Publication number: 20080279671Abstract: A picking mechanism may include a mechanical reference system for establishing the approximate number of sheets that will be “picked” from a larger stack each time the picking process occurs. A pick moves toward the stack of paper to insert itself between two sheets of paper at a level in the stack that is determined by the place the pick resides relative to the stack. In the preferred embodiment, the pick resides at said position because it is positioned at a adjustably fixed relationship to a reference member and the reference member rests on the top of the stack of paper when the pick is in a retracted position. Thus, the vertical distance between the reference member (and the top of the stack) and the point (edge) of the pick determines how many sheets will be picked at a time.Type: ApplicationFiled: October 15, 2007Publication date: November 13, 2008Applicant: PERFORMANCE DESIGN, INC.Inventors: RALPH ALLEN, FRANK L. BAGROSKY

Patent number: 5784549Abstract: A method and system are disclosed for invoking a limited or "fail-safe" functionality from a computer system having a graphical user interface (GUI). In one aspect, a computer operating system having GUI functionality can be activated with two different sets of GUI features. Normally, the operating system provides a full complement of GUI features. Alternatively, the operating system provides a more limited set of GUI features. The operating system invokes the limited set of GUI features either in response to a user command, such as a keyboard function key pressed during the bootstrap loading sequence of the operating system, or automatically in response to a failure of an attempt by the computer system to load the normal complement of GUI functions. With the limited set of GUI features, the user of the computer can take advantage of the power of graphical user interfaces even when the computer system is not operating normally.Type: GrantFiled: February 6, 1997Date of Patent: July 21, 1998Assignee: Microsoft CorporationInventors: Brian Alan Reynolds, Pierre-Yves Santerre, Darryl S.

Patent number: 5760904Abstract: The present invention discloses a method and system for inspecting a surface of an object with laser ultrasound. In the present invention, the surface is scanned with a source laser emitting a laser beam at a plurality of scanning positions. The emitted laser beam generates surface or Lamb waves at the plurality of scanning positions and transmits the waves throughout the surface. The surface of the object is scanned with a detector laser emitting a laser beam onto the object surface at the plurality of scanning positions. Surface displacement produced by the waves reflected from the surface is detected with a detector at each scanning position. The detected displacement at each scanning position contains signals representing a laser ultrasound waveform data set corresponding to a two-dimensional surface region along the object. The laser ultrasound waveform data sets at each scanning position are processed with a synthetic aperture focusing technique in order to generate high resolution images.Type: GrantFiled: July 26, 1996Date of Patent: June 2, 1998Assignee: General Electric CompanyInventors: Peter William Lorraine, Ralph Allen Hewes

System and method for reducing stack physical memory requirements in a multitasking operating system
Patent number: 5727178Abstract: An operating system component allocates locked stack memory pages to threads on an as needed basis. Each thread has a permanent locked stack. A second locked stack page is mapped to each thread. If a thread is using the assignable locked stack page when the system scheduler switches away from that thread, the assignable stack page becomes owned by that thread. When the system scheduler switches to a thread the assignable stack page mapped to that thread is checked to see if it is owned by another thread. If so, an unowned assignable stack page is mapped to the thread prior to switching to that thread. The size of the pool of locked assignable stack pages is adjusted dynamically. If the number of unowned assignable stack pages exceeds a threshold, locked stack pages are released. If the number of locked assignable stack pages falls below a predetermined number, additional assignable stack pages are allocated.Type: GrantFiled: December 5, 1996Date of Patent: March 10, 1998Assignee: Microsoft CorporationInventors: Richard Allen Pletcher, Ralph Allen Lipe -
Patent number: 5675878Abstract: Apparatus to continuously draw, texture and warp polyester yam in which the texturing apparatus includes texturing balls mounted on a common mount for a plurality of texturing positions which individually can be rotated into and out of position without individual adjustment of each ball after rotation back into operative position.Type: GrantFiled: December 16, 1996Date of Patent: October 14, 1997Assignee: Milliken Research CorporationInventors: Robert Saul Brown, Ralph Allen Cantrell

Patent number: 5673533Abstract: The present invention provides an apparatus and method for testing seal strength and integrity of packages and for testing container and lid integrity, during an on-line production processing environment. Air pressure is introduced in a unique way to test the container and/or container seal in an additional step of an otherwise typical processing environment. A computer may be in communication with the testing sensors to control the processing in the event a failure is detected. The present invention provides a way to meet the continuously increasing line speed in form, fill and seal production processes with a unique ability of having complete package integrity testing for any odd shapes and package combinations.Type: GrantFiled: November 5, 1996Date of Patent: October 7, 1997Assignee: Abbott LaboratoriesInventors: Jianjun Wang, Billy Dean Cornelius, Ralph Allen Gygax

Patent number: 4942529Abstract: A travel speed limiting control system for lift trucks, particularly of the "orderpicker" type, having an extendible mast, is disclosed. The truck travel speed which the operator can command is limited by factors including load weight, load elevation, heading angle and direction of truck travel (forward or reverse) . Optionally, other factors may be involved, such as lateral tilt and load moment. An algorithm including the desired input factors is continually processed by an on-board microcomputer to provide an instantaneous speed limit signal. In addition to its normal operating mode, the microcomputer is also arranged to operate in a "learn" mode, whereby it runs through the ranges of various input signals and develops a set of stored values which indicate the allowable ranges of the inputs, as well as offset or bias values which compensate for manufacturing tolerances occurring in the components of the system.Type: GrantFiled: May 26, 1988Date of Patent: July 17, 1990Assignee: The Raymond CorporationInventors: Isaac Avitan, Ralph Allen, David L. Kellogg, Stephen L. Page, David J. Radley
