Abstract

Bekannte Anordnungen und Verfahren erlauben keine drahtlose Energiefernversorgung, wenn der Informationsträger im Innneren eines dickwandigen und/oder metallischen Körpers angebracht ist, da Energiestrahlung auf der Basis elektromagnetischer Wellen in diese schlecht oder nicht eindringt und berührungslos übertragener Ultraschall nicht effektiv in Körper eindringt. Die Anordnung besteht im wesentlichen aus einem Basisgerät (1), das über eine akustische Sendeeinheit (3) verfügt, die sich in loser Kontaktverbindung durch eine oberflächlich-körperliche Berührung zu einem Funktionsgegenstand (4) befindet. In diesem Funktionsgegenstand (4) befindet sich in einer akustisch festen Kopplung der Informationsträger (5). Dadurch ist ein geschlossenes, akustisch gut verkoppeltes Gesamtsystem gegeben, das sowohl eine effektive Energie- als auch Informationsübertragungen auf akustischem Wege gewährleistet. Code- und Informationsübertragung im elektronischen Zutritts-/Zugriffsbereich, Produktkennzeichnung.
