In order to produce results for the query, an event structure is defined for each requested event type. The lift assemblies are extendible in a vertical direction. Typically usable components comprise oxidized starch and polymer having reactive primary or reactive secondary amine groups. The input signal replicas may also be modified in way which changes their amplitude or they may be filtered to provide the desired delaying. Above the sequence of semiconductor layers there is a stepped window layer, which is structured in the manner of a Fresnel lens and has with regard to the coupling out of radiation the function of a hemispherical lens.
