Publication number: 20240069187Abstract: An observation allocating section exclusively allocates an observation point to each existing tracker in accordance with a distance between observation information acquired by an information acquiring section and observation information indicated by a predictive distribution. A hypothesis generating section generates a hypothesis likelihood and a hypothesis distribution, for each target tracker and for each hypothesis belonging to a hypothesis group including a first hypothesis and a second hypothesis. The first hypothesis is a hypothesis that the observation point is a result of observation of a subject target. The second hypothesis is a hypothesis that the observation point is not a result of observation of the subject target. The hypothesis likelihood is the likelihood of the hypothesis. The hypothesis distribution is the state distribution updated on the assumption that the hypothesis is correct.Type: ApplicationFiled: November 9, 2023Publication date: February 29, 2024Inventors: Tetsuya KUSUMOTO, Shingo SHIMIZU, Takashi OGAWA, Masaki YONEDA

Patent number: 11425679Abstract: In a terminal position estimation system, a terminal position estimation apparatus, or a terminal position estimation method, an electric wave is received by a reception antenna of a communication terminal and is transmitted from multiple transmission antennas. A communication terminal position is estimated based on a magnetic field strength of the electric wave. When the communication terminal position is estimated, a position satisfying an approximate expression is estimated as the communication terminal position. The approximate expression shows a magnetic field strength distribution and is expressed by two variables of a distance from the multiple transmission antennas to the communication terminal and an angle between an axial direction of the multiple transmission antennas and a direction in which the communication terminal is positioned.Type: GrantFiled: December 8, 2020Date of Patent: August 23, 2022Assignee: DENSO CORPORATIONInventors: Tetsuya Kusumoto, Takashi Saitou, Takashi Shinoda
