A three-dimensional television system wherein a plurality of television cameras are disposed, for example, equidistantly from each other on a horizontal plane including a plurality of foreground subjects; each foreground subject is photographed at a plurality of different planes by using those cameras so as to obtain an image corresponding to each plane; the points of the image thus obtained which correspond to specific points of the foreground subject are mutually connected to form an angular d...

Three-dimensional images are produced within a transparent cathode-ray tube by directing a plurality of electron beams into a cloud of phosphorescent particles and causing the beams to intersect at a point within the cloud. Each individual beam's current is maintained at less than the threshold of luminescence of the particles but the combined currents may be caused to exceed that threshold by a controlled amount thereby producing light spots of variable brightness at the beam intersection point...

The apparatus disclosed herein comprises a base having first and second platforms rotatably mounted thereto. First and second rods are mounted in parallel upon the base. First and second wheels have circumferential edges shaped to mate with the rods and are received thereon, a shaft spanning between the wheels and being received within central apertures defined by the wheels. Cables are secured to the rods and extend about the circumferential edges of the respective wheels to permit the wheels t...

A three-dimensional aquarium cover is molded or formed from translucent plastic and includes a peripheral base member having upstanding corner support members and a mating top member, the top member having relatively wide, vertically depending perepheral edges to conceal a lighting fixture and a decorative hollow structure formed in conjunction with the top member to conceal an aquarium pump.

A precision table for a machine tool or the like, which table mounts a workpiece and is adapted to be selectively moved or slid in two directions by a low viscosity bearing such as an externally pressurized air bearing. The bearing includes at least one guide of a substantially J-shaped cross-sectional configuration with a jet arrangement being provided within the guide for jetting a pressurized gas through at least one orifice toward at least one internal surface of the guide. The jet arrangeme...

The three-dimensional display system disclosed herein employs the varying focal properties of a vibrating mirror to cause sequentially generated image components to appear juxtaposed in space. The mirror is constructed as a circular reflective plate having substantial stiffness and resilience. The plate is weighted about its rim and is supported by a flexible support ring engaging the plate along a concentric circular locus spaced inside of the rim so as to provide a useful curvature over substa...

A two dimensional velocity sensor mountable on an aircraft employs a CW radar which illuminates the ground with radar energy. Two transmitters which are alternately activated cause the speckle pattern to move as a whole in the opposite direction at the same speed. Two receivers mounted parallel to the heading axis of the aircraft sense the same power of the backscattered pattern except for a delay. By means of a time-shared processor and computer, this sensed delay provides heading velocity as w...

A three dimensional time piece for determining the correct time anywhere in the world. The time piece having a world globe with a 24 hour time band therearound, and lighting inside the globe to indicate both night time and day time on the surface of the globe. The time piece further indicates the month of the year with changes in light intensity on the surface of the globe to represent the inclination of the sun and the corresponding season of the year.

A game including a base, nine elongated pegs disposed substantially perpendicularly to the base and arranged on the base in spaced relation in three discrete groupings. There is further provided a plurality of pieces each having a hole therethrough which is adapted to accommodate any one of the pegs. The game is readily adaptable to various types of scoring and hence, the present invention provides a game which may be played at various degrees of difficulty. In one embodiment, the pieces are pro...

There is described a magnetic bubble domain device particularly adapted for bubble domain detection. A bubble is supplied via a standard input propagation path, expanded to an elongated bubble comfiguration and replicated into a plurality of bubbles. The plurality of bubbles propagate along a respective plurality of propagation paths and reach a detector portion, preferrably at different times. The detector portion is arranged to receive bubbles along the respective plurality of paths and to pro...
