Abstract: Touch panel systems and methods are disclosed that can distinguish temporally overlapping touch inputs from single touch inputs so that valid touch position coordinates can be determined. Touch panel systems and methods of the present invention can distinguish overlapping touches by comparing signal magnitudes to specified thresholds, by comparing the rates of change of signal magnitudes or measured positions to determined parameters, by locating the proximity a calculated location to icons or other such active areas, and the like. Because touch panel systems and methods of the present invention can discriminate single touches from double touches, they can be used in multiple user applications such as multiplayer games as well as in applications that may be subject to rapidly successive or overlapping touch inputs.

Abstract: Methods are provided for simulating a touch on a touch screen by applying a first signal to a first surface of the touch screen, applying a second signal to a second, opposing surface of the touch screen sensor, and changing the first signal relative to the second signal. Such methods can be used to simulate a touch to the center of the touch screen, for example. The simulated touch can be used in some embodiments to perform diagnostics and/or calibrations functions.

Abstract: An apparatus for the production of a jacket for a recording disk from a foldable blank, comprising a stationary receiving surface for one half of the blank and a further surface, pivotable essentially through an angle of 180.degree., for bending over the other half of the blank; a sheet-like spacer member which can be positioned over the stationary receiving surface, and one of whose edges, serving as a folding blade, is allocated to the swing point of the two said surfaces; and means for heating the fold area of the blank.

Abstract: Magnetic recording media in which, following application of the magnetic dispersion to a web of tape base material, the magnetic particles are oriented in a preferred direction and the magnetic dispersion is dried to fix the magnetic particles in their oriented position. To assist the orienting action of the orientation magnet, a blanket is located between the latter and the coating device, which blanket is caused to make sliding contact with the applied magnetic layer.

Abstract: A process for the manufacture of a jacket, comprising two cover sheets joined to one another, for a flexible disk for data recording, the cover sheets and the nonwoven lining being punched out in the form of blanks including the functional apertures, and the cover sheet blank and the nonwoven blank being joined to one another and then folded to form the jacket, wherein the sheet material for the cover sheets is transferred from a magazine, with the aid of mechanical, air-operated grippers provided with positioning means, to an assembly surface and is there provided, the sheet of nonwoven material from a second magazine is tacked onto the cover sheet material by spot-welding and is then joined thereto over the entire surface by thermal welding, thereafter the cover sheet material thus provided with the nonwoven covering is transferred to a holder frame and then conveyed, with this frame, to a punching device where it is punched out to form a blank provided with the functional apertures, subsequently the blank
