Times corresponding to the detected transitions are stored and the times that have elapsed between each transition and the previous transition of order 2N, which constitute durations for a complete revolution of a rotating member, are calculated. When the durations thus calculated are stable, a time that has elapsed between a tested transition and the previous transition is calculated, and a characteristic angle of the tested transition is deduced therefrom, this being proportional to a ratio between a time that has elapsed since the previous transition and a stabilized duration for a complete revolution. An index transition is identified and is used to ascertain absolute position of the encoder with respect to the sensor."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Method for detecting an absolute angular position or an absolute angular movement path of a rotating member","description":"A multi-pole annular encoder having 2N poles distributed irregularly is positioned facing a sensor that detects transitions between the poles.
