US Patent:

7777112, Aug 17, 2010

Filed:

Sep 10, 2007

Appl. No.:

11/900068

Inventors:

Thomas O'Connor - Deerfield Beach FL, US

International Classification:

G10D 13/02

US Classification:

84411R, 84411 A

Abstract:

A drumhead with an outer ring member anchored to the outer periphery of a drum and having a threaded interior surface. An inner ring member having a threaded exterior surface matingly threaded to the interior surface of the outer ring. Rotating the inner ring in a first direction relative to the outer ring, increases the tension exerted on the drum skin. Similarly, rotating the inner ring in a second direction relative to the outer ring decreases the tension exerted on the drum skin. Vertical pressure is exerted on the drum skin and drum ring when the inner ring is rotated in a first direction relative to the outer ring. Conversely, the pressure is released on the drum skin and the drum ring when the inner ring is rotated in a second direction relative to the outer ring.

Abstract:

Detection of event conditions in an industrial plant includes receiving process data corresponding to one or more sensors, estimating normal statistics from the process data, estimating abnormal statistics from the process data with potentially abnormal operation of the one or more components, determining a fault model from the estimated normal and abnormal statistics, the fault model including a learning matrix, one or more fault indices indicating a likelihood of an occurrence of one or more fault events, and a fault threshold corresponding to the one or more sensors, determining one or more further fault indices from the further process data; applying the fault threshold to the one or more further fault indices, and indicating a further occurrence of the one or more fault events when a magnitude of the one or more further fault indices exceeds the fault threshold corresponding to the one or more sensors.
