Abstract: The present disclosure is directed to a method and system for repairing a blade for a turbomachine that has been damaged due to foreign object impact. Machine learning algorithms are used to determine an amount of material to be removed from one or more damage locations and determine an amount of material addition to the damaged portion(s) and/or at other locations on the blade to keep the natural frequencies of the repaired blade within design limits during operation.

Abstract: An apparatus for gathering intelligence, surveillance and reconnaissance [ISR] in a hostile environment. The apparatus may be generally cylindrical to blend in with the environment, particularly with indicia which are visible to people viewing the apparatus. The apparatus may have a tinted skin which does not allow viewers to see inside. Inside the apparatus are one or more sensors which gather the ISR. The sensors may be disposed on a payload delivery mechanism having a first, retracted position inside the hollow body and extending outwardly through a port to a second position to deliver a payload to a hostile target. The sensor may be separable from the apparatus or may remain internal to the apparatus.

Abstract: An automated camera system and method are provided that are configured to search for an object emitting or reflecting a certain wavelength of light. The camera can be infrared, electro-optical, or otherwise. Image processing software is configured to isolate pixel groups in each image, wherein those pixel groups fit a wavelength or color patterns of an object being searched. The system also includes processing methods for determining the relative location of the object (GPS or other) based upon the location of the camera and the field of view of the camera. Materials can also be used to tag the object so that the object is easier to find in adverse lighting conditions. Alternatively, the tag can be a wavelength that only one group of searchers knows about, and hence the object can remain relatively hidden from others. The system can be readily mounted in an aircraft or other vehicle so that large areas can be scanned and searched.

Abstract: A multi-junction resistance strain gauge comprises a substrate; a sinterable ink deposited directly on the substrate forming a non-conductive pattern; a stripe pattern generated on the sinterable ink by sintering, the stripe pattern having one or more non-conductive gaps, the stripe pattern having a first electrical conductivity; a sintered bridge across each of the one or more gaps and providing electrical continuity through the stripe and across the gaps, each bridge having a second electrical conductivity which is lower than the first electrical conductivity. The substrate is a non-conductive material or a conductive material coated with a thin insulator on which the stripe pattern is generated. The sinterable ink is a silver ink. The first electrical conductivity and the second electrical conductivity comprise different electrical conductivity. The first electrical conductivity of the stripe is a factor of about 1.7 or more higher than the second electrical conductivity of the bridge.

Abstract: The present invention relates to radar systems and methods of using same that are more efficient than current radar systems and methods of using same. Such radar systems and methods of using same using employs a plurality of pluses is used to make a decision on the presence or absence of a target. Such radar system and method of using same is more efficient as the position and velocity of a potential target is carried over from pulse burst to pulse burst. Thus, the radar signal structure from the target is the same, which in turn results in a high cross correlation that can used to efficiently decide if signal return is from an actual target or is due to interference.

At least some of the quantum wells are disposed in a region of the first sub-solar cell, and have a thickness and a bandgap sized such that a bandgap in selected quantum wells are less than a bandgap of a material of the first sub-solar cell and greater than a bandgap of a material of the second sub-solar cell resulting in radiative coupling between the first sub-solar cell and the second sub-solar cell.

Abstract: A system for determining a position of a receiver from as few as two or three transmitters. The receiver may be stationary or moving with a known velocity. The system includes a receiver clock having a clock bias and a clock drift relative to a reference clock and may also include a motion sensor. A decoder receives transmitted signals from a number of transmitters and determine pseudo-ranges and transmitter frequencies therefrom and a processing unit receives the pseudo-ranges, the transmitter frequencies and the receiver velocity and determines the position of the receiver therefrom. When only two transmitters are available, the position of the receiver is determined dependent upon a known receiver clock drift. The system may also determine clock bias and, when three or more transmitters are available, receiver clock drift. The processing unit uses ranging and Doppler equations in combination, and may also use a measured velocity.

Abstract: An apparatus and method for securing a rivet to a plate having a frontside and opposed backside with tight clearance. A ductile rivet is inserted through a hole in the plate. The apparatus has a driver with a cone which intercepts a hollow, internally threaded shank of a rivet. An externally threaded fastener is inserted through the diver and threadably engaged with the rivet. The threaded fastener is rotated, compressively drawing the driver into and deforming the rivet circumferentially around the hole. A wrench may be inserted against the backside to hold the hat of the rivet in nonrotatable engagement, thereby enabling the threaded fastener to be axially drawn into the rivet in response to rotation of the threaded fastener relative to the rivet.

Abstract: A method for determining the likelihood that a pixel in a video image sequence represents true motion in the image. Light from a scene is captured to yield an original image having a sequence of frames. A prototype image is created from the original image as a geometrically accurate representation of the scene which is substantially free of contamination. A tilt variance-Gaussian mixture model and/or multi-variate Gaussian model, based upon optical turbulence statistics associated with the scene, is developed. Each pixel in the original image sequence of frames is evaluated against the prototype image using a probability density function, to yield a likelihood that the respective pixel represents true motion.
