1. A computerized method for ensuring that an operator remains alert during operation of a train comprising the steps of:
- (a) monitoring at least one train control device to determine whether the operator is operating the train control device;
(b) if the operator has not operated the train control device within a first time period, displaying at least one sequence to an operator on a display device;
(c) determining whether the operator has entered a corresponding sequence within a second time period; and
(d) stopping the train if the operator fails to enter the corresponding sequence within the second time period.

Abstract
A system and method for ensuring that an operator remain alert includes monitoring the operator to determine when the operator is actively working the train controls, and, when the operator has not actively worked the controls for a first period of time, displaying a sequence the repetition of which requires cognitive alertness of the operator. If the operator fails to repeat the sequence, or a corresponding sequence, the train is stopped. In some embodiments, the cognitive alerter is inoperative below predetermined speed levels.

10. A system for ensuring that an operator remains alert during operation of a train, the system comprising:
-
a processor; at least one sensor connected to the processor; a display connected to the processor; an input device connected to the processor; and a brake interface connected to the processor; wherein the processor is configured to perform the steps of (a) monitoring the at least one sensor to determine whether the operator is operating the train control device; (b) if the operator has not operated the train control device within a first time period, displaying at least one sequence to an operator on the display, (c) determining whether the operator has entered on the input device a corresponding sequence within a second time period; and (d) commanding the brake interface to stop the train if the operator fails to enter the corresponding sequence within the second time period. - View Dependent Claims (11, 12, 13, 14, 15, 16, 17, 18)
