    Abstract: A welding helmet (1) has a protective shield (2) and a first swivel mechanism (10) that pivotally connects the protective shield with a head suspension system (6) for swiveling about a swivel axis. The first swivel mechanism enables the protective shield and the head suspension system to be swiveled between a lowered position, in which the protective shield covers a wearer's face, and an upraised position, in which the protective shield uncovers the wearer's face. The first swivel mechanism (10) has a recess (16a) and a retainer (17a) for engaging with the recess. The retainer and the recess are arranged to engage with each other in the upraised position, and to remain disengaged in the lowered position and between the lowered position and the upraised position.

    Abstract: A tool communication adapter system is provided. One exemplary system described herein includes a tool communication adapter having an adapter body including first and second mechanical attachment ends, a first electrical connector proximate the first mechanical attachment end and a second electrical connector proximate the second mechanical attachment end, a first supply channel having an opening extending through the body between the first and second mechanical attachment ends, and including a first supply channel connector at the first attachment end and a second supply channel connector at the second mechanical attachment end, and a control unit in communication with the first and second electrical connectors. The control unit is configured to provide a filter command signal to a protective filter in response to a signal received at the first electrical connector. An exemplary tool communication adapter thus allows communication between a tool and personal protective equipment.

    Abstract: A powered air purifying respirator (PAPR) with an active heating system. The PAPR includes a powered air component designed to be carried by a user of the PAPR, the powered air component including a fan and a filter, wherein the fan draws air from a user's environment through the filter. The PAPR further includes an electronically controlled active heating element and a control system. The control system varies the power provided to the heating element and further disables the heating element when potential overheating of the heating element is detected. The present invention further includes a heating module for use with a PAPR. The heating module includes an electronically controlled active heating element. The heating element is disabled when the fan in the PAPR is not rotating.
