Latest Patents

Inoue's latest patents include a wireless distance measurement system and a wireless distance measurement method. The wireless distance measurement system allows for the measurement of distance between a base station and a terminal without requiring clock synchronization between multiple base stations. This innovative approach eliminates the need for input of the position relationships between the base stations. The system utilizes a clock phase shift section that shifts the clock used to generate transmission pulses by a specific amount every 100 nanoseconds. Additionally, the A/D conversion section converts signals re-radiated from the terminal into digital signals using the shifted clock. The correlation calculation section performs calculations to create a delay profile, while the incoming wave detection section identifies peaks of the pulses in the delay profile. Finally, the distance calculation section computes the distance to the terminal based on the timings of pulse transmission and peak detection.

Another notable patent is the wireless device and wireless channel measurement controller. This invention addresses the measurement of wireless channels in an IEEE 802.11 wireless local area network (WLAN). In regions like North America, where eight wireless channels are available, the measurement process is optimized. The algorithm first measures odd-numbered channels and, in the event of radio interference in channel Ch5, measures the adjacent channels Ch4 and Ch6. This method significantly reduces the measurement time from eight channels to six channels.
