The present invention discloses a novel method to improve the selectivities of polybenzoxazole membranes prepared from aromatic polyimide membranes for gas, vapor, and liquid separations. The reset lock-out mechanism prevents the resetting of electrical connections between input and output conductors if the circuit interrupting mechanism used to break the connection is non-operational or if an open neutral condition exists. The first and second conductive ends include first and second concave recesses, which nest with the first and second weldable members, respectively. The snapshot may include a single file, a single directory, a plurality of files within a directory, a plurality of directories, a path on the file system that includes nested files and subdirectories, or more than one path on the file system that each includes nested files and directories.
