Abstract: The invention relates to a simplified digital wiring system for vehicles. The invention comprises a synchronisation generator (2) which is connected to a plurality of multiplexer modules (1a, 1b, 1b?) via a synchronisation (6) and, at other times, data line. In turn, the aforementioned multiplexer modules (1a, 1b, 1b?) are connected to a plurality of inputs and/or outputs for receiving/transmitting data from/to electroelectronic devices, such that the synchronisation generator selects a multiplexer module so that said module manages the inputs and/or outputs thereof and, in this way, can control the operations of the different electroelectronic devices (13-19). Moreover, the multiplexer modules can be connected to the synchronisation generator (2) in parallel (1a) or in series (1b, 1b?). The invention is advantageous in that the multiplexer modules (1a, 1b, 1b?) are connected using a single synchronisation (6) and data (7) line, thereby simplifying the wiring.

Abstract: The invention relates to split-chamber pressure exchangers. Split-chamber pressure exchangers are characterized in that the pressure exchange chambers and the pistons thereof are split in two. Each fluid passes through the corresponding chamber thereof, such that said fluids cannot be mixed. The cross sections of the chambers can be varied in order to vary the transmitted pressure. The reverse line operation can be established and synchronized using a U-shaped tube with telescopic sides and a fixed base filled with fluid or diametrically opposed curved lines, and multiple arrangements can be used. Split-chamber pressure exchangers can be used as surface or well pumping systems and the pumping fluid used can differ from the fluid to be pumped. Different levels of any material can be exploited at any storage site using a chamber with elastic walls filled with fluid and attached to the bottom. Electric power can be generated by centrifuging the pre-pumped fluid.
