Abstract: An illuminated instrument cluster utilizes a single light emitting diode to backlight the entire dial surface. The LED is aligned with a light guide then directs light into a cavity of a light housing. The cavity includes a surface that reflects light upwardly onto a back surface of the dial face to provide the desired illumination.

Abstract: A pointer assembly includes the pointer and hub that are both illuminatable. The hub includes a main portion with a concave surface. A reflector is partially received within a slot through the concave surface and is supported on top of the hub. The reflector includes a reflective surface that directs light onto the concave surface. Light from a light source is directed by separate reflective surfaces on the pointer and the reflector to illuminate both the hub and the pointer.

Abstract: An instrument cluster assembly includes an outer gauge that is disposed about an inner gauge. The inner gauge is flood lit and the outer gauge is back lit. A single light guide assembly receives light from a plurality of light source exposed about an outer perimeter of the outer gauge. Light directed through the light guide is emitted through a light emitting edge to illuminate the inner gauge. Light traveling from the light source through the light guide is uniformly transmitted through a curved transition portion to back light the outer gauge assembly.

Abstract: A vehicle display includes two colored light sources that are operatively connected to a circuit board. Each of the two colored light sources emits a colored light that mixes to form a desired color of display light that illuminates a vehicle graphic. The desired color of display light is within a predetermined color tolerance. The vehicle display achieves a small size without incurring added expenses associated with using more than two light sources.

Abstract: A light guide assembly for illuminating an instrument surface includes a continuous curved transition portion for uniformly directing and transmitting light from a light source to a backlight surface of the instrument surface. The curved shape of the transition portion is tailored to transmit a desired amount of light into the backlight portion and a desired amount outwardly against a back surface of the instrument surface.

Abstract: An illuminated pointer includes an outer pointer that surrounds an inner pointer. The outer pointer extends from a base and is generally elliptical. The inner pointer extends from the base into the void of the outer pointer. The illuminated pointer utilizes a single light source for illuminating both the outer and inner pointer. The inner pointer provides easier reading of a dual scale gauge such as with a speedometer having both English and Metric speed scales.

Abstract: A light distributing assembly for a vehicle instrument panel includes a light source that emits light in a first direction. A first surface that is transverse to the first direction receives the light and changes the direction of the light to a second direction. A vehicle instrument panel housing having a second surface receives the light from the first surface and reflects a portion of the reflected light toward a vehicle display surface to illuminate the vehicle display surface.

Abstract: An instrument display system provides vehicle information where a driver and passenger side of a vehicle dash have primarily identical appearances when the display system is not activated. The instrument display system includes a primary light system, a primary optical system, and a semitransparent screen used to produce an image of at least one instrument gauge. The primary optical system directs a light from the primary light system to the semitransparent screen, which is attached to the vehicle dash. The semitransparent screen has a similar appearance to the dash. Thus, when the instrument display system is turned off the semitransparent screen blends with the dash. Other embodiments may use additional light systems and optical systems, such that the scales and indicator for an instrument gauge are produced separately, yet displayed in the same location of the dash.

Abstract: A vehicle instrument cluster 10 includes a dial or display 16 having a graphical image that is illuminated by a light source. The light source is mounted to a printed circuit board (PCB). A light housing is used to support the dial relative to the PCB. The light housing includes an inclined reflective surface that is located directly above the light source. The light housing also includes at least one radially extending channel used to more evenly illuminate a desired portion of the graphical image. The channel includes a flat portion that is mounted directly to the PCB. An intermediate portion extends from the flat portion and is spaced apart from the PCB to define a gap. The instrument cluster control electronics are mounted to the PCB within this gap. A beveled portion extends from the intermediate portion upwardly toward the dial.

Abstract: The brake booster has an envelope (10) with an axis of symmetry (X-X') separated sealingly by at least one movable partition (12) to define at least a first chamber (14) connected permanently to a source of low pressure and at least a second chamber (16). The second chamber (16) being selectively connected to the first chamber (14) or a source of high pressure through a three way valve structure actuated by a control rod (30,130). The three way valve structure has a plunger (28,128) which slides in a bore (26,126) of a piston (20,90) is connected to a control rod (30,130). The position of the plunger (28,128) in bore (26,126) selectively controls the communication between the first chamber (14) and the second chamber (16) or communication between the second chamber (16) and the source of high pressure.
