  • Patent number: 11369629
    Abstract: A heparin structure with increased anticoagulant activity and method of making the same are disclosed. A heparin sample is provided and treated with a heparan sulfate sulfotransferase in an enzymatic reaction to add sulfuryl groups from a sulfuryl group source to the heparin sample, resulting in a heparin structure having above about 8% more 3-O-sulfo groups relative to wild-type bovine intestinal heparin. The added sulfuryl groups modify the heparin structure and increase the sample's binding to antithrombin III and its anticoagulant activity to be more similar and a viable alternative to porcine intestinal heparin. The modified heparin exhibits an anti-FXa activity and an anti-FIIa activity greater than about 180 U/mg, and a ratio of the anti-FXa activity to the anti-FIIa activity of about 0.9 to about 1.1, consistent with U.S. Pharmacopeia (USP) heparin activity specifications.

  • Patent number: 11210336
    Abstract: Methods, systems, and products help users recall memories and search for content of those memories. When a user cannot recall a memory, the user is prompted with questions to help recall the memory. As the user answers the questions, a virtual recollection of the memory is synthesized from the answers to the questions. When the user is satisfied with the virtual recollection of the memory, a database of content may be searched for the virtual recollection of the memory. Video data, for example, may be retrieved that matches the virtual recollection of the memory. The video data is thus historical data documenting past events.

  • Publication number: 20210255903
    Abstract: Some embodiments provide a method for updating a core allocation among processes of a gateway datapath executing on a gateway computing device having multiple cores. The gateway datapath processes include a first set of data message processing processes to which a first set of the cores are allocated and a second set of processes to which a second set of the cores are allocated in a first core allocation. Based on data regarding usage of the cores, the method determines a second core allocation that allocates a third set of the cores to the first set of processes and a fourth set of the cores to the second set of processes. The method updates a load balancing operation to load balance received data messages over the third set of cores rather than the first set of cores. The method reallocates the cores from the first allocation to the second allocation.

  • Publication number: 20210137439
    Abstract: Multiple circuits in a computing device can share one or more conductive elements. The use of the conductive element can vary by circuit, such as an antenna radiator for a radio frequency (RF) circuit or an electrode for an electrocardiography (ECG) circuit. The circuitry sharing a conductive element can utilize signals obtained over different frequency ranges. Those ranges can be used to select decoupling circuitry, or elements, that can enable the respective circuits to obtain signals over a respective frequency range, excluding signals over one or more other frequency ranges corresponding to other circuitry sharing the circuit. Such an approach allows for concurrent independent operation of the circuitry sharing a conductive element.

A heparin sample is provided and treated with a heparan sulfate sulfotransferase in an enzymatic reaction to add sulfuryl groups from a sulfuryl group source to the heparin sample, resulting in a heparin structure having above about 8% more 3-O-sulfo groups relative to wild-type bovine intestinal heparin. The added sulfuryl groups modify the heparin structure and increase the sample's binding to antithrombin III and its anticoagulant activity to be more similar and a viable alternative to porcine intestinal heparin. The modified heparin exhibits an anti-FXa activity and an anti-FIIa activity greater than about 180 U/mg, and a ratio of the anti-FXa activity to the anti-FIIa activity of about 0.9 to about 1.1, consistent with U.S. Pharmacopeia (USP) heparin activity specifications.

  • Publication number: 20210068935
    Abstract: Methods, systems, and products monitor a person's regimen for medicinal and dietary restrictions. When the person's regimen requires a liquid medication or supplement, an oral instrument is commanded to dispense a dosage of fluid. The oral instrument stores a reservoir of the fluid. If the oral instrument is a spoon, for example, the spoon may automatically dispense cough syrup or other medicine. A toothbrush, likewise, may automatically dispense mouthwash. A sensor may confirm presence of the oral instrument in the person's mouth, thus ensuring the dosage of fluid is ingested.

  • Publication number: 20210004450
    Abstract: Methods, systems, and products authenticate users for access to devices, applications, and services. Skills of a user are learned over time, such that an electronic model of random subject matter may be generated. The user is prompted to interpret the random subject matter, such as with an electronic drawing. The user's interpretation is then compared to the electronic model of the random subject matter. If the user's interpretation matches the electronic model, the user may be authenticated.
