Abstract: A redundant and diverse secondary control system mirrors a primary control system but has some fundamental structural difference as compared to the primary control system to prevent a spread of a security breach from the primary control system to the secondary control system. The secondary control system may operate on different hardware built on different software written with different programming language as compared to the primary control system while performing the same function as that of the primary system. By hardware coding the algorithm to produce actuation signals, software based viruses and worms cannot interfere with the secondary control system's operation. A monitor device receives actuation signals from both the primary and secondary controls signals to determine whether an error occurred and to provide correct actuation signals to the controlled system.

Information is displayed at the display unit based upon the context. The context is transmitted from the first electronic device to a second electronic device, and from the first electronic device and to a third electronic device. A first consistency of information is maintained between the first electronic device and a second electronic device based at least upon the context, and a second consistency is maintained between the first electronic device and a third electronic device based at least upon the context. The first consistency is greater than the second consistency.
Abstract: A majorize-minimize (MM) mathematical principle is applied to least squares regularization estimation problems to effect efficient processing of image data sets to provide good quality images. In a ground penetrating radar application, these approaches can reduce processing time and memory use by accounting for a symmetric nature of a given radar pulse, accounting for similar discrete time delays between transmission of a given radar pulse and reception of reflections from the given radar pulse, and accounting for a short duration of the given radar pulse.
Abstract: The mathematical majorize-minimize principle is applied in various ways to process the image data to provide a more reliable image from the backscatter data using a reduced amount of memory and processing resources. A processing device processes the data set by creating an estimated image value for each voxel in the image by iteratively deriving the estimated image value through application of a majorize-minimize principle to solve a maximum a posteriori (MAP) estimation problem associated with a mathematical model of image data from the data. A prior probability density function for the unknown reflection coefficients is used to apply an assumption that a majority of the reflection coefficients are small. The described prior probability density functions promote sparse solutions automatically estimated from the observed data.

Abstract: A distance from a measurement point to a fault in a three-phase circuit is determined. The measurement point is located at an output of a power sub-station and the three phase circuit has a loop circuit having an associated net fault line current and a ground current. A derivative of the net fault line current of the loop circuit as measured from the measurement point is calculated. An uncompensated distance to the sub-cycle fault using at least the derivative of the net fault current is determined, and configured, to compensate for the ground current of the loop circuit. The compensation is applied to the uncompensated distance to produce a compensated distance to the sub-cycle fault.
