    Abstract: False radar target detection incudes: generating a pair of entangled photons as a probe photons and idler photons; preparing a plurality of photon states; using the ancilla photon states to encode the probe photons and the idler photons; encoding the probe photons and the idler photons with the ancilla photon states; storing the idler photons; transmitting the probe and ancilla photons as a radar signal; receiving a return radar signal from the target; performing a quantum error detection on the return radar signal to determine whether there is an error in the received radar signal as a result of decoherence in the return signal; and correlating the probe signal, the idler states and analyzing the errors detected on the return radar signal to determine whether the target is a true target when there is low decoherence in the return radar signal.

    Abstract: An EO/IR optical imaging system comprises collection optics to collect light from a scene into a collimated or near-collimated space. An imaging detector is positioned at the image plane and configured to integrate incident light (radiant flux or photons) over an image frame and readout a sequence of pixelated images at a frame rate, said detector exhibiting a saturation threshold. To prevent saturation of the imaging detector, a MEMS MMA is positioned in the collimated or near-collimated space. A secondary detector (via a pick-off) samples light from the collimated or near-collimated space multiple times per image frame. A controller responsive to the sampled light commands a percentage of the mirrors to re-direct light incident on those mirrors to a light dump and commands the remaining mirrors to re-direct light incident on those mirrors to the imaging detector. Together the mirrors adjust a fraction of light reaching the imaging detector such that the integrated incident light for a given image frame is less than the saturation threshold.

    Abstract: An apparatus includes multiple patch antenna elements configured to transmit multiple electromagnetic beams in multiple beam directions. The apparatus also includes multiple inputs each configured to receive one of multiple input signals, where each input signal is associated with one of the electromagnetic beams. The apparatus further includes multiple phase-tapered splitters each configured to receive one of the input signals, divide the received input signal into a set of sub-signals, and provide a phase taper that adjusts phases of at least some of the sub-signals in the set of sub-signals. Different phase tapers are associated with different ones of the beam directions. In addition, the apparatus includes multiple 90° hybrid transformers each configured to receive sub-signals associated with different ones of the input signals, isolate the received sub-signals from each other, and provide the isolated sub-signals to one of the patch antenna elements.

    Abstract: A cover for an effector, such as a projectile, missile, or gun-launched effector, includes two parts that are translatable relative to one another, such that the cover separates in stages as the effector launches. The cover includes an outer cover portion that is made up of multiple outer cover segments that together define a central opening through which part of an inner cover portion extends. In a launch of the effector, the effector first makes contact with the inner cover portion. This pushes the inner cover portion forward, breaking the attachment with the outer cover portion, and allowing the inner cover portion to translated forward relative to the outer cover portion. As the inner cover portion translates forward relative to the outer cover portion, the inner cover portion eventually makes contact with the outer cover portion, with both being pushed forward, and separating from the launcher.

    Abstract: A two-phased liquid-cooled electrical power apparatus includes a plurality of cooling circuits that recirculate and transition respective engineered fluids between liquid and vapor states around closed-loop fluid paths to cool a plurality of devices. A portion of each fluid path is either integrated with or in thermal contact with its device. The engineered fluids are evaporated within the respective portions of the fluid paths to hold the operating temperatures at or near the respective and different phase transition temperatures. The cooling circuits may be used to maintain different operating temperatures of hollow primary and secondary winding coils in a power transformer, of parallel connect hollow winding excitation coils and a common magnetic core in an electrical reactor, of power semiconductor devices mounted on heat sink(s) in which the fluid paths are embedded or power semiconductor devices in which the respective fluid paths pass through the devices.

    Abstract: A method includes obtaining thermal energy from a structure to be cooled, where the structure includes micro-channels. The method also includes providing the thermal energy to a water-based polymer network, where the water-based polymer network includes a gel formed using a polymer and water. The method further includes generating one or more gases by heating the water-based polymer network, where generating the one or more gases includes releasing the water in the water-based polymer network to produce steam. In addition, the method includes passing the one or more gases through the micro-channels to remove at least some of the thermal energy from the structure.
