One embodiment of a mirror or reflective surface is set onto a ridged material. The mirror or reflective surface is set at a precise angle by support legs that inserted into holes in the ridged material. The support legs can also be placed in storage notches in ridged material.

A virtual reality cell phone includes: a main body including a display; an ocular plate configured to maintain a variable distance from the rear surface of the main body; and a screen and distance adjustment member interposed between the main body and the ocular plate, and configured to move the ocular plate between a retracted state in which the ocular plate comes into close contact with the main body and an extended state in which the ocular plate maintains a predetermined distance from the main body. The screen and distance adjustment member includes a plurality of screen boxes configured to slide backward and be fixed while being laid over each other.

An inflatable light box includes securing plates and panels in association with upper and lower interior connecting planks when coupled to a cylindrical barrel in which an inflatable airbag is disposed, and encompassed by a decorative cover, form a housing for an inflatable light apparatus.

The image displayable eyeglasses include: a first transmissive optical element 13 that transmits an image of a subject and is capable of changing a refractive power; and a second transmissive optical element 13 that displays or reflects an image using an image signal and transmits the image of the subject. The image displayable eyeglasses are capable of switching between an image display mode, in which the image is displayed or reflected by the second transmissive optical element 12 so as to be incident on eyes of a wearer of the eyeglass body, and an eyeglass mode, in which the image of the subject transmitted through the first transmissive optical element 12 and the second transmissive optical element 13 is incident on the eyes of the wearer. The first transmissive optical element 12 is disposed closer to the wearer than the second transmissive optical element 13.

A kit for creating a flat folding projection device is provided and includes a lens and a sheet defining at least a first, second, third and fourth panels, each panel separated from the other panels by at least one fold. A hole is positioned in the first panel, the hole defining an edge. A cut is positioned in the first panel adjacent to the hole such that the first panel on either side of the cut can be separated to create a space configured to receive and hold the lens therein. Further includes is one of: a light source, a translucent sheet or a light source and a translucent sheet. An envelope contains the foregoing such that a thickness of the envelope is less than inches.

An apparatus for head-mounted displays may include (i) a flexible planar support frame, (ii) a left eye cup coupled to a left side of the flexible planar support frame and a right eye cup coupled to a right side of the flexible planar support frame, (iii) left-eye and right-eye display screen areas mounted to the flexible planar support frame such that the left-eye display screen area projects toward a left eye aperture defined by the left eye cup and the right-eye display screen area projects toward a right eye aperture defined by the right eye cup. The flexible planar support frame may be bendable such that the distance between projections of the left-eye and right-eye display screen areas onto a viewing plane varies as the flexible planar support frame bends, thereby adjusting for varying interpupillary distances. Various other devices, systems, and methods are also disclosed.

A hand-held emergency vision apparatus comprises an enclosed tubular structure having opposite first and second ends; first and second clear members disposed at respective the first and second ends; the structure including a plurality of tubular members retractable to a shorter length and extendable to one of several lengths, the tubular members are rigid and sealed from the outside air; and a filter operably associated with the tubular structure to filter the outside air such that when the tubular structure is extended from the compact form air the outside air is forced through the filter and clean air enters the tubular structure.
