Filters may be utilized by an edge electronic device to filter elements of an input data stream so that only a subset of the elements are used as inputs to a machine learning model run by the electronic device, enabling successful operation despite the input data stream potentially being generated at a higher rate than a rate in which the ML model can be executed. The filter can be a differential-type filter that generates difference representations between consecutive elements of the data stream to determine which elements are to be passed on for the ML model, a “smart” filter such as a neural network trained using outputs from the ML model allowing the filter to “learn” which elements are the most likely to be of value to be passed on, or a combination of both. |

Learning automaton and low-pass filter having a pass band that widens over time
A learning automaton can be trained to merge data from input data streams, optionally with different data rates, into a single output data stream.

Universal wall boundary condition treatment for k-omega turbulence models
Disclosed are techniques for simulating a physical process and for determining boundary conditions for a specific energy dissipation rate of a k-Omega turbulence fluid flow model of a fluid flow, by computing from a cell center distance and fluid flow variables a value of the specific energy dissipation rate for a turbulent flow that is valid for a viscous layer, buffer layer, and logarithmic region of a boundary defined in the simulation space. The value is determined by applying a buffer layer correction factor as a first boundary condition for the energy dissipation rate and by applying a viscous sublayer correction factor as a second boundary condition for the energy dissipation rate. |

Machine learning based systems and methods for real time, model based diagnosis
The disclosure following relates generally to complex simulations, and fault diagnosis. In some embodiments, a component that is causing a delayed simulation time of a system is determined. A component of reduced complexity is designed, and the component of reduced complexity is used to replace the original component in the system. Fault diagnosis may then be conducted using the updated system with the reduced complexity component, thus decreasing the time taken to diagnose the fault. |

Subsampling method for converting 3D scan data of an object for marine, civil, and architectural works into smaller densities for processing without CAD processing
The point cloud scan image data first is structured with a x-y-z coordinate system, then split into smaller Cluster Bounds (CB) volumes and a CB x-y-z is imposed on the CB centroid. The Euclidean x-y-z distance (ED) is calculated for each data point. Only points within Radial Distance (RD cylinder) are retained/processed. Data points within RD are weighted; points closer to centroid having higher weights. Each data point has Weighted Value WV (square of the inverse of the x-y-z distance). Each x, y, z has Weighted Average (WAV) per axes. WAV is sum of each original point coordinate times WV, divided by sum all WVs. Resultant is one subsampled point per axis. One WAV per CB is selected based upon axis nearly orthogonal to x, y, z WAV points. All CBs subsampled in parallel. Subsampled output comma separated coordinate file for CAD program. |

Protection against unintended content change in DRAM during standby mode
Systems, methods, and apparatus related to protecting data stored in volatile memory of a computing system during a standby mode. In one approach, a first signature is generated for data stored in volatile memory. In some cases, the stored data may include sensor data obtained from one or more sensors of a vehicle, mobile device or other electronic device. The first signature is stored in a non-volatile memory device, and then the computing system enters the standby mode. Subsequently, after exiting the standby mode, a second signature is generated for the data stored in the volatile memory. The first signature is read from the non-volatile memory device and compared to the second signature. A signature mismatch indicates that an unintended change has occurred in the stored data during the standby mode. One or more remedial actions are performed by the computing system in response to this signature mismatch. |

Data processing systems and methods for automatically protecting sensitive data within privacy management systems
In particular embodiments, a sensitive data management system is configured to remove sensitive data after a period of non-use. Credentials used to access remote systems and/or third-party systems are stored with metadata that is updated with each use of the credentials. After a period of non-use, determined based on credential metadata, the credentials are deleted. Personal data retrieved to process a consumer request is stored with metadata that is updated with each use of the personal data. After a period of non-use, determined based on personal data metadata, the personal data is deleted. The personal data is also deleted if the system determines that the process or system that caused the personal data to be retrieved is no longer in use. An encrypted version of personal data may be stored for later use in verifying proper consumer request fulfillment. |

Systems and methods for secure cloud-based medical image upload and processing
Presented herein are systems and methods that facilitate user review and uploading of files comprising medical images and associated metadata from a local computing device to a network-based image analysis and/or decision support platform. The systems and methods described herein allow image upload to be performed in a secure fashion that prevents the network-based platform from accessing sensitive data as it is prepared for upload. Prior to file upload, sensitive data elements are flagged and their values removed and/or masked. Notably, the approaches described herein provide intuitive graphical user interface (GUI) tools that allow a user, such as a medical practitioner or researcher, to review not only the images and metadata in the files that they plan to upload, but also to review and control the process by which sensitive data elements are removed and/masked, thereby confirming that all files are free of sensitive information prior to upload. |

System and method for decentralized data storage
A system and method for the decentralized storage of data is provided that pre-processes data files to generate multiple subsets of encrypted data that includes randomly selected portions of data from different data files. The subsets of encrypted data are then transmitted to multiple remote servers that are randomly chosen for each subset of encrypted data. The local encryption key that was used to encrypt the data is required to reconstruct the data file. The system and method is particularly suited for the decentralized storage of medical data. |
