verschiedenen Zeitpunkten die mit t bezeichnet sind. Das Lebewesen, dessen different points in time which are denoted by t. The living thing whose
Pulsschlag bestimmt werden soll ist, ist mit L bezeichnet. Das Messgerät, mit dem dasPulse rate is to be determined is denoted by L. The meter with which the
Laufzeitverfahren durchgeführt wird, ist mit M bezeichnet. Mit M können Signale ausgesendet und empfangen werden. Mit S und S' werden die zum Laufzeitverfahren verwendeten Signale bezeichnet. Die zeitlichen Abtastintervalle zwischen den Run-time method is performed, is denoted by M. With M signals can be sent and received. S and S 'are the signals used for the transit time method. The temporal sampling intervals between the
Zeitpunkten t und die minimale Messfolgedauer sind so gewählt, dass der Pulsschlag von L ermittelt werden kann. Times t and the minimum measurement duration are selected so that the pulse beat of L can be determined.
Zum Zeitpunkt ti hat das von M ausgesandte Signal S L erreicht. Zum Zeitpunkt t2 ist S von L zu M zurückgekehrt. Zum Zeitpunkt t3 hat ein neues, von M ausgesandtes Signal S' L erreicht. Zu diesem Zeitpunkt hat sich das Volumen eines Teils von L verändert. Mit der Änderung des Volumens geht eine Änderung des Ortes der Hautoberfläche an diesem Teil von L einher. Ursächlich für die Volumenänderung und damit auch für die Veränderung eines Ortes der Hautoberfläche ist der Pulsschlag von L. Zum Zeitpunkt t4 ist S' von L zu M zurückgekehrt. Da die Geschwindigkeit, mit der S und S' zwischen M und L übertragen werden, bekannt ist, kann über eine Messung der Zeitdifferenzen (ti - 12) und (t3 - 14), sowie über einen Vergleich dieser Zeitdifferenzen die Änderung des Abstands zwischen L und M bestimmt werden. Die Abstandsänderung wird zur Bestimmung der Änderungen des Ortes der Hautoberfläche von L verwendet, die bestimmte Änderung des Ortes lässt auf den Pulsschlag von L schließen.

At time t 3 , a new signal S 'emitted by M has reached L. At this time, the volume of part of L has changed. The change in volume is accompanied by a change in the location of the skin surface at this part of L. The reason for the change in volume and thus also for the change of a location of the skin surface is the pulse beat of L. At time t 4 , S 'has returned from L to M. Since the speed with which S and S 'are transmitted between M and L is known, the measurement of the time differences (ti - 1 2 ) and (t 3 - 1 4 ), as well as a comparison of these time differences, the change of Distance between L and M can be determined. The change in distance is used to determine changes in the location of the skin surface of L, the particular change in location suggests the pulse beat of L. Temporal changes in the location of the skin surface of L, not by the
Pulsschlag von L verursacht wurden, können einer Frequenzanalyse unterzogen und entsprechend bewertet und berücksichtigt werden. Ferner können zur Bewertung und Berücksichtigung zeitlicher Änderungen des Ortes der Hautoberfläche von L, die nicht durch den Pulsschlag verursacht wurden, weitere Filterverfahren und/oder Informationen über das Fahrverhalten und/oder den Fahrzeugzustand verwendet werden. Die Informationen über das Fahrverhalten und/oder den Fahrzeugzustand können vorzugsweise Systemen zur Fahrzeugzustandsbewertung und/oder Systemen zur Fahrzeugdynamikregelung, beispielsweise einem Elektronischen Pulse beat caused by L, can be subjected to a frequency analysis and evaluated accordingly and taken into account. Further, in order to evaluate and account for temporal changes in the location of the skin surface of L which were not caused by the pulse beat, further filtering methods and / or Information about the driving behavior and / or the vehicle condition can be used.
