  • Patent number: 11604442
    Abstract: System and method for improving operation of an industrial automation system, which includes a control system that controls operation of an industrial automation process. The control system includes a feature extraction block that determines extracted features by transforming process data determined during operation of an industrial automation process based at least in part on feature extraction parameters; a feature selection block that determines selected features by selecting a subset of the extracted features based at least in part on feature selection parameters, in which the selected features are expected to be representative of the operation of the industrial automation process; and a clustering block that determines a first expected operational state of the industrial automation system by mapping the selected features into a feature space based at least in part on feature selection parameters.

  • Patent number: 10631182
    Abstract: First and second pluralities of packets transmitted between UE and the USN over a first interface and a second interface are continuously captured. The first, second and third pluralities contains temporary and permanent identifying information and ciphering key information. A fourth plurality of packets transmitted between the USN and a HSS over a fourth interface is captured. The temporary, permanent identifying information and the ciphering key information are correlated to determine mappings stored in a data repository. A fifth plurality transmitted over a fifth interface is continuously captured. Permanent identifying information corresponding to the temporary identifying information retrieved from the unciphered packets of the fifth plurality is retrieved from the data repository based on the stored mappings. NAS deciphering key information corresponding to the retrieved permanent identifying information is retrieved.
