  • Publication number: 20200194021
    Abstract: Methods, systems, computer-readable media, and apparatuses for signal enhancement are presented. One example of such an apparatus includes a receiver configured to produce a remote speech signal from information carried by a wireless signal; a signal canceller configured to perform a signal cancellation operation on a local speech signal to generate a room response; and a filter configured to filter the remote speech signal according to the room response to produce a filtered speech signal. In this example, the signal cancellation operation is based on the remote speech signal as a reference signal.

  • Patent number: 10683459
    Abstract: Provided are a liquid-phase hydroisomerization system and a process therefor and use thereof. The system comprises a gas-liquid mixer (3), a hydroisomerization reactor (4) and a fractionating column (6). An oil product and hydrogen are mixed as a liquid hydrogen-oil mixture, and are introduced into the hydroisomerization reactor for a hydroisomerization reaction, and after being fractionated, a target product is led out. A supplemental hydrogen-dissolving inner member is provided at least between a group of two adjacent catalyst bed layers in order to supplement hydrogen to the reactants. The process cancels a circulating hydrogen compressor, has a simple process flow, and can be applied to the production of a lubricant base oil by the hydroisomerization of a lubricant raw material or the production of a low freezing point diesel by the hydroisomerization of and the reduction in the freezing point of a diesel raw material.

  • Patent number: 10681452
    Abstract: Methods, systems, and devices for signal processing are described. Generally, as provided for by the described techniques, a wearable device may receive an input audio signal (e.g., including both an external signal and a self-voice signal). The wearable device may detect the self-voice signal in the input audio signal based on a self-voice activity detection (SVAD) procedure, and may implement the described techniques based thereon. The wearable device may perform beamforming operations or other separation procedures to isolate the external signal and the self-voice signal from the input audio signal. The wearable device may apply a first filter to the external signal, and a second filter to the self-voice signal. The wearable device may then mix the filtered signals, and generate an output signal that sounds natural to the user.

  • Publication number: 20200178014
    Abstract: Methods, systems, and devices for head-related transfer function generation are described. A device may receive a digital representation of a first audio signal associated with a location relative to a subject, and select from a database a first reference head-related transfer function measurement pair corresponding to the location of the first audio signal. The device may then obtain a second head-related transfer function measurement pair by performing a style transfer operation on the selected reference head-related transfer function measurement pair based on a set of head-related transfer function measurement pairs specific to the subject. As a result, the device may output a second audio signal based on the digital representation of the first audio signal and the second head-related transfer function measurement pair.

  • Publication number: 20190335345
    Abstract: Various embodiments disclosed herein provide for a tower outage impact predictor that can determine the service impact on an end user during a cellular tower outage. Radio signal profiling divides an area into grids, and then constructs a radio signal profile for each grid based on user equipment (UE) measurement data for each grid. The number of UEs in each grid is then determined, and then the number of UEs that lose service for a simulated cellular tower outage is determined. Based on the impact analysis, a more resilient backhaul network can be implemented by determining backhaul rehoming changes that optimally home cellular towers to various backhaul network devices.

  • Patent number: 8824461
    Abstract: Method and apparatus for providing a control plane across multiple optical network domains is described. In one example, topology and resource discovery is employed in a transport network having a plurality of control domains. Topology information for each of the control domains is summarized to produce summarized topology information. The summarized topology information for each of the control domains is exchanged among the control domains. At each of the control domains, the summarized topology information of each of the control domains is combined to produce combined topology information. The combined topology information is passed among network elements within each of the control domains using an intra-domain routing protocol.
