Abstract: A system and method for an application of a virtual load monitoring of an aircraft to determine a component retirement time for at least one component of the aircraft is provided. The system and method includes estimating component loads from aircraft state parameters; calculating load statistics from the component loads; calculating a reliability factor; generating a component design load spectrum by applying the reliability factor to the load statistics; and calculating the component retirement time for the at least one component of the aircraft by utilizing the component design load spectrum.

Abstract: A system and method are provided to perform loads-based structural health monitoring (LBSHM) of a dynamical system. The method includes receiving, by at least one computer, sensing data responsive to sensing at least one of a parametrical state and a response of the dynamical system, and determining a Koopman mode and a Koopman eigenvalue. The Koopman mode represents a correlation between the sensor data output by the plurality of sensors. The Koopman eigenvalue represents a frequency component associated with the sensor data and growth or decay of energy associated with the sensor data. The method further includes generating, by the at least one computer, an estimation model to determine a linear estimation based on the Koopman mode and the Koopman eigenvalue that estimates a load response of the dynamical system based on growth or decay of energy associated with the sensor data.

Abstract: A squat assistance device. The squat assistance device includes a base having a first side and a second side, a padded back support disposed on the first side of the base, a frame connected to the second side of the base, a plurality of wheels rotatably attached to opposing vertical rails of the frame, a neck support connected to an upper portion of the padded back support, the neck support configured to support configured a user's neck, and one or more weight supports disposed on the second side of the base extending perpendicularly therefrom, wherein the one or more weight supports are each configured to support a weight thereon. Users lean against the padded back rest while the plurality of wheels roll along a vertical surface such as a wall, assisting the user with the performance of the squat and reducing the risk of injury.

Abstract: The present invention provides an apparatus comprising a plurality of planar waveguides and method of making the same. The apparatus includes first, second, and third layers formed above a substrate and adjacent each other. The second layer is formed between the first and third layers of a material and comprises a plurality of organofunctional siloxane-based resin or polymer waveguides. Each waveguide has an input on one edge of the second layer and an output on one edge of the second layer so that the input and output are on different line-of-sight paths. The plurality of waveguides is formed such that intersections of the waveguides occur at approximately right angles and the outputs and inputs located on edges that are opposite one another are offset from each other in a direction that is perpendicular to the direction of the corresponding input or output signal.

Abstract: The present invention provides a planar waveguide. In one embodiment, the planar waveguide includes first and third layers formed above a substrate and adjacent each other. The first and third layers are formed of a first material having a first index of refraction. The planar waveguide also includes a second layer formed between the first and third layers of a second material having a second index of refraction that is larger than the first index of refraction. The planar waveguide further includes a plurality of organo-functional siloxane based resin or polymer waveguides formed in the second layer. Each organo-functional siloxane based resin or polymer waveguide has an input on one edge of the second layer and an output on one edge of the second layer so that the input and output are on different line-of-sight paths.
