Abstract: Damage mitigating apparatus comprises in one embodiment a damage mitigating aerial vehicle that has sensors for detecting flight related characteristics and a communication unit for commanding activation of parachute deploying apparatus and of a lift generator deactivation unit following determination of a flight failure. In one embodiment, an aerial vehicle transmits a critical failure alarm signal to an unmanned aircraft traffic management system (UTM) following detection of the failure, and the UTM transmits a warning signal to neighboring aerial vehicles that are predicted to be in a vicinity of the descent path of the failed aerial vehicle to avoid collision with the failed aerial vehicle. The damage mitigating apparatus facilitates performance of a damage mitigating operation.

Abstract: Damage mitigating apparatus comprises totally extending hollow tubes, and projectiles attached to undeployed fabric and formed with a tube-receivable rod. Pressurized gas which is generated upon triggering of a gas generator flows through the tubes to propel the projection and to cause performance of at damage mitigating operation. In one embodiment, a damage mitigating aerial vehicle comprises sensors for detecting flight related characteristics and a communication unit for commanding activation of parachute deploying apparatus and of a lift generator deactivation unit following determination of a flight failure. In one embodiment, an aerial vehicle transmits a critical failure alarm signal to an unmanned aircraft traffic management system (UTM) station following detection of to failure, and the UTM elation transmits a warning signal to neighboring aerial vehicles that are predicted to be in a vicinity of the descent path of the failed aerial vehicle to avoid collision with the failed aerial vehicle.

Abstract: A system for homing and recharging an unmanned vehicle comprises a plurality of homing layers operative along the radius of an imaginary circle that has the homing target at its center, each homing layer consisting of a sub-system provided with location means of increasing accuracy relative to that of a sub-system that operates along said radius farther away, from the center of said circle.

Abstract: The present invention relates to a parachute deploying apparatus, comprising: a) a manifold with which is releasably coupled a single vessel within which pressurized gas is generated; b) a gas generator which cooperates with said vessel; c) a plurality of hollow tubes which extend obliquely and upwardly from, and are in communication with, said manifold; and d) a plurality of projectiles, each of which formed with a rod that is receivable in a corresponding tube and to each of which is connected a cord that is also connected to a corresponding portion of an undeployed parachute, wherein the pressurized gas which is generated upon triggering of said gas generator is flowable through each of said tubes to propel said plurality of projectiles in different directions and to cause said parachute to become deployed.

Abstract: A centering system for positioning an Unmanned Autonomous Vehicle (UAV) is provided with two or more supporting extremities rigidly connected thereto, comprising a pair of displaceable positioning elements provided with surfaces sloped relative to each other, which create trapping areas such that when said positioning elements are caused to move one relative to the other, said two or more supporting extremities are caused to be trapped in said trapping areas.

Abstract: A payload exchange facilitating connector module, comprises: a) a structure secured to a payload; b) a locking member operatively connected to said structure! c) a locking initiating element that is settable in force transmitting relation with said locking member! and d) two guiders configured to urge an interface element of two different external positioning components, respectively, to undergo linear and non-rotatable relative motion exclusively with respect to said structure, until said locking initiating element is set in force transmitting relation with said locking member to cause said locking member to become coupled with a dedicated element of a first of said positioning components, or following decoupling of said locking member from said dedicated element to facilitate payload exchange.
