摘要： 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.

摘要： A controller retrieves from memory a series of discrete end effector positions consisting of location and orientation of the end effector. Joint angle values are computed in real time corresponding to intermediate points along the path in a manner which provides smooth end effector motion, avoids the problems of singularities and efficiently accommodates kinematic redundancy. In particular, end effector reorientation between successive goal points is smoothly accomplished by rotating the end effector about the eigenvector of the two successive end effector orientations.

摘要： 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.
