A device having at least one radiation-emitting semiconductor component, the semiconductor component being assigned at least one electrical heating element designed for heating the semiconductor component. A method of producing a styrene copolymer comprising reacting styrene and at least one alkyl acrylate andor at least one alkyl methacrylate, wherein the alkyl acrylate comprises an alkyl group having from 8 to 12 carbon atoms and the alkyl methacrylate comprises an alkyl group having equal to or greater than 10 carbon atoms. Temporary master keys are derived for low latency handoffs and secure authentication between a new access point and the access terminal. The coprocessor then moves resources from the yielding processor to the resource receiving processor.
