Publication number: 20240081544Abstract: A buoyant pool lounge chair frame and buoyant pool lounge chair using the same are disclosed. In one embodiment of the buoyant pool lounge chair for supporting a person while the buoyant pool chair is floating in water, frame members collectively form an open chair frame including a back frame and leg frame pivotally coupled thereto. Buoyant cushions are attached to the frame members to form a chair seat, a backrest, and a leg rest. A pair of rear pivotal coupling and clutch assemblies are coupled to the seat frame and to the back frame to adjust and fix the angle of recline of the back frame relative to the seat frame. Similarly, a pair of front pivotal coupling and clutch assemblies coupled to the leg frame and to the back frame to adjust and fix the angle of extension of the leg frame relative to the seat frame.Type: ApplicationFiled: November 21, 2023Publication date: March 14, 2024Inventors: Matthew J. Iles, Christopher B. Holland, Michael V. Nelson

Patent number: 9347894Abstract: An imaging system may include a main enclosure having at least one access door that defines a substantially light-tight imaging compartment when the access door is in a closed position. An object platform provided within the main enclosure holds an object to be imaged. A camera system positioned on a first side of the object platform is operable to capture a visible light image of the object. A radiation detector positioned on the first side of the object platform is moveable from a first position to a second position across a field of view of the camera system. The radiation detector is operable to capture a radiographic image of the object by moving the radiation detector from the first position to the second position while detecting radiation from the object.Type: GrantFiled: August 31, 2011Date of Patent: May 24, 2016Assignee: Spectral Instruments Imaging, LLCInventors: Gary R. Sims, Michael B. Nelson, Michael D. Cable

Patent number: 8901516Abstract: An excitation light source assembly includes a housing defining a central opening therein and a plurality of lamp receptacles surrounding the central opening. The housing is mountable to a support structure having a camera mounted thereto so that a field of view of the camera is substantially unobstructed by the housing. A light source is positioned within each of the plurality of lamp receptacles. A diffuser is positioned adjacent the light source in each of the plurality of lamp receptacles so that each of the diffusers diffuses light produced by each of the light sources. A control system operatively connected to each of the light sources operates selected ones of the light sources to provide a desired excitation illumination to an object within the field of view of the camera.Type: GrantFiled: August 31, 2011Date of Patent: December 2, 2014Assignee: Spectral Instruments Imaging, LLCInventors: Michael B. Nelson, Michael D. Cable

Publication number: 20120229663Abstract: An imaging system includes a main enclosure having at least one access door, the main enclosure defining a substantially light-tight imaging compartment when the access door is in a closed position. An object platform defining an image region therein is provided within the imaging compartment of the main enclosure. A primary camera positioned on a first side of the object platform is operable to capture a primary image of the image region on the object platform. An auxiliary camera positioned on the first side of the object platform is operable to produce an auxiliary image of the image region on the object platform.Type: ApplicationFiled: March 6, 2012Publication date: September 13, 2012Applicant: SPECTRAL INSTRUMENTS IMAGING , LLCInventors: Michael B.

Publication number: 20120049707Abstract: A light-tight door assembly may include a door with a leading side and a non-leading side. The door may be mounted to an enclosure so that the door can be translated with respect to an opening in the enclosure between an opened position and a closed position. A first flange member may be mounted to the non-leading side of the door and a second flange member may be mounted to the enclosure so that the second flange member cooperates with, but does not contact, the first flange member when the door is in the closed position. The non-contact cooperation of the first and second flange members forms a substantially light-tight seal when the door is in the closed position.Type: ApplicationFiled: August 31, 2011Publication date: March 1, 2012Applicant: SPECTRAL INSTRUMENTS IMAGING, LLCInventors: Michael B. Nelson, Joshua Ludeke

Patent number: 7503323Abstract: The present invention provides improved anesthesia delivery systems that consistently and reliably deliver anesthesia gas to multiple gas outlets. The systems are particularly useful for anesthetizing multiple mammals and living specimens to be imaged by a low-light level imaging system. The anesthesia delivery systems are suitable for use with conventional oxygen sources, and convert the high pressures associated with a conventional oxygen source to lower pressures suitable for use with small mammals and suitable for combination with an anesthesia gas at low flow rates. The systems include an anesthesia gas source that combines anesthesia gas with the oxygen. The combination of anesthesia gas and oxygen is supplied to one or more multiple outlets.Type: GrantFiled: February 20, 2002Date of Patent: March 17, 2009Assignee: Xenogen CorporationInventors: Richard G. Dalgetty, Brian R. Bates, Michael B. Nelson

Patent number: 6919919Abstract: The invention describes systems and methods for calibrating a low-level light imaging system. Techniques described herein employ a light calibration device that is placed within a low level light imaging box to calibrate the system and its constituent components such as the camera and processing system. The calibration device comprises an array of low-power light supplies each having a known emission. By taking an image of each low-power light supply, and comparing the processed result with the known emission, the accuracy of the imaging system and its absolute imaging characteristics may be assessed and verified.Type: GrantFiled: February 6, 2002Date of Patent: July 19, 2005Assignee: Xenogen CorporationInventors: Michael B.
