Abstract: A pad shape for a support assembly is optimized to provide universal fitting characteristics to Head-Mounted Display (HMD) devices. The pad shape enables a display of a single HMD device to be reliably aligned within multiple users' fields-of-view notwithstanding significant variations of shape and size between these users' heads. Optimal positioning of the display within the multiple users' fields-of-view may be achieved by positionally constraining the HMD device against a portion of the head that varies relatively slightly as compared to other portions of the head. The contact pad includes a curved region having a shape defined by a high order polynomial that corresponds to an empirically determined best fit surface. Empirically determining one or both of the best fit surface or the high order polynomial may include aligning a plurality of “forehead” point clouds that map the geometries of a sample set of users' foreheads.

Abstract: A Near-Eye-Display (NED) device having a housing shell that is integrated with molded boss clusters for precision mounting of hardware components. The techniques disclosed herein include forming a housing shell directly over one or more pre-molded boss clusters that have been inserted into cavities of a housing shell mold core. For example, with the pre-molded boss clusters already inserted into the cavities, a selected housing shell material such as a thermosetting epoxy resin impregnated carbon fiber reinforced (CFRP) fabric may be thermal compression molded over the housing shell mold core. Individual ones of the pre-molded boss clusters include one or more “three-dimensional (3D)” bosses for mounting various hardware components of the NED device. The bosses may protrude from an inner surface of the housing shell and may provide interior mounting features without affecting the appearance of the outer surface of the housing shell.

Switchable electronically between first and second optical states, the redirection optic is configured to receive a display image from the microprojector, to convey the display image, in the first optical state, to the first viewer optic, and to convey the display image, in the second optical state, to the second viewer optic.

The electronic controller is further configured to, during a second interval, switch and maintain the redirection optic in the second optical state and cause the microprojector to form the display image based on second image data.

Abstract: A printed circuit board (PCB) incorporates at least one damping layer or section. The at least one damping layer is incorporated in the PCB to absorb vibrations or oscillations that may be conveyed to the PCB. Such vibrations or oscillations may be generated by one or more electrical components coupled to the PCB. The damping layer is disposed to prevent the PCB from audibly vibrating when the electrical components associated with the PCB are caused to vibrate or pulsate under a voltage load.
