Abstract: An embodiment of an apparatus for determining the attitude angles of a weapon includes a number of accelerometers for measuring the components of the acceleration of the weapon along the axes of a first reference system integral with weapon; a number of gyroscopes configured in such a way to measure the components of the angular speed of the weapon along the axes of the reference body; and a processing unit configured to compute a number of actual attitude angles of the weapon under dynamic conditions based on the components of the angular speed; determine a number of static attitude angles of the weapon under static conditions of the weapon based on the components of the acceleration; and correct the components of angular speed according to static attitude angles and to the actual attitude angles.

Abstract: An embodiment of an optoelectronic apparatus for assisting an operator in determining the shooting attitude to give to a hand-held grenade launcher so as to strike a moving target including an electronic processing unit configured so as to: measure the pitch angle and the heading angle of the grenade launcher and the distance of the target when the grenade launcher is moved by the operator during the pointing of the moving target, determine position data indicative of the positions of the moving target, determine a future impact time of the grenade on the target on the basis of position data and of data indicative of the ballistics of the grenade, determine a shooting attitude of the target on the basis of the impact time, measure the pitch angle and heading angle indicating the attitude imparted to the grenade launcher by the operator, compute a pitch difference between the shooting pitch angle and the pitch angle measured and a heading difference between the shooting heading angle and the heading angle meas

Abstract: An arrangement of a panoramic video is obtained by applying navigation commands to said panoramic video. The navigation commands are formed either by navigation commands given at will by the user, or by predefined navigation commands associated with said panoramic video. The choice of the type of navigation command used at a given instant is controlled either automatically or by the user. In this way, it is avoided that a user loses the thread of the action while permitting free navigation through a panoramic video.

Abstract: An encoding and a decoding method for transmitting and storing description element(s) of an XML-like document which is an instance of an XML-like schema.

Abstract: The invention relates to a method of searching a predetermined number of objects which are closest to an example, in a hierarchical object structure which is obtained by using a hierarchical object classification method. The proposed method consists of going through the hierarchical structure starting from the root, descending as far as the first node closest to the searched example of which a number of leaves lower than the number of lacking results depend, and then going back up to the brother node of this node which is closest to the searched example, so as to add other results and so on and so forth until said predetermined number is arrived at. Application: MPEG-7 descriptions.

Abstract: The invention relates to a partitioning method of a set of objects which comprises an initialization phase for determining a partition which has an optimal number of classes, and a modification phase of this partition for obtaining a partition whose classes have optimal contents from the point of view of the search for objects. The invention also relates to a multilevel partitioning method of partitioning a set of objects which utilizes such a partitioning method for creating a tree-like structure of objects. The invention finally relates to a search method, for example, of searching a certain number of objects which are closest to an example in the tree-like structure obtained in this manner.
