Patent number: 8920627Abstract: An embodiment of the invention generally relates to an FET-based detector for carbon monoxide which is based on two sensitive layers. In at least one embodiment, the first of the sensitive layers is catalytically active and therefore reacts equally to alcohols, in particular ethanol, and carbon monoxide. The second of the sensitive layers is not catalytically active and therefore does not react to carbon monoxide, but only to ethanol. The concentration of carbon monoxide can be deduced from the comparison of the signals of the two layers. The two sensitive layers are implemented via similar metal oxide layers, an additional layer having a catalyst such as palladium being provided for the catalytically active layer. Alternatively, two different layers can be used, one of which is already catalytically active without an additional layer.Type: GrantFiled: March 30, 2010Date of Patent: December 30, 2014Assignee: Siemens AktiengesellschaftInventors: Maximilian Fleischer, Ulrich Hoefer, Roland Pohle, Stefan Stegmeier

Patent number: 8888976Abstract: The present invention is directed to a corrosion resistance evaluator suitable for corrosion testing coated metals substrates, such as autobodies. A corrosion resistance evaluator provided with a chamber containing electrolyte to which anode and cathode coated with protective coating being tested are exposed. These coatings are provided with predetermined and standardized defects, such as micro-holes to accelerate the corrosion of the underlying metal substrate in a predictable and repeatable manner. The coated cathode/anode pair is subject to a start-up period followed by series preset DC voltages for preset durations that are interspaced with recovery periods. The impedance date collected is then used to arrive at the corrosion performance resistance of the coating applied over the cathode/anode pair. The foregoing evaluator substantially reduces the time required to test corrosion from several days (40 plus days) to few days (about two days).Type: GrantFiled: January 4, 2010Date of Patent: November 18, 2014Assignee: Axalta Coating Systems IP Co., LLCInventors: Shi Hua Zhang, Lorenzo Fred Pelosi, Robert C.
