Abstract
(EN)
An encoder system includes a configurable detector array, wherein the configurable detector array includes a plurality of detectors. The encoder system may also include a memory operable to store a partition map that defines a state for each of the plurality of detectors. The encoder system may also include an emitter operable to generate a flux modulated by a motion object, wherein the configurable detector array is operable to receive the flux and generate respective current outputs for each of the detectors in response to the flux. In an embodiment, the current outputs from detectors having a same state are grouped together. The encoder system may also include one or more current duplicators to duplicate the current outputs from detectors having one state to group with the current outputs from detectors having a different state. The encoder system may also adjust weights of the current outputs.

La présente invention concerne un système de codage qui comprend un réseau de détecteurs configurable, le réseau de détecteurs configurable comprenant une pluralité de détecteurs. Le système de codage peut comprendre en outre une mémoire utilisable pour enregistrer une carte de partition qui définit un état pour chaque détecteur de la pluralité de détecteurs. Le système de codage peut comprendre en outre un émetteur utilisable pour générer un flux modulé par un objet mobile, le réseau de détecteurs configurable étant utilisable pour recevoir le flux et générer des sorties de courant respectives pour chacun des détecteurs en réponse au flux. Dans un mode de réalisation, les sorties de courant provenant de détecteurs ayant un même état sont regroupées ensemble. Le système de codage peut également comprendre un ou plusieurs duplicateurs de courant pour dupliquer les sorties de courant provenant de détecteurs ayant un état pour regrouper les sorties de courant provenant de détecteurs ayant un état différent. Le système de codage peut également ajuster les pondérations des sorties de courant.
