Latest Patents
One of his latest patents is titled "Apparatus and method for concealing data bursts in an analog scrambler using audio repetition." This invention provides a method for concealing data bursts in an analog scrambler by substituting parts of the audio signal for the data bursts. The periodic data bursts that would typically appear at the audio output are replaced with selected audio portions from the multiplexed signal. This technique effectively conceals the data bursts, thereby improving the audio quality that would otherwise be degraded by the periodic mixing of data bursts with the audio portions.
Another notable patent is "Apparatus and method for maintaining a constant speech envelope using variable coefficient automatic gain control." This invention monitors the level of the audio signal and applies different levels of gain adjustments based on whether the signal is increasing or decreasing. By applying a lower level of change when the signal is decreasing, a more consistent speech envelope is achieved during common gaps in speech, enhancing the overall audio experience.
