  • Patent number: 5862381
    Abstract: A visualization tool for creating graphic displays of trace data produced by a parallel computer program execution monitoring system. The visualization tool contains a display monitor, possible input devices, a mass storage device, and a computer system. Trace data is converted into data structures and later pixel maps to ultimately generate processing activity diagrams for each processor in the computer system. If more than one processor is present, more than one processing activity diagram can be generated and simultaneously displayed on the same screen in form of strip graphs and for certain indicated time intervals. An average processor utilization diagram is then calculated and plotted on every processor activity diagram for comparison purposes. Browsing through these strip graphs all at the same time while comparing them against the average utilization graph will allow a user to easily redistribute workload if necessary and/or locate problem situations.

  • Patent number: 5744910
    Abstract: A focusing system for a helix TWT includes a polepiece structure for conducting magnetic flux to a drift tube of the TWT in a first general direction and conducting the magnetic flux from the drift tube in a second general direction perpendicular to the first general direction. Radially magnetized permanent magnets are disposed at outer portions of the polepiece structure and supply the magnetic flux. A first pair of the magnets have a first direction of polarity, and a second pair of the magnets have a second direction of polarity opposite to the first direction. An outer shell encapsulates the polepiece structure and the magnets, and provides a magnetic flux return path. An electron beam travels in the drift tube and the magnetic flux provides focusing for the electron beam.

  • Patent number: 5659671
    Abstract: The present invention provides an apparatus for displaying an image of an object, as illuminated by a light source, on a display within a computer graphics display system. The image is graphically represented by a mesh of polygons and each polygon within the mesh has a surface defined by a set of vertices. The vertices define the surface of the polygon. The apparatus includes a processor, such as a rasterizer, that is responsive to each set of vertices for rendering each surface within the mesh of polygons in response to ambient lighting to produce a number of initially rendered surfaces within the mesh of polygons. Phong shading is utilized by the present invention. The processor produces a specular highlight contribution for each surface within the mesh of polygons utilizing a halfway vector, pointing from each surface to a direction halfway between a light vector and a vector pointing towards a viewpoint, associated with a vector normal to each surface.

  • Patent number: 5650751
    Abstract: A high efficiency linear amplifier comprises an electron gun assembly having a cathode and an anode, the cathode being operable at a relatively high voltage potential relative to the anode to form and accelerate an electron beam. A control grid is disposed between the cathode and the anode, and is biased relative to the cathode for Class B operation. A high frequency input signal is applied to the control grid to density modulate the electron beam. A shadow grid may be disposed between the control grid and the cathode. A drift tube encloses the beam and includes a first portion and a second portion with a gap defined between the first and second portions. An inductive output cavity communicates with the gap, and the density modulated electron beam passed across the gap and induces an RF electromagnetic signal into the cavity. A multistage depressed collector accepts and dissipates the electrons of the beam which remain after transit across the gap.

  • Patent number: 5481814
    Abstract: A shoe upper is divided into front and back parts which are hinged together at the shoe sole. The hinge may comprise a creased part of the sole or a mechanical hinge. The parts are held in either an open position or a closed position by a tension spring or a rigid element. The spring and element are pivotally secured to the shoe sole so that their longitudinal axis will be above and extend across the rotational axis of the hinge when the shoe is flat. Additionally, the distance between their points of connection will be less than the corresponding length of sole between said points. This will provide a low stress open position and a higher stress closed position. The stress is created by tension in the spring or by the inherent resilience of the shoe sole counteracting the compression force caused by drawing together the points of connection when a user steps into the shoe.

  • Patent number: 5069470
    Abstract: An apparatus useful for cleaning the debris-laden transmission of an assembled bicycle having a bicycle frame, the transmission including chainrings and a free wheel gear cluster. The apparatus comprises a first reservoir adapted to be secured to the bicycle in proximity to the chainrings, the first reservoir including a first receptacle adapted to hold a quantity of liquid cleaning composition and to collect debris removed from the chainrings; and a second reservoir adapted to be secured to the bicycle separately from the first reservoir in proximity to the free wheel gear cluster, the second reservoir including a second receptacle adapted to hold a quantity of liquid cleaning composition and to collect debris removed from the free wheel gear cluster.

  • Patent number: 4192062
    Abstract: A floor plate assembly (11), for terminating flat flexible cables (22,22) at two bracket members (14,14) on the plate, is disclosed. The floor plate has adequate area to assure firm adhesive bonding to a floor (73), with flat flexible cables being laid over the plate. Protective flanges (29,29) are provided on a pair of complementary, temporary cover sections (26,26) and an optionally pivotable bracket member (44) to protect substantial lengths of cable from accidental cutting during carpet-laying operations. The plate and a permanent housing (72) cooperate to clamp the carpet (74) about the bracket members, without creating undue stresses on an adhesive bond between the plate and the floor during threaded attachment of the housing to the bracket.
