ABSTRACT:
A fatigue alarm comprising a housing, with the housing including a first fixed handle plate extending from the housing and a second movable handle plate separated from the first handle plate in a biased separation relative to one another, such that a first electrical contact secured to the second handle plate within the housing is in contiguous communication with a second electrical contact within the housing in a normal configuration, such that upon separation of the first electrical contact relative to the second electrical contact against a spreader member within the housing effects disengagement and de-actuation of an audible alarm, whereupon fatigue permits movement of the second handle plate away from the first handle plate to engage the first electrical contact and the second electrical contact to actuate the audible alarm to alert an individual relative to onset of sleep.
