A method is performed by an electronic weapon system. The electronic weapon system is aimed in a first direction toward a target. The method includes, deploying an electrode of the system in a second direction different from the first direction, to compensate for drag of a tether wire deployed with the electrode. For example, a tether wire deployed from a tether wire store located adjacent to a cavity from which the electrode is propelled may exert a drag force causing inaccuracies of the propelled electrode. Compensation is accomplished, for example, by virtue of shaping the cavity. Compensation improves accuracy of the electrode striking the target.

What is claimed is: 1. A method performed by an electronic weapon system aimed in a first direction toward a target, the first direction being a line within a vertical plane, the system comprising at least one electrode whose effectiveness is decreased with increased distance between the electrode
What is claimed is: 1. A method performed by an electronic weapon system aimed in a first direction toward a target, the first direction being a line within a vertical plane, the system comprising at least one electrode whose effectiveness is decreased with increased distance between the electrode and the vertical plane, the method comprising: deploying the electrode of the system in a second direction away from the vertical plane, to compensate for a horizontal component of drag of a conductive tether wire of the system deployed with the electrode, wherein the horizontal component of drag increases the effectiveness of the electrode by moving the electrode toward the vertical plane. 2. The method of claim 1 wherein: the electrode is deployed from a cavity comprising a surface; and deploying comprises guiding the electrode along the second direction in accordance with a shape of the cavity. 3. The method of claim 2 wherein the cavity further comprises a first axis of symmetry aligned with the second direction. 4. The method of claim 3 wherein a second axis that is aligned with the first direction makes an acute angle with the first axis. 5. The method of claim 4 wherein the angle is about 2 degrees. 6. The method of claim 2 wherein the cavity further comprises a surface and a D-shaped cross section, and the surface comprises the flat of the D. 7. The method of claim 1 wherein: the system comprises and electronic weapon and a cartridge; and deploying comprises propelling the electrode and at least a portion of the tether wire away from the cartridge in response to a signal provided by the weapon to the cartridge. 8. The method of claim 1 further comprising providing a first voltage to conduct a current through the electrode that halts locomotion of the target. 9. The method of claim 1 wherein the system compromises a weapon and a cartridge, the method further comprising; providing from the weapon a first signal to the cartridge to initiate deploying, the first signal comprising a first average voltage magnitude; and providing a second signal to conduct a current through the electrode that halts locomotion of the target, wherein the second signal comprises a second average voltage magnitude greater than the first average voltage magnitude. 10. The method of claim 1 wherein the second direction differs by about 2 degrees from the first direction. 11. A deployment unit for use with an electronic weapon aimed in a first direction toward a target, the first direction being a line within a vertical plane, the deployment unit comprising: a conductive tether wire mechanically coupled to the deployment unit; and an electrode that is deployed from the deployment unit to strike the target, the electrode being deployed in a second direction away from the vertical plane, the electrode mechanically coupled to the tether wire; wherein the tether wire exerts a horizontal component of drag on the electrode during deployment; the second direction differs from the first direction to compensate for the horizontal component of drag; and the horizontal component of drag increases the effectiveness of the electrode by moving the electrode toward the vertical plane. 12. The deployment unit of claim 11 further comprising a cavity from which the electrode is deployed, the cavity comprising a shape that guides the electrode along the second direction. 13. The deployment unit of claim 12 wherein the cavity further comprises a first axis of asymmetry aligned with the second direction. 14. The deployment unit of claim 13 wherein a second axis that is aligned with the first direction makes an acute angle with the first axis. 15. The deployment unit of claim 14 wherein the angle is about 2 degrees. 16. The deployment unit of claim 12 wherein the cavity further comprises a D-shaped cross section. 17. The deployment unit of claim 11 further comprising a propellant, initiated by a signal received from the electronic weapon to propel the electrode and at least a portion of the tether wire away from the electronic weapon. 18. The deployment unit of claim 11 further comprising a circuit that receives a first voltage to conduct a current through the electrode that halts locomotion of the target. 19. The deployment unit of claim 11 further comprising: a first circuit that receives a first signal to initiate deploying, the first signal comprising a first average voltage magnitude; and a second circuit that receives a second signal to conduct a current through the electrode that halts locomotion of the target, wherein the second signal comprises a second average voltage magnitude greater than the first average voltage magnitude. 20. The deployment unit of claim 11 further comprising: a cavity from which the electrode is deployed; and a wire store from which at least a portion of the tether wire is deployed, the wire store not aligned with the cavity along the second direction. 21. The deployment unit of claim 11 wherein the second direction differs by about 2 degrees from the first direction. 22. An electronic weapon system for aiming in a first direction toward a target, the first direction being a line within a vertical plane, the electronic weapon system comprising: a conductive tether wire mechanically coupled to the deployment unit; and an electrode that is deployed from the deployment unit to strike the target, the electrode being deployed in a second direction away from the vertical plane, the electrode mechanically coupled to the tether wire; wherein the tether wire exerts a horizontal component of drag on the electrode during deployment; the second direction differs from the first direction to compensate for the horizontal component of drag; and the horizontal component of drag increases the effectiveness of the electrode by moving the electrode toward the vertical plane. 23. The electronic weapon system of claim 22 further comprising a cavity from which the electrode is deployed, the cavity comprising a shape that guides the electrode along the second direction. 24. The electronic weapon system of claim 23 wherein the cavity further comprises a first axis of symmetry aligned with the second direction. 25.
