  • Patent number: 8171986
    Abstract: An apparatus includes a foam metal panel heat exchanger core positioned in a duct, an inlet flow passage for directing a first fluid to the heat exchanger core, and an exit flow passage for directing the first fluid from the heat exchanger core, wherein the inlet flow passage is tapered relative to an inlet face of the heat exchanger core and the exit flow passage is tapered relative to an outlet face of the heat exchanger core. The first fluid has a substantially uniform flow distribution through the core. The inlet and exit flow passages can be adjacent to each other. The core can be formed of a compressed foam.

  • Patent number: 7623059
    Abstract: A disruptive media dispersal system for aircraft which absorbs and scatters directed energy weapon beams such as tracking lasers and high energy lasers (HELs) is disclosed. The system may include laser detectors, laser beam propagation disruptive media and a dispersal system. When attacked by a directed energy weapon such as a laser, the laser detector system or vehicle operator deploys the disruptive media. The disruptive media is released by a feeder and dispersal system into the air in the path of the tracking and/or HEL weapon. For example, the dispersal system may be located onboard the aircraft near the front of the fuselage.

  • Publication number: 20070106407
    Abstract: A tape course generator produces tape course definitions for use in programming a CNC composite tape lamination machine. The tape course generator includes a reference surface parameterizer that maps a contoured surface onto a parametric reference surface, and a reference plane instantiator that maps the reference surface onto a reference plane. The tape course generator also includes a tape boundary plotter that plots a tape boundary, and a boundary mapper that maps the tape boundary and a ply boundary into the reference plane. In addition, the tape course generator includes an intersection locator that identifies intersections of the ply boundary and the tape boundary, and a tape course delimiter that defines tape cuts and determines which points in the reference plane are within a tape course. Moreover, the tape course generator includes a tape course transformer that maps the defined tape course back onto the contoured surface.

  • Patent number: 7139674
    Abstract: Methods and systems for generating a curve that represents raw data are provided. In one embodiment, the system includes memory for storing a curve generation application program, a user interface, a display device, and a processor. The processor executes the stored curve generation application program and is coupled to the memory, the user interface, and the display device. The executed curve generation application program includes a first component that receives raw data and a second component that allows for the manual or default setting of a base value for defining weight values for each data point of inputted raw data. A third component generates a curve for representing the raw data based on at least a portion of the data points and the set base value. A fourth component outputs the generated curve to the display device.

  • Publication number: 20060155393
    Abstract: Disclosed herein is a method of converting a ladder logic routine into Boolean logic. Boolean representations of the ladder logic elements of the ladder logic routine are collected in respective logic expressions for each ladder rung of the plurality of ladder rungs defining the ladder logic routine. Boolean logic elements are then resolved from the logic expressions. The Boolean logic elements are then stored in a memory in an order in which the Boolean logic elements are resolved to express the ladder logic routine in accordance with an execution order of the ladder logic routine.
