Patent number: 11990667Abstract: An on-vehicle radar apparatus includes a printed circuit board in which at least one radar antenna pattern unit is mounted on a first surface thereof, a case, a cover, and a connector receiving portion. In a situation that a first connector is mounted on the printed circuit board such that a first terminal forms a first angle with respect to a first surface of the printed circuit board, the connector receiving portion receives the first connector to be exposed from the case. In a situation that a second connector is mounted on the printed circuit board such that a second terminal forms a second angle with respect to the first surface of the printed circuit board, the connector receiving portion receives the second connector to be exposed from the case.Type: GrantFiled: August 30, 2021Date of Patent: May 21, 2024Assignee: DENSO CORPORATIONInventors: Satoshi Yamauchi, Yuuya Sugihara

Patent number: 9806534Abstract: A non-contact power feeding apparatus transmits, by at least magnetic coupling, an electric power in a non-contact manner to a power reception coil from a power transmission coil. The transmission coil is electrically connected to an alternating-current power source. The non-contact power feeding apparatus outputs an electric power to a load electrically connected to the power reception coil. The non-contact power feeding apparatus includes a coupling state estimator configured to estimate a coupling state between the power transmission coil and the power reception coil. The non-contact power feeding apparatus also includes an available output power calculator configured to calculate an available output power that can be output to the load, based on a limit value of a circuit element of a power feeding circuit including the power transmission coil and the power reception coil and on the coupling state.Type: GrantFiled: March 5, 2013Date of Patent: October 31, 2017Assignee: NISSAN MOTOR CO., LTD.Inventors: Yuuya Yamauchi, Yuusuke Minagawa, Throngnumchai Kraisorn, Toshihiro Kai
