A method of transmitting information making it possible to monitor the operation of an internal combustion engine, includes the steps of:

Method of transmitting information relating to the operation of an internal combustion engine

An angular position sensor includes a rotating part () which creates a variable magnetic flux, a fixed part () for supporting two probes () each having an output current, the first () of the probes having an output current having discontinuities when the magnetic flux passes through zero, the second () of the probes being subjected to a second magnetic flux, shifted by 90&#xb0; relative to the first flux and having an output current that is a continuous function of the magnetic flux, and a device () for adding the currents from the two probes. The range of variation of the current from the first probe () is slightly larger than the range of variation of the current from the second probe (). The sensor is applicable to engine camshafts.

A device for determining the angular position and rotation speed of a rotary member. The inventive device includes a sensor having a fixed part and a rotary part which is linked to the rotary member. The rotary part bears a magnetic flux generator, while the fixed part includes: a first probe which generates an electric signal having two different levels as a function of the angular position of the rotary member; and a second probe which is angularly offset in relation to the first probe and which generates an electric signal as a one-way function of the angular position of the rotary member for each segment of revolution corresponding to a level of the electric signal generated by the first probe. Analysis elements having elements for unequivocally defining the angular position of the rotary member, and for calculating the rotation speed of the rotary member are provided.
