摘要： Controlling flow of gas in a gas pipeline network, wherein flow within each pipeline segment is associated with a direction (positive or negative). Minimum and maximum signed flow rates are calculated for each pipeline segment constituting lower and upper bounds, respectively, for flow in each pipeline segment. A nonlinear pressure drop relationship is linearized within the lower and upper flow bounds to create a linear pressure drop model for each pipeline segment. A network flow solution is calculated, using the linear pressure drop model, and includes flow rates for each pipeline segment to satisfy demand constraints and pressures for each of a plurality of network nodes to satisfy pressure constraints. Lower and upper bounds on the pressure constraint comprise a minimum delivery pressure and a maximum operating pressure, respectively. The network flow solution is associated with control element setpoints used by a controller to control one or more control elements.

摘要： A gas delivery system for a plasma process system such as a plasma etching system wherein inner surfaces of gas passages are coated with a corrosion-resistant material coating formed by curing a layer of fluidic precursor deposited on the inner surfaces. The coating can be formed by (a) flowing a fluidic precursor of a corrosion-resistant material through the gas passages and depositing a layer of the fluidic precursor to completely coat the inner surfaces of the gas passages; (b) removing excess fluidic precursor from the inner surfaces; (c) curing the deposited layer of the fluidic precursor to form a corrosion-resistant material coating.

摘要： A method for underground pipeline monitoring in which a continuous alternating electrical current having a current frequency in a range of about 1 kHZ to about 8 kHz is imparted onto a pipeline, producing an alternating magnetic field at the current frequency along the pipeline. Distributed along the pipeline is a network of RFID tag sensors which absorb an amount of energy from the alternating magnetic field. The impedance of the sensors is modulated, producing a modulated sensor impedance which is detected at a location proximate the location at which the continuous alternating electrical current is imparted onto the pipeline.

摘要： A method of detecting and responding to a threat condition includes receiving, at a sensing module, an input acquired in proximity to a pipeline of a fluid distribution system, the input including data associated with a vibration measurement of the pipeline acquired by a sensor exterior of the pipeline. The method also includes determining whether the input indicates a threat condition by comparing the data to a previously recorded baseline vibration measurement. The method further includes automatically closing a first fluid transmission valve in response to a determined threat condition, thereby restricting flow of fluid through the pipeline in a vicinity of the first fluid transmission valve, and wirelessly transmitting a message for receipt by a control module that is remote from the sensing module, the message including indications of the determined threat condition, the first fluid transmission valve, and an identifier associated with the sensing module.

摘要： Techniques are disclosed for preventing unneeded interruption of industrial processes. Spike trap logic used to delay the occurrence of a trip or interlock when a registered signal exceeds a threshold for a minimum period of time. Doing so prevents trips or interlocks from occurring for transient or intermittent signals, which may be the result of poor sensor readings, poor configuration, or actual, but brief, spikes that should not result in a tripped process or machine. That is, rather than simply tripping—or interlocking—when a trip signal is initially observed, the spike trap logic introduces a delay between when a trip signal is received and when an interlock or trip event actually happens. If the signal remains high for delay period, a trip occurs. Otherwise, the trip signal is considered an intermittent or transient spike and does not result in a trip.
