Abstract

A firearms safety device in the form of remotely armed ammunition includes a firearms cartridge for use in a use with a conventional firearm having a trigger-actuated hammer with a firing pin. The cartridge includes a firing circuit that is operatively associated with a primer for igniting a conventional propellant charge. A firing sequence is initiated by the impact of the firing pin with the base of the cartridge. An arming circuit allows the firing sequence to proceed to ignition of the propellant only if a receiver within the arming circuit receives an appropriate arming signal transmitted by a remote control module. In the absence of an appropriate arming signal, the cartridge is permanently disabled.

Claims

1. Remotely-armed ammunition for use with a conventional firearm having a trigger-actuated firing pin, the ammunition comprising;

a cartridge having a case having, at one end, a pocket into which a primer load is inserted, propellent within the case, and, at an end opposite the pocket, an open end into which a projectile is inserted;

a primer load including circuitry which selectively permits igniting a primer, the primer load being inserted into the pocket of the cartridge; and

means for remotely controlling operation of the primer load which includes a receiver for receiving an arming signal when the receiver is within a predetermined range of a transmitter which is separate from the cartridge and the firearms.

2. Remotely-armed ammunition according to claim 1 wherein the primer load comprises a barrier member located at one end of the primer load, wherein the circuitry is positioned adjacent to the barrier member, and a primer is electrically connected to the circuitry, and the primer is located at an end of the primer load opposite the barrier member.

3. Remotely-armed ammunition according to claim 2 wherein the circuitry comprises an energy power source, an arming circuit for receiving an arming signal, and a firing circuit for igniting the primer.

4. Remotely-armed ammunition according to claim 3 wherein the energy power source is a battery.

5. Remotely-armed ammunition according to claim 3 wherein the energy power source is a capacitor.

6. Remotely-armed ammunition according to claim 3 wherein said arming circuit includes a fail-safe circuit for disabling said cartridge to prevent the firing thereof upon an attempt to fire the ammunition in the absence of the arming signal.

7. Remotely-armed ammunition according to claim 1 wherein the receiver receives electromagnetic signals at a frequency which must match the frequency of the electromagnetic signals transmitted by the transmitter to constitute the arming signal.

8. A primer load comprising:

a barrier member located at one end of the primer load;

circuitry positioned adjacent to the barrier member, the circuitry including a receiver which is activated only upon receiving an electromagnetic signal at a predetermined frequency from a transmitter separate from the primer and a firearm used to fire the primer;

and an electrically-ignitable primer electrically connected to the circuitry, the primer being located at an end of the primer load opposite the barrier member, the primer load including circuitry which selectively permits igniting a primer.

9. The primer load having the circuitry according to claim 8 comprising an energy power source, an arming circuit for receiving an arming signal, and a firing circuit for igniting the primer.

10. The primer load having the circuitry according to claim 9 wherein the energy power source is a battery.

11. The primer load having the circuitry according to claim 9 wherein the energy power source is a capacitor.

12. A fail-safe ammunition system comprising a transmitter;

and a cartridge including;

a case having, at one end, a pocket into which a primer load is inserted, propellent within the case, and, at an end opposite the pocket, an open end into which a projectile is inserted;

a primer load including circuitry which selectively permits igniting a primer upon receiving a transmitted signal from the transmitter, the primer load being inserted into the pocket of the cartridge, the transmitter being separate from the cartridge and a firearm used to fire the cartridge.

13. A fail-safe ammunition system according to claim 12 wherein the transmitter transmits an electromagnetic signal on a predetermined frequency and the circuitry which selectively permits igniting the primer contains a receiver which receives only on the predetermined frequency.
