  • Patent number: 10113844
    Abstract: Embodiments disclosed include a system comprising a missile segment having an external surface conforming to a portion of an external surface of a missile body. The missile segment comprising a plurality of chemical plasma dispensing units (CPDUs) having a chemical plasma reactant (CPR). Each CPDU is addressable so that a group of selected CPDUs in an area is ignited simultaneously to cause a first reaction to push CPR particles into a flow stream surrounding the missile body. The CPR particles to complete a second reaction in the flow stream over a reaction time period to effectuate production of expanding hot gas energy caused by heating air in the flow stream and gaseous reaction products over the missile body to provide an amount of a steering force to change one or more of six degrees of freedom at a location on the body. A missile and method are also provided.

  • Patent number: 8923359
    Abstract: The presently disclosed technique presents laser-based method and apparatus for use in remote sensing. In general, objects within a field of view are lased by a long cavity laser apparatus. Returns are detected, captured, and processed to identify actual objects of interest. These can then be communicated to a user. Over time, the actual objects of interest can be auto-tracked.

  • Patent number: 8621999
    Abstract: An apparatus and method for generating a very bright white light source. The apparatus is a coruscative white light generator, comprising: a shaped charge liner; and a radial line-shaped charge that initiates coruscative reactions in the shaped charge liner. In one aspect, the method comprises initiating coruscative reactions in a shaped charge liner using a radial line-shaped charge. In another aspect, the method comprises subtending a significant portion of an observer field of view while denying said observer the ability to identify targets and/or aim optical devices through large area coverage of about 3,000 to about 5,000 Kelvin particles.

  • Patent number: 8433037
    Abstract: A technique for generating three-dimensional information using radio frequency modulated X-rays includes both a method and an apparatus. In a first aspect, the method includes modulating an X-ray signal with first and second radio frequencies; transmitting the modulated X-ray signal; receiving backscatter; and processing the received backscatter to range a target in the field of view. In another aspect, an apparatus includes a transmitter and a receiver. The transmitter is capable of: modulating an X-ray signal with first and second radio frequencies and transmitting the modulated X-ray signal into a field of view. The receiver is capable of receiving backscatter from the transmitted X-ray signal. Other aspects include variations on these. For example, some aspects are computer implemented, such as a software implemented method, a program storage medium encoded with instruction to perform such a method, and a computing apparatus performed to program such a method.

  • Patent number: 8411821
    Abstract: The present disclosure presents, in various aspects and embodiments, a 3D X-ray reflection microscopy imaging technique. Some aspects are directed to various embodiments of an apparatus for use in such a technique, such as an X-ray reflection microscopy imaging system. Other aspects are directed to various embodiments of a method for use in such a technique, like a method for generating an X-ray image that has a grayscale response proportional to range. Some, though not all, aspects of the technique are computer-implemented, and so include encoded program storage media, programmed computing apparatuses, and computer-implemented methods.

  • Patent number: 6297716
    Abstract: A switched frequency multiplier receives pulses of pump energy as an input signal. The input signal is transferred to within a housing having a first cavity tuned to the frequency of the pump signal and a second cavity which is tuned to a harmonic of the input signal and is enclosed within the first cavity. An outlet port couples the second tuned cavity to a waveguide which includes a Q-switch that can be turned on and off. The interior of the housing has a planar grid of layers which includes a layer of nonlinear material and a frequency selective layer. The frequency selective layer is transparent to the input signal but reflective to the harmonic output signal thereby trapping energy in the second cavity. The multiplier operates by receiving a pump pulse and storing the energy while the Q-switch is closed. When the Q-switch is opened near the end of the pump pulse, the stored energy is suddenly released to produce a relatively high energy harmonic pulse having a shorter duration than the pump pulse.

  • Patent number: 6281746
    Abstract: A microwave parametric amplifier uses a circulator to receive an input signal which is provided through a transfer port to an input signal resonant cavity. A pump signal, which is preferably a harmonic of the input signal, is received into a pump signal cavity which is defined by a barrier that is reflective to the pump signal and transmissive to the input signal. A non-linear medium is positioned within the pump signal cavity to produce carriers due to the energy of the pump signal. The input signal interacts with the carriers to produce an amplified input signal which is conveyed from the input signal cavity through the circulator to an output port of the circulator.

  • Patent number: 6265934
    Abstract: A Q-switched parametric cavity microwave amplifier has input and output ports for receiving an input signal and producing a switched amplified output signal. A pump signal, preferably at a harmonic of the input signal, is received through a pump signal port and provided to a pump signal cavity within a housing. The pump signal interacts with a non-linear medium to produce carriers. A frequency selective layer reflects the pump signal but permits the input signal to pass therethrough. The input signal interacts with the carriers produced in the non-linear medium to enhance the signal present within the resonant cavity for the input signal. This transfers energy from the pump signal to the lower frequency input signal. A Q-switch is positioned in series with the output waveguide to cause energy to be stored within the input signal cavity. When the Q-switch is opened, a pulse is produced representing an amplified version of the input signal.

  • Patent number: 5731752
    Abstract: A microwave signal frequency multiplier is used to produce a harmonic signal derived from a microwave pump signal. In a selected embodiment, a Ka pump signal is converted to a W band microwave signal. The frequency signal multiplier includes a housing having a signal input port and a harmonic signal extraction port. The interior of the housing comprises a pump signal cavity which is tuned to the pump signal. Within the pump signal cavity, there is provided a non-linear material which converts the pump signal to a harmonic, preferably a third harmonic, of the pump signal. A frequency selective barrier within the pump signal cavity defines a harmonic signal cavity. An extraction port is coupled to the harmonic signal cavity for removing the harmonic signal from the multiplier. The frequency selective barrier is essentially transparent to the pump signal but is reflective to the harmonic signal.
