The present invention describes methods, systems, and apparatuses for controlled delivery of wellbore fluids including analysis and treatment within the methods, systems, and apparatuses themselves.

A chemical liquid preparation method of preparing a chemical liquid for treating a film formed on a substrate, including a gas dissolving process in which an oxygen-containing gas and an inert-gas-containing gas are dissolved in the chemical liquid by supplying the oxygen-containing gas which contains oxygen gas and the inert-gas-containing gas which contains an inert gas to a chemical liquid, wherein in the gas dissolving process, a dissolved oxygen concentration in the chemical liquid is adjusted by setting a mixing ratio between the oxygen-containing gas and the inert-gas-containing gas supplied to the chemical liquid as a mixing ratio corresponding to a predetermined target dissolved oxygen concentration.

Apparatus control system includes control device controlling operation of apparatuses and portable mobile terminal communicable with the control device. In the control device, control unit controls each apparatus in accordance with control schedule stored in device-side storage unit and control request from the mobile terminal. In the mobile terminal, date and time setting unit sets arbitrary date and time as set date and time. Terminal-side storage unit stores terminal-side schedule in which control contents are associated with control dates and times for each apparatus. Simulation unit simulates operating state of each apparatus assuming that the apparatus is operating at the set date and time set by the date and time setting unit, using the terminal-side schedule. Apparatus state reflection unit outputs control request to the control device to cause the control device to control each apparatus such that the apparatus is in the operating state simulated by the simulation unit.

A method for controlling an inverter is provided, the method including, setting, as a first reference, a pressure data returned from the pressure sensor when a pre-PID ends, updating the first reference that is increased by a predetermined step to a second reference, determining an output frequency of the inverter by performing a PID control using the second reference, and determining an output frequency of the inverter by performing the PID using a third reference set up by the user when the second reference or feedback pressure data is equal to a set value.

A respiratory device, such as a ventilator, for use in treating respiratory disorders and for preventing respiratory disorders. The respiratory device is configured to be powered from a range of different power sources including an internal battery, an external battery, AC power source or a DC power source. The device may be electrically connectable to a plurality of external batteries in a series and the power from each external battery is used sequentially along the series. A controller of the respiratory device is configured to detect the connection of the different power sources and control use of the different power sources using a power priority scheme. The controller may determine an estimate of the total available battery capacity from all the electrically connected batteries and display the total battery capacity on a user interface display of the device.

An electronic valve controller for an open-loop and closed-loop control of a valve island includes four or eight valve disks having pneumatic valves configured to perform a motion task. Applications for the open-loop and closed-loop control of the valve island can be loaded onto the electronic valve controller. The invention further relates to a valve assembly, which is controlled in an open-loop and closed-loop manner by an electronic valve controller, to a corresponding method, and to a system.

A virtual power plant is presented. A virtual power plant couples to one or more virtual power plant units that provide power and/or storage of power to a power grid. In some embodiments, a method of operating a virtual power plant includes receiving a request from a requester; determining whether the request can be performed by a set of units; reporting the result to the requester; and if a subsequent execution request is received from the requester, then executing the request.

An apparatus for adjusting the partial pressure of gaseous mixtures comprises a housing and piston. The housing defines a chamber coupled to an oxygen metering orifice, diluent metering orifice, vent port and gas outlet. The oxygen metering orifice provides oxygen to the chamber and the diluent metering orifice provides diluent gas to the chamber. The piston is movably positioned in the chamber and includes first and second sealing devices. The chamber is sectioned into a mixing chamber, a diluent chamber and a reference chamber located between the mixing chamber and diluent chamber. The diluent chamber receives a diluent gas referenced at ambient pressure and the reference chamber is charged with a gas having a reference pressure. The piston changes positions within the chamber depending on a force balance created by a pressure differential between the reference pressure and ambient pressure.

A system to interrupt the line or supply side power or charged system of any building, appliance, process, and the like, so as to render the system without charge or current output outside of the junction box/enclosure or equipment load supply connection so that emergency first responders or solar/any technician, authorized personnel in any field, system maintenance crew may avoid electrocution, chemical or machine/appliance hazard in the presence of fire, explosion, structural failure/compromise, moisture, flammables, caustics, hazmat, water stream, mist, fogging, physical damage or servicing of the system. The system can be engaged for any anticipated disaster such as fire, hurricane, tornado, earthquake, flood, and the like.
