Abstract: Cette invention se rapporte à une unité rehausseur de signal de portable d'utilisateur à faible coût, qui permet d'étendre la couverture de services de communications sans fil à un utilisateur dans une zone souhaitée de couverture limitée. Ce rehaussement accepte une augmentation des niveaux de puissance du signal, pour permettre une utilisation des communications sans fil dans un lieu où les signaux cellulaires d'origine sont faibles ou peu fiables, par exemple dans un environnement restreint ou dans un local de petite taille. A cet effet, un signal de station de base est rehaussé par un dispositif amplificateur bidirectionnel (BDA), qui reçoit un signal de station de base, amplifie la puissance du signal et retransmet le signal amplifié sur un premier trajet de signal à un utilisateur proche. L'amplificateur bidirectionnel reçoit également un signal d'utilisateur, amplifie la puissance du signal et retransmet le signal amplifié à la station de base sur un second trajet de signal séparé. Des antennes polarisées doubles peuvent recevoir et transmettre les signaux respectifs à des polarisations opposées, pour augmenter l'isolation des signaux.

Inventor: TEN CEBRIAN ANDREA
IPC: H04L12/851
Filed: 2004-04-21
Abstract: The invention relates to a method of classifying individual frames (OSI level 2 packets) into different priority levels according to the contents thereof.  The inventive method is based on the application of a set of rules and sub-rules which are used to analyse the contents of each frame and assign a priority level to the frame accordingly. In this way, the invention enables the low-cost construction of systems which provide a quality of service or classes of service according to any element of the packet, i.e. origin, destination, level three data flow, higher level applications, any type of higher level priority classification (such as IP ToS) and, above all, according to any type of standard or proprietary priority protocol. The invention can also be used to design different priority hierarchies such that it is possible to assign one or other set of priorities depending on the situation (e.g. one hierarchy for TCP packets and a different hierarchy for UDP packets).

Title: Temperature control for multi-vessel reaction apparatus
Inventor: CHU DANIEL Y M
IPC: C12M1/38
Filed: 2000-07-11
Abstract: Temperature control in a rectangular array of reaction vessels such as a thermal cycler such as is used for PCR procedures is achieved by sue of a temperature block that is in contact with a combination of Peltier effect thermoelectric modules and wire heating elements embedded along the edges of the block. The elements can be energized in such a manner as to achieve a constant temperature throughout the array or a temperature gradient. Further control over the temperature and prevention of condensation in the individual reaction vessels is achieved by the use of a glass (or other transparent material) plate positioned above the vessels, with an electrically conductive coating on the upper surface of the glass plate to provide resistance heating.

Abstract: A seal assembly for effecting a fluid tight seal between a pipe and an opening in the wall of a structure, particularly a relatively thin-walled structure made of a rigid plastic, fiberglass, or of metal, for example. The seal assembly generally includes a seal ring and an annular nut. The seal ring includes a relatively rigid fastener component having external threads, and a relatively resilient sealing component joined to the fastener component and including a first sealing projection for providing a compressive seal between the seal ring and one side of the structure wall, and a second annular sealing projection for providing a compressive seal between the seal ring and the outer surface of a pipe inserted through the seal ring. The seal ring is inserted through the opening in the structure, and the annular nut is threaded onto the external threads of the fastener component and into engagement with a first side of the wall to thereby compress the first sealing projection against the opposite, second side of the wall. Thereafter, a pipe is inserted through the seal ring to compress the second sealing projection between the outer surface of the pipe and the seal ring.

Patent CA-2556854-A1 (CA)
Inventor: CARINE DAVID SHAUN
IPC: B60N2/48
Filed: 2005-03-11
Abstract: A deformable, polypropylene-moulding lining (11), is provided in a head rest. It has a crosspiece (12), clipped (14) to the head support (5) and right and left deformable wings (15, 16). These are longer than the support wings (5, 6) of the head part (4), extending past distal edges (17) of the support wings. The deformable wings are spaced inwards from the support wings, with voids (18) defined between them. The deformable wings are divided into two in their forwards extent by a living hinge (19) into a front portion (20) and a rear portion (21). The living hinge is positioned just inside the distal edges of the shell wings. The injection moulded lining has its own foam materiel lining (22), the whole being covered with upholstery (23). The result of the arrangement is that if an occupant's head H impacts the lining in side impact of the vehicle equipped with the seat, the relevant lining wing will be pressed against the shell wing. This involves energy absorbing (maximum acceleration limiting) deformation of not only the foam material, but also of the lining wing and to a less extent of the shell wing. With the lining wing deformation (24), the front portion (20) of the lining wing pivots forwards about the shell edge (17), from a position swept back with respect to the shell wing to a position generally in line with the compressed inner portion of the lining.
