Abstract: A novel adaptive armor system includes an array of armor elements, a hinge system, an actuator mechanism, and a tension support. The hinge system permits rotation of the armor elements about respective axes to change their orientation with respect to the vehicle body. The tension support is movably coupled between the actuator mechanism and the array and bears at least some of the weight of the armor elements in tension. The actuator mechanism moves the tension support (e.g., under the control of a controller) to change the angular orientation of at least some armor elements. Each armor element can include a tray that removably receives different ERA cassettes therein. An exemplary method includes detecting an incoming threat projectile, assessing at least one characteristic specific to the projectile, and changing the angular orientation of the array in a manner to defeat the incoming projectile. The invention provides threat adaptability while minimizing added weight and vehicle size.

Abstract: An armor system and method for the protection of an environment. The armor system includes at least one, and generally a plurality of flexible strands, a first strand support system, and a control subsystem. The control subsystem is configured to manually or automatically adapt the configuration of the armor system in response to a ballistic threat. The armor system may further include at least one of a drift gap and a spall catcher positioned between the flexible strand and the environment to be protected. The configuration can include activating a wave shape along the flexible strand. The configuration can include multiple layers of the flexible strands. The flexible strands may be implemented as a curtain. The strands may be deployed into an open-top container.

Abstract: A method includes presenting to an online learner a first question. The method also includes receiving a first answer of the online learner to the first question. The method also includes presenting to the online learner a second question that requests a justification for the first answer. The method also includes receiving a second answer of the online learner to the second question. The method also includes storing, in a learner account of the online learner, the second answer in association with the first answer. The method also includes finding a different second answer of a different online learner and which is associated with a different first answer of the different online learner. The method also includes presenting the different second answer to the online learner.

Abstract: Reactive armor that includes a casing having a plurality of walls, a back, and a cavity formed therebetween; a cover that closes the cavity and forms a strike face; a filler placed within the cavity, the filler comprising a disruptive material; and an explosive. To defeat projectile or projectile related threats, the reactive armor substantially, but not necessarily wholly, implements laterally oriented force mechanisms, erosion mechanisms, and bulking mechanisms, e.g., explosive forces, with respect to the strike face.

Abstract: A reactive armor that includes a tube having a substantially central longitudinal axis, and at least two force reaction faces that are parallel to the axis; a casing that includes a back, at least two sides, and at least two end blocks; wherein the sides extend away from the back, the blocks are fastened to the sides at edges opposite of the back, and the tube is positioned between the blocks to form a cover to the casing; initiators included between the end blocks and the force reaction faces; a sensor subsystem that detects a threat, wherein the sensor subsystem is coupled to the initiators, and the sensor subsystem generates an initiation signal in response to the detection of the threat; and when the initiators receive the initiation signal, the initiators substantially simultaneously generate a force such that the tube is rotated about the axis to rotationally defeat the threat.
