Patent number: 8345096Abstract: The disclosed subject matter relates to a sensor and apparatus for vehicle height and slant measurement which can include a light source, and two cameras with respective lenses. The light source can be configured to emit light towards a road, and both cameras can be configured to receive the image of the road that is illuminated by the light from the light source and to thereby create image data. The apparatus can include a control circuit that can geometrically measure a vehicle height in accordance with the image data. The sensor can also receive image data from different points and from two light sources, and the apparatus can detect a vehicular lean using the different vehicle heights. Thus, because the sensors of the disclosed subject matter do not necessarily include a moving part as in the conventional sensor, the sensors can be easily attached to a vehicle body and can also be used for a vehicular lean detection.Type: GrantFiled: May 7, 2009Date of Patent: January 1, 2013Assignee: Stanley Electric Co., Ltd.Inventors: Yutaka Ishiyama, Takuya Kushimoto

Patent number: 8093613Abstract: Whereas incandescent light bulbs and other similar light sources known in the related art emit light in all directions, LED lamps can emit light in a single direction, and this is manifested in the problem of being unable to achieve light distribution characteristics satisfied by conventional headlamp designs. In accordance with an embodiment of the presently disclosed subject matter, an LED lamp for a light source of a headlamp can include an LED chip in the vicinity of the focus of a projection means and a shielding member covering a portion of the LED chip in a formation allowing a light distribution characteristic suitable for a vehicle front-illumination light to be obtained when light from the LED chip is magnified and projected in an illumination direction by a projection lens or the like constituting the projection means. Accordingly, accurate light distribution characteristics can be obtained in a simple manner by projecting in the illumination direction using the projection lens.Type: GrantFiled: November 23, 2009Date of Patent: January 10, 2012Assignee: Stanley Electric Co., Ltd.Inventors: Yasushi Yatsuda, Takashi Ebisutani, Teruo Koike, Takuya Kushimoto, Ryotaro Owada, Masafumi Ohno, Takashi Futami

Publication number: 20090295906Abstract: A car side-view camera has, on the side of a car, a side turn lamp housing containing a compound-eye imaging device and a near-infrared lamp forming the camera. The compound-eye imaging device has 6 imaging units in 2 rows 3 columns. Three imaging units in one row are provided with an infrared cut filter. The imaging units in left and right columns are provided with rectangular prisms to shift light entrance zones left and right. The microprocessor sets the near-infrared lamp in off-state for image capture during the day to combine 3 unit images by the imaging units with the infrared cut filter into a panoramic image, and switches the near-infrared lamp to on-state for image capture at night to combine 3 unit images by the imaging units without the infrared cut filter into a panoramic image. This camera can stably obtain a clear image regardless of day or night.Type: ApplicationFiled: May 27, 2009Publication date: December 3, 2009Applicant: Funai Electric Co., Ltd.Inventors: Takuya Kushimoto, Yutaka Ishiyama, Takashi Toyoda, Yoshizumi Nakao, Yasuo Masaki

Publication number: 20080247184Abstract: A conventional keyless entry system uses a radio wave as an unlocking or locking signal and is therefore substantially non-directional. For example, when an unlocking operation is performed, keys of all doors are unlocked, so that for example in a vehicle having a certain slide door or a kick-up door, an occupant of the vehicle may forget to lock the door. According to the presently disclosed subject matter a keyless entry system for locking and unlocking lock(s) of a vehicle can include an infrared light projector having a narrow radiation angle, and a light receiving/emitting unit corresponding to operating conditions of keys/locks. The light receiving/emitting unit can include a combination of a light receiving element for receiving the infrared light and a light emitting element for indicating the position of a key/lock which is operated correspondingly to the infrared light received by the light receiving element.Type: ApplicationFiled: March 26, 2008Publication date: October 9, 2008Inventors: Yoshiyuki Matsumoto, Hiroshi Uematsu, Takuya Kushimoto, Yutaka Ishiyama
