  • Patent number: 11136100
    Abstract: An inflatable mast couplable to an underwater vehicle includes a flexible material defining an interior volume, a head structure, and a spring coupled to at least one of the flexible material and the head structure. The flexible material is designed to be filled with air to form an inflated mast structure that extends away from the underwater vehicle. The head structure is disposed at a distal end of the inflated mast structure and in some cases has a rigid shape that forms a panel having an outer surface that is flush with an outer surface of the underwater vehicle, when the mast structure is deflated and stowed. The spring is designed to provide a tensile force on at least one of the flexible material and the head structure when the flexible material is inflated to form the mast structure. A system includes the inflatable mast and a pump.

  • Patent number: 11137472
    Abstract: Techniques are disclosed for determining AOA of one or more radar pulses received at a vehicle and originating from a source. The techniques are particularly well-suited to provide pilots with a more accurate determination of the azimuth angle to the radar source, although ground-based and water-based vehicles may benefit as well. Some embodiments discussed herein determine a true estimation of both azimuth and elevation angles, with reference to an aircraft's body-centered coordinate system, to the radar source. These parameters can also be used to determine a more accurate position on the ground for the radar source.

  • Patent number: 11139217
    Abstract: A method for modifying a portion of a substrate after production is described herein. The method can include diagnosing a circuit operation error causing a malfunction, identifying a first contact on the substrate, and connecting, electrically, the first contact to a second contact with at least one trace. The trace is done with a focused ion beam. The method can include diagnosing an error on an operative area of a post-manufacture circuit board causing a malfunction; introducing a metal precursor into a focused ion beam chamber; ionizing the metal precursor by contacting it with a gallium ion beam into a conductive metal and a further ion; depositing a first portion of a conductive metal onto a substrate to form a first trace; and forming the first trace between the operative area and a non-operative area thereby connecting the operative area and the non-operative area.

  • Publication number: 20210293526
    Abstract: A shearography system uses a Geometric phase or Pancharatnam-Berry (PB) phase element to shear an image. A PB phase element provides a non-dynamical phase change used for wavefront control and results in uniform half-wave of retardation. Geometric phase may also be utilized to capture snapshot phase-resolved wavefront measurements and shearograms via a focal plane array with micro-patterned linear polarizers of different orientations. Wavefront shape control arises when the local orientation of the retarding media is spatially varied. One or more PB phase elements can be flipped or rotated to perform multiple tasks depending on its orientation. Two PB elements can be used in succession in order to provide a variable purely spatial shift between interfering wavefronts. The spatial offset of the light exiting the second element can be adjusted simply by changing the spacing between the two geometric phase surfaces. In shearography, this corresponds to an adjustable shear length.

  • Publication number: 20210279620
    Abstract: A method and system is disclosed for determining a probability that an encountered platform was of a specific type given that a plurality of emitters exist on the platform and each emitter has a computed probability that it is of each of a set of types. A preprocessing stage operates on a description of the environment and determines the probability of a set of events that are independent of any observation. A runtime processing stage uses the terms computed in the preprocessing stage along with data assembled from a set of observations to determine the conditional probability that a particular platform type was the type encountered.

  • Patent number: 11087228
    Abstract: A generic online, probabilistic, approximate computational inference model for learning-based data processing is presented. The model includes detection, feature production and classification steps. It employs Bayesian Probabilistic Models (BPMs) to characterize complex real-world behaviors under uncertainty. The BPM learning is incremental. Online learning enables BPM adaptation to new data. The available data drives BPM complexity (e.g., number of states) accommodating spatial and temporal ambiguities, occlusions, environmental clutter, and large inter-domain data variability. Generic Sequential Bayesian Inference (GSBI) efficiently operates over BPMs to process streaming or forensic data. Deep Belief Networks (DBNs) learn feature representations from data. Examples include model applications for streaming imagery (e.g., video) and automatic target recognition (ATR).
