Personal protective system tool communication system

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.

What is claimed is: 
     
         1 . A system comprising:
 a welding tool comprising a user input configured to generate a tool activation signal;   a tool power controller configured to provide power to the tool in response to the user input;   a tool connector for connecting the welding tool to the tool power controller such that the tool power controller provides power to the tool in response to activation of the user input;   welding headgear including a body and a shield positioned on the body, the shield having a wide viewing area configured to be positioned in front of a user's eyes during normal use, wherein the shield is configured to protect the user's eyes and face before the tool is activated;   a protective filter movably mounted to the welding headgear configured to be worn by the user, wherein the protective filter is mounted to an attachment location on the headgear and physically moves in relation to the headgear between an open position away from the user's eyes and a closed position to cover the shield and user's eyes in response to a closed filter command signal; and   a control unit in communication with the tool connector;   wherein the control unit is configured to provide the closed filter command signal to the protective filter in response to the tool activation signal, wherein the protective filter communicates a closed return signal when in the closed position.   
     
     
         2 . The system of  claim 1 , wherein the tool power controller is configured to supply power to the tool when the protective filter generates a closed signal. 
     
     
         3 . The system of  claim 1 , wherein the protective filter generates an open return signal when moved to the open position. 
     
     
         4 . The system of  claim 1 , wherein the user input further comprises a tool deactivation signal, and the control unit provides an open command signal to the protective filter in response to the tool deactivation signal. 
     
     
         5 . The system of  claim 1 , wherein the control unit comprises a microcontroller configured to detect a tool activation signal. 
     
     
         6 . The system of  claim 1 , wherein the protective filter includes at least one sensor located to detect a position of the protective filter. 
     
     
         7 . The system of  claim 6 , wherein the sensor is located to detect an open position or a closed position of the protective filter. 
     
     
         8 . The system of  claim 6 , wherein the sensor is located proximate the protective filter to detect an open position or a closed position of the protective filter. 
     
     
         9 . The system of  claim 6 , wherein the sensor is associated with an actuator capable of moving the protective filter between a closed position and an open position to detect a position of the actuator corresponding to an open position or a closed position of the protective filter. 
     
     
         10 . The system of  claim 6 , wherein the sensor includes at least one of an inductive switch, a capacitive switch, a reflective switch, a photointerrupter, and a microswitch. 
     
     
         11 . The system of  claim 1 , wherein the closed command signal provides a unique identifier code.
