  • Publication number: 20080062706
    Abstract: Disclosed are various embodiments of system, devices, components and methods for controllably configuring the brightness and color of light emitted by an automotive LED illumination system. The brightness and color of light emitted by LEDs, or clusters or groups of LEDs, may be varied smoothly or in step-wise fashion to produce virtually any desired pattern of collimated light. Such a pattern may be varied in respect of time or space, or both time and space. Light and other types of sensors may be employed to provide feedback control as a further means of controllably configuring the brightness and color of light emitted by such a system in response to changes in external and other conditions.

  • Publication number: 20080055065
    Abstract: Disclosed are various embodiments of system, devices, components and methods for controllably configuring the brightness of light emitted by an automotive LED illumination system. The brightness levels of LEDs, or clusters or groups of LEDs, may be varied smoothly or in step-wise fashion to produce virtually any desired pattern of collimated light. The pattern may be varied in respect of time, space or both time and space. Light and other types of sensors may be employed to provide feedback control as a further means of controllably configuring the brightness of light emitted by such a system in response to changes in external and other conditions.

  • Patent number: 7220956
    Abstract: Power savings occur when the optical path of an optical navigation device is configured to provide that maximum energy from the light source is reflected by the navigation surface to the photosensors of the optical navigation chip. Additional power savings may be achieved when the maximized optical path is combined with the features of a controlled light source that uses specular reflection.

  • Patent number: 7176442
    Abstract: An optical navigation system, e.g. optical mouse, determines optical navigation quality by examining some or all of the photosensors of a frame or monitoring intermediate or final results of the motion estimation system. The optical navigation quality is then used to determine the navigation output produced by the optical navigation system.
