In addition, a drag-stabilized version thereof is provided, having canted fins thereon so as to control flight of the projectile via the imposition of drag thereon. Additionally, the projectile is capable of carrying agents, such as crowd control and marking agents, in an agent reservoir, and ejecting same onto a target upon impact.

An improved pneumatic launching apparatus is disclosed having both a partition apparatus for enabling a projectile, such as filled capsules used in paintball, marking devices or crowd control, to be loaded and readied for expulsion and a venting-pressure regulator. When the partition apparatus is in an open position, an aperture is exposed allowing a projectile of complimentary size and shape to transfer to the receiving chamber. The shape of the partition is such that a next projectile is gently cradled and separated from the receiving chamber during a closing movement. Further, the partition facilitates the projectile reaching a containing area and it creates a seal that on the chamber that significantly inhibits the escape of pressurized gas during a firing operation and facilitates the projectile loading into a containing area. The venting-pressure regulator utilizes opposed pistons with an escape mechanism to allow venting to occur without requiring a separate adjustment.

A modular crowd control munition 10 fires a large number of non-lethal soft pellets into a crowd 100 using an explosive charge. The munition 10 contains a pellet matrix 22 that houses the soft pellets 40, and uses a low energy explosive sheet material 50 at the back of the munition 10 to disperse the soft pellets 40. The munition 10 is used for close-in, "last resort", crowd control to replace the necessity of using deadly force.

A crowd control rail assembly includes at least two foldable plastic barricades constructed from two substantially similar integrally molded planar frame units. A planar cross-panel at the upper end of the barricade includes a vertically elongated slot into which the end of an elongated plastic rail unit may be inserted. Notches are provided at each end of the rail. Dimensions of the rail are chosen so that it must be inserted into the slot substantially perpendicular to the planar face of the upper portion of the frame unit and, then when the notch engages the bottom of the slot and the barricade is unfolded, the rail is automatically and securely retained.

A lockable post assembly includes a post member (12) having a vertical axis and an anchor portion (14) at a lower first end thereof. The anchor portion (14) has a head (16) and neck (18), the neck (18) defining a female constriction above the head (16). An anchor socket (22) secured within the ground is adapted to lockably receive the anchor portion (14) so as to hold the post member (12) upright. The anchor socket (22) has a keyed passageway (24) with an inward collar portion (26). The collar portion (26) defines a male constriction above a lower cavity (30). In use, the anchor socket (22) lockably receives the anchor portion (14) by the steps of inserting the anchor portion downwardly in a first orientation about the vertical axis so that the head (16) enters the lower cavity (30), and then rotating the anchor portion (14) to a second orientation about the vertical axis so that the head (16) is underneath or abuts a bottom surface of the collar portion (26). In this way, the post member (12) is held upright and cannot be lifted from the anchor socket (22) without counter-rotating the anchor portion (14) to the first orientation.

A pin locking mechanism selectively permits or resists the rotation of two nested tubular members with respect to each other. The pin has a substantially rectangular cross-section. The pin passes through a pair of holes defined in the outer tubular member, and a pair of slots defined within the inner tubular member. The slots have ends wider than their central portion, so that the pin may only fit within the central portion of the slot when it is substantially parallel to the slot, but may fit within the end portions when it is perpendicular to the slot. The nested tubular members may therefore be rotated with respect to each other when the pin is held substantially parallel with the slot, and rotation is resisted when the pin is held in a perpendicular orientation. A handle at one end of the pin is biased towards the outer tubular member by a spring at the opposite end of the pin. Rotation of the pin is resisted when the handle abuts the outer tubular member, and permitted when the handle is pulled away from the outer tubular member. The pin locking mechanism is particularly suitable for a pivoting base of a crowd control barrier.

“A computer-implemented method and system (“Legion”) for capturing and outsourcing an existing graphical user interface (“GUI”) of an application to a crowd for their collaborative real-time control using an input device are provided. A crowd refers to a dynamic pool of one or a plurality of anonymous worker of varying skill level and/or reliability. The pool is dynamic because workers are able to come and go at their leisure and no specific worker can be relied upon to be available at a given time or to continue working on a job for a specific amount of time. Mediation strategies for integrating the input of multiple crowd workers in real-time is also provided.”
