English term or phrase: once / twice-per-revolution signature
Hallo,

könnte mir jemand sagen, ob ich mit "einer Signatur bzw. zwei Signaturen pro Umdrehung" richtig liege bzw. was der korrekte DE Ausdruck dafür wäre?

Hier das gesamte Patent zwecks Kontext:
http://worldwide.espacenet.com/publicationDetails/descriptio...
Allerdings stimmt der Text nicht genau mit meiner Version überein, deshalb hier noch ein paar weitere Sätze mit dem gesuchten Begriff, die in der Online-Version nicht zu finden sind:

In an embodiment, the piston 218 is cycled at a known rate and a once-per-revolution signature identified in a frequency analysis of the monitored pressure data, corresponding to an exhaust valve leak during either the suction or compression stroke. In other embodiments, a twice-per-revolution signature may be identified if the exhaust valve leaks during both the suction and compression strokes of the piston.

As noted above, the monitored crankcase pressure is expected to rise and fall as the piston cycles within the cylinder. The monitored crankcase pressure thus includes a periodic variation that corresponds to a once-per-revolution signature associated with the movement of the piston. As shown in graph 1000 of FIG. 10, a piston blow-by condition may produce an additional peak 374 (also referred to as a blow-by condition). The blow-by condition is therefore identifiable in a frequency analysis based upon the rate at which the compressor is operated. In one embodiment, the blow-by condition may result in a detectable change in the once-per-revolution signature. In other embodiments, the blow-by condition may result in a detectable twice-per-revolution signature.

In an embodiment, the reservoir pressure can be monitored by the pressure sensor 185, the changes, data (e.g., pressure readings, pressure signatures, measurements of pressure, among others) can be evaluated by the detection component 128 (illustrated in FIGS. 1, 2, among others), and the controller 130 can adjust the compressor 110 based upon the evaluation and/ or monitored pressure.

In an embodiment, detecting a leak condition of the exhaust valve of the cylinder includes recognizing a once-per-revolution signature in a frequency analysis of the monitored pressure, wherein the once-per-revolution signature corresponds to a rate at which the piston is actuated within the cylinder.

In an embodiment, the controller is further configured to recognize a once-per-revolution signature in a frequency analysis of the monitored pressure, wherein the once-per-revolution signature corresponds to a rate at which the piston is actuated within the cylinder.

einfacher / zweifacher (charakteristischer) Kennlinienausschlag pro Umdrehung
Explanation:
Es werden während des Kompressorhubes anhand der Kennlinienaufnahme bzw. anhand der hierfür charakteristischen Kennlinienausschläge Lecks festgestellt (Frequenzanalyse). Text (nicht nur die Wörter...) nochmal gründlich durchlesen und entscheide, ob das zutrifft (ich denke schon).
