SLEEP DELAY APPARATUS FOR DRIVERS
First Claim
1. An apparatus to delay drowsiness and sleep for drivers and others comprised of:
- one or more thermoelectric modules mounted on a variety of mounting structures touching sensitive locations on the user'"'"'s body;
a control unit to supply said modules with pulsed drive signal defining module on and off times;
a means of coupling the sequenced pulse drive signals from the control unit to the thermoelectric modules;
means of starting the sequence of drive pulses to the thermoelectric modules.

Abstract
This invention relates to an apparatus to aid drivers by delaying the onset of drowsiness and its tendency toward slow response time and brief periods of micro sleep. The preferred embodiment uses two thermoelectric modules mounted on a belt and positioned under the armpits. The modules are most effective when placed in contact with the skin but still effective if placed over light clothing. Manual activation of the unit is preferred but it has input for optional head tilt sensor or eyelid closure sensor. It quietly alarms by sequentially cooling one of the thermoelectric modules while the other thermoelectric module is warmed slightly above body temperature. The sequential pulse driving cycle is controlled by a remote timer located in a small enclosure which is powered from a cigarette lighter plug. The drive signal duration and thus the level of alarm is controlled with a multi-position control on the enclosure.
