Publication number: 20120262394Abstract: A touch operation unit has a manipulated surface accepting a touch operation. An operation detection unit detects a touch operation on the manipulated surface. A moving unit moves the touch operation unit. A movement control unit drives the moving unit to control a movement of the touch operation unit, when the operation detection unit detects a touch operation, to satisfy a predetermined stimulable condition enabling stimulation of a skin sensory receptor. The stimulable condition is a condition of a movement quantity of the touch operation unit and a moving speed of the touch operation unit or a condition of the movement quantity of the touch operation unit and an acceleration of the touch operation unit.Type: ApplicationFiled: April 10, 2012Publication date: October 18, 2012Applicants: Denso Corporation, Nippon Soken, Inc.Inventors: Norio Sanma, Kunihiro Nakagawa, Koji Tamai

Patent number: 8290066Abstract: A signal transmission circuit is capable of reducing distortion that occurs during signal transmission. A digital output signal is transmitted from a terminal to a signal line via an output buffer circuit and an output impedance unit. The terminal is connected to an impedance variation unit via an impedance control unit. The impedance variation unit designates an impedance for terminating the signal line when the output data is changed from a high level H to a low level. A reflection occurring on the signal line can be prevented and a waveform distortion can be suppressed.Type: GrantFiled: May 7, 2009Date of Patent: October 16, 2012Assignees: Nippon Soken, Inc., DENSO CORPORATIONInventors: Hiroyuki Mori, Norio Sanma, Yoshihiko Ozeki, Kazuyoshi Nagase

Publication number: 20120143456Abstract: A driving assistance apparatus mounted to a vehicle is disclosed. The apparatus determines whether an amount of change in tire wheel speed of each tire wheel of the vehicle exceeds a threshold. The apparatus specifies a tire wheel crossing order, which is an order in which the tire wheels of the vehicle cross over a level difference between a road and a parking lot when the vehicle crosses over the level difference. The apparatus determines whether or not the vehicle has crossed over the level difference between the road and the parking lot, based on whether a threshold-exceeding order is identical to the specified tire wheel crossing order. The threshold-exceeding order is an order in which the amounts of change in the tire wheel speed of the respective tire wheels exceed the threshold.Type: ApplicationFiled: November 29, 2011Publication date: June 7, 2012Applicants: DENSO CORPORATION, NIPPON SOKEN, INC.Inventors: Yusuke UEDA, Motonori TOMINAGA, Norio SANMA, Tatsuru KUWABARA, Hirotane IKEDA

Patent number: 7863891Abstract: A collision detection device is provided with a coil which is arranged at an inner side of an outer panel of a body portion of a vehicle and faces the outer panel to generate a magnetic field in a direction toward the outer panel, and a collision determining unit for determining a collision with the body portion of the vehicle based on a variation of an inductance of the coil. The collision determining unit includes a resonance circuit which is constructed of the coil. When there occurs a collision with the vehicle body portion, a distance between the outer panel and the coil will decrease so that an inductance of the coil can instantly decrease. Therefore, a resonance frequency of the resonance circuit will increase and be detected, thus shortening the response time.Type: GrantFiled: April 24, 2007Date of Patent: January 4, 2011Assignees: Denso Corporation, Nippon Soken, Inc.Inventors: Masanori Kawaura, Norio Sanma, Kyoujirou Suzuki, Sadayuki Kuwahara, Shinichi Kiribayashi
