Abstract: A verification platform may include a data connection to receive a stream of industrial asset data, including a subset of the industrial asset data, from industrial asset sensors. The verification platform may store the subset of industrial asset data into a data store, the subset of industrial asset data being marked as invalid, and record a hash value associated with a compressed representation of the subset of industrial asset data combined with metadata in a secure, distributed ledger (e.g., associated with blockchain technology). The verification platform may then receive a transaction identifier from the secure, distributed ledger and mark the subset of industrial asset data in the data store as being valid after using the transaction identifier to verify that the recorded hash value matches a hash value of an independently created version of the compressed representation of the subset of industrial asset data combined with metadata.

Abstract: Techniques for responding to content requests that originate from remote computing devices are provided. In one technique, a content request that includes a viewer identifier of a user that requested web content and a contextual entity identifier of an entity that is referenced in the web content is received. In response to receiving the content request, based on the viewer identifier, first profile data about a viewer associated with the viewer identifier is retrieved. Also, based on the contextual entity identifier, second profile data about the entity is retrieved. Based on the first profile data and the second profile data, a content delivery campaign is identified. Particular content to deliver is determined based on the content delivery campaign. The particular content is sent to a computing device that initiated the content request.

Abstract: According to some embodiments, a threat detection computer platform may receive a plurality of real-time monitoring node signal values over time that represent a current operation of the industrial asset. For each stream of monitoring node signal values, the platform may generate a current monitoring node feature vector. The feature vector may also be estimated using a dynamic model output with that monitoring node signal values. The platform may then compare the feature vector with a corresponding decision boundary for that monitoring node, the decision boundary separating a normal state from an abnormal state for that monitoring node. The platform may detect that a particular monitoring node has passed the corresponding decision boundary and classify that particular monitoring node as being under attack. The platform may then automatically determine if the attack on that particular monitoring node is an independent attack or a dependent attack.

Abstract: According to some embodiments, streams of monitoring node signal values may be received over time that represent a current operation of an industrial asset control system. A current operating mode of the industrial asset control system may be received and used to determine a current operating mode group from a set of potential operating mode groups. For each stream of monitoring node signal values, a current monitoring node feature vector may be determined. Based on the current operating mode group, an appropriate decision boundary may be selected for each monitoring node, the appropriate decision boundary separating a normal state from an abnormal state for that monitoring node in the current operating mode. Each generated current monitoring node feature vector may be compared with the selected corresponding appropriate decision boundary, and a threat alert signal may be automatically transmitted based on results of said comparisons.

Abstract: A wrapper interface is provided. The wrapper interface maps transaction and monitoring operations of a Point-Of-Sale (POS) transaction interface within an operator-facing interface.

Abstract: Heterogeneous monitoring nodes may each generate a series of monitoring node values over time associated with operation of an industrial asset. An offline abnormal state detection model creation computer may receive the series of monitoring node values and perform a feature extraction process using a multi-modal, multi-disciplinary framework to generate an initial set of feature vectors. The model creation computer may then perform feature dimensionality reduction to generate a selected feature vector subset. The model creation computer may derive digital models through a data-driven machine learning modeling method, based on input/output variables identified by domain experts or by learning from the data. The system may then automatically generate domain level features based on a difference between sensor measurements and digital model output.

Resting zones may also be provided. The batteries can be connected in series or in parallel and can be individually removed and replaced by an exchanger.

Abstract: According to some embodiments, a validation platform computer may interpret at least one received data packet to identify a control command for a controller of an industrial asset control system. The at least data packet being might be received, for example, from a network associated with a current operation of the industrial asset control system. The control command may then be introduced into an industrial asset simulation executing in parallel with the industrial asset control system. A simulated result of the control command from the industrial asset simulation may be validated, and, upon validation of the simulated result, it may be arranged for the control command to be provided to the controller of the industrial asset control system. Additionally, in some embodiments failed validation of a simulated result will prompt a threat-alert signal as well as prevent the command (e.g., data packet) from continuing to the controller.

Abstract: A method of bonding a diamond wafer to a carrier substrate. The diamond wafer is placed on the carrier substrate, the diamond wafer having a diameter of at least 50 mm. A voltage is applied to the carrier substrate which induces an electrostatic force which bonds the diamond wafer to the carrier substrate. The voltage applied to the carrier substrate is removed, leaving the diamond wafer bonded to the carrier substrate via residual electrostatic force. A mounted diamond wafer comprises a diamond wafer having a diameter of at least 50 mm and a carrier substrate, wherein the diamond wafer is bonded to the carrier substrate via a residual electrostatic force.

Abstract: This disclosure describes techniques for providing users of services provided by network-based service platforms with additional control for approving patches that are to be deployed to computing resources that support their services. In some examples, the techniques include generating and using a “snapshot,” or list, of patches that are preliminarily approved for deployment. Prior to deploying the patches to the computing resources, users are provided with access to the snapshot and are able to modify the snapshot. For example, users can modify the snapshot by adding patches, removing patches, specifying a sequence in which the patches are to be deployed, and so forth. The snapshot of patches may be “frozen” for a period of time, meaning that patches that during the period of time, only patches in the snapshot are deployed, and patches that are not included in the snapshot are not permitted to be deployed to computing resources.
