Publication number: 20230248415Abstract: Described herein are methods and systems for using the treatment tip apparatuses and high-voltage connectors with robotic surgical systems. For example, retractable treatment tip apparatuses (e.g., devices, systems, etc.) including one, or more preferably a plurality, of electrodes that are protected by a housing (which may be retractable) until pressed against the tissue for deployment of the electrodes and delivery of a therapeutic treatment, are disclosed. In particular, these apparatuses may include a plurality of treatment needle electrodes and may be configured for the delivery of nanosecond pulsed electric fields. Also described herein are high-voltage connectors configured to provide high-voltage energy, such as nsPEF pulses, from a generator to the retractable treatment tip apparatuses.Type: ApplicationFiled: March 20, 2023Publication date: August 10, 2023Inventors: David J.

Patent number: 10374693Abstract: A method of coordinating reuse of spectrum in a communication system in which a communication node is configured to communicate with devices that are located in multiple regions is described. The method includes obtaining a maximum interference constraint, and determining respective conflicts lists for one or more individual regions of the multiple regions. The conflicts list for each individual region includes at least one other region of the multiple regions for which a pairwise interaction with the individual region violates the maximum interference constraint. Further, the method includes assigning spot beam colors to the multiple regions using the determined conflicts lists such that pairs of regions that violate the maximum interference constraint with respect to one another are assigned different spot beam colors. Still further, the method includes causing the communication node to configure multiple spot beams in accordance with the assigned spot beam colors.Type: GrantFiled: November 15, 2017Date of Patent: August 6, 2019Assignee: THE BOEING COMPANYInventor: Christopher J.
