Publication number: 20170043069Abstract: Negative pressure wound therapy systems are described that can prevent the retainment of wound fill material in a wound cavity during dressing changes. The negative pressure wound therapy system includes a removal device that can be used to lift the wound fill material out of a wound cavity and prevent fracture of the wound fill material and retainment of fragments of the material in the wound. The removal device can include fibers (e.g., a fibrous net) that can be retained between the wall of the wound cavity and the wound fill material, with the wall of the wound and the wound fill material retaining direct contact with one another to encourage healing of the wound according to the therapy treatment process.Type: ApplicationFiled: July 27, 2016Publication date: February 16, 2017Inventors: David L. Cull, John David Cull

Publication number: 20060229548Abstract: An arteriovenous graft system is described. The arteriovenous graft system includes an arteriovenous graft that is well suited for use during hemodialysis. In order to minimize or prevent arterial steal, at least one valve device is positioned at the arterial end of the arteriovenous graft. In one embodiment, for instance, the arteriovenous graft system includes a first valve device positioned at the arterial end and a second valve device positioned at the venous end. In one embodiment, the valve devices may include an inflatable balloon that, when inflated, constricts and closes off the arteriovenous graft. By minimizing or preventing arterial steal, other complications associated with arteriovenous grafts are also avoided. For instance, the present invention is also well suited to preventing arteriovenous graft thrombosis, eliminating dialysis needle hole bleeding, and eliminating or minimizing arteriovenous graft pseudoaneurism formation.Type: ApplicationFiled: February 27, 2006Publication date: October 12, 2006Inventor: David Cull

Patent number: 6747413Abstract: An apparatus and method is disclosed for regulating the cold spot temperature of a light emitting enclosure. A cold spot regulation system defines and controls the temperature of the cold spot. The cold spot regulation system includes an interface housing secured to the light emitting enclosure and two ducts extending from the interface housing. The cold spot regulation system uses a coolant fluid to lower the operating temperature of the light emitting enclosure. The coolant fluid is diverted into one of the ducts. The coolant fluid is passed by the cold spot of the light emitting enclosure and released out the other duct.Type: GrantFiled: November 13, 2001Date of Patent: June 8, 2004Assignee: Honeywell International Inc.Inventors: Brian David Cull, Dennis Michael Davey, Alan Stuart Feldman

Patent number: 6666567Abstract: A light source incorporates light emitting diodes (LEDs). The LEDs may be raised off the floor of the optical cavity to permit light to be emitted from the base of the LED. Additionally, a reflective protrusion may be placed beneath the raised LED to aid in redirecting light forward. The LEDs may be skewed in relation to adjacent LEDs to reduce interference. Non-white LEDs may be incorporated into the light source to permit for selective color tuning. Fluorescent lamps may also be implemented in combination with the LEDs to form a hybrid light source.Type: GrantFiled: December 28, 1999Date of Patent: December 23, 2003Assignee: Honeywell International Inc.Inventors: Alan Stuart Feldman, Brian David Cull, Dennis Michael Davey

Patent number: 6339931Abstract: The present invention is directed to a method for charging a self-chilling beverage can, in a self-chilling beverage can of the type involving a container-within-container construction wherein, for example, a granular carbon material is contained within the inner container, and charged with a gas that is absorbed into the carbon material under pressure, the beverage being placed into the space between the inner and outer containers, and further whereupon release of the charging gas, the temperature of the carbon material drops rapidly, enabling a transfer of heat from the contained beverage through the wall of the inner container into the carbon material. The present invention is directed to a method for providing accelerated charging of the charging gas into the inner container, while absorbing and/or transporting away heat generated by the compression of the charging gas. The invention is also directed to an apparatus for facilitating charging of such a self-chilling container.Type: GrantFiled: May 30, 2000Date of Patent: January 22, 2002Assignee: Penguin Plastics Inc.Inventor: David Cull

Patent number: RE41685Abstract: A light source incorporates phosphor-based white light emitting diodes (LEDs). The LEDs may be raised off the floor of the optical cavity to permit light to be emitted from the base of the LED. Additionally, a reflective protrusion may be placed beneath the raised LED to aid in redirecting light forward. The LEDs may be skewed in relation to adjacent LEDs to reduce interference. Non-white LEDs may be incorporated into the light source to permit for selective color tuning. Fluorescent lamps may also be implemented in combination with the LEDs to form a hybrid light source. The light source may be used as a backlight for a liquid crystal display assembly.Type: GrantFiled: April 19, 2007Date of Patent: September 14, 2010Assignee: Honeywell International, Inc.Inventors: Alan Stuart Feldman, Brian David Cull, Dennis Michael Davey
