Publication number: 20230192155Abstract: An electric vehicle control device includes an idling-sliding control unit that provides control to reduce or prevent idling and sliding that may occur on a wheel of an electric vehicle. The idling-sliding control unit includes an idling-sliding detection unit for detecting idling or sliding that has occurred on the electric vehicle, and a torque command value generation unit that generates a torque command value used for reducing or preventing idling or sliding, based on output of the idling-sliding detection unit. When a prediction signal representing an anticipated occurrence of idling or sliding is inputted, the torque command value generation unit performs narrowing of the torque command value regardless of whether or not the idling-sliding control unit is performing idling-sliding control.Type: ApplicationFiled: May 29, 2020Publication date: June 22, 2023Applicant: Mitsubishi Electric CorporationInventors: Yoshinori YAMASHITA, Osamu ARAI, Takashi MAEDA, Tatsuro TAKAHASHI

Patent number: 10405827Abstract: A three-dimensional reference image is displayed along with an ultrasound image (tomogram). The three-dimensional reference image has a first existing line representing a first puncture needle and a second prospective line indicating the prospective puncture path of a second puncture needle. The position and orientation of the probe are adjusted by the user with reference to the three-dimensional reference image so that the second prospective line has an appropriate position relative to the first existing line. After the adjustment, the second puncture needle is inserted into the body using a puncture adaptor provided on the probe. A second existing line is displayed in the three-dimensional reference image when the insertion of the second puncture needle is completed.Type: GrantFiled: May 11, 2015Date of Patent: September 10, 2019Assignee: HITACHI, LTD.Inventors: Osamu Arai, Naoyuki Murayama
