Physiological sensor
First Claim
1. A physiological sensor comprising:
- at least one sensor pad;
at least one light source assembly disposed on said at least one sensor pad and having a plurality of light sources each arranged in anti-parallel pairs;
a plurality of switches in communication with the light source assembly via a plurality of wires, wherein actuating a select combination of the plurality of switches activates at least one of the plurality of light sources and wherein a number of light sources disposed on the sensor pad is greater than a number of wires connecting the plurality of switches to the at least one light source assembly; and
wherein said at least one light source assembly is configured to measure at least one physiological characteristics of body tissue.

Abstract
A sensor used to measure physiological characteristics of body tissues is provided. The physiological sensor includes a first light source assembly having a first light source in parallel with a second light source. Each of the first light source and the second light source have an anode and a cathode. A second light source assembly includes a third light source in parallel with a fourth light source. Each of the third light source and the fourth light source have an anode and a cathode. The anode of the first light source is electrically connected to the cathode of the second light source, the anode of said third light source, and the cathode of said fourth light source. The anode of the third light source is electrically connected to the cathode of the fourth light source.

19. A physiological sensor comprising:
-
a first light source assembly and a second light source assembly, each having two light sources arranged in an anti-parallel pair and electrically connected to a first pair of switches, a second pair of switches, and a third pair of switches via a plurality of wires, wherein no more than three wires connect the first and second light source assemblies to the first and second pairs of switches, wherein one light source in the first light source assembly is configured to activate when one switch from both the first and second pairs of switches are enabled and wherein another light source from the first light source assembly is configured to activate when another switch from both the first and second pairs of switches are enabled.
