A connection device for connecting a first piece of electronic equipment to a second piece of electronic equipment, the device comprising two Ethernet type interfaces that are linked together by an up line and a down line and that are arranged for each of them to be linked to a respective one of the pieces of equipment and to transmit data in differential mode, two power supply modules, each associated with a respective one of the pieces of equipment and wired in common mode between the up and down lines in order to transmit a power supply carrier signal in alternating current, and two secondary transmission modules, each associated with a respective one of the power supply modules and arranged to enable data to be transmitted by modulating the power supply carrier signal.

Device for connecting two pieces of equipment via an Ethernet link, and a docking station for such a piece of equipment

Assembly for the electronic processing of data, comprising a central module and peripheral modules linked to the central module by electrical power supply and data links, the modules comprising: a processing unit, a memory, an input/output unit and an isolation of the power and data links; the central module furthermore comprising an electrical power supply unit for the peripheral modules, a common startup unit shared by the modules, and a star communication interface with the peripheral modules; each peripheral module furthermore comprising a serial link interface to the communication interface of the central module.

Assembly for the electronic processing of data with mutualized resources

A bidirectional gateway with enhanced security level between a high-security communication network and a low-security communication network. The return pathway from the low-security network to the high-security network comprises a low-speed link. The physical layer of the low-speed link differs from the physical layers involved in the high-security network and the low-security network. The low-speed link having a linking layer according to a protocol differing from the protocols used on the linking layers used on the high-security network and the low-security network. The linking layer of the low-speed link has an authentication protocol to guarantee the data's origin.
