Latest Patents

Among his latest innovations is a radio receiver device. This device includes a radio signal processing section and a digital processing section. The radio signal processing section converts a received radio signal into a digital signal, demodulates the digital signal, and detects the S/N ratio of the radio signal. The digital processing section digitally processes digital signals and switches its operation mode based on the detected S/N ratio, thereby controlling digital noise generated in the digital processing. Additionally, the radio processing section checks whether the S/N ratio is lowered by digital noise or external shielding. The digital processing section only switches its operation mode to reduce digital noise when the cause of the fall in the S/N ratio is identified as digital noise.

Another significant patent is a navigation system designed for vehicles. This system receives a GPS signal that provides GPS time data, which rolls over at an interval of 19.7 years, starting from 0 a.m. on January 6th, 1980. The system acquires map generation date information from a map database, utilizing both the GPS time data and the map data generation time information to calculate an accurate current date and time.
