Detecting video phenomena, such as fire in an aircraft cargo bay, includes receiving a plurality of video images from a plurality of sources, compensating the images to provide enhanced images, extracting features from the enhanced images, and combining the features from the plurality of sources to detect the video phenomena. The plurality of sources may include cameras having a sensitivity of between 400 nm and 1000 nm and/or may include cameras having a sensitivity of between 7 and 14 micromet...

The present invention provides a viewing device, said device being positioned within the outer and inner surfaces of an entry door, to ascertain the identity of prospective entrants from within the confines of a dewlling. The device includes on the outer surface of the door a turret wherein at least four ports retain a like series of wide angles lenses. One of said ports and its lens is situated axially along a line from the eyepiece for straight ahead viewing, while the three ports and complime...

A stereoscopic camera having wide angle lenses separated by the normal interpupillary distance photographs a scene on separate 38 mm-square frames of 120-size film strip to provide a left slide and a right slide. The stereoscopic viewer for viewing these slides has separate left eye and right eye assemblies with wide angle lenses having the same focal length as the lenses in the camera and separate supports for the slides. Each of the lenses is individually focusable and provides a borderless, c...

The invention is directed to a viewing arrangement (1) having a viewing optic (3) for viewing an object (5) along a viewing beam path. The viewing arrangement (1) also has an illuminating apparatus (9) for illuminating the object (5) along an illuminating beam path running segment-wise transversely to the viewing beam path. A beam-shaping illuminating element (15) is mounted in the segment of the illuminating beam path running transversely to the viewing beam path. The illuminating element (15) ...

A viewing device for receiving video signals and generating corresponding images for viewing comprising a frame or support, adapted to be worn on the user's head, for example, a frame similar to a spectacle frame. The frame supports a pixelated LCD screen in front of each of the wearer's eyes. Respective optical systems located between the user's eyes and the screens allow the user to view the images generated as if they were at infinity. A light-transmitting microlens screen may be located in f...

A viewing device includes a housing defining an interior chamber through which light can pass. The housing includes first and second spaced apart openings communicating with the interior chamber such that light entering the first opening is viewed by a user looking into the second opening. Indicia representing an eye is positioned adjacent at least one of the openings of the viewing device to help attract consumers to the product and to inform the consumers about the intended use of the product.

A rack constructed from a single blank is folded or bent into a shape to accommodate a plurality of test tubes. The rack may include an elongated light source to backlight a series of test tubes.

Apparatus for receiving a stack of flat objects and for serially presenting such objects to a viewing window is disclosed. The viewing apparatus includes a manually operated reciprocal slide member which withdraws objects from the top of a stack and returns the withdrawn objects to the bottom of the stack whereby the objects are advanced upwardly in the stack for viewing.

A viewing device includes a housing defining an interior chamber through which light can pass. The housing includes first and second spaced apart openings communicating with the interior chamber such that light entering the first opening is viewed by a user looking into the second opening. The second opening is further configured to receive sound created by the user and the housing is configured to transmit the sound entering the second opening toward a sound exit location of the housing at or n...

A viewing device and method are provided for use with an image transparency having an associated tracking memory. The viewing device has a display adapted to present at least two illumination patterns, a reader device for obtaining data stored in a tracking memory of an image transparency positioned proximate to the display surface, and a control processing unit. The control processing unit is adapted to receive the obtained data and to generate more than one illumination pattern with a first of...
