摘要:
A method for measuring the acoustic damping capacity of a specimen (114), such as a layered honeycomb structure, comprises tapping the specimen (114) with a tapping rod (102). The tapping action imparts mechanical energy to the specimen (114). The method further comprises measuring, for a time interval, energy reflected from the specimen (114) as a result of the tapping. The method further comprises creating a time-energy profile (120) based on the energy reflected from the specimen during the time interval. The method further comprises evaluating the time-energy profile (120) to determine the acoustic damping capacity of the specimen (114).
摘要:
The present invention is an apparatus for detecting and treating bruxism. The apparatus of the invention comprises a sensing unit, a calculation unit and a stimulation unit. The sensing unit is in charge of measuring the interocclusal distance and reporting this distance to the calculation unit. After receiving the information from the sensing unit, the calculation unit archives and processes the information to determine if the sensing event is a bruxism event. When a sensing event is confirmed as a bruxism event, the calculation unit selects an adequate stimulation and sends a request to the stimulation unit, which applies the selected stimulation. The apparatus of the present invention may be suitable for treating both diurnal and nocturnal bruxism and the intrabuccal components may be removed from the mouth when bruxism events are not expected to occur, i.e., during the day for an individual who suffers only from nocturnal bruxism.

Die Erfindung betrifft ein Perkussionsinstrument mit einem beweglich gelagerten Stößel (2), der unter Krafteinwirkung auf eine definierte Geschwindigkeit beschleunigt und danach im freien Flug auf ein Prüfobjekt zu bewegt wird. Für die Vor- und Rückwärtsbewegung ist ein elektromagnetischer Antrieb vorgesehen. Der Stößel (2) enthält hierzu einen nichtmagnetischen (22) und einen weichmagnetischen Abschnitt (2b), weicher in eine Magnetspule (10) eintaucht Eine Steuerelektronik (12) liefert Stromimpulse an die Spule (10). Mittels einer Meß- und Auswerteeinrichtung (13) wird die Geschwindigkeit des Stößels (2) erfaßt und nach Soll-Istwertvergleich auf konstanter Größe gehalten. Bei Erreichen der Sollgeschwindigkeit wird die Stromzufuhr zur Spule (10) abgeschaltet.
