  • Publication number: 20240378694
    Abstract: Systems are provided for generating training data from images that are obtained from image generators that are typically configured to only generate a single image per frame. The image generators are modified or otherwise controlled to generate two different images at different resolutions for each of a plurality of frames. The training data is created by pairing the low-resolution images and high-resolution images for common frames into training data set pairings. A super-resolution model is applied to the training data set pairings to create a trained super-resolution model.

  • Publication number: 20240277909
    Abstract: A medicament preparation system includes a water purification module and a medicament proportioning module that is interoperable with a replaceable fluid circuit. The fluid circuit includes a purified water inlet, a product medicament outlet, and a plurality of pumping tube segments. At least a first concentrate container is connected by at least a portion of the fluid circuit to the product medicament output and a first concentration measurement sensor station is positioned in a flow path. A controller is programmed to calculate iteratively a concentration of a first concentrate from the first concentrate container and the purified water from a signal generated by the first concentration measurement sensor station and to regulate one or both of a first pumping actuator engaged with the first pumping tube segment and a second pumping actuator engaged with the second pumping tube segment, responsively to the concentration of the first concentrate and water.

  • Publication number: 20240264212
    Abstract: A method of remotely determining an impedance of an earth connection (142) of a first electrical equipment (122) connected to a power supply network (300). The method comprises receiving (606), from a first measurement node (302) connected to the first electrical equipment, a first value of an insulation impedance of the power supply network and receiving (612), from a second measurement node (304) connected to the power supply network, a second value of an insulation impedance of the power supply network. The method further comprises calculating (614) the impedance of the earth connection of the first electrical equipment using the first value of the insulation impedance of the power supply network, the second value of the insulation impedance of the power supply network and a known impedance value of an earth connection (144) of the second measurement node.

  • Patent number: 11879582
    Abstract: A method and fluid connection system to fluidly connect a fracturing manifold to a fracturing tree. The method includes fluidly connecting a plurality of flexible flowlines between the manifold outlet of a fracturing manifold module and the fracturing tree such that fluid from the manifold outlet is distributed into the flexible flowlines and into the fracturing tree to avoid abrupt or right angle changes in direction in all fluid connections at the fracturing tree and between the manifold outlet and the fracturing tree. The fluid connection system includes a flow distribution block having a single inlet and a plurality of outlets, and distributes fluid flow between the single inlet and the plurality of outlets without abrupt or right angle changes in direction. The flexible flowlines have a first end fluidly connected to one of the plurality of outlets, and a second end fluidly connected to the fracturing tree.
