Patent number: 5214737Abstract: An actuator includes a closed space defined by a deformable member in which an amount of thermally expansible gas is filled. In the closed space, there is also a substance which changes the light into the heat. A control device is set to establish the supply of the light into the closed space. Upon turning-on of the control device, the substance changes the supplied light into the heat, resulting in that the resultant heat brings the expansion of the gas. Thus, the member is brought into deformed condition. The deformation can be used as a force for operating a specific element.Type: GrantFiled: September 25, 1991Date of Patent: May 25, 1993Assignee: Aisin Seiki KabushikiInventors: Naomasa Nakajima, Yoshihiro Naruse, Mitsuhiro Ando, Tomokimi Mizuno

Patent number: 4768088Abstract: An apparatus controls an on/off condition of an electrical device or devices mounted on an automobile, such as a car radio set, an air conditioner, a cigar lighter or the like. The face of a driver who is mounted on the vehicle is photographed by a television camera, which produces a video signal that is subject to a digital processing operation for storage in a frame memory. A video signal processing system essentially comprising CPU, RAM and ROM is operative, based upon the video data stored in the frame memory, to detect the pupil and mouth of the driver as well as their locations and configurations. A change in the location of the pupil as well as a change in the configuration of the pupil and the mouth is detected as a time sequence, and an on/off command signal is supplied to an electrical device in accordance with such changes.Type: GrantFiled: December 2, 1986Date of Patent: August 30, 1988Assignee: Aisin Seiki KabushikikaishaInventor: Mitsuhiro Ando
