  • Publication number: 20100253325
    Abstract: The invention relates to a motor vehicle gearbox position detector comprising a sensor (3) designed to cooperate with a moving target (5) connected to a gearbox ratio actuation element so as to provide at least one analogue signal representative of the position of the neutral point of the gearbox, characterized in that it additionally comprises a unit for processing the signal (9) comprising an analogue-to-digital converter designed to convert the analogue signal into a digital output signal (17) so as to provide periodic predefined information corresponding to the position of the neutral point only when, on the one hand, the target (5) is in the neutral point position and, on the other hand, when the sensor (1) is in the normal operating state.

  • Publication number: 20080218746
    Abstract: The invention concerns a method for detecting gas bubbles in a liquid adapted to a device comprising a light source, a light detector and a data controlling and processing unit connected to a client system comprising the following steps: emitting light from the light source, acquiring successive measurements of the light intensity sensed by the light detector and calculating a variation between two successive measurements of said light intensity. In accordance with a first embodiment of the invention, the method further comprises a step which consists in comparing the variation between two successive measurements of light intensity to a threshold S. Advantageously, a warning counter is incremented by a value A when variation between two successive measurements is higher than the threshold S and decremented by a value B in the opposite case. A proportion of bubbles higher than a maximum authorized rate is detected when said warning counter exceeds a warning value C.
