Classification: CPC A  G | IPC A  G

Claim 0:
1. A multi-channel measurement device for measuring properties of human tissue, comprising:
a microcontroller;
a first housing;
a second housing coupled to the first housing in an opposing relationship;
the first housing having a first source/sensor complex including a first light sensor coupled to the microcontroller and a first plurality of light sources coupled to the microcontroller;
the second housing having a second source/sensor complex including a second light sensor coupled to the microcontroller and a second plurality of light sources coupled to the microcontroller;
the first plurality of light sources being angled toward the second light sensor such that a portion of light energy emitted by each of the first plurality of light sources is reflected to the first light sensor and a portion of the emitted light energy is transmitted to the second light sensor by human tissue placed between the first and second housings;
the second plurality of light sources being angled toward the first light sensor such that a portion of light energy emitted by each of the second plurality of light sources is reflected to the second light sensor and a portion of the emitted light energy is transmitted to the first light sensor by human tissue placed between the first and second housings;
the microprocessor being configured with instructions stored in non-volatile memory that, when executed by the microprocessor, cause the microprocessor to individually activate each of the light sources of the first and second pluralities of light sources and to record light intensity detected by the first and second light sensors while an individual light source is activated;
wherein each combination of an individually activated light source and one of the first and second light sensors provides a distinct measurement channel for measuring the absorption spectra of human blood and tissue.
