Abstract: 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.

Abstract: A process for removing one or more unsaturated halocarbons from a halocarbon mixture comprising one or more unsaturated halocarbons and one or more saturated halocarbons, which process comprises contacting the halocarbon mixture with a mixture of a solid chemical oxidant and a solid support in the presence of water.

Abstract: 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.
