ABSTRACT:
An alerting device generates a variable alert that is varied to indicate the amount of time that has elapsed since the alert began. The alerting device has an alert signal detector, a timing unit, an alert signal generator and an alert unit. The alert signal detector responds to an activation signal to activate the timing unit, and the alert signal detector responds to a deactivation signal to reset the timing unit. The timing unit generates timing information to the alert signal generator indicating the elapsed time since the occurrence of the activation signal. The alert signal generator responds to the activation signal and to the timing information to generate an alert signal that indicates the elapsed time since the occurrence of the activation signal. The alert signal generator further responds to the deactivation signal to disable the alert signal. The alert unit responds to the alert signal to generate an alert that reflects the elapsed time since the occurrence of the activation signal.
