  • Patent number: 10771392
    Abstract: A computer-implemented system and method include a rate-limiting server. The server receives a request from a client and uses an early stage process to search for a rate-limiting token bucket (TB) using metadata associated with the request. Responsive to finding the TB using the first metadata, a response operation is performed. Responsive to not finding the TB using the first metadata, a late stage process is used to search for the rate-limiting TB using server-side session data associated with the request. Responsive to not finding the TB using the session data, the TB is created and associated with at least two search indexes comprising the first metadata associated with the request and the session data. Finally, the response operation is performed that comprises transmitting a determined response to the client.

  • Patent number: 10638356
    Abstract: A 5G network communicates per-slice constraints for QoS parameter values from a centralized unit (CU) to a MAC scheduler of a distributed unit (DU). The CU communicates these per-slice constraints, rather than or in addition to per-DRB constraints, to the MAC scheduler over the CU/DU interface. In some implementations, the CU/DU interface is an F1 air interface as defined in specification 38.473 in the 3GPP standard. In some implementations, the DU provides per-slice performance feedback over the CU/DU interface. Based on such feedback, the CU may adjust the per-slice QoS constraints.

    Abstract: An apparatus is provided for scanning and decoding barcodes in a tray or other container containing multiple items, such as tissue samples, that are identified with discrete barcodes. The apparatus includes an imager, a lighting system, and a processor. The imager is configured to capture images within a selectable field of view. At least a portion of a bulk sample container, which is configured to carry a plurality of sample/tissue containers, is positioned within the field of view. The lighting system is configured to evenly light the field of view. The processor is configured to receive the captured images from the imager. The processor is further configured to analyze a first image of the captured images and to detect and decode the barcodes present in the first image.

  • Publication number: 20190391861
    Abstract: Systems and methods for presenting collaboration activity to a particular user are disclosed. A method embodiment commences by recording event records that codify one or more event attributes corresponding to one or more content object access events. The content object access events are associated with two or more users that interact with the content objects. At a later moment in time, a subset of event records is selected, the selection being based at least in part on timestamps of the content object access events. A display order to apply to the selected subset of event records is determined, the order being based at least in part on timestamps of collaboration events arising from the users. Event messages to present in a user interface are generated, and the event messages are then displayed in the user interface in accordance with the display order.

  • Publication number: 20190325009
    Abstract: A multi-user collaboration system. User-specific change markings are applied to a collaboration object. The user-specific changes to be presented are time-oriented, based on a time of a last view of the collaboration object. A plurality of users that have access to the collaboration object are identified. Time-ordered versions of the collaboration object are captured. Each captured version corresponds to changes made to the collaboration object by any of the users. When a request to view the collaboration object is received from a subject user, a method determines the latest version of the collaboration object and also determines the specific last accessed version of the collaboration object that was seen by the subject user. The two versions are compared, and the comparison changes are used to generate user-specific change markings. The collaboration object with the generated user-specific change markings is presented by rendering the user-specific change markings on respective user-specific devices.
