ABSTRACT:
A method for assuring a safe work space operates so that a work enable signal is generated only when absence of workers from the work space where the workers work in cooperation with a machine is detected. The work enable signal has a logical value of 1 corresponding to a high energy state and only this signal can initiate activation of the machine sharing the subject work space thereby assuring safe environments for workers.
