data. Based on the phase difference data, a correction signal generator produces a correction signal to keep the data code in phase with the reference, code. The phase setter optimizes the phase of the data code according to the correction signal.

  • Method and apparatus for processing information, and computer product
    Publication number: 20070025555
    Abstract: A sound-signal generating unit generates, when a positional relationship between a local information processing apparatus and a user is acquired, a sound signal that makes the user perceive a virtual sound source at a predetermined position in a three-dimensional space based on the acquired positional relationship.

  • Data code transmission device
    Publication number: 20050111569
    Abstract: A data code transmission device that detects and corrects phase differences between serial data codes to ensure the quality of data transmission. A data code generator produces a data code, while a reference code generator produces a reference code. The data code is phase-shifted by the data code generator in a predetermined sweep range, according to a sweep command signal given by a phase difference detector. The phase difference detector compares the phase of the data code with that of the reference code to obtain phase difference data. Based on the phase difference data, a correction signal generator produces a correction signal to keep the data code in phase with the reference code. The phase setter optimizes the phase of the data code according to the correction signal.
