Electronic weaponry with canister for electrode launch
An electronic weapon with an installed deployment unit, from which wire-tethered electrodes are launched, provides a stimulus current through a target to inhibit locomotion by the target. A canister of compressed gas propels the electrodes. The canister is located in the deployment unit in a manner that facilitates the design and manufacture of a relatively narrow deployment unit.
1. A deployment unit for providing a current through a provided target, the deployment unit comprising:
a body comprising a first tube, a second tube, and a cavity;
a first electrode positioned in the first tube;
a second electrode positioned in the second tube; and
a canister positioned in the cavity, the canister for providing a pressurized gas to the first tube and the second tube to launch the first electrode and the second electrode toward the target to provide the current through the target, the current for inhibiting voluntary movement by the target; wherein with respect to a direction of travel of the first electrode toward the target, the cavity is positioned in the body rearward of the first tube and the second tube; wherein
the body further comprises a passage that fluidly couples the cavity to the first tube and the second tube; and
the passage directs a flow of the pressurized gas from an outlet of the cavity to an inlet of the first tube and an inlet of the second tube.
2. The deployment unit of claim 1 wherein as the pressurized gas traverses the passage from the canister to at least one of the first tube and the second tube, a direction of the flow of pressurized gas changes three times.
3. The deployment unit of claim 2 above wherein a magnitude for each change of direction of the flow of pressurized gas is about 90 degrees.
4. A deployment unit for providing a current through a provided target, the deployment unit comprising:
a body comprising a first tube, a second tube, and a cavity;
a first electrode positioned in the first tube;
a second electrode positioned in the second tube; and
a canister positioned in the cavity, the canister for providing a pressurized gas to the first tube and the second tube to launch the first electrode and the second electrode toward the target to provide the current through the target, the current for inhibiting voluntary movement by the target; wherein with respect to a direction of travel of the first electrode toward the target, the cavity is positioned in the body rearward of the first tube and the second tube; wherein
the deployment unit further comprises a cap;
the body further comprises a passage;
the cap couples to the body to form a portion of the passage;
the passage fluidly couples the cavity to the first tube and the second tube; and
the passage directs a flow of the pressurized gas from an outlet of the cavity to an inlet of the first tube and an inlet of the second tube.
5. A deployment unit for providing a current through a provided target, the deployment unit comprising:
a body comprising a first tube and a cavity, the first tube having a first axis along a length of the first tube;
a first electrode positioned in the first tube; and
a canister positioned in the cavity, the canister having a second axis along a length of the canister, the canister for providing a pressurized gas to the first tube to launch the first electrode toward the target to provide the current through the target, the current for inhibiting voluntary movement by the target; wherein
as the pressurized gas traverses the passage from the canister to the first tube, a general direction of flow of pressurized gas changes more than once.
6. The deployment unit of claim 5 wherein a cumulative magnitude for all changes of direction of flow of pressurized gas is more than 180 degrees.
7. A deployment unit for providing a current through a provided target, the deployment unit comprising:
a body comprising a first tube, a cavity, and a passage, the passage fluidly couples the cavity to the first tube;
a first electrode positioned in the first tube;
a canister positioned in the cavity, the canister for providing a pressurized gas to launch the first electrode toward the target to provide the current through the target, the current for inhibiting voluntary movement by the target; wherein:
the passage directs a flow of the pressurized gas from an outlet of the cavity to an inlet of the first tube; and
as the pressurized gas traverses the passage from the canister to the first tube, a general direction of flow of pressurized gas changes at least three times.
8. The deployment unit of claim 7 wherein:
the deployment unit further comprises a cap; and
the cap couples to the body to form a portion of the passage.
9. The deployment unit of claim 7 further comprising a cover, wherein the cover couples to the body to close the cavity.
10. The deployment unit of claim 7 wherein:
the first tube has a first axis along a length thereof;
the canister has a second axis along a length thereof;
an orientation of the first axis to the second axis is about 90 degrees.
11. The deployment unit of claim 7 wherein with respect to a direction of travel of the first electrode toward the target, the cavity is positioned in the body rearward of the first tube.
12. The deployment unit of claim 7 further comprising a second electrode, wherein:
the body further comprises a second tube;
the second electrode is positioned in the second tube;
the canister for further providing the pressurized gas to the second tube to launch the second electrode toward the target to provide the current;
the passage further directs the flow of the pressurized gas from an outlet of the cavity to an inlet of the second tube; and
as the pressurized gas traverses the passage from the canister to the second tube, the general direction of flow of pressurized gas changes at least three times.
13. The deployment unit of claim 12 wherein:
the second tube has a first axis along a length thereof;
the canister has a second axis along a length thereof;
an orientation of the first axis to the second axis is about 90 degrees.
14. The deployment unit of claim 12 wherein with respect to a direction of travel of the second electrode toward the target, the cavity is positioned in the body rearward of the second tube.
