M. Christophe Duret 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).

  • Absolute angle sensor with a magnetic encoder having non-even spaced reference pulses
    Patent number: 6871554
    Abstract: A device for determining the absolute angular position of a turning device with respect to a fixed structure, including an encoder provided with a main multipolar track and a multipolar track called “top turn”, said top turn track includes M singularities which are distributed angularly so that the top turn signal (C) is arranged so as to define, in conjunction with the signals A and B, the binary sequences which are each representative of an absolute angular position of the encoder. The invention also concerns a steering system for automobiles as well as a bearing including such a device.
