Abstract: An apparatus and methods to make a product using supersonic cold-spray deposition of brittle functional materials in fine and micro features down to 10 ?m in minimum dimension. The process may use semiconductors such as bismuth and antimony telluride formulations, and hard magnetic materials such as neodymium iron boride and strontium ferrite, and soft magnetic materials such as manganese zinc ferrite, and manganese ferrite materials. In addition, the methods and processes have been demonstrated for materials as soft as graphite and as hard as boron carbide. Micro components have been deposited in square, tapered and elongated shaped features with feature sizes as small as 10 ?m in minimum dimensions and applied to flat and highly complex shaped surfaces. This process when combined with other cold spray manufacturing processes allows the total additive manufacturing of complete electronic, magnetic and other complex devices including multiple type of brittle functional materials.

Abstract: Provided are methods and systems for cluster-based mitigation of a network attack. A method for cluster-based mitigation of a network attack may commence with detecting an unusual pattern in network data traffic associated with data sources. The method may further include extracting signature parameters associated with the network data traffic. The signature parameters may be indicative of the network attack. The method may continue with assigning importance weights to the signature parameters based on historical signature data to generate weighted signature parameters. The method may further include building a decision tree for the data sources based on the weighted signature parameters. The method may continue with creating an optimal number of clusters for the data sources based on an analysis of the decision tree. The method may further include selectively taking at least one mitigating action with regard to the data sources within the clusters.

Abstract: A touch sensor system includes touch sensors, drive-sense circuits (DSCs), memory, and a processing module. A DSC drives a first signal via a single line coupling to a touch sensor and simultaneously senses, when present, a second signal that is uniquely associated with a user. The DSC processes the first signal and/or the second signal to generate a digital signal that is representative of an electrical characteristic of the touch sensor. The processing module executes operational instructions (stored in the memory) to process the digital signal to detect interaction of the user with the touch sensor and to determine whether the interaction of the user with the touch sensor compares favorably with authorization. When not authorized, the processing module aborts execution of operation(s) associated with the interaction of the user with the touch sensor. Alternatively, when authorized, the processing module facilitates execution of the operation(s).

Abstract: A system includes a computing platform having a hardware processor and a memory storing a software code and a neural network (NN) having multiple layers including a last activation layer and a loss layer. The hardware processor executes the software code to identify different combinations of layers for testing the NN, each combination including candidate function(s) for the last activation layer and candidate function(s) for the loss layer.

The software code determines a preferred combination of layers for the NN including selected candidate functions for the last activation layer and the loss layer, based on a comparison of the performance assessments.
