A system for flare combustion control includes a sound speed measurement device for measuring sound speed in a flare vent gas, and a flare combustion controller including a memory and a processor. The processor is configured to receive the measured sound speed and determine, based on the measured sound speed, a molecular weight of the flare vent gas. The processor is further configured to determine, based on the determined molecular weight, a net heating value of the flare vent gas, and adjust the net heating value of the flare vent gas by regulating an amount of a supplemental fuel gas in the flare vent gas.

A theme park permits interactions between visitors and remote viewers in Mixed Reality. The park has devices controllable by visitors and viewers. A viewer uses an app to interact. A visitor can use an app on a mobile device. Viewers watch or follow a visitor (akin to esports). A viewer can change physical aspects at the park. Including opening and closing a door or window, moving a vehicle, adjusting a fountain. Visitor and viewer can form a team. A viewer can aid or hinder a visitor. Visitor and viewer can trade virtual assets. The park makes a movie for a theatre. The viewer watches the movie and captures items that the visitor uses in the park. There can be multiple Mixed Realities.

A cleaning apparatus that includes a cleaning member and cleans a detection surface of a detection element included in a detection device includes a fixing unit configured to fix the detection device attached to the cleaning apparatus, an adjustment mechanism configured to adjust a position of the detection device with respect to the cleaning apparatus and a measurement unit configured to measure a position and an inclination of the detection element of the detection device.

A computer-implemented method of closed-loop dissolved oxygen monitoring and control at a hydroelectric plant includes: regulating at least one aeration valve coupled to a turbine using pattern recognition; wherein a target parameter for the regulating is a dissolved oxygen concentration of water downstream of the hydroelectric plant. The dissolved oxygen concentration may be at least 5.0 milligrams per liter. The pattern recognition may be performed using a neural network.

An electrical kitchen appliance for preparing food has an operator control unit for entering control instructions for control of the electrical kitchen appliance by a user. The operator control unit can be removably attached to the electrical kitchen appliance and, in the process, can be operated in a first operating mode and in a second operating mode, wherein the operator control unit for entering control instructions for control of the electrical kitchen appliance by the user is attached to the electrical kitchen appliance in the first operating mode and is removed from the electrical kitchen appliance in the second operating mode. An electrical kitchen appliance of this kind which has an operator control unit which can be individually operated is provided in this way.

Embodiments herein provide methods of monitoring temperatures of fluid delivery conduits for delivering fluids to, and other components external to, a processing volume of a processing chamber used in electronic device fabrication manufacturing, and monitoring systems related thereto. In one embodiment, a method of monitoring a processing system includes receiving, through a data acquisition device, temperature information from one or more temperature sensors and receiving context information from a system controller coupled to a processing system comprising the processing chamber. Here, the one or more temperature sensors are disposed in one or more locations external to a processing volume of a processing chamber. The context information relates to instructions executed by the system controller to control one or more operations of the processing system.

A method for supplying cutting oil which is able to attain the above object by adopting the following processes in a machine tool for cutting work pieces. a. setting of individual cutting times to each work piece and selection of cutting oil to be used, b. setting of a quantity of the cutting oil supplied per unit time to a cutting area where the cutting oil selected by the process a is used, c. supplying the cutting oil to a cutting-oil tank, with a state kept that the cutting oil remains in the cutting-oil tank, and d. supplying the cutting oil to the cutting area on cutting each of the work pieces by setting a quantity of the cutting oil as a quantity obtained by multiplying individual cutting times according to the process a with a cutting quantity per individual unit times according to the process b.

An example electromotive linear drive mechanism for moving walkways for conveying people or objects may comprise a long stator as an active primary part positioned along a direction of movement of a moving walkway, as well as a plurality of passive secondary parts that are movable with respect to the active primary part and are arranged with one another along the direction of movement. The long stator may have a plurality of successive long stator sections in the form of coil groups along the direction of movement. Each long stator section may have its own control device that is configured to move the secondary parts using control parameters stipulated for the respective long stator section. Further, example methods for operating the electromotive linear drive mechanism may involve predefining different movement profiles for the respective control devices for at least some of the long stator sections such that the secondary parts move along the long stator in a non-uniform manner.
