Abstract: A method for producing a switching module that comprises at least one electronic component and at least one cooling element configured to cool the at least one electronic component is disclosed. The method comprises coupling the at least one electronic component with the at least one cooling element, inserting the at least one electronic component and the at least one cooling element into an injection mold, positioning a spring element between the at least one electronic component and an inner side of the injection mold, the spring element being supported on the inner side of the injection mold such that the at least one cooling element is pressed against a wall of the injection mold, and at least partially encapsulating the at least one electronic component and the at least one cooling element with a plastic.

Abstract: This invention relates to a method that makes the measurement of a trace gas concentration invariant or at least less affected to pressure variations in the gas and atmospheric pressure changes. This method neither requires a pressure sensor nor a pressure calibration routine. Furthermore, the method can be applied to other gas species present in the background gas or to the background gas itself that cross-interfere with the target gas of interest. This allows removing any pressure dependency of cross-interference parameters of other gas species and/or the background gas. The new method for accurately measuring a gas concentration is based on optimizing the wavelength modulation amplitude of the laser to minimum pressure dependency.
