Abstract: A net throwing device for use in combination with a compressed air powered launching device is provided with a pod including an axial space, tubes disposed around the axial space, and a slot formed on an edge; a net disposed in the axial space; weights each disposed in one of the tubes; and a casing including a forward oriented projection on an edge of a front end, the projection being fitted in the slot to secure the casing and the pod together, and a protrusion adjacent to the forward oriented projection. At least one of the tubes is inclined with respect to an axis of the axial space. At least one of the tubes is parallel to the axis of the axial space.

Abstract: A series of doors, locks, walls and signage present a vestibule room or safety enclosure for use in controlling access into a secured space. Exterior signage regarding weapon detection equipment and the appearance of a mantrap enclosure is used to dissuade visitors from bringing weapons into the secured area. A person within the safety enclosure may always exit through the exterior door and thus avoid harm in the event of a natural disaster.

Abstract: A criminal arresting method includes preparing a frame assembly, activating a first weight releasing device to allow a first weight to fall inside the frame assembly, activating reducing of size of a first loop inside the frame assembly, activating a second weight releasing device to allow a second weight to fall relative to the frame assembly and activating reducing of size a second loop inside the frame assembly.

Abstract: A walk-through security device having a personal effects view port and methods of operating and manufacturing the device. In one embodiment, the device includes: (1) a shell having an opaque sidewall with at least one material detector located therein and (2) a view port, located on the opaque sidewall, that allows a person passing through the shell to view a personal effect located on an opposite side of the sidewall.

Abstract: A net trapping system for capturing a robber immediately is used in a place of business such as a bank. The device looks like a storing box and is installed above the entrance of the business. When a robbery takes place and the system is activated, an infrared detecting device determines if a robber is in a zone beneath the storing box. A net, a curtain, and a plurality of barriers will drop down immediately and simultaneously. After a lifting motor is activated, the system traps the robber and suspends him above the floor.

Abstract: A law enforcement baton for enhanced suspect control and apprehension comprises detachable, coextensive, proximal and distal lengths with a handle portion removably perpendicularly attached thereto with the handle portion and distal length being of identical construction and interchangeable upon the baton. The distal length includes a central bore with a plurality of reduced diameter bore holes extending parallel thereto in annularly spaced relation thereabout. A net having a plurality of elastic lines with retaining elements attached thereto is removably positioned within the central bore and the plurality of bore holes, respectively. The proximal length includes an opening wherein a compressed air canister is removably inserted with the sealed end thereof being in fluid communication with the bore openings in the distal length when the proximal and distal lengths are attached together.

Abstract: A device is provided which enables a person to capture a fugitive without injuring the fugitive. The device comprises a tubular body having angularly disposed tubular barrels extending therefrom. The barrels each have a slot extending along the length thereof such that a pair of projectiles can be loaded into the device while a flexible line interconnects the pair of projectiles.To catch the fugitive, the device is aimed at the fugitive and the pair of projectiles are propelled from the barrels in diverging lines of flight. As the line extends between the diverging projectiles, the fugitive is engaged by the line. The momentum of the moving projectile causes the projectiles to wrap the line about the fugitive thereby entangling him and preventing him from further fleeing.

Abstract: Access to a space is impeded by the generation of a sticky foam from a tacky polymeric resin and a low boiling solvent.

Abstract: A system for disabling robbers has an ejector arranged for projecting needle-like discrete articles across a passageway which a robber must traverse during flight, and toward a receptor disposed opposite of and spaced from the ejector across the passageway. Articles which do not strike the body of the robber will be received by the receptor. A tranquilizer is provided on the articles for rendering the robber unconscious in seconds. Personnel inside the building subjected to robbery can activate the system, either directly as the robber attempts to leave the building, or indirectly by actuating a sensor system when the robbery is first instigated.
