  • Patent number: 7298558
    Abstract: An electronically adjustable, combinational color filter device is provided for generating color light. Incoming light is split in a polarizing beam splitter/combiner into a first and a second element of light. One or more wave plates operate to modify the polarization state of the first element of light, and one or more dichroic reflective filters reflect portions of the first element of light having a predetermined wavelength. Similarly, one or more wave plates operate to modify the polarization state of the second element of light, and one or more dichroic reflective filters reflect portions of the second element of light having a predetermined wavelength. Reflected portions of the first element and the second elements of light are combined in the polarizing beam splitter/combiner to create color light.

  • Patent number: 7252263
    Abstract: Methods for configuring aircraft that may be implemented to integrate aircraft sonic boom constraint requirements with the design process for a supersonic aircraft, for example, to reconcile a target sonic boom constraint with the internal layout and balance of the aircraft during the design phase. The disclosed methods may advantageously be employed in one embodiment to allow a sonic boom-constrained aircraft design configuration solution to be reached that incorporates a desired sonic boom signature with the requirements of an internal configuration layout. Resulting aircraft configurations may be usefully employed for achieving sonic boom suppression on any type of supersonic-capable aircraft, for example, a civil supersonic business aircraft.

  • Patent number: 6836201
    Abstract: A mechanical actuator includes an annular electromagnet and a ferromagnetic plunger disposed within a bore of the electromagnet and slidable therein. A first permanent magnet is positioned outside of the bore and in facing relation to a first end face of the plunger, and a second permanent magnet is positioned outside of the bore and in facing relation to the second end face of the plunger. The plunger is slidable in the bore between a first position with the first end face adjacent to the first permanent magnet and a second position with the second end face adjacent to the second permanent magnet. Activation of the electromagnet with the current flowing in a first direction drives the plunger toward the first permanent magnet, where it is retained. Activation of the electromagnet with the current flowing in a second (opposite) direction drives the plunger away from the first permanent magnet and toward the second permanent magnet, where it is retained.

  • Patent number: 6765535
    Abstract: A monolithic semiconductor power device. The device is designed to produce high energy density and high power level RF/Millimeter wave radiation using the quasi-optical spatial power of an array (100) of small amplifiers (200) on a solid state wafer (300). Each cell (200) of the array (100) contains a reflection amplifier (206) that receives radiation and retransmits the signal back into the approximate same direction from which it was received. The radiation exiting from the array (100) is physically like a reflection that has been modified by the individual amplifier's characteristics. The exiting amplified radiation leaves the array (100) as a coherent wave front (110). The individual amplifier elements are fabricated on a monolithic solid state wafer (300). Rather than being diced into individual amplifiers, the elements are electrically connected together with proper biases and ground levels on the actual solid state wafer.

  • Patent number: 6750804
    Abstract: A system and method for detecting a target. The inventive method includes the steps of receiving a complex return signal of an electromagnetic pulse having a real and an imaginary component; extracting from the imaginary component information representative of the phase component of the return signal; and utilizing the phase component to detect the target. Specifically, the phase components are those found from the complex range-Doppler map. More specific embodiments further include the steps of determining a power spectral density of the phase component of the return signal; performing a cross-correlation of power spectral density of the phase component of the return signal between different antenna-subarray (quadrant channels); and averaging the cross-correlated power spectral density of the low frequency components. In an alternative embodiment, the cross-correlation is performed on the phase component of the range-Doppler map directly.

  • Patent number: 6737639
    Abstract: A method and system for maintaining uniformity in a FLIR display. During a one-time initialization procedure, a plurality of dynamic ranges are defined by covering a specific range of bucket fill levels when in a certain gain. To cover all dynamic ranges possible, a plurality of pairs of responsivity equalization (RE) calibrations (each pair producing a RE set of pixel gain corrections) are also accomplished in the same one time initialization period. A plurality of corresponding level equalization (LE) calibrations (each using the appropriate calibrated RE set and producing a LE set of pixel level corrections) for each anticipated dynamic range are made at every power-up initialization. Each of the calibrations is done with respect to a thermal reference source to produce a uniform scene at the desired bucket fill level.
