Abstract: A slat (116) is arranged to co-operate with substantially similar slats (117) for the construction of structures, primarily garden furniture. Each slat defines a substantially C-shaped cross section with a central element (501) and two longitudinal elements (502, 503) attached to the central element. Locking teeth (505) are applied to an external surface (504) of the central element, arranged to radially extend about a connecting hole (506). The connecting hole receives a spindle (507) arranged to securely hold the slats in position. With the spindle loosened, it is possible to re-configure the furniture for different purposes. However, with the spindle held tightly in place, the furniture becomes rigid and suitable for supporting body weight.

Abstract: A system for monitoring the advancement of a needle (1) detects the puncture of the peritoneum and of the entrance into the abdominal cavity at the beginning of a laparoscopic operation. The need of such a system is mostly recognized in re-operation cases and in operations on overweight patients with lots of fat tissue. A sensor (3) capable of measuring vibration during punctures is placed and coupled on any location on the needle (1) and is protected against thermal and/or mechanical interactions. Initially the puncture information is relayed to the user of the system via a visual display such as an oscilloscope (6). A computer (8) with communication capabilities (I/O cards) or other means of processing could be added to the system. With the use of a computer (8) the signal can be processed and transformed to other means of display: colour leds, graphs, an audio indicator (change of tone, volume etc...) or a haptic indicator.

Abstract: L'invention concerne un sélecteur de canaux et un procédé qui permettent d'établir une liaison radio entre un poste central et un poste d'abonné dans un système de radiocommunication comprenant au moins deux canaux de fréquences par lesquels ladite liaison radio peut être établie. Le sélecteur de canaux comprend une mémoire pour stocker les données identifiant au moins lesdits deux canaux de fréquences; une commande de sélection pour sélectionner un canal de fréquence dans ceux listés dans ladite mémoire; et une logique d'acquisition de liaison pour établir une liaison radio sur le canal de fréquence sélectionné par la commande de sélection. La commande de sélection répond à la logique d'acquisition de liaison, lorsque celle-ci est incapable d'établir ladite liaison radio, en sélectionnant un autre canal de fréquence dans ceux listés dans ladite mémoire. Par cette approche, il est possible d'augmenter le nombre de postes d'abonné pouvant être supportés par le système de radiocommunication, puisque si un canal de fréquences est totalement utilisé au moment où une liaison radio entre un poste d'abonné particulier et un poste central est demandée, un autre canal peut être sélectionné pour l'établissement de ladite liaison.

Abstract: Drugs are formulated as unit oral dosage forms by incorporating them into polymeric matrices comprised of hydrophilic polymers that swell upon imbibition of water to a size that is large enough to promote retention of the dosage form in the stomach during the fed mode. The oral formulation is designed for gastric retention and controlled delivery of an incorporated drug into the gastric cavity, and thus administered, the drug is released from the matrix into the gastric fluid by solution diffusion. The swollen polymeric matrix, having achieved sufficient size, remains in the gastric cavity for several hours if administered while the patient is in the fed mode, and remains intact long enough for substantially all of the drug to be released before substantial dissolution of the matrix occurs. The swelling matrix lowers the accessibility of the gastric fluid to the drug and thereby reduces the drug release rate. This process, together with diffusion retardation by selection of specific polymers, polymer molecular weights, and other variables, results in a sustained and controlled delivery rate of the drug to the gastric cavity.

Abstract: Cette invention se rapporte à un échangeur thermique, ou à un composant faisant office d'échangeur thermique dans un dispositif multifonctionnel, fabriqué à partir d'un matériau polymère assurant les échanges thermiques. Ledit échangeur thermique se caractérise par une tendance réduite au claquage du matériau polymère, ledit claquage pouvant résulter d'une tension excessive et entraîner une contamination croisée des deux fluides. Il est possible de mettre en oeuvre deux approches différentes, de manière individuelle ou conjointe, pour réduire la tendance au claquage. La première approche consiste à modifier le matériau polymère de manière à accroître sa résistance au claquage. La seconde approche consiste à utiliser un pont électrique entre les fluides se trouvant des deux côtés de l'échangeur thermique, puis à établir un équilibre électrique entre les deux fluides.
