Abstract: A device, system, and method for incident air space management is provided. A system includes a controller and a signaling unmanned aerial vehicle (SUAV) associated with a public-safety entity. The controller dispatches the SUAV to a location of a public-safety incident and generates a restricted airspace boundary for airspace, associated with the incident, within which the SUAV operates. The controller activates a restricted airspace beacon of the SUAV that correlates with the restricted airspace boundary. The SUAV broadcasts the restricted airspace beacon, indicating the restricted airspace boundary, relative to a current location of the SUAV. The restricted airspace beacon is operational in at least two modes: a stationary incident mode, during which the SUAV and the restricted airspace boundary are stationary relative to a fixed location of incident; and a mobile incident mode, during which the SUAV and the restricted airspace boundary are mobile and tracking a moving incident location.

One method includes translating a received query into a profile comprised of at least a query type and a priority. The method further includes collecting, based on the profile, a first set of data items from a first data file storing data categorized as general public data and a second set of data items from a second data file storing data categorized as personal private information and applying an AI correlation engine to the second set of data items to determine PPI-agnostic relevancy indicators for PPI included in the second set of data items. The method further includes masking, based on the query cluster profile, the second set of data items by replacing the PPI included in the second set of data items with the PPI-agnostic relevancy indicators.

Abstract: A method and apparatus for adaptable phase training of high frequency clock signaling for data capture is provided. A state machine synchronizes a first selection signal to a delay multiplexer and a second selection signal to a digital block demultiplexer to sequentially select a targeted pair of the static storage elements for each of a plurality of phase-delayed data strobe clock signals. Read back data from an external memory captured by the static storage elements is compared to known valid data. The state machine determines which of the plurality of phase-delayed data strobe clock signals resulted in known valid data being captured by the static storage elements based on the comparison. The state machine selects one of the plurality of phase-delayed data strobe clock signals that resulted in valid data being captured as a read clock signal for a memory controller to capture subsequent read data from the external memory.
