The invention relates to a security element, in particular for security labels or adhesive strips, consisting of the following layers: a) a carrier substrate b) a reflective layer or a layer with a high refractive index c) a partial separating lacquer layer d) on all-over adhesive coating. A device is provided that comprises a wall-flow filter having inflow channels and outflow channels, which are connected by pores. The received set of radio settings may identify one or more parameters for evaluating the radios. The film is then preferably crystallized by a low-temperature anneal at, for example, about 560 degrees for about twelve hours. In order to bind fumes containing fluorine andor phosphorous, for example in the event of fires of lithium-ion batteries, the composition includes at least one alkaline-earth carboxylate, in particular calcium carboxylate, of one or more carboxylic acids. In an example, provided is a method for digitally representing an analog input signal.
