  • Patent number: 10349180
    Abstract: A shallow speaker and a method of manufacture for the shallow speaker. The method of assembly uses two different alignment jigs at two different stages of the assembly to ensure alignment of the speaker components. During manufacture, a subassembly of components is created in the speaker frame, and then removed along with the first alignment jig. A second alignment jig is then placed in the speaker, and the bobbin and voice coil added. The subassembly is then connected to the frame, and the voice coil connected to the external connection terminal. Finally, the cone and dust cap are installed.

  • Patent number: 10313517
    Abstract: The system allows a consumer to shortcut through a call queue to reach a human agent faster. For phone or voice-based calls that require a consumer wait on hold, the system can give that consumer an accurate estimate of the wait time and allow them to skip all or some of it. It does this by using automated processes to proactively dial and wait in those call queues, measuring their time in queue. A new consumer making an incoming call can then join the call queue occupied by of those automated processes, shortcutting the consumer past all or some of the wait time.

  • Patent number: 10290304
    Abstract: Audio objects are associated with positional metadata. A received downmix signal comprises downmix channels that are linear combinations of one or more audio objects and are associated with respective positional locators. In a first aspect, the downmix signal, the positional metadata and frequency-dependent object gains are received. An audio object is reconstructed by applying the object gain to an upmix of the downmix signal in accordance with coefficients based on the positional metadata and the positional locators. In a second aspect, audio objects have been encoded together with at least one bed channel positioned at a positional locator of a corresponding downmix channel. The decoding system receives the downmix signal and the positional metadata of the audio objects. A bed channel is reconstructed by suppressing the content representing audio objects from the corresponding downmix channel on the basis of the positional locator of the corresponding downmix channel.
