US Classification:

2502015, 250216

Abstract:

An opto-electronic data acquisition and storage system, having a light source for directing light along a predetermined light path, a light sensitive electronic memory, a light absorber, a spatial optical storage device being positioned to receive reflected light and to direct the reflected light to the light sensitive electronic memory and a digital light processor having an array of electronically positioned micro-mirrors each being selectively oriented to a reflecting position to reflect light from the light source along a reflected light path to the spatial optical storage device for data storage and being selectively oriented to reflect light from said source to the light absorber when the reflected light is not intended for storage. This invention also includes an opto-electronic circuit for electronic signal and data processing and storage, having a layered electronic circuit matrix having a plurality of light sensitive layers each having a multiplicity of electronic circuit components being sensitive to light of a predetermined wave-length. The light system generates light beams of differing wave-length; and controls the light beams to program an infinite variety of electronic circuits within the light sensitive layers of the electronic circuit matrix.

Abstract:

A system for converting an image into a hologram formed from diffraction gratings includes obtaining image data for each pixel in an image to be converted, putting it into digital form and using the image data to control portions of a laser beam split into a reference beam and at least one object beam. The diffraction gratings are formed by an interference pattern of a reference beam and at least one object beam intersecting on the surface of a photoresist material on a pixel-by-pixel basis. Modulation of at least one object beam and adjustment of the angle at which that beam interferes with the reference beam on the photoresist material is used to reflect image data for each pixel of the image being converted into a hologram consisting of diffraction gratings. By using this technique and selecting the spacings between pixel pairs on the photosensitive surface, the angle at which a viewer will see a predetermined image or reflecting light from the hologram is determined, as well as the apparent position of the image created by reflecting light from the hologram constituted by the spaced diffraction gratings.

The diffraction gratings are formed by an interference pattern of a reference beam and at least one object beam. intersecting on a profitable surface on a pixel-by-pixel basis. Modulation of at least one object beam and adjustment of the angle at which that beam interferes with the reference beam on the profitable surface is used to reflect image data for each pixel of the image being converted into a hologram. By using this method and selecting the spacings between pixel pairs on the profitable surface, the angle at which a viewer will see a predetermined image or reflecting light from the hologram is determined, as well as the apparent position of image created by reflecting light from the hologram comprising the spaced diffraction gratings.

Frank S. Davis - Houston TX, US

International Classification:

F02B 53/04

US Classification:

123236, 123403

Abstract:

A radial pulsed rotary engine a rotor mounted for rotation between two parallel circular discs and creates pulsed focused fuel/air mixture ignitions sequentially within many wedge shaped chambers of a flat circular rotor. The rotor has a number of wedge shaped chambers that are defined by a number of rotor partitions that extend from positions near the center of the rotor to positions at or near the outer periphery of the rotor and are sequentially in communication with a fuel/air supply, defined by one of the disks, and an outer peripheral portion that is sequentially in communication with exhaust discharge openings that are defined by a housing within which the rotor is positioned. Spark plugs are mounted to the housing and fire sequentially in response to the position of the rotor within the housing.

Abstract:

A method for converting a 2-D image into a hologram is set forth. An optical scanner system which measures the primary color intensity of a selected pixel and forms an indication thereof is disclosed. The location of the pixel is output as XY coordinate data. The location and color data is stored in memory, and the memory is thereafter retrieved. A pixel is located on a blank, and a laser beam split into four equal segments is focused along four separate pathways to the pixel location. Interference fringes formed at the point of convergence on the blank enables transfer of a single pixel, and multiple pixels are transferred so that the entire image is reproduced.
