Introduction

Tetsuya Kusumoto is a prominent inventor based in Nisshin, Japan. He has made significant contributions to the field of position estimation technologies, holding a total of 8 patents. His work focuses on systems that enhance the accuracy of position estimation for communication terminals and portable devices.

Latest Patents

Kusumoto's latest patents include a terminal position estimation system, terminal position estimation apparatus, terminal position estimation method, and a computer-readable non-transitory tangible storage medium storing a control program. In these innovations, an electric wave is received by a reception antenna of a communication terminal and is transmitted from multiple transmission antennas. The position of the communication terminal is estimated based on the magnetic field strength of the electric wave. The estimated position satisfies an approximate expression that shows a magnetic field strength distribution, expressed by two variables: the distance from the multiple transmission antennas to the communication terminal and the angle between the axial direction of the antennas and the direction of the communication terminal.

Another notable patent is the portable device position estimation system. This system includes a vehicle-mounted transceiver and intercept devices. The vehicle-mounted system determines the propagation time of a wireless signal from the transceiver to a portable device, based on the round trip time. It also calculates the propagation time from the portable device to the intercept device, enhancing the overall accuracy of position estimation.
