  • Patent number: 12240069
    Abstract: The present disclosure provides a multifunctional climbing operation platform and an operation method thereof. The multifunctional climbing operation platform includes a main machine, clamping devices, a bolt retightening device, and an auxiliary sleeve replacement box, wherein the clamping devices each include: a fixed seat; and a pair of claw bars swingably arranged on the fixed seat and each including a rear bar body and a front bar body hinged together, wherein when the pair of claw bars are opened, an inner angle between the rear bar body and the front bar body is greater than 180°, the main machine and the clamping devices can climb along an object to be climbed, the bolt retightening device can replace different sleeves from the auxiliary sleeve replacement box, and can screw a bolt on the object. The present disclosure has the advantages of a large avoidance range and diverse functions.

  • Patent number: 10708170
    Abstract: A request for a chunk of data is received from an application executing on a remote device. The chunk of data is split into a plurality of packets including a first packet and a second packet. A first sub-flow is selected to transport the first packet to the remote device and a second sub-flow is selected to transport the second packet. The first sub-flow is decoupled from the second sub-flow. A first stop time is selected for the first sub-flow and a second stop time is selected for the second sub-flow. The first stop time determines when the first sub-flow will complete at the remote device and the second stop time determines when the second sub-flow will complete at the remote device. The first stop time and the second stop time are selected so that the first sub-flow and the second sub-flow will complete simultaneously at the remote device.

  • Patent number: 10339456
    Abstract: A VoLTE diagnostic engine may receive VoLTE call records of VoLTE calls that are carried by a wireless carrier network for multiple user devices. The VoLTE call records may include performance indicators and call features for the voice calls. Each call feature of a VoLTE call may represent a circumstance under which the VoLTE call is established and ended. The VoLTE diagnostic engine may apply a decision tree to the VoLTE call records to identify critical features of one or more call conditions that lead to Quality of Experience (QoE) problems for the VoLTE calls captured in the VoLTE call records. Each call condition may include a subset of the call features. Further, the VoLTE diagnostic engine may apply a classifier on the critical features to determine a root cause of a QoE problem for at least one call conditions.
