Abstract: The present disclosure relates generally to a system and method for monitoring a display output of a graphics processing unit (“GPU”), and more particularly, to monitoring safety critical symbols of a commercial off the shelf (“COTS”) GPU to ensure a high level of accuracy of the display output to be displayed to a user. The generated display output signal of the COTS GPU may be encoded with specific reference points within a generated image, and compared to a predicted image for the monitoring device having corresponding specific reference points. By having specific reference points in the encoded display output signal of the COTS GPU, the monitoring device may significantly reduce processing and throughput but focusing the comparison on only the specific encoded reference points and thereby confirming the accuracy of the COTS GPU.

Abstract: A helmet mounted display (HMD) system comprising (i) a display device adapted to be positioned between an eye of a person wearing the helmet and a vision-related device; and (ii) a step-in visor which is positioned between the eye of the user and the display device. The vision-related device is removably attached to an accessory joint so that it can be interchanged between an outer visor for use during the day and night vision goggles for use during the night.

Abstract: A system for aligning a plurality of high-precision lenses in a lens train. Each of the lenses has at least two alignment tabs disposed around the perimeter of the lens. The lenses are aligned by placing the lenses in a jig having a plurality of high-precision alignment blocks. The lenses are attached to a lower-precision shroud, having slots that receive the alignment tabs. A gap-filling adhesive is used to provide a high-precision fit for the lenses in the shroud.

Abstract: A helmet mounted display (HMD) system comprising a display pod having a light wave optical element. The display pod is designed to be attached to a base plate located above the brow of a helmet using opposing hook and loop-style fastener pads or alternatively, a pair of locking disks. The mounting position of the display pod is adjustable within three degrees of freedom, including lateral positioning along a plane that is co-planar to a mounting surface for the display pod, as well as rotation about an axis that is perpendicular to the mounting surface. The HMD system is adapted to compensate for variations in mounting position using a bore sighting adjustment.
