Abstract: A technique is provided to measure an alignment of an imaging device of a guided projectile containing an imager and a world coordinate frame, and includes producing a pure rolling motion of a body of the projectile, capturing a series of images of an imaging device calibration target over a range of body roll angles of the rolling body, measuring the roll angles of the rolling body with respect to a world coordinate frame as defined by the imaging device calibration target, simultaneously estimating alignment angles of the imaging device and misalignment angles associated with an orientation of the body, and estimating a rotational transform between an imaging device coordinate frame and a body coordinate frame based on the estimated alignment angles and misalignment angles.

Abstract: Mitigating whirl flutter in a tiltrotor aircraft includes providing at least one control surface supported for movement relative to a pylon attached to the aircraft's wing; providing an actuator for moving the control surface relative to the pylon; providing at least one sensor system to sense at least one deformation mode of the wing tip; providing a control system having one or more inputs and one or more output signals; using an electrical signal relating to deformation of the wing tip to serve at least as the basis for at least one of the inputs to the control system; determining at least one output signal of the control system based at least in part on the electrical signal relating to deformation; and controlling the actuator based at least in part on the output signal of the control system to move the control surface so as to counteract the deformation.

Abstract: Quantum networking systems and methods for routing entangled photons pairs are described herein. One quantum networking system includes entangled photon sources which generate entangled photons; optical output ports; a reconfigurable switching network connecting to the entangled photon sources and the output ports, which include a regular repeating structure of optical crossbar switches and interconnections for selectively routing individual ones of entangled photons pairs input to the network to and amongst the outputs; and a control module. The control module is configured to receive a request for entangled photons at the output ports; execute a routing algorithm to determine the state of the switches in the reconfigurable switching network to satisfy the request; and generate and transmit control signals to the switching network in order to set the states of the switches according to the executed routing algorithm. The reconfigurable switching network may be a Beneš or a banyan-type network architecture.

Abstract: A Vivaldi antenna having an upper conductor and a lower conductor. A signal connector feed is attached to a rear end of the conductors while each conductor includes a curved flare section extending forwardly for the reception or transmission of the signal. Each conductor includes elliptical loading section or sections disposed around its flare section to enhance performance of the antenna by improving the front to back ratio as well as other factors for the antenna.

Abstract: A jacketed structure includes at least one penetrator slug; a jacket surrounding the at least one penetrator slug; and a deformable sleeve surrounding a portion of the at least one penetrator slug and encased by the jacket. The deformable sleeve includes porous material, which absorbs plastic deflection of the jacket during an engraving process with a barrel of a weapon during firing. The at least one penetrator slug includes material having a hardness value greater than a hardness value of the jacket and the deformable sleeve. The deformable sleeve surrounds a rear portion of the at least one penetrator slug. The deformable sleeve surrounds approximately half of the at least one penetrator slug. The deformable sleeve is configured to deform symmetrically during firing of a weapon containing the jacketed structure.

Abstract: A flexible optical filter and a method of manufacturing includes providing a porous optical filter; depositing the porous optical filter onto a substrate; coating the porous optical filter with a polymer film thereby transferring the porous optical filter to the polymer film; and removing the polymer film and attached porous optical filter from the substrate thereby creating a flexible optical filter. The porous optical filter includes nano-structures. The nano-structures include any of rods, helices, particles, and zig-zags. The removed polymer film and attached porous optical filter may be flexible. The flexible optical filter includes inorganic materials. The nano-structures may absorb an applied strain to the flexible optical filter. The nano-structures prevent the inorganic materials from being damaged upon undergoing strain. The method may further include integrating any of nano-plasmonics, electrochromic, gasochromic, thermochromic, and non-linear optic materials with the porous optical filter.

Abstract: A pyroelectric device having a substrate and a first electrode overlying at least a portion of the substrate. A plurality of spaced apart nanometer sized pyroelectric elements are electrically connected to and extending outwardly from the first electrode so that each element forms a single domain. A dielectric material is deposited in the space between the individual elements and a second electrode spaced apart from said first electrode is electrically connected to said pyroelectric elements.

Abstract: A sintered cemented carbide body including tungsten carbide, and a substantially cobalt-free binder including an iron-based alloy sintered with the tungsten carbide. The iron-based alloy is approximately 2-25 % of the overall weight percentage of the sintered tungsten carbide and iron-based alloy. The tungsten carbide may be approximately 90 wt % and the iron-based alloy may be approximately 10 wt % of the overall weight percentage of the sintered tungsten carbide and iron-based alloy. The tungsten carbide may comprise a substantially same size before and after undergoing sintering. The iron-based alloy may be sintered with the tungsten carbide using a uniaxial hot pressing process, a spark plasma sintering process, or a pressureless sintering process. The sintered tungsten carbide and iron-based alloy has a hardness value of at least 15 GPa and a fracture toughness value of at least 11 MPa√m.
