  • Patent number: 10382092
    Abstract: A method, a device, and a non-transitory storage medium are described in which a full duplex system may use information from a user of the device as a basis to configure parameters of a dynamic range controller system. The parameters may include high pass filter values, compression values, and masking values. The full duplex system may use a pre-distortion filter for generating an estimated echo feedback reference signal. For generating the estimated echo feedback reference signal, the pre-distortion filter uses an echo coupled reference signal via microphone path as a reference signal, and an echo feedback reference signal via speaker feedback path as the input. An echo canceller of the full duplex system may use the estimated echo feedback reference signal, which takes echo path distortion into consideration, for cancelling both linear and non-linear echo.

  • Patent number: 10356587
    Abstract: A wearable device, such as a smartwatch, may be used to enable switching of network services between endpoints. The switching of network services may include transferring the telephone number associated with a user's account to a particular active device, selected from a number of possible devices, of the user. The switching may be based on a number of factors and coordinated through the wearable device. The factors may include, for example, the location of the user, the location of the user relative to the user's endpoints, user provided priority information, and/or other user-specified profile information relating to endpoint preferences.
