Abstract: A power transfer system and method are provided for transferring power from an AC supply outputting a first AC voltage. The system includes a controller and a matrix converter coupled to the AC supply for converting the first AC voltage to a second AC voltage. A primary coil is connected to the matrix converter and a secondary coil is in communication with the primary coil for producing an induced AC voltage. A secondary rectifier is connected to the secondary coil for rectifying the induced AC voltage to produce a secondary DC voltage. A sensor is coupled to the secondary rectifier and to the controller for monitoring the secondary DC voltage and outputting a proportional signal. The controller is configured to control the matrix converter producing a desired second AC voltage at a desired operating frequency and maintain a predetermined secondary DC voltage in response to the signal from the sensor.

Abstract: A system for measuring total operating deflection shapes of a structure includes one or more imagers, each including two cameras spaced apart from one another and each oriented and positioned to have corresponding fields of view of a different corresponding section of the structure, with the corresponding sections that may include overlap area of the structure within each of the different sections of the structure. Each of the cameras generates a corresponding data stream, which is communicated to a controller, which is configured to measure the response of the structure to an excitation, such as a vibration or an impulse. The system is configured to convert time-domain data from each of the data streams to the frequency-domain data using a Fourier Transform algorithm and stitching the shapes to obtain the total operating deflection shapes of the structure by scaling and stitching together the frequency-domain data.

Abstract: In general, coated fibers, methods of bonding a coating to fibers, and composite materials prepared from coated fibers are provided. The coated fiber is created with a surface that is compatible with and bonds to the polymer resin used in composite materials. In another aspect, the coating may exhibit additional functionality, such as water repellency, fire resistance, or odor control. More specifically an atmospheric pressure plasma process is applied to the fibers to bond coating materials to the fiber surface and to cure the coating surrounding the fiber surface. Optionally, radiation is used in the process to cure the coating. Finally, composite materials and parts may be made from the coated fibers that exhibit high strength and improved mechanical properties over composites made with uncoated fibers. Alternatively, a natural fiber reinforced composite material is made from coated natural fibers that has improved mechanical properties and decreased water absorption.

Abstract: A fiber-optic force and displacement sensor includes a mirror comprising a plurality of sectors extending from a center point to a peripheral edge. Each of the sectors has a high reflectance corresponding to only one of a plurality of single wavelength light beams having different wavelengths transmitted from a laser light source. A method of measuring force and displacement includes measuring the radiant flux between each of a plurality of reflected single wavelength light beams that change as the area of the sectors are displaced towards and away from a center of projection of a combination light beam that comprises the plurality of single wavelength light beams projected towards the center point of the mirror when the mirror is in a rested position. Forces acting upon the mirror are measured as a function of the displacement of the mirror and the transverse and the axial stiffness of a connector.
