Appl. No.:

12/795538

Inventors:

Neil J. Goldfine - Newton MA, US
Yanko K. Sheiretov - Waltham MA, US
Andrew P. Washabaugh - Chula Vista CA, US

Assignee:

Jentek Sensors, Inc. - Waltham MA

International Classification:

G06F 19/00

US Classification:

702183

Abstract:

A framework for adaptively managing the life of components. A sensor provides non-destructive test data obtained from inspecting a component. The inspection data may be filtered using reference signatures and by subtracting a baseline. The filtered inspection data and other inspection data for the component is analyzed to locate flaws and estimate the current condition of the component. The current condition may then be used to predict the component's condition at a future time or to predict a future time at which the component's condition will have deteriorated to a certain level. A current condition may be input to a precomputed database to look up the future condition or time. The future condition or time is described by a probability distribution which may be used to assess the risk of component failure. The assessed risk may be used to determine whether the part should continue in service, be replaced or repaired. A hyperlattice database is used with a rapid searching method to estimate at least one material condition and one usage parameter, such as stress level for the component.

US Classification:

707736, 702181, 738658, 324238, 73632, 707E17005

Abstract:

Methods and apparatus for enhancing performance curve generation, damage monitoring, and improving non-destructive testing performance. Damage standards used for performance curve generation are monitored using a non-destructive testing (NDT) sensor during a damage evolution test performed with the standard. The evolution test may be intermittently paused to permit ground truth data to be collected in addition to the NDT sensor data. A damage evolution model may be used to estimate ground truth data during the intervening periods of the damage evolution test. The NDT sensor data and ground truth data are used to generate performance curves for the NDT system. Multiple sensors may be monitored at multiple locations on the damage standard and multiple damage evolution tests may be performed with multiple damage standards.

Inventors:

David A. Jablonski - Whitman MA

International Classification:

B22F 312
B22F 704

US Classification:

419 8

Abstract:

A method for manufacturing cutting knives, in particular granulator knives in which a mass of highly wear resistant material is bonded along one edge of a main body of a tougher, more ductile material, the cutting edge machined into the mass of wear resistant material, to increase the service life of the knife between sharpenings without subjecting the tool to breakage during heavy use in a granulator.

International Classification:

C08L 67/04
C08L 67/02

Abstract:

In various embodiments, the present invention provides polymeric compositions that combine polylactic acid (PLA) (or heteropolymers of lactic acid) with additives (organic or inorganic), such as elastomeric additives and/or co-polymer additives. Such polymeric blends may exhibit improved mechanical properties and/or degradation rates compared to PLA homo-polymer (or a lactic acid heteropolymer).
