Latest Patents

Okamoto's latest patents include an innovative oscillator and oscillator adjustment method with stepwise delay. This invention features a delay coarse adjustment circuit, a delay fine adjustment circuit, and an inverter circuit. The delay coarse adjustment circuit stepwise varies a delay amount based on the delay coarse adjustment signal and supplies the input oscillation signal with a coarse delay. The delay fine adjustment circuit, on the other hand, provides a finer delay that is smaller than the coarse delay. Together, these circuits allow for precise control of the oscillation output signal. Another notable patent is a digital audio signal processing apparatus and method for error correction. This method determines an interpolated value for an audio data error sample, effectively concealing errors in audio data samples by utilizing a Lagrange polynomial equation.
