Disclosed is a viewing system (30) for displaying and viewing stereoscopic images to a viewer's full field of view. The viewing system includes an image display assembly (32) including display surfaces (34) for displaying images primarily to the viewer's area of visual attention and display surfaces (36) for displaying images primarily to the viewer's area of peripheral vision. The display surfaces are mounted in relatively close proximity to the viewer's eyes. The viewing system further include...

A dirt shield for viewing ports of contaminated environments which includes the formation of a cone of flowing gas disposed in front of the window of the port combined with a flow of ionized gas under pressure in front of the window between the window and the cone of gas.

An arrangement for enabling a person to view/observe alphanumeric/pictorial information provided upon a surface of an information storage cassette while being located within an associated case, container, enclosure, housing or the like that is adapted for placement in one-above-the-other relationship and/or in side-by-side relationship in such manner that the information to be viewed/observed is out of direct line of vision of the viewer thereof. The library case, container, enclosure, housing o...

A video viewing system for a vehicle including a vehicle having a battery which, through an inverter, powers a video and audio generating source. The source transmits video signals to a projector which is also powered by the vehicle battery. The projector is affixed to the vehicle, and operative to project video images onto a screen. The screen is removably attached to the hood or a bumper of the vehicle and disposed in cooperation with the projector. The source transmits audio signals to the ve...

An electrical disconnect switch having a viewing window for viewing the internal switching mechanism is disclosed. The viewing window utilizes gaskets, rivets, a substantially transparent viewing window plate, and a viewing window retainer to provide a dust-tight, water-tight and drip-tight viewing window.

A compact hand-held viewing apparatus that automatically determines the three-dimensional direction in which it is pointing and automatically presents information to the user related to features which are visible in the field of view of the apparatus in that three-dimensional direction. Any given embodiment of the invention is intended to be used for viewing a predetermined subject matter, such as astronomical features of the night sky or geographical features of the distant terrain. Included wi...

A unit for viewing and supplying light or radiant energy to the interior of a vessel that has a front fused glass window. The light and camera-viewing means see the interior of a vessel through this fused glass window which provides a substantially corrosion-proof seal across the entire distal portion of the unit. The light and camera-viewing means are pointed into the interior of the vessel in substantially the same direction.

A novel aquatic viewing apparatus is provided for placement on the face of a user which comprises a transparent member positioned in an annular structure of closed cell plastic foam having an inside cylindrical wall and an outside cylindrical wall connected by transverse end walls at either end thereof and the apparatus is capable of supporting the head of a user while in water.

This invention involves a device for lengthy, long-range viewing of objects (e.g. wildlife, sporting events, military activities) while permitting the viewer to view same in relative comfort because the viewing device is mounted on a headgear device. Thus, the viewing means is held still while fatigue is minimized greatly. Also, the device permits use of the hands and arms for other purposes so that frequent movement thereof is avoided. The device includes a hard hat helmet with a viewing monocu...

The present invention relates to an improved collimator assembly that includes two separate optical paths. Each optical path passes through a corrector lens arrangement substantially centered and aligned with one of two eyepiece lens assemblies. Each corrector lens arrangement is constructed so as to selectively refract light passing through it, in such a manner so as to counteract and reduce the axial chromatic aberrations that occur in the eyepiece lens assemblies.
