Abstract: A vehicle occupant protection device includes a safety-relevant means which can assume at least two different conditions. The vehicle occupant protection device further comprises a reading device (12) including an antenna (13), and a transponder (10) which, in dependence on the respective condition of the safety-relevant means or in dependence on a change in condition, produces a characteristic reaction detectable by the reading device (12). A coupling means (30) is arranged between the antenna (13) of the reading device (12) and the transponder (10). The coupling means (30) collects, diverts and again emits at least part of the energy emitted by the antenna (30) of the reading device (12).

Abstract: The brush for use on a dental rotary hand piece comprises a bristle field in which the length of the bristles decreases from the external radius of the bristle field towards its center. A brush of this kind allows improved finishing, polishing, and cleaning of interdental spaces and fissures in the chewing surface.
