  • Patent number: 6799517
    Abstract: The Mixed Mine Alternative (MMA) System is a military system designed for use in mechanized warfare. The MMA System has three components, MMA smart Antitank mines, MMA Antihandling Sensors linked to the MMA smart Antitank mines, and MMA Remote Control Units (RCU). The MMA smart Antitank (AT) mines contain a primary sensor system hardened against countermeasures and a kill mechanism similar to existing scatterable AT mines. The MMA AT mine is capable of transmit and receive communications with a Remote Control Unit and with the MMA Antihandling Sensors (AH). The communications capabilities and processors in the MMA AT and the MMA AH allow the system to establish MMA AT to MMA AH links after the mines have been scattered. MMA AT will be linked to MMA AH that are within their lethal radius. The MMA AT mine processors allow the mine primary antitank sensor to be on or off. The mine may receive and act on detonate instructions from the primary antitank sensor, from the antihandling sensors, or from the MMA RCU.

  • 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.

  • Patent number: 5069136
    Abstract: A two-stage release self-righting mechanism and method employ a pair of primary and secondary releasable holder assemblies which respective hold upper and middle portions of leaf spring arms in a stowed position against the side wall of a load such as a submunition launcher tube. The primary holder assembly is released first which permits release of a portion of the energy stored by the spring legs, causing them to partially extend from the stowed position to a partially deployed position and partially erect the submunition. Then, a short time later, the secondary holder assembly is released, permitting release of the remaining energy stored by the spring legs, causing them to fully extend to a fully deployed position and complete the erecting of the submunition.

  • Patent number: 5067096
    Abstract: A target engagement system uses target motion analysis to determine a target engagement decision for ground targets, such as vehicles. The input to the engagement system is the target azimuth as a function of time. A detect algorithm issues and records a detect azimuth when confirmation is made that a valid target is being tracked and legitimate azimuth information is being provided. The engagement algorithm then begins and records the time intervals it takes for the target to cross two sectors, each covering 20.degree. and separate by 10.degree.. Thus, first time interval is measured from detect azimuth to 20.degree. after detect azimuth, and the second time interval is measured from 30.degree. after detect azimuth to 50.degree. after detect azimuth. When the first and second time intervals have been recorded, the ratio of the first time interval to the second time interval is calculated. If this ratio is greater than 2.0, then the target is estimated to be within range and is subsequently attacked.
