Patent ID: 8078334

Claim:
An unobtrusive system for monitoring the physiological condition of a target user of a vehicle comprising: a wearable device affixed to the target user; a measurement subsystem releasably coupled to the wearable device configured to measure a concentration of at least one analyte in the blood of the target user at one or more time increments; wherein at least one analyte includes an analyte chosen from the group consisting of: alcohol, drugs, glucose, proteins, enzymes, hormones, glucose ethanol, insulin, water, carbon dioxide, blood oxygen, cholesterol, bilirubin, ketones, fatty acids, lipoproteins, albumin, urea, creatinine, white blood cells, red blood cells, hemoglobin, oxygenated hemoglobin, carboxyhemoglobin, organic molecules, inorganic molecules, pharmaceuticals, narcotics, tetrahydrocannabinol, cytochrome, various proteins and chromophores, microcalcifications, electrolytes, sodium, potassium, chloride, bicarbonate, and hormones; a proximity sensor configured to detect the location of the wearable device; and a vehicle control subsystem responsive to the proximity sensor and the measurement subsystem configured to determine if the wearable device is proximate a predetermined location in the vehicle and configured to determine if the measured concentration of the at least one analyte exceeds a predetermined threshold concentration level, and based on such a determination, initiate one or more predetermined actions.
