Abstract: La présente invention concerne un système optique de détection et de suivi de mouvements oculaires d'un individu. Elle consiste essentiellement à intégrer directement des photorécepteurs, de préférence des photodiodes, ainsi qu'un circuit intégré autonome avec processeur dans une lentille de contact. La variation du signal fourni par les photorécepteurs (tension ou courant) permet non seulement de détecter la fermeture de la paupière mais les mouvements de l'œil.

Abstract: A system and method for assigning users to a particular sub band in a given time slot in a NOMA system, where whichever pair of users corresponds to the smallest "candidate pair user throughput deviation value", reflecting the aggregate of the respective difference between the average throughput across all users (K) and the known throughput of each of the two users under consideration ( k 1 k 2 ), and each user attributed to a sub-band other than said selected sub-band. User pairs for consideration may consider all possible pairs, or may be limited to candidate pairs satisfying together, or comprising one or both users who satisfy a criterion such as channel gain, distance to a target, throughput or a combination of some or all of these factors. The power allocated to each sub-band may be attributed by a waterfilling algorithm.

Abstract: A mechanism is presented for attributing users to one or more of a plurality of sub-bands in a multiple access communications system, in which in an initial assignment phase, a first user is selected for a sub band, for example on the basis of a user priority. Users having complementary channel gains to that of the first user are identified, and then a second sub-band user maximizing a performance metric reflecting the achieved throughput, and/or fairness across users, is selected to accompany the first user on that sub-band. The initial assignment phase may terminate once all users have been assigned to a sub-band once. After the first phase is complete, the first user for each sub- band may be the user whose achieved total throughput is furthest from a target throughput defined for that user, wherein each user is assigned to the remaining sub-band to which no first user is currently attributed offering the highest channel gain for that user. Mechanisms for determining user priority, making provisional and definitive power allocations, and performance metrics are proposed.

Abstract: La présente invention propose un procédé d'extraction de données rapide et fiable pour extraire des données d'une base de données tatouées (3) selon un mécanisme de tatouage réversible. Le procédé selon l'invention consiste à obtenir, à partir d'une première requête d'extraction reçue d'un terminal client (1), une deuxième requête d'extraction (R2) pour extraire des données tatouées et une troisième requête (R3) appliquée aux données extraites après avoir été détatouées. En présence dans la première requête d'extraction de conditions de sélection initiales portant sur des attributs tatoués, celles-ci sont incluses dans la deuxième requête après avoir été transformées. En présence dans la première requête d'extraction (R1), de fonctions d'agrégation portant sur un attribut tatoué d'extraction, celles-ci sont incluses sans modification dans la troisième requête (R3) de manière à fournir au terminal client (1) un résultat en réponse à la première requête d'extraction (R1).

Abstract: La présente invention propose un procédé et dispositif associé pour insérer des tuples dans une base de données tatouées sans avoir à détatouer l'intégralité ou une partie de la base de données avant d'insérer chaque tuple. Pour cela, l'invention consiste à stocker dans des métadonnées de tatouage, le type des groupe ou classe dans lesquels les tuples de la base de données ont été répartis lors du tatouage de la base de données. Pour chaque type de groupes ou classes, sont également stockés dans les métadonnées de tatouage une règle définissant une modification de la valeur d'au moins un attribut sur lequel porte le tatouage, en fonction d'un paramètre de force d'insertion. Chaque tuple à insérer est tatoué en appliquant la règle de modification en fonction du groupe auquel le tuple appartient. En raison de la règle utilisée, l'insertion du tuple tatoué ne modifie pas le type de groupe auquel il appartient.
