Abstract
This invention provides a sleepy alarm apparatus for a vehicle driver, which is activated by a heart pulse meter, of which the measured heart pulse rate is lower than the preset threshold sleepy pulse rate. When a driver is sleepy while driving, the pulse rate is gradually decreasing. This invention continuously monitors the time interval for the predetermined number of the driver's pulses and converts the time interval into a pulse rate. If the measured pulse rate is lower than the preset threshold pulse rate, the system will trigger an alarm unit, which is a part of the present invention. The preset threshold pulse rate can be adjusted by the increase or decrease switch. The apparatus may be made to be wearable on a wrist or made to be attachable on the steering wheel of the vehicle being driven. In which case, the device includes a cuff for placing a finger in it in order to monitor the heart pulses.
