Title: The Innovations of Patrick M. Peterson
Introduction
Patrick M. Peterson is a notable inventor based in Cambridge, MA (US). He has made significant contributions to the field of technology, particularly in audio signal processing and noise reduction. With a total of 2 patents, his work has had a lasting impact on various applications.
Latest Patents
One of his latest patents is titled "Embedded Signalling." This invention involves generating a code signal that represents a sequence of code symbols carrying digital information. The frequency components of the code signal are confined to a preselected signalling band within the bandwidth of an audio signal. The audio signal is continuously analyzed, and the code signal is dynamically filtered to create a modified code signal. This modified signal can be combined with the audio signal to produce a composite audio signal that is not easily distinguishable from the original. The digital information can then be recovered from this composite audio signal using a complementary procedure.
Another significant patent is "Adaptive Beamforming for Noise Reduction." This invention addresses challenges faced in conventional noise cancelling circuitry, particularly when the signal-to-noise ratio at the sensor array is high. The adaptive noise cancelling apparatus selectively inhibits the adaptive filter from changing its filter values in such instances, preventing the generation of a noise-approximating signal that could degrade the target component of the output signal.
