Abstract: The parallel electronic architecture comprises a plurality of processor units connected to a communication bus and each adapted to execute one or more predefined tasks automatically. Each processor unit is configured so that each of its tasks is associated with a header, each processor unit is adapted to communicate with the other processor units using the following protocol: sending on the bus a message including a header characterizing a function, and possibly a frame consisting of one or more words, and each processor unit is adapted to decode each header on the bus and, as a function of the value of said header, either to ignore the message on the bus or to execute the task associated with the header of said message.

Abstract: The invention concerns a method for measuring distance between a first object (1) and a second object (2) which consists in: a) emitting an infrared wave radiation (3) from an emitter (4) fixed on the first object (1), said radiation (3) being emitted towards said second object (2); and b) detecting the return of said radiation after it has been reflected by said second object (2) on a receiver (5) fixed on said first object (1) proximate to said emitter (4). The inventive method is characterized in that it consists in: 1/gradually varying the power of the infrared radiation emitted by said emitter (1) until it reaches a detection power (Ps) corresponding to the power of the wave emitted as from which the radiation reflected by said second object is detected by said receiver; and 2/calculating the distance (D) between said first object (1) and said second object (2) from the value of said detection power, by establishing an equating correlation between said distance (D) and said detection power.
