  • Patent number: 12611278
    Abstract: A system and method for attaching a sterile drape to a C-arm of a radiography imaging system includes at least one drape secured to a surface of the C-arm of the radiography system, the at least one drape including a substrate, an attachment strip disposed on the substrate, and a release liner removably attached to the attachment strip opposite the substrate. The substrate includes indica thereon in the form of attachment instructions for the placement of the attachment strip in the proper location on the C-arm. The release liner is removed from the attachment strip and the attachment strip is placed or positioned on the C-arm where indicated by the indicia for properly and quickly attaching the drape to the C-arm. The indica can be located on the release liner, or on the substrate such as on an instruction liner attached to the substrate opposite the attachment strip, or directly on the substrate.

  • Publication number: 20250387901
    Abstract: Methods, systems, and apparatus, including computer programs encoded on computer storage media, for data-driven robotic control. One of the methods includes maintaining robot experience data; obtaining annotation data; training, on the annotation data, a reward model; generating task-specific training data for the particular task, comprising, for each experience in a second subset of the experiences in the robot experience data: processing the observation in the experience using the trained reward model to generate a reward prediction, and associating the reward prediction with the experience; and training a policy neural network on the task-specific training data for the particular task, wherein the policy neural network is configured to receive a network input comprising an observation and to generate a policy output that defines a control policy for a robot performing the particular task.

  • Publication number: 20250383279
    Abstract: A method of automatically identifying data quality issues in background data for laser diffraction-particle characterisation is provided. The method comprises receiving background data corresponding to light intensity measured by each of a plurality of detectors in a laser-diffraction-based particle size analysis system. A processor is used to automatically determine if the background data contains at least one artefact that is indicative of a source of error in the particle size analysis system. If the background data is found to contain at least one artefact an indication is provided that the background data contains at least one artefact. Furthermore, the at least one artefact is classified, and the classification is reported.

  • Publication number: 20250075751
    Abstract: Centrifugal clutch mechanisms, and transmissions and lawnmowers having centrifugal clutch mechanisms are provided. A centrifugal clutch mechanism includes a clutch bell comprising an annular wall and a circular ring extending away from the annular wall to define an internal cavity, wherein the circular ring comprises an inward facing surface defining a drive surface. The centrifugal clutch mechanism also includes a plurality of centrifugal weights disposed in the internal cavity and an inward biasing element engaged with the centrifugal weights. The inward biasing element biases the centrifugal weights towards a disengaged position in which the centrifugal weights do not interface with drive surface, and upon application of a sufficient centrifugal force, the centrifugal weights are configured to transition to an engaged position in which the centrifugal weights interface with the drive surface.

  • Publication number: 20240337166
    Abstract: A downhole valve apparatus, for controlling fluid flow in drilling operations, includes a tubular housing and a float valve movably held within a valve bore of the tubular housing and partially within a stress relief bore. The float valve is axially movable relative to the tubular housing while in a sealing relationship with the valve bore between a first configuration and a second configuration of the downhole valve apparatus. A valve member of the float valve allows a downward flow of a drilling fluid of a first pressure to flow through the float valve in the first configuration, and the valve member blocks an upward flow of any fluid of a second pressure from the well through the float valve in the second configuration.
