US Patent 8087335 Systems and methods for repeating area denial

Systems and methods inhibit locomotion of a human or animal target in a denial zone. Acquiring the target includes forming a prediction of at least two locations of impact on the target and testing the prediction according to criteria that may include whether the locations are within a boundary corresponding to the target and whether the locations are separated by a minimum physical and/or electrical distance. The two locations may serve for conducting a current through the target for impeding locomotion by the target. The current may be repeated in response to determining that locomotion was not sufficiently impeded. Determination may depend on analysis of video of the target.
