He holds a total of 2 patents that showcase his expertise in encoding and decoding digital signals, particularly in the realm of audio technology. His innovative approaches have contributed significantly to advancements in signal processing.
Latest Patents
One of Addison's latest patents is titled "Method and apparatus for modeling discrete data sequences by multiple." This invention focuses on a method for encoding and decoding digital signals using multiple reference vectors from a codebook. The process involves adaptively updating the codebook to achieve a synthesized vector that closely matches the digital signal. The encoded signal comprises mathematical combination function coefficients and memory addresses of the reference vectors used. The decoding process separates these coefficients and addresses, employing a reverse combination procedure to reproduce the synthesized vector, which is then stored in the codebook by overwriting the oldest data.
Another significant patent by Addison is "Scrambling of signals by inversion." This invention introduces an inversion scrambler and unscrambler that utilizes pseudo-randomly controlled polarity-reversing switches to invert and re-invert audio signals. This method aims to restrict the intelligent dissemination of audio signals. To enhance security, the audio signal is concealed before scrambling, which includes clamping the original signal to a predetermined value. The scrambling process involves inverting portions of the signal at pseudo-random intervals, controlled by a pseudo-random code generator. Upon unscrambling, artifacts may appear at inversion points, which are masked using track-and-hold circuitry.
