SYSTEM FOR NONINVASIVE MEASUREMENT OF AN ANALYTE IN A VEHICLE DRIVER
First Claim
1. A system for non-invasively measuring an analyte in a vehicle driver and controlling a vehicle based on a measurement of the analyte, the system comprising:
- at least one solid-state light source configured to emit different wavelengths of light;
a sample device configured to introduce the light emitted by the at least one solid-state light source into tissue of the vehicle driver;
one or more optical detectors configured to detect a portion of the light that is not absorbed by the tissue of the vehicle driver;
a controller configured to calculate a measurement of the analyte in the tissue of the vehicle driver based on the light detected by the one or more optical detectors, determine whether the measurement of the analyte in the tissue of the vehicle driver exceeds a pre-determined value, and provide a signal to a device configured to control the vehicle.

Abstract
A system for non-invasively measuring an analyte in a vehicle driver and controlling a vehicle based on a measurement of the analyte. At least one solid-state light source is configured to emit different wavelengths of light. A sample device is configured to introduce the light emitted by the at least one solid-state light source into tissue of the vehicle driver. One or more optical detectors are configured to detect a portion of the light that is not absorbed by the tissue of the vehicle driver. A controller is configured to calculate a measurement of the analyte in the tissue of the vehicle driver based on the light detected by the one or more optical detectors, determine whether the measurement of the analyte in the tissue of the vehicle driver exceeds a pre-determined value, and provide a signal to a device configured to control the vehicle.

18. A method for non-invasively measuring an analyte in a vehicle driver and controlling a vehicle based on a measurement of the analyte, the method comprising:
-
introducing, by a sample device, different wavelengths of light emitted by at least one solid-state light source into tissue of the vehicle driver; detecting, by one or more optical detectors, a portion of the light that is not absorbed by the tissue of the vehicle driver; calculating, by a controller, a measurement of the analyte in the tissue of the vehicle driver based on the light detected by the one or more optical detectors; determining, by the controller, whether the measurement of the analyte in the tissue of the vehicle driver exceeds a pre-determined value; and controlling the vehicle based on the measurement of the analyte in the tissue of the vehicle driver. - View Dependent Claims (19, 20, 21, 22, 23, 24, 25)
