A phonetic alphabet for communicating with dolphins, porpoises and whales inlcludes three basic geometric shapes, various combinations of which are used to represent speech sounds. The alphabet consists of eighteen symbols which may be understood by animals trained to identify these symbols with words by using their innate echolocation sensory capabilities, and may also be understood visually by human trainers.

A processor capable of performing a two-dimensional transform on high speed serial sampled analog raster scanned data and outputing the results in a parallel fashion so as to provide for a data rate reduction. The processor utilizes a charge coupled device (CCD), a matrix multiplier to perform a one-dimensional transform on data samples from a serial to parallel converter. The data is switched into a set of matrix multipliers which perform another transformation whose results are summed in an ac...

A multiple beam or "multiphoton" absorption effect is used for creating three-dimensioal sensible objects including optical elements and three-dimensional computer-type data storage and retrieval systems. The objects and systems are made according to the invention by at least two beams of optical electromagnetic radiation having a spectral characteristic matched to the excited state properties of active media molecules, wherein the beams are simultaneously or sequentially directed to a common ta...

A three-dimensional photographic system includes a source of pulsed-optical radiation characterized by an output optical pulse of risetime length less than the depth resolution desired of an object to be photographed. The pulse is directed on the object; the reflected radiation from the object is collected by an array of optical lenslets (lenticular plate), which forms a corresponding array of images of the object. This array of images is streaked, for example, by a streaking image converter tub...

A layout tool for defining points on rolled metal H beams comprises a U shape frame having a hand hold in the bight of the U. One leg of the frame is longer than the other and terminates at its end in a stabilizing and guide member extending perpendicular thereto. The guide member has a flat wear surface adapted to be positioned against the working line of the beam on the external surface of the beam to which all measurements are taken. The other leg of the frame slidingly supports in a channel ...

A projection system for providing a magnified image from a holographic transparency in which the transparency is illuminated from one side by a laser, and two lens are serially arranged on the other side of the transparency, the second of these lens having a focal length greater than the first one. An Arnulf afocal plate closely follows serially the second of the lens. A viewer in front of the afocal plates perceives a three-dimensional real image positioned between the viewer and the afocal pla...

An isolation mount for damping radial vibration as well as axial vibrations without attendant shear forces to the elastomeric medium. A toroidal casing has a plate extending through its radially outer wall and terminating with flanges on its radially inner edge near a cylindrical core of the casing. Elastomeric O-rings are disposed on either side of the plate so as to be captured between the respective flange and oppositely disposed casing wall. Relative movement between the plate and the casing...

Apparatus for constructing a puzzle-like figure on a plane wherein certain parts have boreholes into which rods may be inserted, and onto which additional parts may be movably fitted, so as to construct a three-dimensional figure having interlocking parts and movable parts.

A three dimensional alignment game comprising an upstanding gameboard structure and pieces for selective placement therein. The upstanding structure is comprised of five horizontally disposed levels or tables in vertical alignment with each other. Each table is formed of aluminum wire to provide a circular array of eight openings. Each opening of a given table is vertically aligned with corresponding openings of the tables above and/or below the given table. The pieces are in the form of pegs si...

This invention relates to a reflex camera device having a single lens for the photography of right and left images from an object space transmitted as first and second light ray bundles from two positions separated by an interocular distance onto a single frame of a single film strip; a first set of mutually extinguishing filters such as polarizers, one filter of the set along each of the first and second light ray bundles; a single frame aperture; a second set of mutually extinguishing filters ...
