Abstract
A conducted electrical weapon (“CEW”) deploys wire-tethered electrodes after generation of an ignition signal. The ignition signal is provided to a deployment unit. The deployment unit includes a primer material adjacent a conductor. The conductor conducts the ignition signal outside the primer material. A temperature of the conductor increases in response to receiving the ignition signal. The primer material ignites in response to the increase in temperature of the conductor.
Claims20
A propulsion module, comprising:
- an ignition cap, wherein the ignition cap comprises a base portion opposite an inner receptacle portion, and wherein the base portion comprises a larger radius than the inner receptacle portion;
- a primer cup coupled to the inner receptacle portion of the ignition cap;
- an ignition pin comprising a first end opposite a second end, wherein the first end is positioned within the primer cup, and wherein the second end extends through the base portion of the ignition cap;
- and
- a primer material positioned within the primer cup, wherein in response to an ignition of the primer material the primer cup is configured to separate from the inner receptacle portion of the ignition cap to permit a motion of the primer cup in a direction away from the ignition cap.
A deployment unit for a projectile launcher comprising:
- a projectile;
- and
- a propulsion module configured to cause deployment of the projectile, the propulsion module comprising:
- an ignition cap, wherein the ignition cap comprises a base portion opposite an inner receptacle portion, and wherein the base portion comprises a larger radius than the inner receptacle portion;
- a primer cup coupled to the inner receptacle portion of the ignition cap;
- a primer material positioned within the primer cup, wherein in response to an ignition of the primer material the primer cup is configured to separate from the inner receptacle portion of the ignition cap;
- a puncture tip;
- and
- a propellant capsule positioned between the primer cup and puncture tip, wherein separation of the primer cup from the inner receptacle portion of the ignition cap causes the propellant capsule to contact the puncture tip and release a propulsion force, and wherein the propulsion force is configured to cause deployment of the projectile.
A method of deploying a projectile using a propulsion module, the method comprising:
- receiving an ignition signal;
- igniting a primer material in response to the ignition signal, wherein the primer material is positioned within a primer cup, wherein the primer cup is coupled to an ignition cap, wherein the ignition cap comprises a base portion opposite an inner receptacle portion, wherein the base portion comprises a larger radius than the inner receptacle portion, wherein the inner receptacle portion is coupled to the primer cup, and wherein the primer cup is positioned proximate the projectile;
- separating the primer cup from the inner receptacle portion of the ignition cap in response to the igniting of the primer material, wherein the separating of the primer cup transfers a propulsion force generated by the igniting of the primer material directly to the projectile;
- and
- deploying the projectile in response to the primer cup transferring the propulsion force generated by the igniting of the primer material directly to the projectile.
