  • Publication number: 20220303186
    Abstract: Techniques are disclosed for coordinating state information between devices in a network of devices. In one example, a first user device can obtain event information identifying an event (e.g., triggering of an alarm) associated with another user device and state information identifying a state of the other device. The first user device can report the state and event information to devices in the network. Observers corresponding to each user device can identify the occurrence of the event corresponding to the event information for each user device. An action (e.g., output an audio chime) can be performed by each device with an observer that identifies the occurrence of the event corresponding to the event information for each user device.

  • Patent number: 11277463
    Abstract: Apparatuses, systems, and methods for a wireless device to perform data stall mitigation. The wireless device may establish, at an HTTP layer of the wireless device, a data connection over a first network interface of the wireless device. The wireless device may compare an available duration of data in a data buffer associated with the data connection to a first threshold and notify, in response to the available duration approaching the first threshold, at least one lower layer of the wireless device of an emergency deadline. At least one lower layer may perform one or more remedial actions to avoid and/or mitigate a data stall.

  • Patent number: 11115457
    Abstract: Apparatuses, systems, and methods for a wireless device to perform methods for mitigating HTTP transaction errors for a data connection. The wireless device may establish a data connection over a first network interface of the wireless device at an HTTP layer of the wireless device. A transport connection may support the data connections and may support multiple HTTP transactions. An advisory signal may be received at the HTTP layer and, responsive to the advisory signal including first information, the HTTP layer may determine that at least a portion of the HTTP transactions can be (safely) retried. The HTTP layer may terminate, without notifying the application layer, the portion of HTTP transactions and may initiate, via a second transport connection established over a second network interface, retries of the first portion of HTTP transactions.
