Abstract: An authorization management system for personal use of a weapon includes a receiving module coupled to the weapon and a transmitting module configured to be worn by a user in proximity to a body of the user. The transmitting module is located in proximity to the ground. The transmitting module is configured to transmit a signal representing at least an identification code data associated to the user via a signal path through a user's body. The receiving module is configured to receive the signal and actuate a safety system of the weapon for allowing the user a usage of the weapon based on the received signal.

Abstract: A heat exchanger (1) for gases, in particular for the exhaust gases of an engine, comprising a bundle of tubes (2) arranged inside a casing (3), intended for the circulation of the gases in order to exchange heat with a coolant, at least one gas tank (6) that can be fitted to one end of the casing (3) and connected to the gas recirculation line, and a particle filter (7) for filtering the exhaust gases, associated with said gas tank (6). Said filter (7) is incorporated into the gas tank (6) and forms a single inseparable part that can be fitted to the casing (3) of the exchanger (1). Preferably, the filter (7) is incorporated into the gas tank (6) by welding. A filter which is fully incorporated into the gas tank in a single part is obtained, which therefore facilitates the assembly thereof to the exchanger casing.

Abstract: A process for manufacturing a foamed laminar product in which the foam is obtained from thermoplastic material and additives. In order to improve the rigidity of the foamed laminar product, reinforcement fiber is added to a mixture of thermoplastic material and additives, so that the reinforcement fiber forms an integral part of the foamed laminate.
