Claim 15:
16. A pulse oximeter article for reducing melanin bias and measuring blood oxygen saturation, comprising:
a plurality of light sources comprising:
a first light source configured to emit light at a first wavelength selected for absorption by oxyhemoglobin, and
a second light source configured to emit light at a second wavelength, different from the first wavelength, selected for absorption by deoxyhemoglobin;
a detector configured to:
detect light emitted by the first light source or the second light source,
convert light detected from the first light source into a first current signal, and
convert light detected from the second light source into a second current signal,
at least one voltage converter configured to convert the first current signal into a first voltage signal and the second current signal into a second voltage signal,
a communication interface configured to communicate information associated with the first voltage signal or the second voltage signal over a communication network, and
one or more processors in communication with the at least one voltage converter and the communication interface,
wherein the first wavelength and the second wavelength are selected to reduce the melanin bias, and
wherein blood oxygen saturation measurements are determined by the one or more processors based on the first voltage signal and the second voltage signal received from the at least one voltage converter.
