Patent CA-2210358-A1 (CA)
Title: Cutter blade for hair clippers
Inventor: ALTAMORE NICOLO
IPC: B26B19/22
Filed: 1997-07-15
Abstract: A clipper for cutting hair strands includes a blade set which has a stationary blade having a plurality of stationary blade teeth arranged in a row so that hair strands enter between adjacent stationary teeth as the blade set moves through the hair strands. The stationary blade teeth having angled side cutting edges and tips, and the side cutting edges of adjacent teeth form roots where they intersect.      A moving blade has a plurality of blade teeth which are also arranged in a row. The blade teeth of the moving blade complement the stationary blade teeth and pass across the stationary blade teeth in use to cut some of the hair strands. The blade teeth of the moving blade are relatively short, and preferably have tips which are flat. The blade teeth of the moving blade are separated by blade-like edge surfaces which are oriented in the direction of movement of the moving blade and are capable of cutting some of the hair strands which enter between the stationary blade teeth. The knife-like blade edges form a first line which is between a second line formed by said stationary blade teeth roots and a third line formed by the stationary blade teeth tips.

Patent CA-2211918-A1 (CA)
Title: Method and apparatus for performing multiwavelength photoplethysmography
Inventor: POLOGE JONAS A
IPC: A61B5/00
Filed: 1997-07-30
Abstract: A photoplethysmographic measurement device that utilizes wavelength division multiplexing is provided.  Signals from multiple light emitters are combined into a single multiplexed light signal in a test unit before being delivered to a physically separated probe head attached to a test subject. The probe then causes the single multiplexed signal to be transmitted through a tissue under test on the test subject, after which it is processed to determine a blood analyte level of the test subject. By combining the light signals into a single multiplexed signal before delivering the signals to the probe, a single light guide, such as a single optical fiber, can be used to deliver the signals to the probe, thereby reducing system implementation cost and increasing the flexibility of the probe cable. In addition, the invention allows the signals from the light emitters to be directed into the test subject from a single point source, which can significantly increase measurement accuracy.
Patent CA-2213629-A1 (CA)
Title: Maintaining invalidation information in tiled image representations
Inventor: HAMBURG MARK
IPC: G06T11/80
Filed: 1997-08-22
Abstract: A method and apparatus for tracking invalidation information in tiled pixel image representations that combines the concept of an invalidation rectangle with the concept of invalid tile flags. A pixel is considered as being possibly invalid if and only if it lies within the invalidation rectangle and the tile containing that pixel is flagged as invalid. In accordance with the present invention, to invalidate an area, the implementing program generates an invalidation rectangle so that it bounds the area and the previous invalidation rectangle (if not empty), and also sets the invalid tile flags in the tiles overlapping that area.  To validate an area A within an image, the inventive method performs the following steps: Define area B as the intersection of the area A to be validated with the invalidation rectangle. If area B is empty, the process is done: no pixels in area A are invalid. If area B is not empty, then determine which tiles intersect area B. For each tile intersecting area B, if the tile is marked as valid, and more tiles need to be processed, get the next tile that intersects area B. If all tiles have been processed, the process is done. If a tile is marked invalid, then define area C as the intersection of the area covered by the tile with the invalidation rectangle. Then validate area C by recalculating all of the pixels in area C, and clear the invalid flag for that tile. If more tiles need to be processed, the next tile is fetched. Otherwise, the process is done: no pixels in any area C - and hence in area A - are invalid.

Title: Controlled release biodegradable nanoparticles containing insulin
Inventor: RAMTOOLA ZEBUNNISSA
IPC: A61K47/48
Filed: 1996-04-02
Abstract: A controlled release pharmaceutical formulation comprises nanoparticles formed of a biodegradable polycyanoacrylate polymer in which insulin is entrapped, the insulin being complexed to the polycyanoacrylate. These particles are capable of releasing bioactive insulin in vivo at a slower release rate than nanoparticles in which the insulin is free. The formulation may comprise a mixture of nanoparticles in which the insulin is free and nanoparticles in which it is complexed, so as to obtain the desired release profile. The nanoparticles have a preferred loading of 15-25 % w/v insulin and a preferred size of 100-400 nm. Administration may be oral or parenteral, and for oral administration, an enteric coating may be provided to target release to the small intestine. Complexing of the insulin is achieved by the polymerisation of cyanoacrylate monomer in the presence of insulin at a low pH, preferably at pH=2.

Title: Transmission de donnees par paquets dans les systemes de communication a acces multiple par difference de code
Inventor: CIDECIYAN ROY DARON
IPC: H04J13/00
Filed: 1995-06-14
Abstract: L'invention se rapporte à un système divisé en une couche physique (20), une couche liaison de données et une couche réseau (24). La couche liaison de données est elle-même divisée en trois parties, à savoir: commande de liaison de données (DLC) (23), et deux parties de commande d'accès au support (MAC) (21 et 22). La couche DLC (23) est chargée de l'établissement, de la libération et du maintien des liaisons. La partie MAC inférieure (21) peut exister dans des situations multiples, tandis que la partie MAC supérieure (22) est unique. Physiquement, les deux parties MAC (21 et 22) sont séparées du côté réseau parce que la partie MAC supérieure réside dans un régisseur de réseau de radiotransmission (RNC), tandis que la partie inférieure existe dans chaque station de base. L'entité de service de radiotransmission par paquets sans connexion (CLPS) (25.1) assure le service de radiotransmission par paquets auprès de l'usager mobile et, du côté réseau, l'entité CLPS (25.2) assure tous les services requis pour l'enregistrement et l'authentification des usagers mobiles, avec attribution et gestion de leurs identificateurs de connexion virtuelle (VCI) et interfaçage avec le réseau  de transmission de données par paquets. Les entités CLPS (25.1 et 25.2) utilisent des administrateurs de liaison logique (LLA) (26.x) pour acheminer initialement les messages via une voie de commande spécialisée ordinaire (DCCH) (27.x) vers leurs entités homologues. Une fois la station mobile rattachée à la voie de transmission par paquets (PRCH), tous les messages échangés entre les entités CLPS (25.x) ainsi que les paquets de données d'usager sont systématiquement acheminés via la voie PRCH (28.x) respective. Dans ce cas, les paquets de commande et les paquets de données d'usager sont transmis par l'intermédiaire de la DLC (29.x) à l'entité de commande de radiocommunication par paquets (PR) (30.x). Les paquets sont fragmentés et protégés au moyen d'un code de protection contre les erreurs (par exemple, code complet (BC)), par une unité correspondante (31.x) pour la détection des erreurs de transmission du côté réception. Ils sont codés au moyen d'un code à convolution, entrelacés par l'entité (32.x), et transmis sur la voie de données physique (PDCH) (33). Du côté réception, les fragments sont reconstruits à partir des échantillons reçus, réassemblés en paquets, et acheminés vers l'entité CLPS (25.2) de destination. Lorsque le décodeur (31.2) détecte la réception d'un fragment de paquet erroné, une demande automatique de répétition (ARQ) prévue au niveau de la commande de transmission par paquets demande la retransmission.
