First Claim
1. A system for monitoring fatigue and notifying a user, the system comprising:
- a wearable apparatus comprising;
a sensor configured to measure biomarkers of the user;
a communication module; and
a support configured to support the sensor; and
a remote device comprising;
memory;
a notification generator configured to generate a warning to the user via the communication module in response to receipt of a signal;
a processor communicatively coupled to the sensor and the notification generator, the processor configured to;
obtain, from the communication module, biomarker measurements from the sensor;
generate a personal circadian rhythm for the user, and a position of the user along that circadian rhythm, using the measured biomarkers;
identify a baseline risk level for the user by assessing the personal circadian rhythm of the user and the position of the user along that personal circadian rhythm;
determine a sleep drive of the user based upon continual or periodic sensor measurements, wherein sleep and wakefulness cycles of the user are derived from actigraphy data obtained from the sensor; and
send the signal to the notification generator when the baseline risk level is in a predetermined range.

Abstract
Methods and apparatus for monitoring fatigue and notifying an individual are described. The individual may be an operator of a vehicle, equipment, or machine, a student, or other person that may experience fatigue. Motion of the individual is monitored to detect a predescribed motion in response to a stimulus to first determine a base responsiveness profile. Afterwards, a current responsiveness profile is determined based on a prescribed motion in response to a stimulus, and if the current responsiveness profile exceeds a predetermined threshold of the base responsiveness profile, a notification is issued to the individual and, optionally, another person such as an employer, teacher, or parent.
