Abstract: A method for automatically proposing an air conflict resolution, the method includes a step of receiving air conflict and air situation data at a time when an air conflict is detected, the method comprising the steps of: determining a conflict category associated with the detected air conflict based on the conflict data; determining a degree of relevance in proposing a resolution to the air conflict according to the category and the air situation; determining one or more types of resolution to be applied to resolve the detected air conflict according to the degree of relevance; determining set of alternative trajectories corresponding to the one or more types of resolution; determining a set of candidate trajectories from among the set of alternative trajectories, a candidate trajectory being an alternative trajectory which does not generate an air conflict; selecting, from among the candidate trajectories, a candidate trajectory which fulfills a selection criterion relating to the operational relevance of th

Abstract: To produce pulses in a cyclically repetitive mode while modifying the production frequency, a counter looped on itself is used. The outputs of this counter are connected to the address inputs of a memory. The signals read in the memory represent pulses to be produced. When it is sought to increase the period of reading the totality of the memory gradually, some of the words of this memory are read for a greater period of time. In the invention, words are chosen for which this addressing will be maintained by comparing the reverse of the reading address with a given value and by deciding, as a function of the result of this comparison, whether the word read at this address must be read for a longer duration or not. It is shown that this circuit is very easy to make and requires but few components. The circuit made can be used particularly in the field of the control of three-phase synchronous motors.
