Patent number: 11388178Abstract: Extensive deployment of interoperable distributed energy resources (DER) on power systems is increasing the power system cybersecurity attack surface. National and jurisdictional interconnection standards require DER to include a range of autonomous and commanded grid-support functions which can drastically influence power quality, voltage, and the generation-load balance. Investigations of the impact to the power system in scenarios where communications and operations of DER are controlled by an adversary show that each grid-support function exposes the power system to distinct types and magnitudes of risk. The invention provides methods for minimizing the risks to distribution and transmission systems using an engineered control system which detects and mitigates unsafe control commands.Type: GrantFiled: November 20, 2019Date of Patent: July 12, 2022Assignee: National Technology & Engineering Solutions of Sandia, LLCInventor: Jay Tillay Johnson

Patent number: 11387802Abstract: A hybrid ferroelectric/non-ferroelectric piezoelectric microresonator is disclosed. The hybrid microresonator uses a ferroelectric layer as the actuator as ferroelectric materials typically have higher actuation coefficients than non-ferroelectric piezoelectric materials. The hybrid microresonator uses a non-ferroelectric piezoelectric layer as the sensor layer as non-ferroelectric piezoelectric materials typically have higher sensing coefficients than ferroelectric materials. This hybrid microresonator design allows the independent optimization of actuator and sensor materials. This hybrid microresonator design may be used for bulk acoustic wave contour mode resonators, bulk acoustic wave solidly mounted resonators, free-standing bulk acoustic resonators, and piezoelectric transformers.Type: GrantFiled: October 21, 2019Date of Patent: July 12, 2022Assignees: National Technology & Engineering Solutions of Sandia, LLC, The United States of America as Represented by the Secretary of the ArmyInventors: Benjamin Griffin, Christopher Nordquist, Ronald G.

Patent number: 11379991Abstract: A method for digital image segmentation is provided. The method comprises training a neural network for image segmentation with a labeled training dataset from a first domain, wherein a subset of nodes in the neural net are dropped out during training. The neural network receives image data from a second, different domain. A vector of N values that sum to 1 is calculated for each image element, wherein each value represents an image segmentation class. A label is assigned to each image element according to the class with the highest value in the vector. Multiple inferences are performed with active dropout layers for each image element, and an uncertainty value is generated for each image element. The label of any image element with an uncertainty value above a predefined threshold is replaced with a new label corresponding to the class with the next highest value.Type: GrantFiled: May 29, 2020Date of Patent: July 5, 2022Assignee: National Technology & Engineering Solutions of Sandia, LLCInventors: Carianne Martinez, Kevin Matthew Potter, Emily Donahue, Matthew David Smith, Charles J.

Patent number: 11378576Abstract: Viruses and other bioagents are of high medical and biodefense concern and their detection at concentrations well below the threshold necessary to cause health hazards continues to be a challenge with respect to sensitivity, specificity, and selectivity. Ideally, assays for accurate and real time detection of viral agents and other bioagents would not necessitate any pre-processing of the analyte, which would make them applicable for example to bodily fluids (blood, sputum) and man-made as well as naturally occurring bodies of water (pools, rivers). We describe herein a robust biosensor that combines the sensitivity of surface acoustic waves (SAW) generated at a frequency of 325 MHz with the specificity provided by antibodies and other ligands for the detection of viral agents.Type: GrantFiled: February 15, 2019Date of Patent: July 5, 2022Assignees: UNM Rainforest Innovations, National Technology & Engineering Solutions of Sandia, LLCInventors: Richard S.
