Patent number: 8047464Abstract: In a method and apparatus for controlling the deployment of a towline connecting a mooring craft to an ejected object comprising the steps of monitoring velocity to determine when a point for optimum braking has been achieved and then engaging a brake system to retard deployment of the towline, a DC motor augments and controls the brake system. The DC motor further controls the retrieval of the object. A cutter mechanism uses a first blade to grip the towing cable to maintain tension thereon as a second blade cuts the cable. A spring biased boom in combination with spring biased fins on the ejected object rapidly deploys the object from its storage housing. A locking mechanism secures the deployment mechanism in a stable locked position upon the object reaching its fully extended position.Type: GrantFiled: May 12, 2011Date of Patent: November 1, 2011Assignee: BAE Systems Information and Electronic Systems Integration Inc.Inventors: Christopher M.

Patent number: 6805314Abstract: A support assembly and method is provided for suspending lightweight tools or other objects, such as hairdryers and the like. The assembly provides support and in particular embodiments, electrical power to the object suspended. In addition, the assembly provides management of the cord. Elevation of the object may be adjusted within a predetermined range of motion. The assembly exerts an upward force on the object that varies depending upon the elevation. This variable force is calibrated to provide the object with a uniformly weightless or virtually weightless “feel” nominally throughout the range of movement. The assembly is provided with low friction and low inertia, so that an object may be rapidly and easily moved between various elevations with little effort and little drag. The amount of force exerted on the object by the assembly may be adjusted.Type: GrantFiled: April 7, 2003Date of Patent: October 19, 2004Inventor: Michael B. Hopper

Patent number: 6073878Abstract: A device and method for unwinding or winding a sawing wire from a reel or to a reel which rotates. The sawing wire runs from the reel or toward the reel over a pulley and in so doing, assumes a defined axial position on the reel. In the method, the reel is moved along its rotational shaft while the sawing wire is unwound or wound up. The sawing wire however remains aligned perpendicular to the rotational shaft of the reel in the region between the reel and the pulley. There is a pivot arm which is moved concomitantly by a carriage system. The pivot arm has an end piece connected to one of the clamping elements. Thus it is possible to move the pivot arm from a reel-holding position into a reel-release position.Type: GrantFiled: May 29, 1998Date of Patent: June 13, 2000Assignee: Wacker Siltronic Gesellschaft fur Halbleitermaterialien AGInventor: Karl Egglhuber
