Patent number: 12212083Abstract: Various configurations of compressible electrical assemblies are disclosed herein. Each variation of the compressible electrical assemblies includes at least one dielectric, an inner conductor and an outer conductor. Each inner and outer conductor may be configured as a compressible contact. One embodiment of a compressible electrical assembly includes an inner compressible contact, and outer compressible contact and a dielectric disposed at least partially between the inner compressible contact and the outer compressible contact. Each compressible contact also has a divaricated-cut section with a plurality of cuts defined by at least one cut angle measured between a pair of opposing inner surfaces.Type: GrantFiled: November 9, 2021Date of Patent: January 28, 2025Assignee: CORNING OPTICAL COMMUNICATIONS RF LLCInventors: Donald Andrew Burris, Thomas Edmond Flaherty, IV, Daniel Michael Grabowski

Publication number: 20240000511Abstract: Methods and systems for tracking surgical tools in a three-dimensional (3D) space are described. An example method includes receiving image data captured by a single camera of a first surgical instrument, wherein the image data comprises a two-dimensional (2D) image of a second surgical instrument. Using a machine learning model, a three-dimensional (3D) position of the second surgical instrument is determined. The example method further includes determining a feature of the image data based on the 3D position of the second surgical instrument, and outputting an indication of the feature using a user interface.Type: ApplicationFiled: June 30, 2023Publication date: January 4, 2024Inventors: Peter Andrew Flaherty, Carlos Andres Uquillas Armas

Publication number: 20060097457Abstract: A segmented shaft seal is provided for circumferentially sealing an outer surface of a rotating shaft unit. The shaft seal includes a plurality of seal ring segments disposed within a housing having a circumferential spring holding the ring segments together. The ring segments further have lift grooves defined on the circumferential inner surfaces thereof to generate a radially outwardly directed lift force acting against the inwardly directed spring force. The lift grooves have a tapered profile radially and/or circumferentially to facilitate formation of the outwardly directed lift force as well as molding of the ring segments.Type: ApplicationFiled: November 5, 2004Publication date: May 11, 2006Inventor: Andrew Flaherty
