  • Patent number: 5694151
    Abstract: A method and apparatus providing visual feedback to a computer user while dragging selected text is described. As its first step, the processing logic creates a text object from the selected text once the computer user has initiated a drag. Simultaneously, the selected text is visually de-emphasized. Secondly, the processing logic snaps the text object to the cursor so that the text object follows the cursor without obscuring text at the insertion point. Finally, when the computer user selects the final insertion point, the selected text is visually zoomed from the source location to the final insertion point.
    Type: Grant
    Filed: April 1, 1996
    Date of Patent: December 2, 1997
    Assignee: Apple Computer, Inc.
    Inventors: Robert G. Johnston, Jr., Scott Jenson
  • Patent number: 5598524
    Abstract: A method and apparatus for allowing selecting within a window on a computer system display within a first application program and moving that item to a second position on a display controlled by a file system manager. A file is created by the file system manager which is representative of the discrete data item selected and dragged. A representation of the data is provided on the computer system display, such as an icon specified by the application program from which the data originated and identifying file name.

  • Patent number: 4857884
    Abstract: A paging system in which a large number of paging amplifiers may be connected to a pair of signal and power carrying wires having insufficient capacity to carry operating power for the amplifiers. Each of the amplifiers has a local chargeable battery connected to receive charging current from the pair of wires and for operating the associated paging amplifier. Charging power is applied to the pair of wires for charging the batteries during intervals when no paging signal is being carried by the wires. The presence or absence of charging power is detected and the paging amplifiers disabled or enabled respectively in response.

  • Patent number: 4209550
    Abstract: Coated carrier materials are prepared by electrostatically attracting particles of a coating material to the surface of carrier cores and then heating the carrier materials causing the coating material to fuse to the carrier material forming an adherent coating thereon. The coating material is attracted to the carrier materials by (a) rolling carrier materials down an inclined plane while spraying the carrier materials with a coating material; (b) dropping carrier materials through a cloud chamber containing a cloud of coating material particles; and (c) solids blending a mixture of carrier materials and particles of coating material.
