Publication number: 20030090679Abstract: An interferometer is used to provide control to the intensity profile and position of a spot of light. In this invention, each light ray from a spectral source is regenerated into a plurality of light rays by an interferometer. These rays are focused by a lens into a constructive interference fringe on an optical disk. A voltage across the interferometer can change the index of reflection of the interferometer thus defines the position of the constructive interference fringe on the disk.Type: ApplicationFiled: December 18, 2002Publication date: May 15, 2003Applicant: RICHARD L. SCULLYInventor: Roland H. Chase

Patent number: 5053320Abstract: The invention relates to a photosensitive composition for direct dry negative color printing composition. The photosensitive composition comprises a binder containing a plurality of grains of a semiconductor material, each grain having adsorbed on its surface one of three different complexes of spiropyran with a metal salt, each complex being sensitive to a different wavelength of light, a cross-linkable polymer and free radical initiator. The composition and process enables photofinishing or printing from a negative.Type: GrantFiled: April 16, 1990Date of Patent: October 1, 1991Assignee: Richard L. ScullyInventor: Jean J. A. Robillard

Patent number: 4905202Abstract: A detection panel for acoustic holography with real time image reconstruction includes, a flat cell containing a mixture of nematic and cholesteric liquid crystals whose composition provides a refractive index which varies as a function of acoustic pressure. The cell has at least one acoustic window and at least one optical window.Type: GrantFiled: December 28, 1987Date of Patent: February 27, 1990Assignee: Richard L. ScullyInventor: Jean J. A. Robillard

Patent number: 4751387Abstract: An infrared imaging system includes a film of dichroic liquid crystal coated on a membrane, first means for forming an infrared image on the membrane, second means for illuminating the membrane with visible light, and third means for deteching variations in elliptical polarization of the light after reflection from or transmission through the membrane to provide a visible image.Type: GrantFiled: January 2, 1986Date of Patent: June 14, 1988Assignee: Richard L. ScullyInventor: Jean J. A. Robillard

Patent number: 4725527Abstract: The invention relates to a photosensitive composition for direct positive color photography. The photosensitive composition comprises a binder containing a plurality of grains of a semiconductor material, each grain having adsorbed on its surface one of three different complexes of spiropyran with a metal salt, each complex being sensitive to a different wavelength of light, a cross-linkable polymer and a free radical initiator. The photographic composition provides a non-silver photographic process based on the photo-decomposition of the metal-spiropyran complex absorbed on the grains of semiconductor material.Type: GrantFiled: December 26, 1985Date of Patent: February 16, 1988Assignee: Richard L. ScullyInventor: Jean J. A. Robillard

Patent number: 4455646Abstract: A pulse code modulated digital automatic exchange for a telephone network or other communication network has a multiplicity of N input/output ports connected to an input/output system comprising a plurality of multiplexers that each scan a small group of ports in a predetermined cycle; output signals from the multiplexers are converted into M-bit parallel digital data signals and recorded in an input data store at a location identified with the port of origin. The input data store is scanned, by a fully bused synchronous transfer system, in accordance with a predetermined transfer time cycle having at least N fixed transfer time slots, one for each communication port; during the transfer time slot for any port, data recorded in the input store from that port is transferred, via an M-digit parallel data bus, to a location in an output data store associated with another port for which that data is destined.Type: GrantFiled: August 26, 1982Date of Patent: June 19, 1984Assignee: Richard L. ScullyInventor: William T. Bloodworth
