Latest Patents

One of Stan Sasaki's latest patents is the Multi-state Echo Suppressor. This innovative device utilizes a multi-state operating sequence to provide non-disruptive monitoring of a remotely broadcast program during a performer's live performance at a local site. The system is actuated by a voice-activated switch that initiates signal processing to correlate the locally originating audio, such as the performer's voice, with its echo in the broadcast program. The echo suppressor allows the performer to hear their own voice while preventing echo from being heard until correlation is achieved and echo suppression can begin. The correlation states include an initial correlation at a reduced sampling rate to detect echo within a wide delay time window, followed by a second correlation at a higher sampling rate to refine the echo detection.

Another significant patent by Sasaki is the Volume Adjustment as a Function of Transmission Quality. This invention provides graceful degradation of audio quality as transmission quality decreases by dynamically adjusting the volume of audio output based on the rate of transmission errors. The receiver estimates transmission errors by detecting known information embedded in the audio signal. As transmission errors increase, the receiver attenuates the audio output volume accordingly, applying a smoothing function to avoid disruptive fluctuations in audio output.
