摘要:
A number of ear-worn hearing system devices are provided that each include a pair of electrodes to transmit time varying electrical signals therebetween when in contact with skin of a user's body. The devices each include a housing, a sound sensor, and processing circuitry included within the housing. The electrodes are coupled to the circuitry and are spaced apart from one another a distance sufficient to provide capacitance between the electrodes below a desired threshold. The electrodes are disposed along the housing for placement on locations of the user's body where skin contact is not likely to be disrupted by nominal body movements.
摘要:
A method of detecting cardiac arrhythmia in a patient is described. This method involves determining whether there is a mutation in the nucleotide sequence, the amino acid sequence, or both, of connexin40 obtained from a patient. The mutation may be localized within the transmembrane domain of connexin40. Furthermore, there is described a method of identifying a compound for the treatment of cardiac arrhythmia. This method involves providing a cell culture that is characterized by having impaired intracellular trafficking, impaired electrical coupling, reduced gap junction plaque formation, reduced intracellular coupling, or a combination thereof, when compared to a wild-type cell. A compound is added to the cell culture, and restoration of intracellular trafficking, electrical coupling, gap junction plaque formation, intracellular coupling, or a combination thereof, is monitored.

摘要:
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.
