摘要： A system includes a gas distribution network having sub-networks including a first sub-network, each sub-network including a pipe section having a gas safety device coupled to a gas safety valve. The gas safety device includes a pressure sensor, a shut off controller configured to shut off the gas safety valve, a computing device, and a communications module. A server is communicably coupled to the communications modules of the gas safety devices for that implements artificial intelligence (AI) which based on a current threat condition to the gas distribution network determines affected sub-networks. The server is for sending of a valve closing instruction signal to the gas safety device in the first sub-network during the current threat condition when the current threat condition is determined to affect the first sub-network. Responsive to the valve closing instruction signal, the gas safety device shuts off the gas safety valve in the first sub-network.

摘要： A master controller determines a first flow setpoint for a process flow gas and/or a carrier gas flow through a first mass flow controller. The master controller obtains a back pressure setpoint of a distribution manifold and determines a second flow setpoint for the process gas flow and/or the carrier gas flow through a second mass flow controller or a back pressure controller based on the determined first flow setpoint and the obtained back pressure setpoint. The master controller controls the process gas flow and/or the carrier gas flow through the first mass flow controller to the first flow setpoint and the second mass flow controller and/or the back pressure controller to the second flow setpoint. The master controller controls the back pressure of the distribution manifold to the back pressure set point in view of a back pressure reading from a back pressure sensor of the distribution manifold.

摘要： One aspect of the invention provides a computer-implemented method for controlling a swimming pool or spa system. The computer-implemented method includes: creating a data structure representing a plurality of swimming pool system components and fluidic connections between subsets of the plurality of swimming pool system components; receiving a request to control one or more of the plurality of swimming pool system components; calculating fluidic flows through the plurality of swimming pool system components based on one or more potential configurations of the plurality of swimming pool system components capable of fulfilling the request; and detecting whether the one or more potential configurations result in unsatisfactory conditions.

摘要： A system may be configured to monitor an amount of a gas species in a processing chamber using Optical Emission Spectrometry. The gas measurement may be provided as feedback to a control process that generates a target setpoint for a gas flow controller into the process chamber. This real-time process may increase/decrease the flow rate of the gas in order to maintain a process deposition mode within a transition region between primarily metallic deposition and primarily compound deposition.

摘要： Embodiments include systems and methods of in-line mixing of hydrocarbon liquids from a plurality of tanks into a single pipeline. According to an embodiment, a method of admixing hydrocarbon liquids from a plurality of tanks into a single pipeline to provide in-line mixing thereof includes determining a ratio of a second fluid flow to a first fluid flow based on signals received from a tank flow meter in fluid communication with the second fluid flow and a booster flow meter in fluid communication with a blended fluid flow. The blended fluid flow includes a blended flow of the first fluid flow and the second fluid flow. The method further includes comparing the determined ratio to a pre-selected set point ratio thereby to determine a modified flow of the second fluid flow to drive the ratio toward the pre-selected set point ratio. The method further includes controlling a variable speed drive connected to a pump thereby to control the second fluid flow through the pump based on the determined modified flow, the pump being in fluid communication with the second fluid flow.

摘要： A fuel dispensing system includes that receives fuel from a fuel storage tank, and a blending system in fluid communication with the fuel dispensing unit. The blending system including a fuel conveyance device that receives the fuel from the fuel dispensing unit, and an additive conveyance device that pumps a fuel additive to be blended with the fuel based on a volumetric flow rate of the fuel, whereby the blending system provides a product mixture having a known fuel-to-fuel additive ratio. A hose and a nozzle are fluid communication with the blending system to dispense the product mixture.

摘要： A particulate metering system includes an air flow origin and a plurality of particulate accelerators. A single particulate source is in communication with the particulate accelerators. Each of a plurality of operated conveyances can be in operable communication with the single particulate source and one of the particulate accelerators. The system includes a confluence of the air flow and the particulate within the mixing area of each of the particulate accelerators. Each of a plurality of discharges can be associated with the particulate accelerators. The operated conveyances can operate at different rates. The system can include one or more gearboxes adapted to be inverted and controlled by a second drive system. The system and controls provide variable application rates of particulate across rows in a field.

摘要： A characteristic of edible oil used for frying operations may be determined using a sensor such as a spectrometer or capacitive sensor. Other attributes indicative of a prior, present, or future frying operations can be specified, and an analytical model indicative of a composite aging parameter can be applied using one or more attributes along with data obtained from the sensor indicative of oil degradation. Application of the analytical model may be used to trigger various actions relating to oil management, such as ranging from automatically generating a notification to an operator or automatically initiating oil management operations such as top-off, oil removal, or oil replacement in a frying apparatus.
