Abstract: An automotive occupant position restraint apparatus senses a position of an occupant of a motor vehicle. An optical energy source emits optical energy that is substantially limited to a first range of wavelengths that corresponds to an atmospheric absorption peak. An optical energy receiver receives the optical energy emitted by the optical energy source after the optical energy has been reflected within a passenger compartment of the motor vehicle. A range of wavelengths that the receiver is operable to receive is substantially limited to a second range of wavelengths that corresponds to the atmospheric absorption peak.

Abstract: A system and method are provided for actively illuminating and monitoring a subject, such as a driver of a vehicle. The system includes a video imaging camera orientated to generate images of the subject eye(s). The system also includes first and second light sources offset from each other and operable to illuminate the subject. The system further includes a controller for controlling illumination of the first and second light sources such that when the imaging camera detects sufficient glare, the controller controls the first and second light sources to minimize the glare. This is achieved by turning off the illuminating source causing the glare.

Abstract: A system and method are provided for monitoring an eye. The system includes a video imaging camera oriented to generate images of an eye. The camera is aligned along an imaging axis. A first light source is located at an angle less than 2.5 degrees of the imaging axis for illuminating the eye. A second light source is arranged at an angle greater than 4.5 degrees from the imaging axis for illuminating the eye. The system includes a processor for processing the images generated with the video imaging camera during illumination of the eye with the first light source and during illumination of the eye with the second light source.
