Systems and methods for a flexible unitary manifold
A conducted electrical weapon (“CEW”) impedes locomotion of a human or animal target by providing a stimulus signal through the target via one or more electrodes. The CEW includes a propulsion system. The propulsion system provides a force that launches the one or more electrodes toward the target to deliver the stimulus signal. The propulsion system includes a canister of pressurized gas, an anvil, and a manifold. The canister releases the pressurized gas. The manifold delivers the pressurized gas to the electrodes to launch the electrodes. The manifold may be formed of flexible material. The manifold may be formed as a single piece. A single-piece manifold reduces loss of pressurized air. The housing of the deployment unit supports the manifold against structural failure of the manifold.
