Abstract: A system for the assembly and connection of electronic circuits formed on a plurality of substrates or boards (9) of identical size is described. Each board (9) is mounted in a respective module (M) between two elements (7, 8) of resilient, electrically-­insulating material. The terminals of each board (9) are connected to one or more multicore ribbon cables (14) clamped between the resilient elements (7, 8).
The modules (M) are arranged next to each other in sequence and are clamped by means of tie bolts (6) so that the resilient elements (7, 8) are com­pressed to a predetermined extent. The pack of modules (M) thus formed is disposed in a housing (1, 2, 3), preferably of metal, carrying at least one multipole electrical connector (4) to which at least some of the cables (14) are connected so that the circuits carried by the boards (9) can be connected to external devices and/or circuits.

Abstract: Pour détecter le cliquetis d'un moteur à allumage par étincelles, on transforme les vibrations détectées en un emplacement du moteur proche des chambres de combustion en un signal électrique, avec un coefficient d'amplifica­tion réglable. On isole, dans le signal électrique, l'éner­gie dans au moins une bande de fréquence haute et une bande de fréquence basse de cliquetis et dans une bande de fré­quence de bruit de fond, plus basse que ladite fréquence haute, au cours de fenêtres temporelles synchronisées avec le cycle de fonctionnement du moteur, on commande le coef­ficient d'amplification en fonction de la puissance du signal dans la bande de fréquence de bruit de fond, et on détecte la présence de cliquetis par comparaison entre le niveau de puissance dans la bande de bruit de fond et le niveau de puissance résultant d'une sélection entre les bandes de cliquetis ou d'une combinaison entre ces bandes.

Abstract: The device includes two channels (A, B) for detecting and processing the signal provided by an accelerometric sensor (S) operating in two frequency bands in which peaks indicative of pinking (knocking) may occur. In each combustion phase, a third channel (C) also connected to the sensor (S) provides a signal representative of the noise component of the signal from the sensor (S) in a frequency band in which the peaks do not occur.
The signals provided by the first and second channels (A, B) are integrated and then compared with a reference signal generated in dependence on the noise component detected cylinder by cylinder. The device thus enables pinking to be detected cylinder by cylinder.

Abstract: The system includes sensors (w) which provide signals indicative of the rate of rotation of at least one monitored wheel of the motor vehicle and electrically-controlled fluid actuators (4-9) for increasing and reducing the braking pressure applied to the braking elements of the vehicle. An electronic processing and control unit (30) connected to the sensors(W) and is arranged to pilot the actuators (4-9) in conditions of incipient locking of the wheels so as to bring about one or more cycles of anti-lock braking. In each of these cycles, the unit (10) causes in succession:
a controlled reduction of the braking pressure when the at least one monitored wheel is in a condition of incipient locking,
the holding of the pressure at a constant value until the acceleration of the monitored wheel exceeds a minimum positive threshold, and
the increase of the braking pressure again.
During the stage in which the braking pressure is increased again in each cycle after the first, the electronic unit (10) causes in particular:
an initial pressure increase of an amount calculated on the basis of the total increase in the previous cycle and the durations of the last and penultimate periods of controlled reduction of the braking pressure, and
a subsequent, slower increase in the braking pressure.

Abstract: The sensor comprises a body (1) formed by first and second elements (2, 3) of which at least one (2) has a cavity (4), the elements being sealed together to form a chamber (12). The chamber contains an electrically-conductive liquid (14) which fills it almost completely so as to form a bubble (15). At least one main electrode (6) and at least one pair of auxiliary electrodes (5, 9; 7, 10) extend into the chamber (12) through the body (1) and are accessible on the exterior thereof, so that any variation in the inclination of the body relative to at least one predetermined direction causes a movement of the bubble (15) and a corresponding variation in the electrical resistance measurable between each auxiliary electrode and the main electrode. The electrodes are constituted by strips of electrically-conductive material deposited by screen printing on at least one of the said elements by the thick film deposition method.

Abstract: The device allows the monitoring and diagnosis of the functioning of a system comprising a plurality of electrical sensors (3, 4) which produce two-level signals indicative of the condition of members which control the running of the engine and/or of respective monitored parameters or ranges, and an electronic monitoring and control unit (5) with a microprocessor (6), connected at input to the sensors (3, 4) and at output actuators (8) for causing the engine to stop and restart. The diagnostic device also includes interrogation means (6) for carrying out a succession of sequential cyclical scans of the outputs of at least some of the sensors (3,4), and for generating, at each scan, a serial signal (A) comprising a plurality of two-level signal portions, each indicative of the level of signal produced at the output of a respective sensor (3,4). A signalling device (2) is electrically connectible to the interrogation means (6) to convert the portions of the serial signal (A) into corresponding perceptible signals and permit the functioning of the stop-start device to the minitored and diagnosed.
