System and method for mental impairment determination using reaction time test
First Claim
1. A temporary mental impairment determination system comprising:
- a. a device generating an aural stimulus in the form of a question to be heard by a subject;
b. the device having means to receive aural response to the stimulus from the subject;
c. a measurement means to measure aural response to determine mental impairment of the subject for the ability to safely operate machinery.

Abstract
This invention discloses a satellite based Driver Mentally Impaired (DMI) determination system for auto safety that automatically enables, (i) at the time of auto ignition by driver, the vehicle to be identified at ground station in a Driver mentally impaired (DMI) database and to activate the functions of DMI safety function, (ii) the driver to be identified via voice sample, (iii) the driver profile to be identified in the DMI database, including the time slots when the driver might be drunk, such as evening time and not morning time, (iv) a reaction time test to be conducted, which measures the reaction time responses to simple questions, (v) determine the driver'"'"'s ability to drive, based on driver specific and generic reaction time profiles and (vi) permit the ignition to proceed or not, (vii) If the ignition is denied, it can be done again after a fixed time and/or a designated person and telephone number is automatically dialed and the safety situation to include driver name, vehicle location, time and degree of impairment is conveyed to.

3. The claim as in 2, further comprising:
a system for temporarily preventing drivers, mentally impaired from drugs and alcohol ingested impairment, from driving a vehicle having a mental impairment safety system that administers a reaction time test on attempted vehicle ignition and measures reaction time of driver by comparing responses to voice delivered questions.
-
4. The claim as in 3, further comprising:
-
comparing the measured reaction times to prior stored thresholds and determining to complete ignition based on the results of the comparison.

5. A system for temporarily preventing drivers, mentally impaired from drugs and alcohol ingested impairment, from driving a vehicle comprising:
-
a. a prior art auto safety system using satellite control that remotely controls via a ground station a vehicle'"'"'s operation to include vehicle ignition, and establishes voice communication with the driver;
b. a mental impairment safety function in the ground station that detects mental impairment of a driver and disables vehicle ignition if the driver is mentally impaired. - View Dependent Claims (6, 7, 8, 9, 10, 11)
