  • Patent number: 7810753
    Abstract: Helical winding is reliably carried out in a plurality of patterns at different angles in a short period of time. A filament winding apparatus for winding fiber bundles onto the surface of a mandrel includes a helical winding head for use in helical winding of the fiber bundles onto the mandrel. The helical winding head includes at least two guide arrays, each including a plurality of guide portions disposed along a circumferential direction of the mandrel, and a repositioning mechanism capable of repositioning the guide portions by rotating each guide array relative to another.

  • Patent number: 6912323
    Abstract: A fast convolution method applicable to convolving a signal (indicative of an n-dimensional pattern, where n is greater than or equal to two) with a smooth kernel that can be approximated by a separated-spline kernel, and a system configured to perform such method using software or signal processing circuitry. Unlike Fourier-based convolution methods which require on the order of N log N arithmetic operations for a signal of length N, the method of the invention requires only on the order of N arithmetic operations to do so. Unlike wavelet-based convolution approximations (which typically also require more arithmetic operations than are required in accordance with the invention to convolve the same signal), the method of the invention is exact for convolution kernels which are spline kernels.

  • Patent number: 6701028

Unlike Fourier-based convolution methods which require on the order of N log N arithmetic operations for a signal of length N, the method of the invention requires only on the order of N arithmetic operations to do so. Unlike wavelet-based convolution approximations (which typically also require more arithmetic operations than are required in accordance with the invention to convolve the same signal), the method of the invention is exact for convolution kernels which are spline kernels. Moreover, convolution in accordance with the invention can be acyclic convolution (achieved without zero-padding) or cyclic convolution, and in both cases the invention imposes no restriction (such as evenness) on signal length.

  • Patent number: 5749537
    Abstract: A method of wrapping cryogenic insulation around an inner tank disposable within an outer tank of a cryogenic tank system, where cryogenic insulation paper is unrolled from a roll thereof, wrapping the paper in serially disposed wraps around the inner tank, unrolling cryogenic insulating metal foil from a roll thereof and wrapping the foil in serially disposed wraps onto respective serial wraps of the paper. In the method there is utilized at least one combined roll of cryogenic insulation having alternating combined layers of the paper of a defined first width and foil of a defined second width wherein the defined second width is less than the defined first width and the foil is centered on the paper so as to provide edge portions at each edge of the paper which are not contacted by the foil. Lengths of combined layers are unrolled from the combined roll, and the lengths of combined layers are serially wrapped around the inner tank.
