APPARATUS AND METHOD FOR MOUNTING AND CALIBRATING A HELMET-MOUNTED DISPLAY
First Claim
1. An apparatus comprising:
- a first mounting bracket affixed to a first portion of a helmet, the first mounting bracket having a first mounting surface; and
a display pod having a second mounting surface, the display pod having a display device that is adapted to display images, the display pod having a disengaged state, in which the second mounting surface is positioned opposite the first mounting surface, the second mounting surface can be moved and rotated relative to the first surface, and an engaged state in which the second mounting surface is positioned against the first mounting surface and the position of the second mounting surface is fixed relative to the first mounting surface.

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.

24. A method of mounting a display pod to a helmet, the display pod including a transparent display device and being part of a helmet-mounted display system, the method comprising:
-
(a) positioning the display pod so that the display device is located in a line of sight of an eye of a person wearing the helmet by moving a second surface located on the display pod relative to the first mounting surface located on the helmet; and (b) retaining the location of the display device in the line of sight by positioning the second mounting surface against the first mounting surface and affixing the position of the second mounting surface relative to the first mounting surface. - View Dependent Claims (25, 26, 27, 28, 29, 30, 31, 32)
