Patent number: 11967294Abstract: A common electrode driver includes an inverting amplifier including a first resistor, a second resistor, and an operational amplifier, and a resistance ratio adjustment circuit that adjusts, in accordance with a length of one horizontal scan period, a resistance ratio being a ratio of a resistance value of the second resistor to a resistance value of the first resistor. A feedback voltage is provided to one end of the first resistor. The resistance ratio adjustment circuit sets the resistance ratio when second driving is performed, in which a length of one horizontal scan period is a second time longer than a first time, to be smaller than the resistance ratio when first driving is performed, in which a length of one horizontal scan period is the first time.Type: GrantFiled: May 1, 2023Date of Patent: April 23, 2024Assignee: Sharp Display Technology CorporationInventors: Masaki Uehata, Yasuki Mori, Kohji Saitoh, Takayuki Mizunaga, Kazuya Kondoh, Takashi Nojima, Kazuhisa Yoshimoto, Kosuke Kawamoto, Hiroyuki Kito, Kazuki Nakamichi

Patent number: 11536063Abstract: A door control device stops a door such that the door does not come into contact with an obstacle existing in a rotation range of the door. The door control device includes: a distance calculation unit configured to calculate a distance from the door to the obstacle; a speed calculation unit configured to calculate an actual speed of the door; a braking force setting unit configured to set a braking condition indicating transition of a braking force applied to the door; a speed estimation unit configured to estimate transition of an estimated speed of the door from start of braking until the door stops; and a braking force correction unit configured, during braking, to correct a braking force such that the braking force is increased, or reduced, when a time gradient of the actual speed is gentler than, or steeper than, that of the estimated speed.Type: GrantFiled: November 7, 2019Date of Patent: December 27, 2022Assignee: AISIN CORPORATIONInventors: Ryu Miyashiro, Kosuke Kito

Publication number: 20200224476Abstract: A vehicle door device includes: a braking control unit applying a braking force to a swing door of a vehicle by controlling an operation of a braking device; an action position detection unit detecting an action position of the swing door; and a vertical displacement detection unit detecting a vertical displacement of the swing door. The braking control unit does not execute braking control in a case where the action position of the swing door changes with the vertical displacement exceeding a predetermined gripping operation determination value, even in a case where an execution condition of braking control for applying the braking force is satisfied.Type: ApplicationFiled: January 7, 2020Publication date: July 16, 2020Applicant: AISIN SEIKI KABUSHIKI KAISHAInventor: Kosuke KITO
