Abstract: Police officers use conducted electrical weapons (“CEWs”) and cameras. A camera and a CEW may cooperate to improve the performance and use of the CEW and evidence collection by the camera. A camera and a CEW may also cooperate to improve the safety of the user and the target. Improvements may include improving targeting of the CEW, identifying and classifying body parts of the target as suitable or unsuitable for electrode deployment, adjusting electrode trajectory prior to launch, and automating electrode launch. Evidence collection may be improved by recording placement of electrodes on the target. Safety of the target may be improved by monitoring the movements of the target and altering characteristics of the delivered stimulus signal if potential harm to the target may occur.

Abstract: An air launch apparatus includes a frame, a grip, and a plurality of sidewalls and also includes a hollow substantially cylindrical barrel having a central longitudinal axis. The air launch apparatus further includes a piston disposed substantially concentric with the barrel. The piston is configured to move longitudinally along the outer surface of the barrel in directions parallel to the longitudinal axis. The air launch apparatus also includes a nut that is configured to engage the piston as a front block carrying the nut is drawn rearward toward a user, and to hold the piston stationary relative to the front block while so engaged. A plunger, fixedly connected to the piston, is configured to move with the piston. Movement of the piston and plunger, forward during cocking draws air into a volume within an air chamber of the air launch apparatus. The plunger, together with the piston, is driven rearward (toward the user) during firing of the air launch apparatus.

Abstract: A rotatable buttstock mount can include a tube, a boss, a support frame including a rearward ring and a guide pin in a guide slot such that the support frame can rotate relative to the tube. When a buttstock is secured to the mount, the buttstock can rotate with the frame and thereby change the axial angle of the buttstock relative to the weapon to which the mount is secured, thereby providing a user with a variety of angular orientations of the buttstock for different shooting configurations. The mount can rotate freely relative to the tube, being actuated simply by overcoming a friction interface between components and/or a detent between the components. Thus, actuation of the mount and rotation of the buttstock to a custom angular position can be easily and quickly implemented to obtain a selected configuration for the user.
