Abstract: An injection member penetrates an elastic septum of a device defining a sealed, empty, sterile chamber in fluid communication with the septum. During penetrating, an annular interface is formed between the septum and the injection member extending axially between a penetration point on an interior surface of the septum in fluid communication with the sterile chamber, and an exterior surface of the septum engaging the injection member. The injection member is de-contaminated by (i) friction between the septum and injection member at the annular interface, and (ii) elongation of the septum at the annular interface. A substance is introduced through the injection member and into the sterile chamber of the device, the injection member is then withdrawn from the septum, the septum reseals itself at the resulting penetration aperture, and the chamber is maintained sterile throughout the foregoing steps.

Title: Procedes et dispositifs de correction d'aberration optique

Abstract: La présente invention concerne des affichages proches de l'il à l'intérieur de dispositifs de tête qui offrent aux utilisateurs, qu'ils présentent ou non une déficience visuelle, de meilleures expériences visuelles, grâce à l'amélioration ou bien à l'augmentation de leur perception visuelle. À moins que l'utilisateur visualise directement l'affichage sans éléments optiques intermédiaires, alors le concepteur doit prendre en compte les aberrations chromatiques ainsi que les autres aberrations. Dans l'état de la technique, le trajet optique est soit complexe du fait des éléments de correction additionnels qui augmentent le poids, le coût et la taille, soit du fait du traitement d'image. Or, les applications en temps réel avec des utilisateurs mobiles requièrent une faible latence pour éviter des effets physiques secondaires. En conséquence, il serait avantageux de prévoir des affichages proches de l'il atténuant ces distorsions et aberrations chromatiques par l'intermédiaire de techniques de traitement électronique basées sur la pré-distorsion en conjugaison avec une optimisation de conception du trajet optique avec un faible poids, un faible volume, une faible complexité et un faible coût. En outre, il serait avantageux d'exploiter des unités de traitement graphique à faible coût et grand public plutôt que des circuits spécifiques à une application.

Abstract: A harvesting header on a vehicle such as a combine harvester includes a mounting assembly comprising left and right float elements each for applying controlled left and right lift forces and arranged to allow upward floating of each end of the header in response to ground contact. Left and right sensors detect the angle of tilt of the header and a control system operates to reduce the left lift force when the left end is raised and to reduce the right lift force when the right end is raised. On a combine harvester this can be done by rotating the face plate of the feeder house in the required direction. In other systems the force generated by the left and right float elements can be directly modified. The changes to the lift force are applied only when the propulsion vehicle is tilted beyond a predetermined angle.

Abstract: An electronic certificate-based payment system comprising a vendor terminal (2), a payment system (1), a client terminal (4), and a logistics terminal (3). The vendor terminal (2) applies to the payment system (1) for issuance of an electronic certificate. The payment system (1) issues the electronic certificate. The client terminal (4) collects the electronic certificate and requests the payment system (1) for a payment amount. The payment system (1) converts the amount to a requested state and notifies the logistics terminal (3) to transfer goods. The logistics terminal (3) instructs movement of the goods to a destination. The payment system (1) transfers the amount in the requested state into a corresponding account when shipment receipt information is received. By means of the electronic certificate-based payment system, a restriction to a specific sales location is removed, and an original transaction mode that relied on the reputation of a third-party platform and centered on an electronic vendor is altered, thus forming a transaction mode centering on goods, and facilitating autonomous and highly efficient circulation of the goods on the internet.

Abstract: La présente invention concerne un récipient étanche fermé inviolable, comprenant un adaptateur de transport de fluide. L'adaptateur crée une communication fluidique stérile entre une source de fluide à l'extérieur du récipient et l'intérieur du récipient lorsque l'adaptateur est ouvert.

Une alternative à l'adaptateur utilise un accessoire d'échantillonnage qui s'insère en mise en prise étanche avec le couvercle qui comprend au moins un septum. L'accouplement de l'accessoire d'échantillonnage avec le couvercle entraîne la pénétration d'objets pointus et tranchants dans l'accessoire dans l'au moins un septum ou le déplacement des bords du septum vers l'intérieur pour former une communication fluidique avec l'intérieur du récipient, tandis que le couvercle reste fermé hermétiquement. D'autres variantes comprennent un accessoire d'échantillonnage rotatif, un récipient doté d'une paroi inférieure déplaçable pour agir comme une seringue et une ampoule étanche de grand volume (par exemple, 1 500 ml) qui utilise également un accessoire d'échantillonnage.
