  • Patent number: 10623246
    Abstract: Systems and methods for device control by a natural language processing system are disclosed. A user may desire to utilize a voice-enabled device to associate an accessory device with a hub device without having to utilize third-party software associated with the accessory device and/or the hub device. The user may provide a user utterance to associate the accessory device with the hub device. Audio data corresponding to the user utterance may be analyzed and utilized to generate and send directive data to a third-party remote system to transition the hub device to a join mode. Upon association completion, audio may be output confirming that the association has been established successfully.

  • Patent number: 10523570
    Abstract: A method for shaping traffic from an egress port in a software-defined wide-area network (SD-WAN) involves obtaining a stored network bandwidth measurement of the network bandwidth between a source endpoint and a destination endpoint, obtaining a current shaping rate used by the source endpoint when sending data to the destination endpoint, obtaining an updated measurement of the network bandwidth between the source endpoint and the destination endpoint, wherein the updated measurement of network bandwidth is obtained from an SD-WAN controller, determining a new shaping rate based on the stored network bandwidth measurement, the current shaping rate measurement, and the updated measurement of network bandwidth, and configuring the shaping rate used by the source endpoint when sending data to the destination endpoint with the new shaping rate.

  • Patent number: 10438164
    Abstract: This disclosure describes interactive data processing systems configured to facilitate selection by a human associate of tentative results generated by an automated system from sensor data. In one implementation, an event may take place in a materials handling facility. The event may comprise a pick or place of an item from an inventory location, movement of a user, and so forth. The sensor data associated with the event is processed by an automated system to determine tentative results associated with the event. In some situations, an uncertainty may exist as to which of the tentative results accurately reflects the actual event. The system may then determine whether the event is to be merged with one or more temporally and spatially proximate events and, if so, the sensor data and tentative results for the merged event is sent to a human associate. The associate may select one of the tentative results.

  • Patent number: 10091078
    Abstract: A method for shaping traffic across a wide area network is disclosed. The method involves advertising a data rate limit across a wide area network (WAN) from a first node, measuring the rate of data received at a WAN interface of the first node, and, if the measured rate of data received at the WAN interface of the first node exceeds a maximum threshold, advertising a reduced data rate limit across the WAN, and, if the measured rate of data received at the WAN interface of the first node is below a minimum threshold, advertising an increased data rate limit across the WAN.

  • Publication number: 20170289018
    Abstract: A method involves setting a link aggregation control protocol (LACP) link state for all links in a first service node to STANDBY to put at least one multiplexer in the first service node in a WAITING state to disable frame collection at the redundant service node and setting the LACP link state for all links in a second service node to SELECTED to put at least one multiplexer in the second service node in a COLLECTING/DISTRIBUTING state to enable frame collection at the primary service node.

  • Patent number: 9718254
    Abstract: A gypsum board comprises a cover sheet and a gypsum layer disposed on the cover sheet. The gypsum layer comprises the reaction product of an isocyanate, water, and stucco. The isocyanate increases the moisture resistance of the gypsum board. A method of manufacturing the gypsum board comprises the steps of combining the isocyanate, the water, and the stucco to form a slurry, and applying the slurry to a cover sheet to form the gypsum layer on the cover sheet.
