  • Publication number: 20200086879
    Abstract: Systems and techniques for scene classification and prediction is provided herein. A first series of image frames of an environment from a moving vehicle may be captured. Traffic participants within the environment may be identified and masked based on a first convolutional neural network (CNN). Temporal classification may be performed to generate a series of image frames associated with temporal predictions based on a scene classification model based on CNNs and a long short-term memory (LSTM) network. Additionally, scene classification may occur based on global average pooling. Feature vectors may be generated based on different series of image frames and a fusion feature vector may be obtained by performing data fusion based on a first feature vector, a second feature vector, a third feature vector, etc. In this way, a behavior predictor may generate a predicted driver behavior based on the fusion feature.

  • Patent number: 10360251
    Abstract: A method and system for grouping and compressing system logs are described herein. A generation module residing and executing on a computer system may be configured to generate system logs containing system data important for support purposes describing the computer system, and system log metadata for describing the system logs. A grouping module residing and executing on a computer system may be configured to group system logs based on the system log metadata. Each group of system logs may comprise two or more system logs having the same or similar system log metadata. A data container is produced for each group of system logs and the data container is compressed. System logs having the same or similar system log metadata are more likely to have similar data, thus resulting in a higher degree of compression when grouped and compressed together.

  • Publication number: 20180363410
    Abstract: Downhole plugs having single anchoring mechanisms and methods thereof are disclosed. The plug comprises of inner mandrel with proximal portion and distal portion, outer assembly and one or more retaining members. The outer assembly comprises of support element, elastomeric element for sealing the gap between the plug and casing, anchoring mechanism at the distal portion for anchoring the plug to the casing and nose element. The elastomeric element is retained in a compressed state at the downhole end by the anchoring mechanism and at the up hole end by the retaining members. In some embodiments, the retaining members are snap rings that are pushed down from step portions at the proximal portion when the plug is mobilized to a set position thereby retaining the elastomeric element. In some embodiments, the retaining members are ratcheted open rings that ratchet over the proximal portion thus retaining the elastomeric element.

  • Patent number: 9949142
    Abstract: Small cell provisioning and validation may be performed, for small cells, in a small cell cluster, based on wireless cellular network connections (i.e., without requiring the use of a backhaul connection). In some implementations, the small cells may communicate with one another using direct Device-to-Device (D2D) communications. The D2D communications may be used to further enhance the network connectivity (i.e., to the cellular network and the OAM server) and to transmit test traffic during performance of the validation functions.
