Abstract: A cable is provided containing one or o polymeric elements for reduction of crosstalk. The cable includes a plurality of unshielded twisted pairs, each of which is an insulated conductor pair twisted around one another, each having a different lay length. A jacket encloses the plurality of unshielded twisted pairs, where an unshielded twisted pair, has the longest lay length among the plurality of unshielded twisted pairs is positioned within the center of the jacket such that an axis of the twisted pairs that has the longest lay length substantially coincides with the central longitudinal axis of the cable. A plurality of bumper elements are disposed within the jacket in the interstices between said plurality of unshielded twisted pairs, where the bumper elements are profiled polymer structures.

Abstract: A cable has at least a first layer of twisted pairs, having a combination of unshielded twisted pairs, and shielded twisted pairs as well as a second layer of twisted pairs, also having a combination of unshielded twisted pairs, and shielded twisted pairs.

Abstract: A synthetic antenna sonar system, includes: a sonar provided with emission elements and reception elements, the reception elements including a composite physical antenna having N transducers, the sonar being located on a mobile carrier; an inertial unit arranged on the carrier and suitable for measuring instantaneous position and orientation informations of the carrier; a common clock supplying a temporal signal enabling the synchronization of both the inertial unit and the sonar; elements for determining the instantaneous speed of the carrier, the determined speed feeding the inertial unit to correct the drift thereof; and micronavigation elements enabling an image of the seafloor to be obtained through formation of the synthetic antenna channels from K sonar operation recurrences, considering that the physical antenna movement during the carrier displacement is fully known from the informations measured by the inertial unit.

Abstract: A sonar system includes at least one transmitter and one flexible antenna including a plurality of sections articulated one after the other, each section being provided with at least one acoustic receiver. The system is equipped with positioning elements making it possible to determine the instantaneous position of each of the receivers, and calculation elements making it possible to reconstruct an image of the seabed by taking account of the instantaneous micromovements of each of the receivers.

Abstract: A method and kit for draining a flexible container holding a product having a viscosity of between 10 Pa·s and 200 000 Pa·s. The method includes using a flexible container (3); optionally, moving the container (3) to be drained to a drainage site; ensuring the viscous product (2) can flow from container (3) through at least one outlet (9); exerting a pressure on at least one defined area of container (3) using a pressurizing device which preferably includes at least one pressure member (5) and/or a pressure fluid to maintain container (3) in an inflated or partially-inflated state; and removing the pressure once the container has been drained. The drainage kit includes the viscous product (silicon mastic), a flexible container (3) and a draining device including at least one pressure member and/or pressure fluid.

Abstract: Frontal sonar for observing the seafloor, characterized in that it includes: elements for insonifying a seafloor area divided into M sectors, able to perform a characteristic insonification of each sector of the area during an operation recurrence of the sonar; and receiving elements including a physical antenna consisting of an array of K transducers, the antenna being lacunar and thus ambiguous, so that it defines N image lobes, and in that each of the characteristically insonified sector is associated with a single image lobe defined by the antenna, so that the antenna ambiguity is removed.
