  • Publication number: 20210185616
    Abstract: Systems, methods, devices, computer readable media, and other various embodiments are described for location management processes in wearable electronic devices. Performance of such devices is improved with reduced time to first fix of location operations in conjunction with low-power operations. In one embodiment, low-power circuitry manages high-speed circuitry and location circuitry to provide location assistance data from the high-speed circuitry to the low-power circuitry automatically on initiation of location fix operations as the high-speed circuitry and location circuitry are booted from low-power states. In some embodiments, the high-speed circuitry is returned to a low-power state prior to completion of a location fix and after capture of content associated with initiation of the location fix. In some embodiments, high-speed circuitry is booted after completion of a location fix to update location data associated with content.

  • Patent number: 11026052
    Abstract: Systems, methods, devices, computer readable media, and other various embodiments are described for location management processes in wearable electronic devices. One embodiment involves pairing a client device with a wearable device, capturing a first client location fix at a first time using the first application and location circuitry of the client device. The client device then receives content from the wearable device, where the content is associated with a content capture time and location state data. The client device then updates a location based on the available data to reconcile the different sets of location data. In some embodiments, additional sensor data, such as data from an accelerometer, is used is used to determine which location data is more accurate for certain content.

  • Publication number: 20210160263
    Abstract: Systems and methods for causation analysis of network anomalies in a network include detecting an alarm condition at a network device, the alarm condition pertaining to an anomaly or increase in a traffic condition such as packet loss. A dominant key is identified in each of one or more key types which contributed to the alarm condition, the key types including dimensions of traffic flow. Two or more dominant keys of two or more key types are aggregated and clustered to determine a combination of dominant keys which contributed to the alarm condition. A dominant traffic flow comprising the combination of dominant keys which contributed to the alarm condition is identified based on the aggregation and clustering. Malware or security threats can be identified from detecting a dominant source IP address or host which contributed to a predominant number of packet drops or retransmissions at ports of the network.

  • Publication number: 20210092422
    Abstract: A method of decoding a bistream by an electronic device is provided. A block unit is determined from an image frame according to the bitstream. A line index determined in the bitstream is compared with a first predefined value to determine whether a mode flag is included in the bitstream. A mode index is determined for directly selecting a prediction mode of the block unit from a most probable mode (MPM) list of the block unit when the mode flag is not included in the bitstream. The mode flag is compared to a second predefined value when the mode flag is included in the bitstream to determine whether the prediction mode is selected from the MPM list. One of a plurality of reference lines is selected based on the line index. The block unit is reconstructed based on the selected reference line and the prediction mode.
