Abstract: The present invention relates to a data transmission system including a data exchange unit; wherein, to transmit a data frame, it passes successively at least through an interface module that is configured to receive said data frame from outside the transmission system; an analysis and filtering module responsible for processing said data frame which is received from the interface module before encapsulation; and an encapsulation module responsible for encapsulating said data frame processed by the analysis and filtering module, wherein two successive modules through which said data frame passes are connected to one another by an interconnection device each including a temporary memory for storing said frame and the read and write accesses to said memory being frequency-independent.

Abstract: Alloy containing between 1% and 20% by weight of Ni, between 1% and 20% by weight of Sn, between 0.5%, 3% by weight of Pb in Cu which represents at least 50% by weight of the alloy; characterized in that the alloy further contains between 0.01% and 5% by weight of P or B alone or in combination. The invention also pertains to a metallic product having enhanced mechanical resistance at intermediate temperatures (300° C. to 700° C.) and excellent machinability. The metallic product of the invention can be advantageously used for the fabrication of connectors, electromechanical, or micromechanical pieces.
