Apparatus and method for controlling operation of vehicles or machinery by intoxicated or impaired individuals
First Claim
1. A method of controlling the operation of equipment, comprising:
- a) Collecting spectral information representative of the interaction of a subject'"'"'s tissue with incident radiation;
b) Determining from the spectral information as collected in step a) an analyte property;
c) Determining from the spectral information as collected in step a) an identity characteristic;
d) Determining an equipment operation parameter from the analyte property and the identity characteristic;
e) Controlling the operation of the equipment according to the equipment operation parameter.

Abstract
The present invention relates generally to non-invasive methods and apparatuses for determining analyte properties of a subject and identity characteristics of a subject. Embodiments of the present invention provide analyte property determination and identity determination or verification from the same spectroscopic information, making unauthorized use or misleading results less likely that in systems that include separate analyte and identity determinations. The invention can be used to prevent operation of automobiles or other equipment unless the operator has an acceptable alcohol concentration, and to limit operation of automobiles or other equipment to authorized individuals who are not intoxicated or drug-impaired.

43. An apparatus to control operation of a vehicle, comprising:
-
a) An illumination system, providing radiation at one or more wavelengths; b) A sampling system, receiving radiation from the illumination system and communicating radiation to tissue of a subject; c) A spectrometer system, receiving radiation from the tissue after interaction of the tissue with radiation from the sampling system and generating a signal representative of the tissue'"'"'s interaction with radiation; d) A data acquisition system, generating spectroscopic data responsive to the signal from the spectrometer system; e) An analysis system, determining an analyte property of the tissue responsive to the spectroscopic data and an identity characteristic of the subject responsive to the same spectroscopic data from the data acquisition system; and f) An interlock system, controlling operation of the vehicle responsive to the analyte property and the identity characteristic. - View Dependent Claims (44, 45, 46, 47)
