Abstract

An apparatus includes a structure comprising a predetermined breakable region and a mechanical actuator disposed at or proximate the predetermined breakable region. The mechanical actuator comprises an impact member coupled to a spring arrangement, and a restraint member operably coupled to the spring arrangement. A trigger source is operably coupled to an electrical power source. The trigger source, in response to receiving current from the electrical power source, is configured to release or break the restraint member so as to allow the spring arrangement to forcibly move the impact member into contact with, and break, the predetermined breakable region.
