The disclosed embodiments relate to the design of a preconcentrator system for preconcentrating air samples. This preconcentrator system includes a plurality of preconcentrators that preconcentrate the air samples prior to chemical analysis, and a delivery structure comprising a manifold that selectively routes a sample airflow to the plurality of concentrators so that the plurality of preconcentrators receive a sample airflow concurrently or individually.

An improved incubator and control apparatus include separate temperature and humidity control loops wherein a commanded temperature and a commanded relative humidity (RH) value are commanded to the control apparatus via a user interface. The control apparatus employs a humidifier rate saturation controller which acts responsive to both a humidity control signal and a current temperature to regulate the addition of humidity to the air within the incubator assembly to avoid a transient humidity from exceeding a predetermined value and thereby avoiding the generation of condensation within the incubator.

A multi-class controller for a wind power generator capable of controlling the operation of the wind power generator in an optimal state under various site conditions and a wind power generation system using same are proposed. The multi-class controller includes: a sensor unit for sensing the environmental conditions of an area where the wind power generator or the power transmission unit to be controlled is installed and a state of a component constituting an object to be controlled, and generating a sensing value; and a control unit for receiving the sensing value to determine an operation state of the object to be controlled, converting a predetermined control default value for controlling the object to be controlled to a control value.
