Patents by Inventor Tetsuya Mabuchi

Tetsuya Mabuchi 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).

AZIMUTH PROCESSING DEVICE, AZIMUTH PROCESSING METHOD, AZIMUTH PROCESSING PROGRAM, DIRECTION FINDING DEVICE, TILT OFFSET CORRECTING METHOD, AZIMUTH MEASURING METHOD, COMPASS SENSOR UNIT, AND PORTABLE ELECTRONIC DEVICE

Publication number: 20120072114

Abstract: An azimuth processing device is designed for outputting azimuth data based on measurement data sequentially output from a compass sensor. In the device, an accumulation section selectively accumulates substantially new pieces of the measurement data. An offset data updating section updates offset data of the compass sensor based on plural pieces of the measurement data accumulated by said accumulation section. An azimuth data output section outputs the azimuth data based on substantially newest measurement data and the offset data.
