Patent number: 11988043Abstract: Ladders, ladder components and related methods are provided including embodiments of a hinge that may be used in a combination ladder. In one embodiment, a hinge mechanism includes a first hinge assembly and a second hinge assembly. The first and second hinge assemblies are coupled together for relative rotation about a defined axis. An adjustment mechanism enables the two hinge assemblies to be selectively locked or unlocked to prohibit or permit relative rotation, respectively. In one embodiment, the adjustment mechanism includes a lock plate displaceable along a first axis and a retainer displaceable along a second axis. The retainer is configured to hold the lock plate in a disengaged state until a release structure displaces the retainer away from the lock plate. The release structure may be configured to be actuated and displace the retainer upon relative rotation of the hinge assemblies to (or through) a predetermined angular configuration.Type: GrantFiled: October 13, 2020Date of Patent: May 21, 2024Assignee: LITTLE GIANT LADDER SYSTEMS, LLCInventors: Sean R. Peterson, Benjamin L. Cook, Gary M. Jonas

Patent number: 8941968Abstract: An electrostatic clamp is provided, having a clamping plate, wherein a clamping surface of the clamping plate is configured to contact the workpiece. A voltage applied to one or more electrodes selectively electrostatically attracts the workpiece to the clamping surface. One or more auxiliary clamping members are further provided wherein the one or more auxiliary clamping members are configured to selectively secure at least a portion of the workpiece to the clamping surface. A temperature monitoring device configured to determine a temperature of the workpiece is provided, and a controller is configured to selectively clamp the workpiece to the clamping surface via a control of the voltage to the one or more electrodes and the one or more auxiliary clamping members, based, at least in part, on the temperature of the workpiece.Type: GrantFiled: June 3, 2011Date of Patent: January 27, 2015Assignee: Axcelis Technologies, Inc.Inventors: Perry J. I. Justesen, Allan D. Weed, William Davis Lee, Ashwin M. Purohit, Robert D. Rathmell, Gary M. Cook

Patent number: 8797706Abstract: A clamping device and method is provided for securing first and second workpieces having different sizes to a clamping device and providing thermal conditioning thereto. An electrostatic clamping plate having a diameter associated with the first workpiece surrounds a central portion of the clamp. A non-electrostatic central portion provides a heater within the annulus, wherein the central portion has a diameter associated with the second workpiece. A workpiece carrier is provided, wherein the workpiece carrier is configured to hold the second workpiece above the heater, and wherein a diameter of the workpiece carrier is associated with the electrostatic clamping plate annulus. The annulus selectively electrostatically clamps the workpiece carrier or a circumferential portion of the first workpiece to its clamping surface, therein selectively maintaining a position of the first or second workpiece with respect to the annulus or non-electrostatic central portion.Type: GrantFiled: June 7, 2011Date of Patent: August 5, 2014Assignee: Axcelis Technologies, Inc.Inventors: William Davis Lee, Gary M. Cook, Perry J. I. Justesen, Ashwin M. Purohit, Robert D. Rathmell, Allan D. Weed

Patent number: 5251301Abstract: A system for simultaneously using a video signal to provide a video picture and computer data. At the transmitting end, a video signal is digitized and then modified by substituting digital signals representative of computer data for those representative of video pixels. The modified signal is reconverted to an analog signal and transmitted to a receiver. The receiver displays the video picture corresponding to the modified signal and extracts the computer data so that they may be provided to the computer. The computer can thus be controlled by the computer data as the video picture is being displayed.Type: GrantFiled: May 22, 1992Date of Patent: October 5, 1993Assignee: PC Connection, Inc.Inventor: Gary M.
