Abstract: A real-time monitoring system for skid-mounted reciprocating natural gas compressors. The system not only monitors performance and makes analytical diagnostic predictions of potentially problematic valves and such, but also has alert system for real-time monitoring, troubleshooting and diagnosing of such natural gas compressors—both locally and remotely. Operators can more efficiently and effectively manage maintenance and operation of the skid-mounted compressors with the implementation of LED equipped sensors that allow operators to locally quickly identify valves and other components requiring maintenance. Additionally, operators can remotely identify and understand deviations from optimal performance with the implementation of color-coded soft gauges.

Abstract: A gas processing system comprises a compressor, an engine configured to drive the compressor, and a control system with emissions quantification capabilities. In some examples, one or more emissions lines direct leakage emissions from the compressor to the engine to be ingested as an alternate fuel source. One or more oxygen sensors generate oxygen sensor data indicating oxygen levels in an exhaust stream of the engine. The control system determines an actual air-fuel ratio of the exhaust stream based at least in part on the oxygen sensor data. The control system determines an error correction corresponding to an adjustment in the air-fuel mixture supplied to the engine to compensate for a difference between the actual air-fuel ratio and a commanded stoichiometric air-fuel ratio. The control system quantifies the leakage emissions from the compressor based at least in part on a comparison of the error correction to a baseline error correction.

Abstract: A fault-tolerant analog computing device includes a crossbar array having a number l rows and a number n columns intersecting the l rows to form l×n memory locations. The l rows of the crossbar array receive an input signal as a vector of length l. The n columns output an output signal as a vector of length n that is a dot product of the input signal and the matrix values defined in the l×n memory locations. Each memory location is programmed with a matrix value. A first set of k columns of the n columns is programmed with continuous analog target matrix values with which the input signal is to be multiplied, where k<n. A second set of m columns of the n columns is programmed with continuous analog matrix values for detecting an error in the output signal that exceeds a threshold error value, where m<n.

Abstract: Various embodiments of the present invention include methods for determining nanowire addressing schemes and include microscale/nanoscale electronic devices that incorporate the nanowire addressing schemes for reliably addressing nanowire-junctions within nanowire crossbars. The addressing schemes allow for change in the resistance state, or other physical or electronic state, of a selected nanowire-crossbar junction without changing the resistance state, or other physical or electronic state, of the remaining nanowire-crossbar junctions, and without destruction of either the selected nanowire-crossbar junction or the remaining, non-selected nanowire-crossbar junctions. Additional embodiments of the present invention include nanoscale memory arrays and other nanoscale electronic devices that incorporate the nanowire-addressing-scheme embodiments of the present invention.
