Binaural signal processing using multiple acoustic sensors and digital filtering
InactiveUS6978159B2Easy extractionExtensive computationTwo-way loud-speaking telephone systemsSubstation equipmentFrequency spectrumSound sources
A desired acoustic signal is extracted from a noisy environment by generating a signal representative of the desired signal with processor (30). Processor (30) receives aural signals from two sensors (22, 24) each at a different location. The two inputs to processor (30) are converted from analog to digital format and then submitted to a discrete Fourier transform process to generate discrete spectral signal representations. The spectral signals are delayed to provide a number of intermediate signals, each corresponding to a different spatial location relative to the two sensors. Locations of the noise source and the desired source, and the spectral content of the desired signal are determined from the intermediate signal corresponding to the noise source locations. Inverse transformation of the selected intermediate signal followed by digital to analog conversion provides an output signal representative of the desired signal with output device (90). Techniques to localize multiple acoustic sources are also disclosed. Further, a technique to enhance noise reduction from multiple sources based on two-sensor reception is described.

Magnetic pulsing system for inducing electric currents in a human body
ActiveUS20070142886A1Convenient treatmentElectrotherapyMagnetotherapy using coils/electromagnetsHuman bodyDisease
Disclosed is a means and method for the treatment of migraine headaches and other disorders of the human body by the application of one or more intense magnetic pulses. By placing an intense magnetic field pulse(s) onto a certain region of the brain, an electrical current can be generated in the cerebral cortex that can stop a migraine headache in some patients or at least decrease its severity. The device to perform this function can be called a “magnetic pulser system.” This system can be made in one piece and powered by plugging into a household or automobile receptacle or from a battery. The pulser system uses capacitors that are first charged to a high voltage and then discharged into a coil that creates the intense magnetic pulse. Both visual and auditory signals can be provided by the pulser system to assist the patient in using the device.
