The invention relates to an electronic component that can be operated by means of an alternating voltage. Said component includes at least one input, at least one output and a pair of electronic sub-components with an identical function. The input(s) of the electronic component is/are coupled to a respective input of the electronic sub-components with an identical function and the output(s) of the electronic component is/are coupled to a respective output of said electronic sub-components. In addition, the electronic component is configured in such a way that at least one output only one output signal of the first sub-component of the pair of functionally identical electronic components can be picked up during a first half-wave of an alternating voltage, whereas only one output signal of the second sub-component of the pair of functionally identical electronic can be picked up during the second half-wave of the alternating voltage.

One embodiment relates to a method for determining a concentration of a molecular species of interest. In this method, electromagnetic radiation is transmitted into a volume of gas within an output exhaust system. The transmitted electromagnetic radiation has a first intensity at a characteristic frequency that is associated with a transition of the molecular species of interest. Electromagnetic radiation is then received from the volume of gas at a second intensity. The method then correlates the first intensity to the second intensity to determine the concentration of the molecular species of interest within the volume of gas. Other methods and systems are also disclosed.

A method is described for producing a structured metal layer used, for example, as an antenna for RF ID tags. The structured metal layer is electrodeposited on a cathode, on the surface of which conducting and non-conducting regions are defined. Applied to the deposited metal layer in a residual volume is an adhesive with which the structured metal layer can be made to adhere firmly on a carrier layer.
摘要:
The circuit element has a first layer composed of an electrically insulating substrate material and a first electrically conductive material which is in the form of at least one discrete area such that it is embedded in the substrate material and/or is applied to the substrate material. Furthermore, it has a second layer having a second electrically conductive material, and a monomolecular layer composed of redox-active bispyridinium molecules, which is arranged between the first layer and the second layer. The bispyridinium molecules are immobilized on the electrically conductive material which is in the form of at least one discrete area, and make electrical contact with the second electrical material of the second layer. Furthermore, electrically inert molecules are immobilized on the first layer, which molecules form a matrix which surrounds the at least one discrete area with the monomolecular layer composed of bispyridinium molecules.
