Title: Shigeru Imafuku: Innovator in Mobile Positioning Technology
Introduction
Shigeru Imafuku is a notable inventor based in Nagano, Japan. He has made significant contributions to the field of mobile positioning technology, holding a total of 5 patents. His work focuses on improving the accuracy and reliability of location determination for mobile units.
Latest Patents
Imafuku's latest patents include a "Halt continuation determination method and halt continuation determination device." This invention involves intermittently measuring the location of a mobile unit based on GPS satellite signals. A halt start time zone is established based on the measured location when the determination begins. The time zones are updated through statistical processing of past location measurements. The device determines whether the mobile unit remains in a halt state by checking if the newly measured location falls within the set halt determination regions.
Another significant patent is the "Position calculating method and position calculating device." This method is performed by a device equipped with a sensor unit that moves with the mobile body. It calculates the position of the mobile body while setting a detection value agreement range for various movement possibilities. The method employs fuzzy inference calculations to determine if the mobile body is in a stopping condition and adjusts the error parameters used in the Kalman filter process accordingly.
