Patent number: 5926164Abstract: An infrared-spectrum image processor mounted in a vehicle assists a driver in seeing under difficult conditions, such as rain, smog or fog. The device operates, in part, on the principle that infrared rays are "visible" at longer distances than are light rays falling within the visible spectrum, especially when adverse visual conditions exist. Also, different objects have different images when "viewed" in the infrared spectrum. Thus, even if an image is difficult to see in the visible spectrum, if the infrared spectrum is not disturbed, it may be possible to "see" the objects anyway. In operation, the processor analyzes a histogram derived from a taken image. If the histogram shows a distribution containing two peaks, the processor determines that there is an obscure image. For mounting on a vehicle an infrared camera is mounted on the vehicle roof. A dash-mounted display is provided for transmitting the processed images to the driver to facilitate decision-making while driving.Type: GrantFiled: November 18, 1996Date of Patent: July 20, 1999Assignees: Aisin Seiki Kabushiki Kaisha, Kabushiki Kaisha ShinsangyokaihatsuInventors: Tomomitsu Terakawa, Yoshihiro Naruse, Takeshi Ikeyama

Patent number: 5918280Abstract: Angular rate sensor comprises a x-direction oscillator, a x-oscillation driver, a z-oscillation sensing element for detecting an angular rate and an additional z-oscillation driver for triggering a free damped oscillation of the oscillator in the z-direction. An electric sensing circuit energizes the z-oscillation driver for triggering the free damped oscillation and detects the frequency of the free damped oscillation. The frequency is the resonant frequency of the oscillator. Thereafter the electric sensing circuit energizes the x-oscillation driver with the detected frequency for detecting the angular rate.Type: GrantFiled: July 29, 1997Date of Patent: June 29, 1999Assignee: Aisin Seiki Kabushiki KaishaInventors: Lin Gang, Yoshihiro Naruse, Takahiro Yamada
