Abstract: The invention comprises several vehicle parameters transducers (1, 2, 3, 4) associated to respective slave circuits (10, 20, 30, 40) connected by a single, time-shared serial bus (60) with a master slave (50) which, when activated from a digital processing unit (DP), performs a communication with each one of the slave circuits, a bit frame circulating through said serial bus (60) according to a transmission protocol, without error correction, formed by a series of bit packets, each one with information from a corresponding slave circuit and separated by a short time interval, which information is stored in said master circuit (50) from where it is acquired by the (DP) through a parallel bus (70).

Abstract: The connector (11) is made up of electroinsulator supports (1, 2) carriers of at least one pair of terminals (3, 4) capable of coupling to a plug said terminals (3, 4), being in a coupling position for said electroinsulator supports (1, 2), electrically joined to each other establishing a channel (5) for the passing of electrical energy towards said power load (10), the method and system being made up of a connection (15) between a point (23) of said channel (5) near to the load (10) and after the connector (11), whose connection passes through the connector (11), in order to detect a voltage (V2) and/or intensity in the second point (23), which is compared with the voltage (V1) of supply, and in the event of a sudden change being observed, said supply is cut off.

Abstract: Method and system for canceling echoes and noises in environments with variable acoustic conditions and high feedback, such as the interior of an automotive vehicle, permitting audible communication between the occupants, comprising one/several microphone/s (1) for a speech signal (5) and A/D, D/A converters, amplification and filtering means generating an electric signal (13) reproduced as an acoustic signal (7) by a speaker (3), and an echo canceller (15) using said signal (13) and an electric signal (10) from the microphone integrating the feedback of said signal (7), another speech signal (5) and noise (9) seized by the microphone (1), the system (15) being applied to eliminating said feedback, the proposed method and system providing an additional filtering of an electric output signal (11) of the canceling device (15), after treatment of said signal, comprising a time variant filter that suppresses the residual acoustic echo not cancelled by the system (15) and the noise seized by said microphone/s (1).
