1. A physiological sensor configured to measure an indication of a physiological characteristic of a living patient, the physiological sensor comprising:

  • a plurality of light emitting sources arranged to impinge light on body tissue of the living patient including at least six light emitting sources, wherein the plurality of light emitting sources emit light of at least three different wavelengths, and wherein at least one of the light emitting sources is activated by addressing a first row of a plurality of rows and a first column of a plurality of columns of an electrical grid;

    at least one information element configured to convey information about the physiological sensor, wherein the at least one information element is activated by addressing a second row of the plurality of rows and a second column of the plurality of columns of the electrical grid;

    a detector responsive to transmitted light after attenuation by body tissue of the living patient, the body tissue including pulsating blood, wherein the detector is configured to generate a signal indicative of a physiological characteristic of the living patient; and

    a sensor housing configured to position the plurality of light emitting sources and the detector with respect to the body tissue of the living patient.
