20090204355 | METHODS AND APPARATUS FOR MODAL PARAMETER ESTIMATION - In accordance with one embodiment of the present invention, a system for extracting modal parameters of a structure includes an analysis module configured to estimate the modal parameters by computing only a subset of the autospectral matrix of the input data and then solving for the adjoint solution to extract a matrix denominator polynomial. In accordance with another aspect of the invention, orthogonal polynomials are used for the instrumental variables to estimate the matrix polynomial from which the modal parameters are extracted. | 08-13-2009 |

20110293171 | METHODS AND APPARATUS FOR HIGH-RESOLUTION CONTINUOUS SCAN IMAGING - A continuous scanning method employs one or more moveable sensors and one or more reference sensors deployed in the environment around a test subject. Each sensor is configured to sense an attribute of the test subject (e.g., sound energy, infrared energy, etc.) while continuously moving along a path and recording the sensed attribute, the position, and the orientation of each of the moveable sensors and each of the reference sensors. The system then constructs a set of transfer functions corresponding to points in space between the moveable sensors, wherein each of the transfer functions relates the test data of the moveable sensors to the test data of the reference sensors. In this way, a graphical representation of the attribute in the vicinity of test subject can be produced. | 12-01-2011 |

20130006271 | Fasteners, Deployment Systems, and Methods for Ophthalmic Tissue Closure and Fixation of Ophthalmic Prostheses and Other Uses - Methods and devices for ophthalmic tissue closure and fixation of ophthalmic prostheses are provided. In accordance with some embodiments, devices for both grasping and clipping a plurality of ocular tissue and ocular prostheses are provided. Various device embodiments are provided for both malleable clips and delivery of normally closed clips (i.e. shape memory). The device may accommodate a plurality of clips which include, but are not limited to: malleable metals, absorbable, shape memory, drug-eluting, and adhesive dispensing. The clips may be pigmented to match the colors of associated tissue (cornea, iris, conjunctiva, sclera, retina) to serve to camouflage fixation clips for healing duration or permanently. According to one aspect, shallow angle access to anatomy may be provided by specialized angulation of device shaft and closure jaws that are intended to access the eye through a small self-healing cornea incision and/or any ocular tissue. | 01-03-2013 |
20130168432 | Fasteners, Deployment Systems, and Methods for Ophthalmic Tissue Closure and Fixation of Ophthalmic Prostheses and Other Uses - Improved tissue fasteners are disclosed that can be inserted into (and optionally through) tissue structures underlying a tissue surface, for affixing overlapping tissues and tissue planes together, and the like. In some embodiments, an elongate anvil body may protrude distally and/or laterally from a fastener support disposed along the base. The anvil body may have a sharpened end and be configured to penetrate into the tissue, with the elongate anvil body optionally having a bend from a more distal orientation adjacent the clip support to a more lateral orientation adjacent the sharpened end during at least a portion of the deployment. The first leg can be driven through a desired location on the surface of the first tissue and against a receptacle of the anvil body so as to deform the fastener and affix it to the first tissue. | 07-04-2013 |

20130275102 | COMPUTER SIMULATION OF ELECTROMAGNETIC FIELDS - A method and system is provided for solving for electromagnetic fields by approximating an electromagnetic function as a sum of basis functions multiplied by coefficients to be determined. The set of equations used to determine the coefficients results from taking derivatives of the action integral with respect to the coefficients (and/or other parameters) and setting the derivative equal to zero, thereby extremizing the action integral. | 10-17-2013 |
