  • Patent number: 10693919
    Abstract: Instead of utilizing a centralized server or hardware(routers/gateways) to enforce connectivity policy restrictions, the policy connectivity restrictions for media session traffic are enforced by an endpoint that is involved in the media communication. Based on the policy requirements, the client enforces the policy restrictions by restricting the candidates that may be selected for the establishment of the media path. For example, the enforcement may result in the client selecting a path from available candidates that avoids congested Wide Area Network (WAN) links, avoiding a low bandwidth link, or possibly even failing the communication completely. The clients may also provide periodic updates to the policy server to allow tracking of the utilization of managed WAN links.

  • Patent number: 10624032
    Abstract: A battery-powered mobile hearing assist device allows concurrent wireless transception of control data via standard Bluetooth low energy (“BLE”), such as a smartphone, and proprietary audio streaming (“PAS”) from a second device such as a wireless audio streaming accessory. Power savings are achieved particularly in situations where the hearing device is searching for the PAS device. Instead of performing PAS search events as a separate wireless activity from the BLE advertising or connection events, including waking and ramping up for each of the BLE and PAS protocols, PAS search events are combined into the BLE advertising or connection events before returning to the sleep mode in each connection interval, eliminating duplicative processor steps, ramp up and/or ramp down.
