Title: Apparatus and method for allowing an operating system to persist across a power off/on cycle
Inventor: LESZCZYNSKI LARRY M
IPC: G06F9/445
Filed: 1996-07-23
Granted: 2000-11-07
Abstract: A method of allowing an operating system of a computer system (20) to persist across a power off and on cycle is described. The method includes the step of detecting if the computer system (20) is to be powered off (51). If the computer system (20) is dectected to be powered off, the state of the computer system (20) is then preserved by storing data representing the state of the computer system (20) in a designated area of a nonvolatile memory (23, 54). A system initilization code of the operating system is then replaced with new system initialization code that branches to restart code that accesses to the designated area of the nonvolatile memory (23, 55) such that when the computer system (20) is again powered on, the restart code accesses the designated area of the nonvolatile memory (23) for the data to restore the computer system (20) to the state before it was powered off.

Title: Apparatus for radio-frequency bonding of thermoplastic members
Inventor: RIEGERT RONALD JACK
IPC: B29C59/02
Filed: 1997-12-09
Granted: 2003-12-16
Abstract: A bonding apparatus for bonding a thermoplastic pad (38) having a predetermined peripheral shape to a first surface of a carpet (c) using radio frequency energy includes a die electrode (22) and a backing electrode (14).

Granted: 2004-11-30
Abstract: An inlet conveyor for conveying tires through a tire uniformity testing syst em includes a tire centering mechanism and a pair of conveyor belts for delivering tires to a tire testing station. A fixed conveyor having rollers on which tires can easily slide is secured to a frame that supports the centering mechanism. The conveyor belts are reeved around respective pulleys and are supported by support rails fixed to and extending away from the centering mechanism in cantilever fashion. A conveyor elevator is raised or lowered with respect to the frame unit to raise or lower the support rails and conveyor belts to either engage or disengage a tire resting on the fixed conveyor. The support rails and conveyor belts are adjustable in a lateral direction t o vary the width of the space between the belts to accommodate different size tires. The conveyor belts are advanced by a rotary pneumatic actuator that precisely controls the distance the belts move to position the tire with respect to the testing station. The inlet conveyor is mechanically isolated from the testing station so that disturbances affecting the inlet conveyor are not transmitted to the testing station. The inlet conveyor is movable with respect to the testing station to reverse the direction of tire flow through the testing machine.

The core has a higher refractive index than said inner cladding, said inner cladding having a higher refractive index than said intermediate cladding, and said intermediate cladding having a higher refractive index than said outer cladding. The inner cladding has a fairly high refractive index to limit the numerical aperture (NA) of said core. The inner cladding is within said intermediate, larger, cladding which is made of glass, that is used to guide multimode, high-power pump, said inner cladding acting as an intermediate level between said core and said multi-mode pump guiding intermediate cladding, with said outer cladding being present in said optical fiber for allowing said intermediate cladding to guide the pump power properly. The outer cladding is made of glass or of a low-index polymer material. The inner cladding is adapted to trap some of the pump signal into a smaller section in order to accelerate the absorption of the pump power.

Abstract: A method of producing high quality optical surfaces is disclosed. The invention allows for the production of optical surfaces with complex geometry while retaining the high quality of the optical surface. A top layer is provided on a substrate. In order to adhere the top layer to the substrate, an adhesion layer is applied first. In the preferred embodiment, the substrate is an aluminum substrate, the adhesion layer includes a layer of zinc and a layer of nickel and the top layer is gold. The substrate is generally stress free in order to provide a flat surface with no undulations. This allows a relatively thin layer of gold to be applied which then can be diamond turned in order to achieve a reflective layer.
