  • Patent number: 11200292
    Abstract: Embodiments seek to improve prefetch hinting by using automated browsing clusters to generate and update hinting models used for machine-generated hints. For example, hinting machines can include browsing clusters that autonomously fetch web pages in response to update triggers (e.g., client web page requests, scheduled web crawling, etc.) and generate timing and/or other hinting-related feedback relating to which resources were used to load the fetched web pages. The hinting machines can use the hinting feedback to generate and/or update hinting models, which can be used for machine-generation of hints. Some embodiments can provide preliminary hinting functionality in response to client hinting requests, for example, when hinting models for a requested page are insufficient (e.g., unavailable, outdated, etc.). For example, without having a sufficient hinting model in place, the hinting machine can fetch the page to generate preliminary hinting feedback, which it can use to machine-generate preliminary hints.

  • Publication number: 20210379264
    Abstract: A blood filtration system can reduce the amount of plasma constituents (e.g., water and/or electrolytes) in the blood of the patient, and accordingly increase the hematocrit value of the patient. The blood filtration system (e.g., a controller, or the like) can determine a hematocrit value of a patient. The blood filtration system can determine a venous pressure of vasculature of a patient. The blood filtration system can compensate for pressure head in a component of a blood circuit (e.g., a withdrawal line of a catheter), for example to improve the accuracy of the venous pressure determination. The blood filtration system can determine one or more resistance characteristics of a blood circuit for the blood filtration system. The resistance characteristics can correspond to a resistance to a flow of blood through a component of the blood circuit.

  • Publication number: 20210379262
    Abstract: A blood filtration system may to couple to an infusion pump that is external to the blood filtration system. The blood filtration system may include a blood circuit, for instance a variable-volume blood circuit. An infusion port may be in communication with the blood circuit and may receive an infusion fluid pumped by the infusion pump. A filtration pump may extract a filtrate fluid from a filter. The filtrate fluid may include filtered plasma constituents. A fluid characteristic sensor may measure one or more of pressure or flow rate of the infusion fluid pumped by the infusion pump. A controller may monitor the fluid characteristic sensor to determine a change in the pressure or flow rate of the infusion fluid. The controller may modulate a speed of the variable-speed filtration pump based on the change in the pressure or flow rate of the infusion fluid.

  • Publication number: 20210346651
    Abstract: A portable arm support can be secured to an arm of a patient, for instance during a medical procedure (e.g., filtration of blood of the patient). The arm support can inhibit movement of the arm of the patient in one or more degrees of freedom (e.g., elevation, abduction, adduction, flexion, or the like). In some examples, the arm support includes a cuff and abase. In another example, the arm support includes an elongated member. In yet another example, the arm support includes a constricting band. The arm support can help maintain blood flow in the arm of the patient, and can help protect a catheter inserted into the arm of the patient (or protect other medical equipment proximate to the patient).

  • Patent number: 10965683
    Abstract: Systems, methods, and apparatuses for authenticating requests to access one or more accounts over a network using authenticity evaluations of two or more automated decision engines are discussed. A login request for access to a user account may be submitted to multiple decision engines that each apply different rulesets for authenticating the login request, and output an evaluation of the authenticity of the login request. Based on evaluations from multiple automated decision engines, the login request may be allowed to proceed to validation of user identity and, if user identity is validated, access to the user account may be authorized. Based on the evaluations, the login attempt may also be rejected. One or more additional challenge question may be returned to the computing device used to request account access, and the login request allowed to proceed to validation of identity if the response to the challenge question is deemed acceptable.

  • Publication number: 20210044669
    Abstract: Embodiments seek to improve web page loading time using server-machine-driven hint generation for based on client-machine-driven feedback. For example, client computers having page renderers are in communication with content servers and hinting processors. The hinting processors can use hinting feedback from multiple page rendering instances to automatically generate hints for optimizing loading and/or rendering of those pages. In some implementations, in response to page requests from the page renderers, content servers can request hints from hinting processors and send those hints to the requesting page renderers for use in improving the page loading experience. In other implementations, in response to page requests from the page renderers, content servers can instruct the requesting page renderers to contact an appropriate hinting processor and to retrieve appropriate hints therefrom for use in improving the page loading experience.

  • Patent number: 10583292
    Abstract: An implantable electronic neuromodulation system includes an implantable pulse generator comprising a controller and a memory. The memory is configured to store an emulated neurosensory signal representative of nerve traffic acquired from a patient equipped with an extra-aortic balloon pump counter-pulsation system or an intra-aortic balloon pump counter-pulsation system. A lead is coupled to the implantable pulse generator. At least one electrode is coupled to the lead. The at least one electrode is positionable in contact with or adjacent to at least one nerve that carries sensory information from baroreceptors. The controller is configured to stimulate the at least one nerve using the emulated neurosensory signal.

  • Publication number: 20190379726
    Abstract: Systems and methods are described for avoiding redundant data transfers using delta coding techniques when reliably and opportunistically communicating data to multiple user systems. According to embodiments, user systems track received block sequences for locally stored content blocks. An intermediate server intercepts content requests between user systems and target hosts, and deterministically chucks and fingerprints content data received in response to those requests. A fingerprint of a received content block is communicated to the requesting user system, and the user system determines based on the fingerprint whether the corresponding content block matches a content block that is already locally stored. If so, the user system returns a set of fingerprints representing a sequence of next content blocks that were previously stored after the matching content block.
