Abstract: A computing system may include a fail-safe learning engine configured to access camera data captured by multiple cameras positioned within an environment during a learning phase, generate training data based on the camera data captured by the multiple cameras, and construct a human detection model using the training data. The computing system may also include a fail-safe trigger engine configured to access camera data captured by the multiple cameras positioned within the environment during an active phase, and the camera data captured during the active phase may include a target object. The fail-trigger engine may further be configured to provide, as an input to the human detection model, the camera data that includes the target object and execute a fail-safe action in the environment responsive to the determination, provided by the human detection model, indicating that the target object is a human.

Abstract: A method for providing cybersecurity to an industrial system having multiple components includes monitoring communications across the components of the system and detecting a deviation in an expected communication state in a first component. Upon detection of a deviation, communication states of at least one other component in the system is observed. If a deviation is also detected in the other component, then the deviation is deemed to be unauthorized. If no other deviations are detected in other components, the original deviation is deemed to be benign. Detecting a deviation includes comparing an expected communication state based on a baseline to the current communication state, the communication state may be based on a communication's content or a pattern of communication actions.

Abstract: Technical solutions are described for performing sensitivity analysis for engineering systems in spatial-temporal domain. An example method includes receiving a set of process parameters and retrieving a multidimensional dataset containing historical values of the process parameters and corresponding output values. The method further includes selecting a sampling algorithm to divide the multidimensional dataset into multiple subspaces, and selecting multiple samples (xi), one sample from each subspace. The method further includes perturbing the samples, computing a first effect (EEi) on an output value (y), and computing a second effect (SEEii) of perturbing a pair of samples (xi and xj) on the output value. The method further includes computing a sensitivity coefficient of the process parameters on the output value using the second effect for xi and xj, the first effect for xi, and the first effect for xj. An automatic visualization scheme for the global sensitivity results is also provided.

Abstract: Method and apparatus to provide protocol translation and selectable data exchange in a client/server system are provided. A tag list is extracted from a legacy client device 116 connected to a legacy server 114 using a protocol corresponding to the legacy server. A configuration manager device 120 is used to configure the extracted tag list to obtain a selected tag list excerpt of the extracted tag list. The configuring device is arranged to map the selected tag list excerpt to a configuration adapted for a respective 112 server, and to define contextualization. Server 112 provides industrial automation services using a next-generation protocol, e.g., OPC UA or MTConnect. A tag list is generated to configure server 112. A stream of data points of the selected tag list excerpt of the tag list extracted from the legacy client device is transferred to one or more client devices 124 connected to server 112.
