Benefits of technology

[0006]In accordance with the present invention, a method and apparatus are provided for precise spectroscopic detection of a substance present in the blood of a person, such as alcohol or its metabolic byproducts, preferably in conjunction with a biometric verification of that person. In accordance with one aspect of the present invention, the spectroscopic detection may be accomplished by impinging electromagnetic radiation on the tissue of a person and acquiring and analyzing electromagnetic radiation resulting from the inte

Problems solved by technology

In addition, the system may be used to prevent operation of the vehicle, machinery, or heavy equipment if the biometric authentication does not verify the person whose blood alcohol concentration is detected as a person authorized to operate the vehicle, machinery, or heavy equipment.

Embodiment Construction

[0034]FIG. 1 is a diagram of a housing 10 that contains a probe head 40, probe base 30, and biometric sensor 20 according to an exemplary embodiment of the present invention. The biometric sensor 20 is positioned to obtain unique information to identify a person in conjunction with detection of the blood alcohol concentration of the person. Verification of the person is preferably determined before or contemporaneously with the detection procedure that is performed at a predetermined sampling region of the person. The probe head 40 is configured within a housing 10 to assure that spectroscopic detection of the person is performed reliably.

[0035]The sampling region may be the interstitial region between fingers, and preferably is the interstitial region between the index and middle fingers of a hand of the person. Alternatively, the sampling region may be between the toes of the person. In addition, the region adjacent to a single finger or toe may serve as the sampling region. The s...

Abstract

An apparatus and method for acquiring and analyzing a spectroscopic sample for a substance from a sampling region of the tissue of a person at an interstitial region between the fingers of the person, by way of a probe and a spectroscopic detector for radiating the interstitial region with electromagnetic radiation and analyzing a diffuse-reflectance signal obtained from the tissue at the sampling region. The apparatus preferably also incorporates a biometric sensor to perform a verification of the person.
