Personal monitoring and alerting device for drowsiness
First Claim
1. A method of monitoring and analyzing the electro-physiological variables of peripheral pulse rate variability, peripheral vasomtor response, muscle tone, and peripheral blood flow for identifying increasing drowsiness and creating alert flags raised by each and every parameter violating a preset ratio of trended value divided by its baseline;
- said method comprising the steps of providing a first parameter alert flag for identifying the violation of peripheral pulse rate variability preset;
providing a second parameter alert flag for identifying the violation of peripheral vasomotor response preset;
providing a third parameter alert flag that identifies the violation of muscle tone preset;
providing a fourth parameter alert flag that identifies the violation of peripheral blood flow presets;
providing a fifth parameter alert flag that identifies the violation of reaction time variability preset; and
generating an overall alert flag upon a majority of parameter flags being raised.

Abstract
A wrist worn device and method for monitoring and alerting the user of increased drowsiness. The device includes sensors for monitoring several physiological parameters of the user, including peripheral pulse rate variability, peripheral vasomotor response, muscle tone, peripheral blood flow and reaction time variability. If the majority of these parameters are indicative of increased drowsiness, and audio-visual alert is provided the user. The sensors are encased in a shock-absorbing unit and wirelessly transmit the sensed data.
