Latest Patents

One of Nuttall's latest patents is the "Bio-acoustic wave energy transducer." This invention presents a method and apparatus that addresses the 'Curse of Dimensionality' (COD) in characterizing nonlinear physical systems. It reduces the number of coefficients needed to describe higher-order kernels in the Volterra series expansion. This technique allows for the simultaneous evaluation of inter-modulation products from a wide band excitation, simplifying the manipulation of data by current personal computers. This innovation enhances finite element models that generate bio-inspired acoustic transducer models.

Another significant patent is the "Method and apparatus for improved active sonar using singular value decomposition filtering." This invention utilizes singular value decomposition filtering and a Volterra-Hermite Basis Expansion to model real active sonar measurements. The model minimizes the squared errors between measured and model responses, requiring an excitation waveform as input. A contracted broadband cross-ambiguity function corrects the excitation waveform for Doppler and range effects, allowing for a better understanding of channel effects.
