Patent ID: 8805465

Claim:
A sensor comprising: a single sensor body having a first surface configured to contact a patient when applied to the patient, comprising: a first sensor subsystem disposed on the first surface of the sensor body, comprising: a first emitter configured to emit light at one or more wavelengths; a first detector configured to detect light at the one or more wavelengths; a second sensor subsystem disposed on the first surface of the sensor body, comprising: a second emitter configured to emit light at one or more wavelengths; a second detector configured to detect light at the one or more wavelengths; and an isolating portion separating the first sensor subsystem from the second sensor subsystem, wherein the isolating portion is disposed between the first sensor subsystem and the second sensor subsystem and forms a portion of the first surface of the sensor body and is configured to functionally isolate the first sensor subsystem from the second sensor subsystem when the first sensor subsystem and the second sensor subsystem are positioned on a common measurement surface.
