Back-up electric power generator for electronic components attached to automatic firearms

A rifle comprising:

• a buffer body that includes a magnet generating a magnetic field, the magnet installed in the buffer body of the rifle;
• a buffer tube that includes a conductor assembly having a plurality of loops of electrically conductive wire configured in or on the buffer tube so that the buffer body moves through the plurality of loops of electrically conductive wire;
• a firing chamber to generate a fluid pressure to drive movement of the buffer body through the plurality of loops of electrically conductive wire;
• a rectifier or diode attached to the conductor assembly by a first set of electrically conductive wires;
• and
• an electric power storage unit attached to the rectifier or diode by a second set of electrically conductive wires.

A weapon able to generate and store electric power when the weapon is operated, the weapon comprising:

• first and second components;
• a magnet generating a magnetic field, the magnet installed in or on the first component of the weapon;
• a conductor assembly comprising a plurality of loops of electrically conductive wire, the conductor assembly installed in or on the second component of the weapon, wherein the first and second components are configured to move relative to each other;
• a firing chamber to generate a fluid pressure to drive movement of the first and second components relative to each other such that an electromotive force is generated;
• a rectifier or diode attached to the conductor assembly by a first set of electrically conductive wires;
• and
• an electric power storage unit attached to the rectifier or diode by a second set of electrically conductive wires.
