Patent ID: 8549318

Claim:
A system for preventing use of a vehicle by an operator of the vehicle, the system comprising: a system controller; a biometric authenticator coupled to the system controller; and a separate analyte detecting device adapted to provide an analyte level in the operator to the system controller, wherein the system controller is adapted to communicate a driving restriction to the vehicle if the analyte level in the operator is above a tolerance level or if the operator is not authenticated by the authenticator, wherein the analyte level is determined at a first dermal location on the hand of the operator, wherein the operator is authenticated at a second, separate dermal location of the operator proximate to the first dermal location at a time substantially simultaneous with the analyte level determination, wherein the second, separate dermal location is selected from the group of dermal locations on the operator consisting of finger, thumb, and palm, wherein the authenticator comprises a biometric authenticator selected from the group consisting of a fingerprint authenticator, a hand-geometry authenticator, and combinations thereof, and wherein the analyte detecting device further comprises a light source configured to direct a light beam at a specific wavelength band within a range from 1300 nm to 2400 nm toward the first dermal location for reflectance to a broadband detector.
