  • Patent number: 11992334
    Abstract: A system for monitoring a joint of a patient is described. The system includes at least one sensor configured to be coupled near the joint of the patient, the at least one sensor configured to sense one or more measurements of the joint. The system also includes a computing device comprising a digital processing device configured to receive the one or more measurements, determine one or more joint parameters based on the one or more measurements, generate a user interface for display, the user interface including a graphical representation of the one or more joint parameters. The digital processing device is also configured to compare the one or more joint parameters to a predetermined threshold and generate an icon for display within the user interface. The icon being generated in response to one of the one or more joint parameters exceeding the predetermined threshold.

  • Patent number: 11886206
    Abstract: A pressure regulator for a BOP stack includes a housing having an input port, an output port, and a pilot port and a regulator piston axially movable through the housing between an open position and a closed position. The regulator piston has an internal passage formed through its first axial end. When the regulator piston is in the open position, the internal passage is in fluid communication with the input and output ports. When the regulator piston is in the closed position, the internal passage is in fluid communication with the output port and fluidly isolated from the input port. A space with regulator fluid is also provided within the housing adjacent a second axial end of the regulator piston, opposite the first axial end, wherein the space is fluidly isolated from the input port and the output port in both the open position and the closed position.

  • Patent number: 11552896
    Abstract: Methods, systems, and devices for filtering network traffic from automated scanner are described. A device (e.g., an application server) may receive an activity message associated with an interaction with an electronic communication message and identify, from the activity message, at least a source identifier of the activity message and one or more attributes associated with the electronic communication message. The device may then add the activity message to a mapping of source identifiers and attributes associated with previously received activity messages and classify the activity message as being associated with an automated scanner based on a comparison of the received activity message to the mapping over a previous time window. Upon classifying the activity message, the device may transmit a classification result to an external server.

  • Publication number: 20210325915
    Abstract: A method of reducing hydraulic shock in a BOP system including a pressure regulator having an input port and an output port, and a regulator piston that moves between an open and a closed position based on a change in hydraulic pressure applied to the regulator piston via a pilot port. The method includes initiating a function, and monitoring the state of the function as it is carried out to predict when the function nears the end of its cycle. The method also includes, when the function reaches a predetermined state, adjusting the hydraulic pressure on the regulator piston via the pilot port to gradually move the regulator piston between the open to the closed position to reduce fluid flow through the fluid path in a controlled manner to reduce hydraulic shock.

  • Publication number: 20210300156
    Abstract: A sump for an evaporator is disclosed. The sump may comprise: a sump housing comprising an upper end and a lower end, wherein the upper end comprises an opening and the lower end comprises a floor having a drain; and a tray located within the opening, wherein the tray comprises a base and a plurality of partitions extending from the base towards the floor, wherein the plurality of partitions divide the sump housing into chambers in acoustic communication with one another via a gap at a distal end of each of the plurality of partitions, wherein each gap defines a spacing between the respective partition and the floor, wherein, when noise enters via the drain, the sump housing and tray reduce acoustic noise which exits the sump.
