Abstract: An alarm system for remotely locking down rooms, or buildings, during an emergency includes a plurality of locks that are coupled to a plurality of doors to secure the plurality of doors in a closed position. A plurality of motors are operatively coupled to the plurality of locks wherein each motor of the plurality of motors is actuatable to engage a respective lock of the plurality of locks. The plurality of motors are actuatable via an electrical signal. A remote control is positionable within each room. Each remote control includes a remote transceiver and a door lock button. The remote transceiver sends the electrical signal to a respective motor of the plurality of motors when the door lock button is actuated.

Abstract: A method for forming semiconductor devices using a semiconductor substrate having first and second opposed surfaces and including first and second device regions includes directing a beam of laser light at the substrate such that the beam of laser light is focused within the substrate between the first and second surfaces thereof and the beam of laser light forms a thermally weakened zone (TWZ) in the substrate. The TWZ extends between the first and second device regions and defines a break line.
