Walter M Weber, Ammar Al Ali, Lorenzo Cazzoli: Signal component processor. Masimo Laboratories, Knobbe Martens Olson & Bear, February 1, 2005: US06850787 (485 worldwide citation)

A signal processor generates basis functions and identifies at least one basis function component of a sensor signal in order to calculate a physiological measurement. The signal processor is advantageously applied to pulse oximetry so as to directly calculate oxygen saturation and so as to calculat ...
