Abstract: Methods and system for providing information selected from a large set of digital content to at least one user. One such method comprises receiving user context information associated with the at least one user and identifying or generating, using at least one processor executing stored program instructions, a first concept in a semantic network, the first concept representing at least a portion of the user context information.

Abstract: Methods and system for providing information selected from a large set of digital content to a user. Techniques include receiving user context information associated with the user and identifying or generating a first concept in a semantic network, the first concept representing at least a portion of the user context information. The method further comprises obtaining at least one concept, including a second concept, semantically relevant to the first concept at least in part, by synthesizing the second concept based on the first concept and at least one other concept in the semantic network; and providing information to the user, wherein the information is selected by using the first concept and the at least one obtained concept semantically relevant to the first concept, wherein the first concept in a semantic network is represented by a data structure storing any data associated with a node in the semantic network.

Abstract: Methods and system of searching for content in a target set of content based on a reference set of content, a reference semantic network representing knowledge associated with the reference set of content, and a target semantic network representing knowledge associated with the target set of content. Techniques include receiving a user-specified search query, obtaining at least one concept semantically relevant to the user-specified search query by using the target semantic network and the reference semantic network, constructing a second query by augmenting the first search query with one or more terms associated with the at least one obtained concept; providing, to the at least one user, content associated with search results obtained based on searching the target set of content by using the second query, wherein any concept in the semantic network is represented by a data structure storing data associated with a node in the semantic network.

Abstract: The present invention relates to priming device for the explosive charge of a sub-munition scattered by a carrier, of the type incorporating a firing pin onto which a deployable drag ribbon has been attached, a primer able to be driven by a motor organ and a detonating primer to ignite the explosive charge. This device also comprises self-destruction means for the sub-munition operating after a predetermined delay, such means being activated by the extraction of a self-destruction lock. It is characterized in that the self-destruction lock is integral with the drag ribbon and is therefore extracted by the ribbon during its deployment.

Abstract: A system for attaching a priming system onto the body of a grenade, including a support integrally fastened to the grenade body and incorporating a thin cylindrical wall whose upper edge is crimped onto the priming system.

Abstract: A priming system for the explosive charge of a sub-munition carried on board a carrier comprises a main firing pin, a primer tube operative to move from a safety position to an armed position, at least two devices to lock the primer tube in the safety position before the sub-munition is ejected, and a self-destruct mechanism operative to destroy the sub-munition after a predetermined delay. A first one of the locking devices is formed of a cam operative to move from a cam safety position, in which it forms a limit stop preventing the primer tube from passing freely into an armed position, to a retracted position in which it allows free passage of the primer tube. The cam carries an auxiliary firing pin to ignite a delay cord of the self-destruct mechanism. A second one of the locking devices engage the primer tube by the percussion tip of the firing pin to hold the primer tube in a safety position.

Abstract: An initiation device includes a primer-container system placed inside a casing box able to move from a safety position to an armed position through the action of a motor. The system is immobilized in its security position by at least one lock that is released by a shape memory actuator when the surrounding temperature rises above a given value.

Abstract: A priming and self-destruct system for a munition having its own rotational movement about a longitudinal axis includes a trigger mounted to pivot about an axis parallel to the rotational axis of the munition under the effect of centrifugal force and against the action of a return spring. The self-destruct system also has a retention device for a secondary firing pin having its own spring in the armed position that is controlled by the trigger when the system is rotating about the axis of the munition. In the event of a malfunction, the secondary firing pin is released by the trigger when the rotation ceases, i.e., when the munition comes to rest on the ground. At that point and without delay, the secondary firing pin pierces the priming system and initiates the munition.
