Patent number: 11769385Abstract: A system and computer software mechanism is disclosed that can automatically detect smoking conditions for industrial flares. In an online mode, the software mechanism can analyze live video images to identify smoking conditions and generate a “Smoke Level” value to represent the seriousness of the smoking events. In an off-line mode, the software mechanism can load saved video files and analyze video images to identify smoking conditions and generate a “Smoke Level” value to represent the seriousness of the smoking events. In the online mode, the Smoke Level data can be sent to the plant distributed control system (DCS) or other control devices so alarms can be generated and automatic or manual control actions can be taken quickly to stop the flare from smoking. In both online and off-line modes, Smoke Level data can also be saved in historical files for reporting and smoke event tracking purposes.Type: GrantFiled: September 30, 2022Date of Patent: September 26, 2023Assignee: General Cybernation Group, Inc.Inventors: George Shu-Xing Cheng, Andrew J. Chow, Manuel Martinez

Patent number: 11462089Abstract: A method and system is disclosed that can automatically detect smoking conditions for industrial flares. It can analyze live or historical video images to identify smoking conditions and generate a “Smoke Level” value in the range of 0 to 10 to represent the seriousness of the smoking events. The Smoke Level data can be sent to the plant distributed control system (DCS) or other control devices so alarms can be generated and automatic or manual control actions can be taken to stop the flare from smoking quickly. The Smoke Level data can also be saved in historical files for reporting and smoke event tracking purposes. Using the described method and system, industrial plants can comply with EPA regulations at all times, improve flare control and monitoring, be better prepared for EPA reporting and auditing, and save energy and manpower.Type: GrantFiled: February 24, 2021Date of Patent: October 4, 2022Assignee: General Cybernation Group, Inc.Inventors: George Shu-Xing Cheng, Andrew J.

Publication number: 20180175623Abstract: A method and apparatus is disclosed that can intelligently invert DC power from single or multiple DC sources to single-phase, split-phase, or three-phase AC power, supply the AC power to the electric power grid when the grid is on, or supply AC power to electric devices or loads when the grid is down. A Smart and Grid-Flexible Power Inverter, or On/Off-Grid Power Inverter, is disclosed that can work in either the on-grid or off-grid mode, and switch back and forth between the two modes manually or automatically depending on the power grid conditions. The system provides a simple and cost-effective solution for areas where the power grid has frequent outages or long downtimes.Type: ApplicationFiled: February 15, 2018Publication date: June 21, 2018Inventors: George Shu-Xing Cheng, Steven L.

Patent number: 9871379Abstract: A method and apparatus is disclosed relating to smart microgrids supported by dual-output off-grid power inverters with DC source flexibility that can (1) intelligently and selectively pull power from one or multiple DC sources including solar panels, wind generators, and batteries based on certain criteria; (2) invert DC power to AC power; (3) supply the AC power to two off-grid circuits individually to power various types of AC loads that require different AC voltages, power quality, and power levels; (4) supply DC power through one or multiple DC output ports to power DC loads; and (5) charge batteries. Two or multiple dual-output off-grid power inverters can daisy-chain to form a group to support a larger microgrid which is ideal for off-grid AC Level 1 and Level 2 EV charging.Type: GrantFiled: February 18, 2015Date of Patent: January 16, 2018Assignee: CYBOENERGY, INC.Inventors: George Shu-Xing Cheng, Steven L.

Patent number: 9331489Abstract: A method and apparatus is disclosed for maximizing power production for solar power systems when there is low sunlight during sunrise, sunset, clouding, partial shading, and other low irradiance conditions. A multiple-channel solar power Mini-Inverter can work in the low power mode when there is low sunlight, take power from one solar panel to supply DC power to its internal electronic circuits, and also invert the DC power from the remaining connected solar panels to single-phase or three-phase AC power feeding to the electrical grid or powering AC loads. This invention can significantly reduce the required startup and shutdown irradiance and DC power for the solar power inverter, avoid undesirable shutdowns due to partial shading, and allow the inverter to run in power generation mode for a few more hours each day.Type: GrantFiled: March 7, 2013Date of Patent: May 3, 2016Assignee: CyboEnergy, Inc.Inventors: George Shu-Xing Cheng, Steven L.
