Patent number: 9723991Abstract: 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.Type: GrantFiled: May 20, 2014Date of Patent: August 8, 2017Assignee: DUSA PHARMACEUTICALS, INC.Inventors: Scott Lundahl, Rebecca Kozodoy, Ronald Carroll, Elton Leppelmeier

Patent number: 9081102Abstract: 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.Type: GrantFiled: March 15, 2011Date of Patent: July 14, 2015Inventor: Lewis Ronald Carroll

Patent number: 8216289Abstract: 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.Type: GrantFiled: December 16, 2010Date of Patent: July 10, 2012Assignee: Dusa Pharmaceuticals, Inc.Inventors: Scott Lundahl, Rebecca Kozodoy, Ronald Carroll, Elton Leppelmeier

Publication number: 20120151820Abstract: 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.Type: ApplicationFiled: December 18, 2010Publication date: June 21, 2012Inventor: Ronald Carroll
