Patent number: 7277176Abstract: An imaging system for obtaining images of a specimen that includes a novel filtering system for filtering radiation emitted from the specimen. The imaging system includes a camera and a novel filter grid that is controllably movable relative to the camera in a manner to move a selected emission filter of a plurality of emission filters carried by the grid into position between the camera and the specimen. The filter carrying grid of the system resides in a plane having X and Y coordinates and the system includes a novel positioning mechanism for controllably moving the filter carrying grid along the X and Y coordinates of the plane in a manner to position a selected one of the emission filters carried by the grid into position between the camera and the specimen.Type: GrantFiled: May 10, 2005Date of Patent: October 2, 2007Assignee: UVP, Inc.Inventors: Darius Kelly, Sean Gallager, Jeff Pieri, Dave Wick

Patent number: 5757133Abstract: An arc lamp having a sealed lamp tube with electrodes to either side of a septum. The septum extends through the length of the arc chamber. An emissions chamber extends from the end of the arc chamber without the septum. A window at the end of the emissions chamber is displaced from the end of the septum and from the arc chamber itself by a sufficient distance so that magnesium diffusing from the electrodes does not darken the surface. The magnesium electrodes are slugs encased within high temperature cells open at one end.Type: GrantFiled: March 12, 1996Date of Patent: May 26, 1998Assignee: UVP, Inc.Inventors: Ronald A. Meyer, Michael P. Duffey, Robert A. Foss

Patent number: 5736744Abstract: A wavelength shifting filter having two sheets of material adjacent and parallel with a spacer therebetween about the periphery of the sheets. The sheets are held in a frame. A phosphor coating is located on the inner side of one of the sheets. A transilluminator is associated with the filter and provides radiation in the UV wavelength. One sheet of the filter transmits the UV wavelength. The other sheet transmits at least a portion of the wavelength that the phosphor coating generates when subjected to the UV radiation of the transilluminator. The visual effect of white light is enhanced by the use of white glass.Type: GrantFiled: March 27, 1996Date of Patent: April 7, 1998Assignee: UVP, Inc.Inventors: James W. Johannsen, Alexander Waluszko, Ronald A. Meyer

Patent number: 5690531Abstract: A lamp including an elongate tube with a septum extending longitudinally therethrough to near the distal end of the tube. A pair of assembled leads and electrodes are positioned in the tube through the terminal end and the tube sealed. With an end cap on the distal end of the tube, an elongate cavity is formed extending along either side of the septum and joined at the distal end. A bend is made in the tube such that the ends of the electrodes extend into areas within the elongate cavity between the bend and the distal end of the tube.Type: GrantFiled: October 22, 1996Date of Patent: November 25, 1997Assignee: UVP, Inc.Inventors: Robert A. Foss, Patrick M. Lewis, Michael P. Duffey

Patent number: 5670786Abstract: A transilluminator having two sets of tubes selectively providing light in the ultraviolet and visible ranges. The sets of tubes are arranged in two rows on opposite sides of a reflector in a housing having windows with lenses in opposite sides. The two sets of tubes have separate circuits sharing a common ON/OFF switch and a mercury switch mounted to the housing. With the device on, the orientation of the housing determines which of the two sets of tubes is on and which is off. Two sets of mounts to stably retain the housing on a planar surface are arranged on the opposite sides so that the housing may be positioned and used in two orientations. In either orientation, the upwardly facing lamps are energized while the downwardly facing lamps are turned off.Type: GrantFiled: July 18, 1995Date of Patent: September 23, 1997Assignee: UVP, Inc.Inventors: Ronald A. Meyer, Alexander Waluszko

Patent number: 5387801Abstract: A UV transilluminator having three sets of tubes selectively providing ultraviolet light in the short, mid and long ranges. The sets of tubes are arranged in two rows with the upper row including alternating tubes of the first and second set. One of the first and second sets of tubes is transparent to UV radiation. The third set of tubes is arranged in the second row directly behind the transparent tubes of the other set. A filter overlies the sets of tubes with the transparent tubes located between the third set of tubes and the filter.Type: GrantFiled: June 10, 1993Date of Patent: February 7, 1995Assignee: UVP, Inc.Inventors: Ramon R. Gonzalez, Alexander Waluszko

Patent number: 5050055Abstract: A high intensity lamp has a housing formed by first and second housing halves fitted together, a rear cover and a front cover. The first and second housing halves have a handle integrally formed therewith so that the lamp is portable. The housing encases a socket, the high intensity lamp source, a lamp shield and a filter, as well as part of a power cord. The front cover is releasably attached to the first and second housing halves. The filter is releasably attached to the housing halves by means of a retainer, disposed in the housing halves, having inwardly inclined tongs with respect to the housing, which hold therebetween a projection from the filter. The rear cover and each housing half has several elongated ventilation slots. The front cover has feet on which the lamp can rest. The feet are reinforced by ribs which serve, together with tabs, to hold a splash shield in place in the cover.Type: GrantFiled: August 28, 1989Date of Patent: September 17, 1991Assignee: UVP, Inc.Inventors: James R. Lindsay, Ronald A. Meyer, Alexander Garcia, Jr., Alexander Waluszko

Patent number: 4575330Abstract: A system for generating three-dimensional objects by creating a cross-sectional pattern of the object to be formed at a selected surface of a fluid medium capable of altering its physical state in response to appropriate synergistic stimulation by impinging radiation, particle bombardment or chemical reaction, successive adjacent laminae, representing corresponding successive adjacent cross-sections of the object, being automatically formed and integrated together to provide a step-wise laminar buildup of the desired object, whereby a three-dimensional object is formed and drawn from a substantially planar surface of the fluid medium during the forming process.Type: GrantFiled: August 8, 1984Date of Patent: March 11, 1986Assignee: UVP, Inc.Inventor: Charles W. Hull
