Abstract: Systems and methods for modeling stress intensity solutions of integrally stiffened panels are disclosed. In one embodiment, a method includes serving a process over the internet. The process includes taking a problem definition, automatically forming a finite element model at least partially based on the problem definition, automatically verifying a suitability condition of the finite element model, automatically solving a computational solution using the finite element model and automatically validating the computational solution. In one aspect, providing a problem definition includes at least one of providing a geometry definition, providing a crack definition, and providing load and constraint definition.

Abstract: Systems and methods for analyzing structural test data are disclosed. In one embodiment, a method includes applying a sequence of loads to a test article, receiving raw test data indicative of the applied loads from at least one sensor operatively associated with the test article, receiving predicted test data indicative of the predicted loads on the test article, filtering out invalid test data, cycle counting to pair loads in the test data, performing a first fatigue damage computation based on the raw test data, performing a second fatigue damage computation based on the predicted test data, and comparing the first and second fatigue damage computations. The filtering, cycle counting, and performing of the first and second fatigue damage computations, and the comparison of the first and second fatigue damage computations, may be performed simultaneously using a spreadsheet program.

Abstract: A mattress configured to support a patient including a foot section having a leg portion, a heel pressure relief portion, and a raised calf support portion positioned intermediate the leg portion and the heel pressure relief portion.

Abstract: A method of monitoring a feature of a blast such as velocity of detonation (VOD) comprises the steps of providing a detonator 16.1 at a blast site 12. Prior to the blast, a blast control signal path 20, 18.1 is utilized to communicate blast control signals to the detonator. During a period following start of the blast, a blast feature signal communication path 18.1, 20 comprising at least part of the blast control signal path is utilized to communicate a blast feature signal relating to the feature to a remote blast feature monitoring station 26. The blast feature signal is generated by generating a monitoring signal in a conductor arrangement 18.1 connected to die detonator, utilizing a sensor outside of the housing of the detonator to sense changes in a blast feature monitoring parameter of the monitoring signal, and transmitting data relating to the changes to the station 26.

Abstract: A patient support including a frame and a mattress supported by the frame. The frame includes a deck support and a deck supporting the mattress.

Abstract: Air from the intake manifold and fuel from an injector is mixed by a Venturi of adjustable flow path, upstream of an intake valve. Fuel is injected into the throat of the Venturi to improve vaporization and to premix the fuel and air before the mixture enters the combustion chamber. A pressurized manifold from a supercharger or turbocharger system can enhance the action of the Venturi. The Venturi mixing enhances combustion efficiency, resulting in increased power and fuel economy for an internal combustion engine.

Abstract: A data query and reporting method and system are provided. The method and system allow non-technical computer users to build and execute complex database queries. The method and system accommodate the need for a simple, easy-to-understand interactive and iterative means for generating and validating database queries. The method and system reduce the complexity and costs associated with retrieving useful information for organizations of all sizes, especially smaller businesses. The method and system support a robust security model, enabling organizations to protect sensitive data while providing broad data access.

Abstract: A method and system for creating and following drill links in a report are disclosed. A relational abstraction of a data store is defined, the definition including a plurality of views, scalar or aggregate fields associated with the views, and relations between the views. A report is generated that includes at least one drill link associated with a sequence of one or more relations originating at a base view of the relational abstraction. Upon selecting a drill link contained in a first report, information about the drill link is extracted from the report, and the extracted information and the destination view associated with the drill link are used to create a second report.

Abstract: A method and system for displaying a relational abstraction data store are disclosed. A relational abstraction of a data store is defined, the definition including a plurality of views, scalar or aggregate fields associated with the views, and relations between the views. The fields and relations associated with views are displayed and related to a base view through a sequence of relations. The fields displayed are constrained based upon the sequence of relations from the base view. Scalar fields are displayed where the sequence of relations does not contain a to-many relation. Aggregate fields are displayed where the sequence of relations contains at least one to-many relation. Distinct aggregate fields are displayed where the relation path sequence contains a to-many relation followed by a many-to-one relation. A field may be displayed with additional information indicating how, or whether, the fields may be used. The display of fields may be constrained in predetermined ways.
