  • Publication number: 20020171883
    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 the image 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 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.

  • Patent number: 6411991
    Abstract: A system and method for replicating temporary data created by a server is provided. Temporary data for a local server is replicated periodically to a remote server. Temporary data for the remote server is also periodically replicated to the local server. If a server fails, another server begins processing user requests not responded to by the failed server. The user requests are processed with the benefit of the replicated temporary data. Repetitive user input and processing to create and process the temporary data is not required.

  • Patent number: 6379709
    Abstract: A process for obtaining an angiogenesis inhibitor and an angiogenesis activator from shark cartilage comprising, as the key step, the aqueous extraction of dried shark cartilage. The angiogenesis inhibitor obtained is more potent than shark cartilage not subjected to the extraction step. The angiogenesis inhibitor is particularly useful for the prevention or treatment of cancer. The angiogenesis activator is particularly useful for stimulating wound healing.

  • Patent number: 6026325
    Abstract: An implantable cardiac stimulation device having an improved multi-level electronic package is disclosed. The multi-lever package includes at least two stacked internal substrates for mounting electronic circuits, a protective lid for protecting the substrates, and an external interconnect structure mounted on the lid which is also capable of mounting electronic components. The interconnection between the at least two internal substrates is achieved by vertically-oriented wirebonds, and the interconnection between at least one internal substrate and the external interconnect structure is achieved by vertically-oriented brazed-on pins which pass through holes in the protective lid. This construction minimizes the planar dimensions of the electronic package and optimizes space in the physiologically-curved portions of the housing.

  • Patent number: 5741313
    Abstract: A cardiac stimulation device having a reduced volumetric configuration contains a pair of high-voltage cylindrical discharge capacitors positioned at rounded edges within a device container. The capacitors have electrical contact tabs at one end which are inserted directly through apertures formed within an associated electronic module. The capacitor tabs are connected directly to the electronic module eliminating the need for secondary connectors or point to point wiring, thus reducing the number of connections. Direct connection of the capacitors to the electronic module allows for optimal positioning of the module within the container. Specifically, the generally planar module is oriented perpendicular to planar cover surfaces of the container. Irregularly shaped components attached to the surface of the module advantageously extend away from the surface into remaining voids within the container.

  • Patent number: 5472311
    Abstract: A new and improved wind turbine apparatus includes a housing assembly which includes an upper housing surface which includes a leading edge and a trailing edge. The upper housing surface is contoured to create a venturi action and to exert a reduced pressure at the trailing edge when wind flows across the upper housing surface from the leading edge to the trailing edge. A vane assembly is supported on a horizontal axle in a location such that vanes of the vane assembly are responsive to wind blowing in a direction from the leading edge to the trailing edge of the upper housing surface and such that the vanes are also exposed to reduced pressure near the trailing edge, whereby the vane assembly is caused to rotate on the horizontal axle. A base assembly supports the housing assembly and the vane assembly. The base assembly includes a circular guide assembly, and the housing assembly includes a guide-contacting portion for riding on the circular guide assembly in a circular movement.

  • Patent number: 5386014
    Abstract: The present invention relates to chemically modified hemoglobin produced by a novel and efficient method in which stroma-free hemoglobin is first effectively deoxygenated and reduced and then conjugated with a polyalkylene oxide such as polyethylene glycol (PEG) under conditions which maintain the structural integrity of the heme oxygen binding site. In specific, preferred embodiments of the invention, the deoxygenation and reduction is performed under an inert atmosphere by the amino acid cysteine. In additional specific, preferred embodiments, the structural integrity of the heme oxygen binding site is maintained by a high anionic concentration in the reaction mixture. In further preferred specific emodiments of the invention, the polyalkylene oxide is polyethylene glycol; in still further preferred specific embodiments of the invention, the polyalkylene oxide is linked to hemoglobin via a urethane (carbamate) linkage.

  • Patent number: 3995583
    Abstract: Apparatus is provided for continuous manufacture of insulated conductors and includes an extruder and an elongated chamber having a first curing section immediately following the extruder and a second cooling section following the first section. Both sections are substantially filled with a same liquid medium which remains liquid under both curing and cooling conditions. Means are provided for continuously advancing an electric conductor through the extruder wherein a coat of a curable insulating material is applied thereon and then into and through the chamber filled with the liquid medium. The apparatus further includes means for maintaining the liquid medium in the chamber under sufficient pressure to produce void free insulation, and means for maintaining the liquid medium in the first section of the chamber at a temperature at which the insulating material is cured, and in the second section of the chamber at a cooler temperature to cool the cured insulating material.
