ABSTRACT:
An apparatus for electronically controlling the activation of a lock-release mechanism comprising a small, lightweight portable housing that can be easily carried and includes electromechanical means for converting mechanical movement initiated by an operator to electrical signals and an energization source for powering both the electromechanical means and the lock-release mechanism. The lock-release mechanism includes an electronic decoder and detector for receiving the signals generated by the electromechanical means and for receiving power from the energization source within the portable housing. In response to a correct signal code, the electronic decoder and detector in the lock-release mechanism releases an associated lock, thereby freeing the structure secured by the lock.
