Randomly distributed light pattern generating method for e.g. advertising application, has battery, where random sequences are dimensioned such that light pulse pattern is generated and pattern is unforeseeable for observer

摘要

The arrangement has a battery, carrier substrate and a light pattern that is determined by a time interval between two light pulses and a pulse duration, where the time interval and the pulse duration are determined by a configurable pseudo random generator that is operated with a fixed clock frequency. The random sequences are dimensioned in such a manner that a light pulse pattern is generated, where the pattern is unforeseeable for an observer.
