US Patent Issued to INSTITUTE OF SCIENCE TOKYO on June 23 for "Phase modulation signal generating device for fiber-optic gyroscope" (Japanese Inventors)

ALEXANDRIA, Va., July 15 -- United States Patent no. 12,663,266, issued on June 23, was assigned to INSTITUTE OF SCIENCE TOKYO (Tokyo).

"Phase modulation signal generating device for fiber-optic gyroscope" was invented by Martin Santiago Miranda (Tokyo), Nobuyuki Takei (Tokyo), Yuki Miyazawa (Tokyo) and Mikio Kozuma (Tokyo).

According to the abstract* released by the U.S. Patent & Trademark Office: "A phase modulation signal generating device for a fiber-optic gyroscope includes a sine wave generating part and a superimposing part. The sine wave generating part generates a fundamental sine wave of an odd-order frequency (v=(2n+1)ve, where n=0, 1, 2.. ) of the eigenfrequency (ve) of the fiber-optic coil and a higher-order sine wave of an o...
