  • Patent number: 10670771
    Abstract: A weather forecasting system may receive satellite image samples and identify an updraft and components of the updraft within a cloud. These satellite image samples are collected over time (e.g., at 30 second to 1 minute time intervals). The system may identify an area of rotation and/or divergence at cloud top in a cumulus cloud or mature convective storm over time by comparing the samples and determine a parameter indicative of the updraft based on the area of rotation and divergence. The system may estimate aspects of the environment related to storm development and predict the occurrence of a weather event in the future based on the parameter and generate an output indicative of the occurrence.

  • Patent number: 10630636
    Abstract: Systems and methods are provided to implement an anti-censorship framework that includes moving target defense systems and methods. The framework can be implemented at a web server hosting content that is intended to be accessed by one or more users. The web server can utilize dynamically changing IP addresses to avoid filtering and blocking (and also from being attacked) by censors. Users can be assigned to random groups and provided with a dynamic IP address of the web server that is unique for that group. After some time interval (called a shuffling interval), the web server can generate new sets of dynamic IP addresses and re-randomize the user groups and update the users with new IP addresses for the web server.

  • Patent number: 10613252
    Abstract: A weather forecasting system has a data processing system that receives weather data from one or more sources and processes such data in conjunction with a weather forecasting algorithm in order to forecast weather for one or more geographic regions. In this regard, the weather data is input into a machine learning algorithm, which applies learned weights and relationships to the inputs in order to calculate at least one score indicating a probability that precipitation or other weather event will occur in the future within a certain time period (e.g., within the next 1 hour or some other unit of time) in one or more geographic regions. For each such geographic region, the weather forecasting logic may also predict the extent to which rain or other precipitation, lightning, or other weather event will occur during the time period.

  • Patent number: 10554683
    Abstract: Systems and methods are provided to implement moving target defense techniques for transportation systems. The moving target defense techniques can randomly change the IP addresses of the nodes associated with both the vehicles and the corresponding control centers. The nodes for the vehicles and the control centers can be “mobile” nodes that use a “care-of” IP address for communications. The care-of address used by the nodes can be updated through a binding update process. During the binding update process, the one node sends the binding update notice (with a new care-of address) to the care-of address of the other node while maintaining its prior care-of address. The node that receives the binding update notice can send a binding acknowledgement back to the node that sent the binding update. Once the binding acknowledgement is received, the prior care-of address can be removed by the node that sent the binding update.

  • Patent number: 10505269
    Abstract: A magnetic antenna structure has a substrate (e.g., a flexible printed circuit board (PCB) carrier), a magneto-dielectric (MD) layer, and an antenna radiator. The MD layer increases electromagnetic (EM) energy radiation by lowering the EM energy concentrated on the antenna substrate. The resonant frequency and antenna gain of the magnetic antenna structure are generally lower and higher, respectively, relative to dielectric antennas of comparable size. Thus, the magnetic antenna structure provides better miniaturization and high performance with good conformability.
