Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A physiological sensor comprising: a plurality of light emitters comprising at least a first light emitter and a second light emitter; an electrical grid configured to activate one or more light emitters of the plurality of light emitters by addressing at least one row conductor and at least one column conductor, wherein each of the one or more light emitters comprises a first terminal and a second terminal; a first contact communicatively coupled with t…
