  • Patent number: 6017355
    Abstract: Intercutaneous implant devices useful in intraluminal and extraluminal procedures for externalization of vessels are provided which have a hollow cylinder with an upper and lower end and an interior and exterior surface, said hollow cylinder having a central aperture which is greater in diameter than the exterior expanse of the access site and a length which provides for adequate annular separation of the externalized vessel at the exterior and interior surface of the implant to ensure adequate blood supply to the vessel; a flange extending from the upper end of the hollow cylinder which provides a platform onto which is attached a termination device; and a plane contacting surface extending from the lower end of the hollow cylinder which provides a means for fixation of the implant to the patient.

  • Patent number: 5989067
    Abstract: A protective device for use with a lamp holder for a high-voltage dual-pin lamp, such as a halogen lamp, includes a wall that surrounds the lower portion of an installed bi-pin lamp so as to prevent contact of the installer's fingers with the high-voltage pins. The protective device may also include a transverse rib that prevents the insertion of a low-voltage bi-pin lamp into a high-voltage lamp holder.

  • Patent number: 5958647
    Abstract: A thermosensitive resist used in the manufacturing of printed circuit boards comprising a mixture of polyacrylic acid, a salt of a long chain fatty acid such as silver behenate, an infra-red absorber and modifiers such as additional polymers. In the unheated form the resist can be easily washed away with water-based mild solutions or pure water. When selectively heated by an IR laser a non-soluble, etch resistant composition is formed protecting the copper clad printed circuit board from the etchants used in the process.

  • Patent number: 5888645
    Abstract: A fiber-reinforced composite material and articles of manufacture formed thereof are formed by the method comprising: forming a compound material comprising a mixture of curable matrix-forming binder, heat resistant reinforcing fibers, and at least one particulate material, wherein the curable matrix-forming binder is 5 to 50% by volume of the compound material; curing the curable binder under simultaneous application of externally applied pressure and ultrasonic energy. Articles according to the invention are useful in a multitude of applications, particularly in applications where the article must retain its shape and properties when subjected to temperatures above the melting point of usual thermoplastic materials, e.g. above 1000.degree. C. The method provides dense, thermally stable, coherent composite materials having a desired high density. Forming and curing times are typically 10 times shorter than conventional methods, e.g. for brake pads in about 3-5 seconds.

  • Patent number: 5478614
    Abstract: A radiation thermally imageable, solid toner addressable article comprises a substrate having on at least one surface thereof a layer comprising a) a solid binder which can be converted to a supercooled liquid upon heating and subsequent cooling to room temperature, b) a dye which absorbs radiation (at the wavelength of the imaging device,, e.e., ultraviolet, visible [especially the red], and infrared wavelengths) and converts infrared radiation to thermal energy, and c) a fluorinated surfactant. A directly thermally addressable article does not require the radiation absorbable dye.

  • Patent number: 5442409
    Abstract: A system for generating motion vectors from image data calculates correlation surface values representing image correlation between temporally adjacent images. The system provides a stream of correlation surface values comprising interleaved subsets of correlation surface values from differing correlation surfaces, each subset being a portion of a correlation surface. The system also provides a correlation surface analyzer for receiving the stream of correlation surface values and determining partial result values for motion vectors, a buffer memory for storing the partial result values, and an apparatus for reading out final result values of motion vectors for a given correlation surface.
