  • Aircraft bypass duct heat exchanger
    Patent number: 11920517
    Abstract: A turbine engine heat exchanger has an array of heat exchanger plates mounted to an inner case wall for providing heat transfer from a bleed flowpath to a bypass flowpath. Each plate has: first and second faces along the bypass flowpath; a proximal edge mounted to the inner case wall; an inlet along the proximal edge; an outlet along the proximal edge; and a branch segment of the bleed flowpath passing from the inlet to the outlet.

  • Touch panel system and method for distinguishing multiple touch inputs
    Patent number: 7254775
    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.
