Abstract: A method for determining control and scheduling information of a network includes receiving a radio frequency waveform having scrambled downlink control information (DCI), performing a cell search to determine cell identity information, performing a beam search and beam detection to estimate a signal quality of the waveform, decoding scheduling information associated with the waveform, detecting a control channel encoded with an unknown identity based on the scrambling identity and extracting resource elements of the control channel based on the scheduling information, attempting to decode the control channel via a re-encoding technique that is tested for accuracy and, in response to accuracy testing not passing, via a blind scrambling seed recovery technique, recovering the DCI based on the re-encoding technique or the blind scrambling seed recovery technique, and obtaining the control and scheduling information from the DCI.

Abstract: A method for providing a self-reliant secondary network of communication nodes using resources associated with a primary network defining sector beams using corresponding resources including respective SSBs includes performing a beam search with respect to the sector beams, performing beam detection to detect neighboring beams among the sector beams, and performing geospatial beam selection to define a selected set of SSBs of respective ones of the sector beams as being geospatial white space unlikely to interfere with the primary network when utilized by the communication nodes in the secondary network. The method may further include performing power control with respect to the selected set of SSBs, and applying medium access control protocols to enable the secondary network to use the selected set of SSBs of the primary network.

Abstract: An example method for determining a physical cell identifier is provided. The example method may include receiving a first and second signal captures from wireless, cellular communication signals transmitted by a base station. The first signal capture being a portion of a first radio frame and the second signal capture being a portion of a second, subsequent radio frame. The method may further include aligning the first and second signal captures to determine a location of a start of a first symbol in each and decoding data within signal captures to generate a first capture grid and a second capture grid. The method may further include combining the capture grids into a resultant grid and determining a subset of possible physical cell identifiers based on a position of a selected reference symbol within the resultant grid to assist with determining a current cell identifier.

Abstract: The present invention is directed to a vascular blood containment that allows a user to determine whether a blood vessel has been accessed and which provides access to the vessel. The vascular blood containment device includes a compression seal having increased reliability. The seal permits the passage of gas but prevents the passage of liquid. A valve providing access to a blood vessel through the blood containment device is configured to conform to an inner profile formed around a bore of the distal end of the outer housing. The configuration of the device permits the blood containment chamber to fill properly when the distal end of the blood containment device is positioned below the proximal end of the device.

Abstract: An improved catheter includes a double spiral configuration of infusion holes around the circumference and along the length of the catheter which provides an improved lateral dispersion of a thrombolytic fluid to more completely and quickly lyse a clot through which the catheter is passing. The double spiral configuration consists of groups or sets of infusion holes, typically groups of four. The holes in each set are longitudinally spaced from each other at substantially regular intervals along the length of the catheter. Each successive hole in a given group is circumferentially spaced by an angular distance of about 90° around the circumference of the catheter relative to the immediately preceding hole. Each group of holes is circumferentially spaced or offset by an angular distance of between 1° and 89° relative to the immediately preceding group of holes. Typically, the angular spacing between successive groups of holes is 18°.

Abstract: An electronically controlled syringe system for connection to a balloon catheter or other balloon-type member and for monitoring, displaying and optionally recording inflation or deflation data when the syringe system is used to inflate or deflate the balloon of the catheter or other balloon-type member. A syringe having a barrel and a syringe plunger is selectively operable to increase fluid pressure applied to the balloon catheter or other balloon member by sliding the plunger further into the barrel. Positive pressure applied to the balloon catheter or member is released by withdrawing the syringe plunger toward the rear of the barrel. A piezoresistive semiconductor transducer placed in fluid communication with the fluid pressure applied by the syringe, senses the fluid pressure and outputs an electrical signal representative of that pressure.
