Patents by Inventor Alain Maire

Alain Maire has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Patent number: 8571741
    Abstract: A device for measuring the movement of a self-guiding vehicle, that has an enhanced measuring reliability, in particular during an adhesion loss and independently from the travel profile of the vehicle in terms of slope, turn and slant. To this end, the device for measuring the movement of a self-guiding vehicle includes on board thereof two accelerometers coupled to a movement calculator, wherein each accelerometer includes two measurement axes on which are measured projections of a vehicle acceleration resultant. The four measurement axes of the accelerometers are adjusted so that the calculator provides, from the four projection measures, at least one very accurate longitudinal acceleration value of the vehicle at each point of a route including both slopes and turns.

  • Patent number: 8423234
    Abstract: The invention relates to a device for measuring the movement of a self-guided vehicle, that comprises onboard thereof: at least one accelerometer provided with a measurement axis arranged in the longitudinal direction of a potential main rectilinear movement of the vehicle, a first tachometer provided on an axle upstream from the vehicle in the longitudinal direction, a second tachometer provided on a second axle downstream from the vehicle in the longitudinal direction, wherein measure signals from the accelerometer and from the first and second tachometers are supplied to a computing unit. Accordingly, it is advantageously possible to determine the speed and the position of the vehicle on a vehicle route while taking into account an adhesion loss of at least one of the axles as well as an exact slope and turn effect on a vehicle route that does not remain rectilinear and changes horizontally and/or vertically.
