Publication number: 20240108332Abstract: A method of operating an articulatable surgical instrument. The method includes providing a rotary drive motion to a rotary drive member of a surgical end effector and converting the rotary drive motion to an upper axial motion and a lower axial motion at locations that are distal to the articulation joint. The method further includes applying the upper axial motion to an upper portion of a firing member and applying the lower axial motion to a lower portion of the firing member such that the upper axial motion and lower axial motion drives the firing member distally through the surgical end effector from a starting position to an ending position.Type: ApplicationFiled: December 12, 2023Publication date: April 4, 2024Inventors: Gregory J.

Publication number: 20220382017Abstract: Systems and methods according to one or more embodiments are provided for annealing a chalcogenide lens at an elevated temperature to accelerate release of internal stress within the chalcogenide lens caused during a molding process that formed the chalcogenide lens. In particular, the annealing process includes gradually heating the chalcogenide lens to a dwell temperature, maintaining the chalcogenide lens at the dwell temperature for a predetermined period of time, and gradually cooling the chalcogenide lens from the dwell temperature. The annealing process stabilizes the shape, the effective focal length, and/or the modulation transfer function of the chalcogenide lens. Associated optical assemblies and infrared imaging devices are also described.Type: ApplicationFiled: August 12, 2022Publication date: December 1, 2022Inventors: Alan D. Kathman, William J.

Patent number: 7849821Abstract: A fuel-fired water heater is provided with a premixing type main burner and an associated pilot burner for igniting it. A specially designed protective system is operative to detect a flame flashback burning condition in the main burner and responsively shut down the water heater. In one embodiment thereof, the protective system uses main burner body heat to melt a portion of a fuel supply line connected to the pilot burner during a flame flashback condition in the main burner. Such melting responsively causes an associated fuel supply valve to close and terminate water heater operation. In a second protective system embodiment a normally closed pressure switch is opened, thereby shutting down the water heater, when the switch detects a pressure indicative of a flame flashback condition in the main burner.Type: GrantFiled: April 12, 2007Date of Patent: December 14, 2010Assignee: Rheem Manufacturing CompanyInventors: Jacob A.

Patent number: 5437756Abstract: A simulator dome for a motion base simulator comprises one or more fiber reinforced outer layers, inner layers of a similar material and an intermediate core. The intermediate core is preferably a structural foam of variable density to allow selectively lowering the dome center of gravity to enhance the simulation capabilities of the motion system to simulate various flight maneuvers. By producing the dome from fiber reinforced polymer and using a core of variable density, a dome of unitary construction with no through fasteners is produced, having high strength for withstanding high G maneuvers without cracking or distortion, enhancing simulator effectiveness and increasing the accuracy of the simulated flight conditions.Type: GrantFiled: June 9, 1994Date of Patent: August 1, 1995Assignee: United Technologies Corp.Inventors: Joseph M.

Patent number: 5126923Abstract: Intense illumination is cast omnidirectionally by a single light source that directs a ligth beam onto a pair of mirrors rotating hundreds of revolutions per second. The mirrors are mounted in an "X" configuration and are thus vibration-free. The light beam is split in half and directed in opposite directions by the mirrors to enable the mirrors to rotate at half the speed of single mirror devices. The light source may be offset from the axis of rotation of the mirrors to shroud preselected areas from illumination.Type: GrantFiled: July 27, 1990Date of Patent: June 30, 1992Assignee: Illumitech, Inc.Inventor: William J.
