  • Patent number: 7225027
    Abstract: A method of improving sound quality of audio signals that are digitally processed includes steps of extracting amplitude and frequency modulations from one or more narrow bands of the audio signal, and filtering and compressing those modulations to produce amplitude and frequency modulated audio signals that are digitally processed to provide an acoustic signal similar to the original audio signal. The methods may be used in auditory prostheses and telecommunication systems.

  • Patent number: 7158831
    Abstract: A cardiac pacemaker in which a variable safety margin with respect to a capture threshold is employed in delivering pacing pulses. The safety margin of a pacing pulse is made to vary in accordance with the pattern of preceding intrinsic and paced beats. The pacing pulse energy is thereby maintained at a more optimum value with respect to the capture threshold.
