Vehicle fatigue monitoring system
First Claim
1. A method for detecting occurrence a fatigue condition of an operator of a driving apparatus, the method being implemented in a processor configured to execute machine-readable instructions, the method comprising:
- receiving a signal indicating a physiological condition of the operator;
determining the physiological condition of the operator is below a threshold;
in response to determining the physiological condition of the operator is below the threshold, obtaining head movement information regarding a movement of the operator'"'"'s head within a time window, wherein the time window specifies an amount of seconds immediately prior to the determination that the operator'"'"'s physiological condition is below the threshold;
determining the head movement information indicates that operator'"'"'s head is moving downwards within the time window; and
in response to the head movement information indicating the operator'"'"'s head is moving downwards within the time window and further to the physiological condition of the operator is below the threshold, generating a signal indicating a fatigue condition is detected for the operator.

Abstract
Embodiments can provide a real-time fatigue monitoring system for detecting and/or monitoring a fatigue condition of a driver of a driving apparatus. In some embodiments, the fatigue monitoring system can include a set of one or more sensors for detecting a physiological condition of the driver, a head movement detection device, one or more processing devices, and/or any other components. In some embodiments, the fatigue condition detection system may include a processing device configured to determine occurrence of a fatigue condition in response to the detection of a physiological condition of the driver is below a threshold while the driver'"'"'s head movement is tilting downwards.

9. A system for detecting occurrence a fatigue condition of an operator of a driving apparatus, the system comprising one or more processors configured to execute machine-readable instructions, wherein when the machine-readable instructions are executed, the one or more processors are caused to perform:
-
receiving a signal indicating a physiological condition of the operator; determining the physiological condition of the operator is below a threshold; in response to determining the physiological condition of the operator is below the threshold, obtaining head movement information regarding a movement of the operator'"'"'s head within a time window, wherein the time window specifies an amount of seconds immediately prior to the determination that the operator'"'"'s physiological condition is below the threshold; determining the head movement information indicates that operator'"'"'s head is moving downwards within the time window; and in response to the head movement information indicating the operator'"'"'s head is moving downwards within the time window and further to the physiological condition of the operator is below the threshold, generating a signal indicating a fatigue condition is detected for the operator. - View Dependent Claims (10, 11, 12, 13, 14, 15, 16)
