Patent number: 11914082Abstract: A ranging device includes transducers, a transmission circuit, a reception circuit, a transfer data generation circuit, and a transfer circuit. The transmission circuit causes the transducers to transmit transmission waves. The reception circuit outputs a received signal obtained by digitizing a reflected wave of the transmission wave with a sampling frequency equal to or more than a frequency of the transmission wave. The generation circuit separates, into a target period and a non-target period, time-series received signals. The target period is a period in which a wave height is equal to or more than a threshold. The non-target period is a period in which a wave height is less than the threshold. The generation circuit performs thinning-out processing on received signals in the non-target period and generates waveform information indicating a waveform received by the transducer. The transfer circuit outputs the waveform information.Type: GrantFiled: November 22, 2022Date of Patent: February 27, 2024Assignee: Panasonic Intellectual Property Management Co., Ltd.Inventors: Takuya Iwamoto, Tadashi Morita

Patent number: 11859588Abstract: In an internal combustion engine, fuel injection is stopped to automatically stop the engine when automatic stop conditions are met. When there is a request to restart the engine while an engine speed is decreasing due to automatic stoppage, the engine is started by resuming fuel injection if the engine speed is equal to or greater than a combustion recoverable rotational speed threshold, at which restarting is possible only by fuel injection. When there is a request to restart the engine while an engine speed is decreasing due to automatic stoppage, the engine is started using a starter motor if the engine speed is less than the combustion recoverable rotational speed threshold. When there is a request to restart the engine in a brake ON state, the engine is not started by resuming fuel injection, but rotated and started using the starter motor.Type: GrantFiled: September 24, 2020Date of Patent: January 2, 2024Assignee: Nissan Motor Co., Ltd.Inventors: Shouta Hamane, Tadashi Iwamoto

Patent number: 11788482Abstract: In an internal combustion engine, fuel injection is stopped to automatically stop the engine when automatic stop conditions are met. The engine is started in response to a request to restart the engine while an engine speed is decreasing due to an automatic stoppage by resuming fuel injection if the engine speed is equal to or greater than a combustion recoverable rotational speed threshold, and by using an electric motor if the engine speed is less than the combustion recoverable rotational speed threshold. When the engine speed of the internal combustion engine falls below the combustion recoverable rotational speed threshold while the engine speed is decreasing due to an automatic stoppage, an amount of air entering cylinders is reduced to be less than before the engine speed fell below the combustion recoverable rotational speed threshold.Type: GrantFiled: September 16, 2020Date of Patent: October 17, 2023Assignee: Nissan Motor Co., Ltd.Inventors: Shouta Hamane, Tadashi Iwamoto
