  • Patent number: 7073664
    Abstract: A self-illuminated storage and carrying case for storage and transportation of generally laminar stored objects is described. The case includes at least one, but usually several, storage sheets, each sheet having pockets which are generally inclusive of the outline of the stored objects and adapted to retain the objects securely and in position. The pockets are adapted to allow any matter printed on the stored object to be read. Each sheet is secured by one edge into a cover having a front and back portion, and is retained between the front and back covers. On the non-secured edges of at least some of the sheets, illuminating elements having a generally cable-like form factor are affixed. The illuminating elements may be electroluminescent filaments, fiber optic strands, or other illuminating elements of similar form.

  • Patent number: 7040831
    Abstract: An improved design of positioning mechanism, mountable to an upright, allows smooth, readily accomplished adjustment of the angular, rotational and translational positions of a boom with respect to the upright. A hub is mounted to and rotatable with respect to a base. A friction plate between the base and the hub applies frictional forces that are established by the mechanism, by urging the hub and base together. A pressure sleeve partially contained in a matching opening in the hub controls the rotational and longitudinal movement of the boom with respect to the hub. The design of the frictional engagement surfaces allows adjustment of the resistance to movement of the boom in the angular, rotational and translational directions to extend smoothly and predictably from a condition of virtually no resistance to a completely locked and rigid condition.

  • Patent number: 5500618
    Abstract: A novel compensation device for conditioning or generating signals to have an arbitrarily defined shape, produced to an arbitrarily specified accuracy. The device comprises a plurality of bounded polynomial function generators having outputs summed into a summing network to produce a signal which is the composite of the effects of all of the polynomial generators. Accuracy is achieved through the use of fusible link trimming of the compensation circuits, which are configured to provide mathematically well-behaved polynomial functions with predictable responses to the programming, and which produce effects only over desired segments of the range of interest. The result is a monotonic signal with no discontinuities, which can be made arbitrarily close to a specified signal.

  • Patent number: 5105932
    Abstract: A precision magnetic manipulator for use in positioning targets, and the like, within a vacuum chamber, employs separate mechanisms for linear and rotational motion and makes them substantially independent. Ball or roller style bearings support a square, linear shaft within a housing, at least one set of bearings being at the point at which the shaft exits the housing, and another set being within the housing along the route of travel of the linear shaft, so that the shaft is fully being supported over the entire travel length. A magnet carriage supporting high-strength magnets, one system being optimized for rotational motion and the other being optimized for linear motion, couples to magnet followers within the housing, thereby providing rotational motion and linear motion which can be used in combination or separately, giving great freedom of movement within the vacuum chamber.

  • Patent number: 4815619
    Abstract: A medicament vial safety cap which may be formed integrally at the time of manufacture of the medicament vial or added as an accessory to an existing conventional medicament vial allows an equalization of pressure to occur within a chamber adjacent to the stopper of the vial so that aerosolization of medicaments does not occur as a hypodermic needle is inserted or withdrawn from the vial. A hydrophobic filter, communicating between the vial safety chamber and the ambient, allows the pressure equalization to occur while trapping molecules of medicament inside the chamber.

  • Patent number: 4800754
    Abstract: A fluid bypass type flowmeter has a main passage which is configurable to various effective diameters by selectably adding pre-defined additional cross-sections comprised of an adjustable laminar flow element located within a bore for fine adjustm=ent of the full-scale range of the flowmeter, and an adjustable restriction secondary passage for crude adjustments of the range of the meter. With adjustment of the flowmeter, all or a selected portion of the flow to be measured can be diverted through the secondary passage, where a flow measuring device is located, thereby allowing the flowmeter to operate at or near its full scale and thereby improving the accuracy of the flowmeter over various ranges of flow rate. A laminar flow element is employed in the main passage so that the pressure drop across the element varies linearly with flow rate and, accordingly, the ratio of diverted to un-diverted flow is a constant ratio even though the flow rate varies.

  • Patent number: 4777471
    Abstract: An improved circuit, and an improved device geometry for trimming element values in an integrated circuit employs selectable short-circuiting of fusible elements by means of application of a prescribed sequence of electrical waveforms of prescribed amplitude and polarity. The improved trim circuit configuration offers the possibility of improved trim circuit density by allowing selection of three trim elements from a single contact pad, in conjunction with a common contact pad, for each trim circuit. Replication of the circuits allows extension of the range of adjustment or of the resolution of the trim, at the expense of only one additional pad per each additional trim circuit. A unique device geometry is described for implementing the improved trim circuit within a single isolation pocket of an integrated circuit.

  • Patent number: 4692608
    Abstract: A compact optical imaging system with application to a viewing head of an endoscope. A lens assembly gathers and focuses light into parallel rays which are turned from the lens assembly optical axis. A planar image sensor is oriented parallel to the lens assembly optical axis and receives the light which has been turned. The light enters a glass plate serving as the back side of the image sensor and impinges on active light-sensitive elements on a silicon layer deposited on the glass plate. A substrate is bonded on the silicon layer and supports circuitry for buffering and driving signals to and from the image snsor. The substrate has a plurality of slots aligned with the bonding pads of the image sensor to permit electrical connection between the buffering and driving circuitry and the image sensor.

  • Patent number: 4667229
    Abstract: A color video endoscope system having a control unit compatible with various endoscopes. Each endoscope generates unique signals to the control unit to optimize the clocking out of data from the solid state image sensor, to optimize the processing of data received from the image sensor, and to identify the size and location of the image formed on the image sensor so as to control the image formed on the monitor. The control unit generates alternating fields of red, green and blue light through the endoscope light guide with blank fields between the color fields, during which time data is clocked out of the image sensor, thereby preventing image "smear" caused by immediately successive color fields.
