    Abstract: In one or more embodiments, wedge light guides are constructed that are monolithic in nature and include integrally-formed optical concentrators. The wedge light guide and its associated optical concentrators are defined by a mold. In at least some embodiments, structure within the mold that defines the optical concentrators can be used as injection ports through which formation material can be injected to form the monolithic wedge light guide.

    Abstract: Embodiments are disclosed that relate to fabrication of a laminated optical wedge. One embodiment provides a method comprising inserting a wedge blank into a vacuum molding tool, applying a vacuum to the vacuum molding tool, and removing a layer from a top surface of the wedge blank to expose a machined surface of the wedge blank. The method further comprises laminating a finish piece to the machined surface via an adhesive, wherein the finish piece comprises a smoother surface than the machined surface, and curing the adhesive to form a finished optical wedge. The method further comprises removing the finished optical wedge from the vacuum molding tool.

    Abstract: A display and input system configured to receive tactile user input and provide dynamic display output is provided. The system includes a display device and a plurality of input locations situated over the display device. Each of the input locations is at least partially see-through to permit viewing of imagery generated by the display device, where each of the input locations includes an optical element spaced from an operative surface of the display device and configured to adjust viewer perception of image light emanating from the display device through input location. The display and input system may also be implemented to include mechanically-depressible keys providing keyboard-type input functionality.

    Abstract: Various embodiments are disclosed relating to fabrication of an optical wedge. For example, one embodiment provides a method for manufacturing an optical wedge comprising inserting a wedge blank into a vacuum molding tool and applying a vacuum to the vacuum molding tool to temporarily hold the wedge blank against a molding surface of the vacuum molding tool. The method further comprises removing a layer from a top surface of the wedge blank to expose a machined surface of the wedge blank, and casting a finish layer on the machined surface to form a finish layer of a finished optical wedge.

    Abstract: Injection molding of a part having a nonuniform thickness is provided. One disclosed embodiment of an injection molding device includes one or more side walls, a first mold surface intersecting the side walls and being stationary with respect to the side walls, and a second mold surface intersecting the side walls so as to define with the side walls and the first mold surface a cavity configured to receive a metered amount of injected molten thermoplastic material. The second mold surface is moveable toward the first mold surface in such a manner that a first end of the second mold surface moves a larger physical travel distance toward the first mold surface than does a second end of the second mold surface during a molding process.
