Abstract: A display apparatus has a display to emit image-bearing light to a prism assembly that defines an optical path between an incident surface of the prism assembly and an output surface that is orthogonal to within +/?30 degrees relative to the incident surface, wherein the prism assembly has a curved reflective surface opposite the incident surface. The prism assembly encases a beam splitter at an oblique angle to the defined optical path and to both the incident and the output surface of the prism assembly. A shim, in contact against the display surface and against the incident surface of the prism assembly, defines a sealed air gap for light between the display surface and the incident surface. A frame houses the display, the shim, and the incident surface of the prism assembly, wherein the frame further provides connection features for coupling the apparatus to a head-worn article.

Abstract: A display apparatus for wearing over corrective eyewear has a frame structure that supports left- and right-side protective lenses, wherein each protective lens has a rear surface disposed to face toward the corrective eyewear, and a front surface disposed to face the outside-world object scene. A bridging member is hinged to the frame between the left- and right-side protective lenses, wherein the bridging member extends a nose bridge engagement member toward a viewer nose position, wherein the bridging member further has a coupling configured to removably suspend at least one output element of an electronically energized display system over the front surface of the left- or right-side protective lens.

Abstract: An optic providing reduction in secondary or ghost images includes a beam splitter, a reflective surface, and at least one baffle therebetween. A transmissive surface may be located between the beam splitter and the reflective surface. The baffle is positioned to intercept internally reflected ghost rays while being substantially parallel to outside light rays along a line of sight of the viewer, permitting use in see-through optics. The baffles may be formed of light absorbing material, diffusing structures, and combinations of both. Baffles intercept and absorb ghost rays to the exclusion of projected image rays that provide a desired projected image which are internally reflected through the optic. An assembly including such optic integrated with a wearable vision system, such as a head-mounted display, is also disclosed for near-eye application.

Abstract: A head-mounted display apparatus for a viewer has an optical imager having a display generator that is energizable to emit image-bearing light in a first direction and a prism that is configured to redirect the generated light in a second direction that is toward the viewer's eye and orthogonal to within +/?30 degrees relative to the first direction. A housing is configured to form a sealed chamber that encloses at least the display generator of the optical imager and to expose at least a portion of the prism extended from the sealed chamber. A releasable coupling formed onto a cover element of the sealed chamber is configured to cooperate with a mounting fixture formed on headgear worn by the viewer for mounting the housing and suspending the exposed portion of the prism into a field of view of the viewer's eye.

Abstract: An apparatus has a monocular optic for viewing from either a right eye or a left eye of a viewer. A bilateral connecting arm extends between the monocular optic and a coupling on a head-worn article worn by the viewer. The bilateral connecting arm is configured for repeatably decoupling from, and recoupling to, the head-worn article for switching between a first orientation that disposes the monocular optic in a left eye viewing position and a second orientation that disposes the monocular optic in a right eye viewing position.

Abstract: Methods and apparatuses are provided for assembling a structure on a support having a pattern of binding sites. In accordance with the method, a first fluid is provided on the surface of the support with the first fluid being of a type that that increases viscosity when heated, the first fluid having first micro-components suspended therein each adapted to engage the binding sites. The first fluid proximate to selected binding sites is heated to increase the viscosity of the responsive fluid proximate to the selected binding sites so that the first micro-components suspended in the first fluid are inhibited from engaging the selected binding sites.
