Multiple wavelength sensor drivers
Abstract:
A physiological sensor has light sources arranged in one or more rows and one or more columns. Each light source is activated by addressing at least one row and at least one column. The light sources are capable of transmitting light of multiple wavelengths and a detector is responsive to the transmitted light after attenuation by body tissue.
