Patent ID: 7139309

Claim:
A process for transmission of information between at least two devices according to which elements of information which are succeeding each other in a time sequence are passed along over an electrical or optical support, said elements of information being made of a packet of bits forming messages which comprise one or more data and/or addresses of the devices for which these data are intended, said process causing no interference with existing Universal Asynchronous Receiver/Transmitter (UART) based communication systems of the devices, and allowing nevertheless an increase of the amount of various distinct messages which a system is able to convey, the process comprising: generating a serial message coded by means of a time sequence of binary transitions called bits; reducing the time length of all bits in the message by changing the bits into shorter bits called “reduced bits”, in order to insert additional bits whose half duration falls at the moment in time where binary transitions between unchanged bits occurred when no additional bits are inserted keeping the half duration point of all reduced data bits to the same place as they were in an unchanged message keeping the total duration of the serial message containing the additional bits identical to the total length of the unchanged message, the duration of data bits being reduced by 50% and the duration of start and stop bits being reduced by 25%.
