  • Narrowband IQ extraction and storage
    Patent number: 11303306
    Abstract: Capturing, extracting and storing narrowband IQ data for later processing enables timely and efficient analysis. As wideband capture of RF information includes noise and non-signal elements, the present invention detects, extracts and stores narrowband IQ signals for later assessment. By transforming a high-volume data stream to a collection of smaller narrowband signals with greatly reduced storage and on-board processing requirements the present invention facilitates the capability to analyze signals of interest in an otherwise denied environment.

  • ARTIFICIAL INTELLIGENCE ASSISTED SIGNAL SHAPING
    Publication number: 20210326725
    Abstract: The disclosed invention uses artificial intelligence (AI) algorithms for detecting and classifying radiofrequency transmissions to model and simulate an RF environment. AI or machine learning (ML) algorithms further assist in determining optimal modulation, bandwidth and center frequency placement of a transmit signal to either fully and efficiently exploit unused spectrum in the RF environment, or to camouflage the signal to evade detection, and therefore interception while providing enough fidelity to the receiver to remain detectable. Such signal shaping is done while maintaining small SWaP-C footprint for system component hardware.

  • AI GUIDED SPECTRUM OPERATIONS
    Publication number: 20210117809
    Abstract: An intelligent hierarchal agent structure responds to requests and inquires regarding a data environment by parsing the query to actionable sub-questions and assigning each to a primary agent. Upon examination of available data, the agent assesses whether the sub-question can be resolved or whether additional material is needed. In the later instance the agent seeks aid from subordinate or secondary agents which in turn seek aid of other agents in order to generate information as necessary to resolve to the question presented. Upon resolution of the question the output is placed in a common database which is continually monitored by each agent. Agents are engaged in parallel yet respond according to a hierarchal structure.

  • Remotely operated equipment coupler
    Patent number: 7311338
    Abstract: A modular chemical handling apparatus has a first component coupled to a second component. The first component is retained proximate to the second component by a locking mechanism. Fluid conduit connection devices and/or electrical connection devices in the first component are coupled to corresponding conduit connection devices and/or electrical connection devices in the second component by couplers. At least one laterally sliding lock shaft is employed for coupling the first module to the second module and for decoupling the first module from the second module. In one embodiment, counterweights are used to maintain the sliding lock shaft and each of the connection devices in the fully coupled position.

  • RETROSPECTIVE INTERFEROMETRY DIRECTION FINDING
    Publication number: 20210311156
    Abstract: Using captured and stored wideband historical radio frequency data bearing information to the source of a signal of interest achieved using as few as two receivers and a plurality of commutating antennas. Wideband IQ data streams are received at two or more receivers and stored for later analysis. A first receiver is coupled to a reference antenna and a second receiver is commutatively coupled to a plurality of commutating antennas. Later, streams of wideband IQ data are retrieved for a select period of time and synchronized. From these streams a signal of interest identified and synchronously sampled over an acquisition interval by each receiver. Phase differences of the signal at each of the plurality commutating antennas is measured enabling a determination of the bearing to the common signal of interest.

  • GPU ACCELERATED IMAGE SEGMENTATION
    Publication number: 20210118142
    Abstract: Data gathered from a continual data source is converted into an image and represented by a rectilinear grid defining a grid of pixels. Each pixel in each axis unit of one axis is examined in parallel using a graphic processor unit (GPU) to determine whether any pixels exceed a predefined threshold. Those pixels that exceed the threshold are identified as positive return pixels. Within each axis unit groups of positive return pixels are identified based on a first axis epsilon. Adjacent groups of positive return pixels are assembled by merging the axis units based on a second axis epsilon. Groups of positive return pixels grouped together according to the first axis epsilon and the second axis epsilon are classified and reported as a signal.

  • FAR-SOURCE POSITION DETERMINATION
    Publication number: 20230077420
    Abstract: Two receivers located within a region of interest that is sufficiently small as compared to a distance to a source of a signal can be considered a “point”. Signals received at that “point” are planar. Accordingly, any difference in the time of arrival of a signal from the source by one receiver as compared to another receiver located within that region stablishes a locus of points representing a distance between the receivers perpendicular to the vector pointing to the source. Using signals from multiple far sources multiple loci on which one receiver must exist as compared to the other receiver can be identified. The convergence of these loci identifies a relative position of one receiver from the other, and when the geospatial position of one receiver is known, so too is the position of the other receiver.
