A lock with a support helping to extend the locking range includes a steel rope and a separate female lock body. In one illustrative example, a first message center address associated with a home message center and a second message center address associated with an emergency message center are stored in memory of the mobile device. The fluorescence signals converted into pulse signals by two optical detectors are led to a coincidence circuit, and when two fluorescence signals are measured simultaneously during the predetermined period of time, a neutron signal is output. First and second electrostatic discharge preventing circuits are respectively connected to the odd and even-numbered data signal lines. The quenched material can be formed into a three dimensional physical vapor deposition target.
