  • Patent number: 9723991
    Abstract: An apparatus and method for photodynamic therapy or photodynamic diagnosis using an illuminator comprising a plurality of light sources generally conforming to a contoured surface and irradiating the contoured surface with substantially uniform intensity visible light. The light sources may comprise generally U-shaped fluorescent tubes that are driven by electronic ballasts. The spacing of the U-shaped tubes is varied to increase the output at the edges of the illuminator to make the output more uniform. Also, different portions of the tubes are cooled at different amounts, to improve uniformity. A light sensor monitors output from the U-shaped tubes to provide a signal for adjusting the output from the tubes.

  • Patent number: 9081102
    Abstract: A semiconductor diode scintillation detector probe, in conjunction with a base-line-stabilized, wide-bandwidth first amplifying circuit DC-coupled to a constrained-bandwidth second amplifying circuit DC-coupled, in turn, to a novel analog threshold discriminator circuit, suppresses base-line fluctuation and noise at low input count-rates, while providing a linear rate-meter response for time-random input pulse rates far in excess of what would otherwise—as in the prior art—be 100% saturation.

  • Patent number: 8216289
    Abstract: An apparatus and method for photodynamic therapy or photodynamic diagnosis using an illuminator comprising a plurality of light sources generally conforming to a contoured surface and irradiating the contoured surface with substantially uniform intensity visible light. The light sources may comprise generally U-shaped fluorescent tubes that are driven by electronic ballasts. Adjustment of the ballast voltage controls the output power of the tubes. The tubes are supported by a sheet-metal or plastic housing and are covered by a polycarbonate shield which directs cooling airflow within the unit and prevents glass-patient contact in the vent of tube breakage. An aluminum reflector located behind the tubes increases both the output irradiance and the uniformity of the output distribution. The spacing of the U-shaped tubes is varied to increase the output at the edges of the illuminator to make the output more uniform. Also, different portions of the tubes are cooled at different amounts, to improve uniformity.

  • Publication number: 20120151820
    Abstract: The Boat Buddy Portable Gear Keeper and Cup Holder is an aluminum designed boat and/or fishing gear box with hinged lid and attached cup holder. The item is designed to be portable in nature so that it may be positioned anywhere on a boat at the convenience of the boat owner. The design accommodates any type of boat with a rail or gunwale. The front of the box has an attached cork board so that fishing lures may be easily attached and kept handy for quick access. The box is primarily designed for the fisherman who moves to different areas of the boat and has the need to access the contents without having to go to a central location each time an item is needed. This keeps the fisherman from having to move around the boat and minimizes the chances of him or her from losing balance due to restricted movement.

  • Publication number: 20060279102
    Abstract: Cover systems for vehicles are disclosed. An exemplary vehicle cover comprises a first housing base and a second housing base for mounting on a vehicle, each housing base having at least one channel formed therein. A pulley system is mounted in the first and second housing bases, the pulley system operable to move a cable through the at least one channel formed in each housing base. At least one support bow is mounted on one end to the cable in the at least one channel of the first housing base and mounted on an opposite end to the cable in the at least one channel of the second housing base, the at least one support bow moving between a retracted position and a closed position over the vehicle in response to operation of the pulley system.
