Fast acting active protection system
A fast acting active protection system for military vehicles defeats RPG (rocket propelled grenade) threats fired from close ranges. The system minimizes the hazard to troops and civilians nearby. The system uses a plurality of passive sensors to locate the threat and initialize the system. A low cost radar or laser tracker is used as the means to determine range, velocity, and (if required) angular position of the threat. The countermunition used may be one of several choices, with the requisites being that the countermunition provides fast response with low inertia, and is able to damage or destroy the detected threat. A multi-barrel recoilless gun is the weapon of choice. A launching device is used to deploy and aim the countermunition and the tracking means. On board software and electronics are used to control the system.

Ordnance firing system
An ordnance system of the present invention may include or feature any one or more of: a control unit, one or more effectors (detonators, initiators, shaped charges and the like), and a two-, three- or four-wire communication bus between the control unit and the effectors; an addressable system in which all the effectors can be connected to the same communication bus and the control unit can issue coded signals on the bus addressed to a specific effector; inductive coupling between the effectors and the communication bus; and a multi-voltage level communication system in which communication signals are carried at a first voltage and arming signals are provided at a second, higher voltage. Other features may include two-way communication between effectors and the control unit and the de-centralization of firing control so that the control unit does not have exclusive control over whether the effectors function. As a result, the individual effectors possess decision-making ability and, for purposes of this invention, may be referred to as "intelligent" effectors. To participate in the decision-making process, effectors of this invention may be equipped with sensors or other diagnostic circuitry whose condition is checked for satisfactory output before functioning is permitted to occur.

Method and apparatus for locating the trajectory of an object in motion
An object locating system detects the presence of an object as it passes through two consecutive planar fields of view. Two pairs of optical sensor arrays with multiple, directed, pixel detectors observe the object from two angles as the object passes through each consecutive field of view. The locations of penetrations of the respective fields of view are calculated by triangulation. Using this data, the known location of the take-off point and / or the delay between penetrations, the trajectory of the object in time and space is calculated. Applications include projecting the range of a driven golf ball, measuring the respective arriving and departing velocities of a hit baseball, and determining the trajectory and origin of an arriving projectile, as in the case of the threat to a military vehicle.

Explosive reactive armor with momentum transfer mechanism
ActiveUS20060086243A1Enhanced interactionImprove protectionDefence devicesArmoured vehiclesDetonationSlant angle
Disclosed is an explosive reactive armor with a momentum transfer mechanism by developing a new protection mechanism in which a momentum transfer mechanism by detonation of a reactive material is integrated with a thickness increase mechanism. In this explosive reactive armor with the momentum transfer mechanism, a flying element always travels with a vertical angle or a slant angle with respect to an ongoing direction of the threat such that a momentum of the flying element is transferred to the threat effectively. As a result of this, shear force is induced over an entire length of the threat and thus the threat can be destroyed. Therefore, a protection effect can always be achieved regardless of an impact angle of the threat. Also, a protection capability can be achieved even in case of a vertical impact which is the most vulnerable case for the existing explosive reactive armor.
