Abstract: A modular electrical safety assembly for use with a control device of an electrical equipment includes a magnet housing with a magnet, an equipment cover, and a slider. The magnet housing includes a magnet to selectively couple to the electrical equipment. The magnet induces an attraction force on the electrical equipment. The equipment cover is coupled to the magnet housing and configured to prevent operation of the control device. The slider is configured to translate along a surface of the equipment cover between a first position and a second position. In the first position it prevents a change in polarity of the magnet. In the second position it permits a change in polarity of the magnet. The slider and equipment cover lock together to selectively restrict translation of the slider.

Abstract: Disclosed herein is a drive unit for driving a tool mated with a tool receptacle in a device. The drive unit includes a tool carrying apparatus configured to carry the tool, and a proximity sensor cooperating with at least a portion of the tool carrying apparatus so as to detect movement of the tool carrying apparatus along a longitudinal axis thereof. A motor apparatus is configured to rotate the tool carrying apparatus. Control circuitry is configured to operate the motor in an engagement mode to rotate at least a portion of the tool carrying apparatus until the tool is rotationally aligned with the tool receptacle so as to permit insertion thereinto, based on the proximity sensor not detecting movement of the tool carrying apparatus a threshold distance along the longitudinal axis toward the tool receptacle.
