  • Patent number: 11947876
    Abstract: A method of modifying a CAD system model performed on a data processing system includes receiving a dataset of co-ordinates representing an article in 2d, or in 3d and receiving 2d or 3d constraints respectively, to be applied to any changes to the dataset of co-ordinates for the article. A modification to be applied to the dataset is received and combined with the relevant 2d and 3d constraints to produce a constrained modification for each of the article and associated article. The constrained modification is solved in 2d and in 3d to determine whether a solution exists in which all constraints are met. If the solve is successful, the constrained modification is applied to each dataset simultaneously and, updated datasets are stored. If the solve fails, the constraints may be reduced and the solve step repeated, or the process is terminated.

  • Publication number: 20230044684
    Abstract: Provided herein are methods of purifying a sample containing nucleic acids to obtain isolated nucleic acids of a desired size range and methods of sequencing nucleic acids of a desired size range. The methods include a) combining a nucleic acid-containing sample with a precipitation buffer in a container to provide a precipitation mixture in which the precipitation buffer comprises water, a buffer, a salt, and polyvinyl pyrrolidinone (PVP) and/or Ficoll. The methods also include precipitating the nucleic acids in the precipitation mixture to provide a precipitated nucleic acid portion and a remaining sample portion. The precipitated nucleic acid portion predominantly comprises nucleic acid molecules above a selected size cutoff value and the remaining sample portion predominantly comprises nucleic acid molecules below the selected size cutoff value. The methods also include separating the precipitated nucleic acid portion from the remaining sample portion.

  • Publication number: 20220405094
    Abstract: A frontend of a platform of a multiplatform system can be monitored for user input. Upon receiving a user input that includes particular content, a data object describing the context in which the user input was provided may be created. One or more automations may be selected from an automation database based on a similarity to the determined context. The selected automations can be automatically displayed for the user, thereby encouraging the user to leverage automations across multiple platforms without requiring the user to switch between different platforms and without requiring the user to learn or understand platform-specific automation engines.

  • Patent number: 11287831
    Abstract: There is provided an electrically-powered material-transport vehicle having a vehicle-charging contact on one side of the vehicle, and a second vehicle-charging contact on the opposite side of the vehicle. The vehicle has a load-bearing cap that covers the top of the vehicle, and a cap elevator for raising and lowering the cap. The cap can be raised and lowered to a transit position, a payload-engagement position, a charging position, and a maintenance position. In the transit position and payload-engagement position, the cap covers the vehicle-charging contacts so that they are not exposed. In the charging position, the cap is raised so that the vehicle-charging contacts are exposed. The vehicle can enter a charging-dock with the cap in the charging position in order to recharge the vehicle's battery.
