A puzzle using Moebius topology and three-dimensional construction to make solution more challenging by preventing the player from seeing all possible layouts at any one time. The preferred embodiment of the puzzle challenges players to solve a maze when part of the maze will always be concealed by the current viewing surface, as the internal and external surface are both contiguous and identical.

Three-dimensional storage system wherein all storage positions are selectably accessible. An information storage system is provided having conductor paths arranged in three spatial directions. The electrically conductive junctions formed at each intersection of three mutually perpendicular conductor paths provide the respective storage positions. All conductor path systems which terminate in a common column at one exterior surface of the system and all conductor paths terminating in a common row...

A varifocal mirror is typically comprised of a thin aluminized Mylar film that is stretched over a loudspeaker driven sinusoidally at low frequencies. When an object is placed a short distance from the film and the film is oscillated, the position of the image of the object in the mirror will be constantly swept back and forth in the image space with an amplitude typically several times the mirror displacement. In the system herein described a first varifocal mirror is used to sweep a virtual im...

An animated two-dimensional character defined by a fixed outline applied to a flat board and a plurality of movable character features positioned on top of the outline and movable with respect to it. Some of the features are mounted to a first bar that is loosely secured to the board and centered in an original position with respect to the outline while others of the features are mounted to a second member such as an independently movable second bar placed on top of the first bar and also center...

A dimensional display flagger has a normally flat-lying display body and oppositely extending supporting arms with a flexible but form-stable spacing portion connecting the body and arms, the relationship being such that the spacing portion will buckle when the arms are moved longitudinally toward one another, whereby to thrust the display body into a substantially spaced plane relative to the arms. This device is especially useful as an attention-getter on merchandise sales shelves, and the lik...

Apparatus and method control dimensions of corrugated tubing by stretching tubing predetermined amount as it travels between molding unit and downstream pulling assembly running at about same rate tubing is discharged from molding unit. First counter mechanism adjacent discharge end of molding unit counts predetermined number of corrugations in tubing and immediately thereafter generates signal indicating that predetermined number has been counted. Generation of signal from first counter trigger...

The high frequency difference between the complete respective left and right eye representative video signals is shifted to the low frequency video signal spectrum and transmitted at reduced amplitude in the vestigial sideband of the picture carrier, the complete sideband of which conveys one of the complete video signals to a receiver at which the complete video and difference signals are separately recovered, the latter being restored to its original amplitude and position in the frequency spe...

The upholstery element is adapted to provide a resiliently yielding support and comprises individual rod-shaped resilient inserts spaced apart in the direction of one dimension of the upholstery element and extending in said upholstery element in a longitudinal direction which is transverse to the direction in which they are spaced apart, connecting layers of foam disposed between said inserts and constituting the only connection between said inserts and adapted to take up forces which occur bet...

Interactive method and apparatus for producing three-dimensional television wherein means having a computer and stored program device feeds a standard television monitor with two separate signals to produce a stereographic display in different colors that can be viewed through separate colored filters for three-dimensional television viewing by a large number of people.

A three dimensional puzzle formed of several, similarly or differently colored, stacked layers of interlocked puzzle segments with each layer containing one or more voids through which portions of the layers beneath it and the interior surface of a supporting tray are visible to produce a pleasing visual effect.
