Patent
Light irradiating apparatus having light emitting diode used as light source
Yukio Ohmamyuda,Shigeru Kimura,Toru Tanabe,Kazuhisa Iwasaki,Takao Seto,Hideki Kitamura,Kazuhiko Sugimura,Yasushi Senoo +7 more
TL;DR: In this article, a light source constituted by a plurality of light emitting units which are arranged opposite to a light irradiating lens such that light emission from a part of the light source is changed to light emissions from the whole surface of the source and vice versa is disclosed.
Patent
Apparatus and method of warning rear-end collision
Yukio Ohmamyuda,Hideki Kitamura,Yasushi Senoo,Shigeru Kimura,Toru Tanabe,Kazuhisa Iwasaki,Takao Seto +6 more
TL;DR: In this paper, the authors proposed a warning system for possible rear-end collision of a vehicle with another vehicle preceding it using a computer, a distance sensor, and a velocity sensor.
Patent
Optical distance measuring apparatus
Yukio Ohmamyuda,Shigeru Kimura,Toru Tanabe,Kazuhisa Iwasaki,Takao Seto,Hideki Kitamura,Kazuhiko Sugimura,Yasushi Senoo +7 more
TL;DR: In this paper, a two-eyed optical distance measuring device is described, where a light source is disposed in a housing on the light emitting side to emit a modulated distance measuring light beam therefrom toward the object to be measured, and an iris mechanism is disposed on the incident side of the optical fiber to variably adjust an optical quantity of the reference light beam.
Patent
Vehicular optical-radar apparatus
Yukio Omamyuda,Shigeru Kimura,Toru Tanabe,Kazuhisa Iwasaki,Takao Seto,Hideki Kitamura,Kazuhiko Sugimura,Yasushi Senoo +7 more
TL;DR: In this article, a vehicular optical radar system comprising a light emitting portion for irradiating a signal light on an object ahead and a light receiving portion for receiving a reflecting light from the object is described.
Patent
Optical distance measuring apparatus and apparatus for mounting the same
Yukio Omamyuda,Shigeru Kimura,Toru Tanabe,Kazuhisa Iwasaki,Takao Seto,Hideki Kitamura,Kazuhiko Sugimura,Yasushi Senoo +7 more
TL;DR: In this paper, an optical distance measuring apparatus with a light emitting portion serving as a light source to emit a distance measuring light beam, an optical lens system, a light receiving portion for receiving a reflected light reflected from the vehicle running ahead of his vehicle through the optical lens, and a processing system for correcting phase delay between the distance measuring the light beam and the reflected light beam utilizing reference light beams emitted from a plurality of reference light sources.
