A heat dissipation structure for a belt starter generator (BSG) which reduces the temperature of one or more ground screws used to connect a printed circuit board (PCB) to a cooling device of the BSG. The PCB is part of an inverter, and the inverter of the BSG is grounded using two ground screws that fix the PCB to the cooling device. A heat dissipation bridge is connected to the two ground screws, the PCB, and the cooling device. The heat dissipation bridge is connected to the grounds screws such that the heat dissipation bridge is located and in contact with an area of the cooling device where the coolant is flowing through a flow cavity. The heat dissipation bridge absorbs the colder temperature from the cooling device therefore lowers the temperatures of the ground screws to a safe level for the components of the PCB.

Light re-reflection in a picture generation unit for a heads up display is reduced by a housing having walls that are 'surfaced' to have inclined surfaces, which reflect light incident upon them toward inclined surfaces on a second and opposing surfaced wall. Re-reflections of light off the surfaced sidewalls attenuates light to a degree that it cannot generate a visible image.

Picture generating unit having internal reflection reduction

Anomalous images generated by a picture generation unit of a heads up display are suppressed by a light-suppressing horn placed inside the picture generated unit. The horn is sized, shaped and arranged to receive scattered light that is reflected from mirrors of a digital micromirror device, which are in their 'off' position but which nevertheless reflect light toward surfaces of the picture generation unit and which are subsequently emitted from the picture generation unit lens.

A pointer for an instrument cluster assembly of a motor vehicle is provided. The pointer includes a pointer arm and a light distributor formed of light conducting material. The pointer arm has a proximal end and a distal end. The light distributor is disposed at the proximal end. The light distributor has a light receiving side and a light reflecting surface. The light distributor is configured to receive rays through the light receiving side. The light reflecting surface is configured to reflect rays into the pointer arm. The light receiving side has an inner portion and an outer portion. The inner portion is disposed closer to the distal end of the pointer arm than the outer portion is with respect to the distal end. Angled surfaces are disposed on the inner portion. The angled surfaces are configured to refract rays toward the light reflecting surface.

High light efficiency pointer illumination

A gauge assembly which has a gauge surface including graphics representing a vehicle operating parameter. A pointer arm is provided which is made out of a light guide or light transmitting material. The pointer arm includes a step portion in an operative portion of the second bottom surface for reducing light received by said second surface adjacent the step portion and providing an overall even light throughout the operative illuminated viewing surface of the pointer arm.
