Abstract: An attestation framework to support attestation and anomaly detection in an electric grid. The attestation framework provides systems and methods that use distributed ledger technology (DLT) and implement DLT-based methods for verifying device and data trustworthiness on the electric grid. The framework attests to system changes and anomaly detection to flag specific events such as natural and cyber-induced grid events categorization, electrical faults in meters and relays and cyber events, e.g., based on statistical and baseline threshold values. The attestation framework can support the detection of system changes by itself, and in combination with an anomaly detection framework, has a lower system resource requirement and is more likely to catch system changes. An anomaly detection module can trigger attestation checks and uses the DLT for device and configuration verification purposes. The attestation framework can be deployed at substations or other environments, such as DERs or a microgrid.

Abstract: A synesthesia-based encryption system and method (referred to as a system) includes a camera that captures an image and a transceiver communicatively coupled to the camera and a video-only network. The system includes a sensor that monitors a location and generates a sensor message. The sensor message include information that represents a state, a measurement, and/or a detection at that location. The system's processor maps colors to characters from the sensor message to generate a replacement image. In some systems, the sensor is encrypted first. The processor integrates the replacement image within the original image or some or all of the video frames captured by the camera to form a combined image(s) and causes a transceiver to transmit the combined image(s) across the video-only network to a destination.

Abstract: A phase to ground fault apparent (PGFA) admittance system and method with phase/ground boundaries for detecting electrical power line faults. The PGFA admittance method with phase/ground boundaries is based on measuring the A, B and C phase admittance magnitudes for faulted and non-faulted phases, resulting in greater than zero and near zero, respectively, and using the phase/ground boundaries to distinguish between the LL and LLG electrical faults. The PGFA admittance method with phase/ground boundaries is based on a pre-setting of values by using the zero, positive and negative sequences of power line sections, to determine phase and ground boundaries. The PGFA admittance algorithm with phase/ground boundaries was built with MATLAB/Simulink software and tested and evaluated with a confusion matrix. The measured and predicted values matched in more than 90% of the tests, and the PGFA admittance method presented an accuracy of 94.3% and a precision of 100%.

Abstract: A method for processing a food product involves transporting the food product through a plurality of stations including a loading station, a pasteurization station, and a closing station. The surface of the food product is pasteurized by convectively transferring heat from the pasteurizing medium to the surface of the food product at a rate such that the surface heat transfer coefficient becomes sufficiently higher than the food product conductance coefficient that the surface temperature of the food product is substantially instantaneously elevated above temperatures which are instantly lethal to microbes which may be present. Preferably, steam is condensed on the food product surface in dropwise condensation, and the onset of film condensation is retarded by removing condensate film from such surface.

Abstract: The present invention has a shaft with a chisel and a ladle at opposed ends. Two stops are welded to the shaft, and a slide assembly is located between the stops. A first handle is between the chisel and the first stop, and a second handle is between the ladle and the second stop. The slide assembly strikes the first stop to make the chisel break through the ice. The ladle is used to scoop out any pieces of ice that are in the hole. A rubber material is on the slide assembly and on the second handle to prevent the user's gloves from freezing thereon. The chisel can be driven into the frozen surface, but not through the frozen surface, to form an anchor. Removal of the anchor is accomplished by striking the slide assembly against the second stop.

Abstract: In a web packaging machine (10) and method packaging a food product (P) between upper and lower webs (14 and 25), wherein the lower web (14) is transported through a series of stations which form the lower web (14) into a component of a package at a forming station (18), and receive the food product (P) at a loading station (20), and close the package with the upper web (25) at a closing station (26), a pasteurization station (300) is provided between the loading station (20) and the closing station (26) and pasteurizing the food product (P).
