    Abstract: A paint ball land mine comprising multiple PVC parts detonates and marks simulated casualties. The mine may be easily field stripped by hand. The mine forcibly detonates in response to physical contact without unbalancing, so that tilting forces that otherwise misaim the mine are avoided. A rigid cylindrical two-part base threadably receives a removable top. A sealed interior for holding colored fluid is defined therebetween. A gas cartridge housed vertically interiorly of the base may be detonated when forced into contact with a puncture pin. An integral, upwardly projecting dome mounts a detonator assembly, comprising a tubular plunger that slidably contacts the cartridge when fired. Escaping gases pressurize the mine interior, forcing colored liquid upwardly and outwardly through multiple discharge passageways that are angled acutely to aim fluid away from the center. A removable safety pin, temporarily engaging the plunger, may be “pulled” to “set” the mine.

The microprocessor determines therefrom the location of the largest target or the largest cluster of targets in the environment and triggers the detonation of the mine such that the projectiles are jettisoned in a conical pattern toward the largest target or the largest cluster of targets for a more efficient destruction of the targets.

  • Patent number: 5600086
    Abstract: A device for detecting a target and for detonating an explosive device includes a displaceable trigger wire attached to a movable or deformable trigger member, and a detection device for detecting movement or deformation of the trigger member. In the case of a movable trigger member, movement of the trigger wire causes movement of the trigger member, and the detection device generates a detonation signal in response to the movement to cause detonation of the explosive. In the case of a deformable trigger member, movement of the trigger wire causes deformation of the trigger member, and the detection device generates a detonation signal in response to the deformation that causes the explosive device to detonate. The detection device may be located in the explosive device, with the trigger wire extending out away from the explosive device. Alternately, the detection device may be located in a support member located apart from the explosive device.

  • Patent number: 5474452
    Abstract: A system for simulating indirect weapon fire is disclosed which serves to greatly increase the realism and training value of tactical engagement simulation exercises when suitably interfaced with existing MILES-type detecting/indicating equipment. System simplicity, effectiveness, and security are achieved using a referee-operated, hand-held actuating device emitting at a first acoustic frequency to selectively transmit actuating signals to one or more pre-positioned explosion simulation devices, which then transmit multidirectional sound at a second acoustic frequency. MILES-equipped point targets located within the effective range of the multidirectional sound respond to the second frequency signal and determine the effectiveness of the simulated explosion using a pre-established hierarchy of hit/near miss/weapon-type criteria.

  • Patent number: 5423266
    Abstract: This invention is a relatively simple and yet highly efficient disabling mine that is approximately the size of a tube of lip balm or a 20 gauge shotgun shell. A detonator and its associated detonator pin is adapted to fire a detonator cap in the end of a charge chamber. The charge chamber is filled with magnesium except for the area immediately adjacent the detonator cap which is gunpowder that is used as a magnesium igniter. When the mine of the present invention is ignited, it will burn fiercely at a temperature in excess of 3000 Fahrenheit for a period of 5 to 6 seconds which will disable personnel as well as vehicles and other enemy equipment coming in contact therewith. Because of the relatively small size of the mines of the present invention, at least 50 of the same can be carried by a single soldier in a bandolier.

  • Patent number: 5353676
    Abstract: An apparatus and method for remotely disassembling a failed high explosive ype mine. The apparatus is mounted on a mobile chassis and has a remote operator shelter for control of the apparatus. The apparatus has a stripper assembly to remove appendages from the body of the mine. A chuck assembly moves the stripped body of the mine to a cutter assembly and rotates the body of the mine so that the electronics assembly is severed from the body of the mine. A puller assembly extracts the safe and arming device from the high explosive filler in the body of the mine. In an alternate embodiment, a rammer assembly has a pressing cylinder to push the electronics assembly and the safe and arming device from the center of the body of the mine as the outer portion of the body of the mine is firmly retained on the frame of the rammer assembly. Video cameras on the apparatus are provided to permit remote control of the disassembly.

  • Patent number: 5345853
    Abstract: An anchoring system for anchoring a projectile launcher to the ground. The launcher includes a tubular body accommodating at least a projectile to be fired and a propellant charge. The system further includes least one anchoring element that penetrates the ground when the projectile is fired. The anchoring element can be moved between a first position in which it is at a distance from the ground and held by a body of the launcher by means of a temporary attachment device, and a second position in which it penetrates the ground. A control system causes the anchoring spike to move automatically from its first to its second position and is constituted by the pressure of the gases resulting from ignition of propellant charge.

  • Patent number: 5261328
    Abstract: In a broad-area defense mine, the inclination under which an active member can rise or can be fired from an ambush position can be varied with the aid of at least one adjusting member between the positioning frame and a mounting or support for the active member which, in turn, are connected by way of a universal joint. In this arrangement, the mine, in the same way and with equal reliability as heretofore, combats a target within a specific area, but it is possible by means of this device to defend a substantially larger zone: the mine is transported, within the larger zone, to the "correct" site.

  • Patent number: 5243915
    Abstract: In known droppable mines it customarily becomes necessary, because of the consistency and slope of the ground, to right the mine into a position favorable for its action, with such a position being fixable, if possible, for the entire duration of deployment independently of extraneous influences.Since in the past such fixing was realized in the known mines only in a complicated and unsatisfactory manner, the mine (10) according to the invention includes a sack (18) which is arranged below a righting balloon (16) and is filled with a hardenable foam. In this way, the stability of the mine (10) is decisively improved. Due to the underside (22) of the sack (18) being kept permeable, the foam is also able to escape into a zone (34) between the ground (12) and the sack (18) and cause the mine (10) to adhere to the ground (12) in its position.
