Abstract: A system for dynamically controlling an output environment comprising a computer unit and at least one output means controllable by the computer unit, wherein the system is configured to output an output generated by the computer unit via the output means in the output environment, wherein the system comprises at least two wearables each attachable to one person, wherein the wearables are connected to the computer unit and configured to substantially continually detect and transmit to the computer unit at least one physiological parameter of the person wearing the respective wearable, and the computer unit is configured to control the output based on all physiological parameters detected by the wearables.

Abstract: The device for metering fluid mixtures, in particular liquids containing a gas such as carbon dioxide, includes a flow sensor, a metering valve, and a controller that drives the metering valve as a function of a set point and of the flow rate measured. The flow sensor has an impeller wheel having a horizontal axis, the fluid mixture being guided on an arcuate path on the periphery of the impeller wheel, the path being directed from bottom to top. Despite the presence of gas, a precise metering is achieved.
