  • Patent number: 6411106
    Abstract: This invention provides a method and apparatus for the sensing of moisture using microwave technology. The apparatus provides a wave guide having a linear array of slots in its broadwall. A detector detects reflected energy of microwave signals over a frequency range once the material is positioned over the slots. A value indicative of the power spectral density of the reflected signals is computed and a value for the moisture content of the material determined from the value of power spectral density. The slots are at an angle with respect to the longitudinal axis of the wave guide and the angle can be varied according to the material being tested.

  • Patent number: 6399011
    Abstract: A method of inducing biaxial particle alignment in a body of crystalline particles of a material such as a high temperature superconducting material, having anisotropic magnetic susceptibility so that at least a major portion of the crystalline particles have at least two crystalline axes generally parallel, comprises subjecting the particles to a magnetic field which varies cyclically relative to the body of crystalline particles with time, and which has an average magnitude which is a maximum in a first direction, a lower average magnitude in a second direction generally orthogonal to said first direction and a minimum or zero average magnitude in a third direction generally orthogonal to said first and second directions. Alignment of the axis of maximum magnetic susceptibility of the particles generally with the direction of maximum average magnitude and the axis of minimum magnetic susceptibility of the particles generally with the minimum or zero average magnitude direction is induced.

  • Patent number: RE39189
    Abstract: A multi-channel reverberation system has a substantially constant multi-channel power gain at audio frequencies and comprises multiple signal inputs, one for each input channel, a number of comb filter networks connected to each signal input, each comb filter network including a feed forward stage, a cross-coupling network cross-coupling the comb filters to increase the reverberation echo density, and multiple signal outputs, one for each output channel. Preferably the feed forward stage of each comb filter provides a substantially constant multi-channel power gain at audio frequencies and the cross-coupling matrix is an orthogonal cross-coupling matrix cross-coupling a number of single channel allpass comb filters, positioned immediately before or after the delay lines, to create a multi-channel allpass comb filter with a unitary transfer function matrix at all frequencies.
