Patent CA-2273777-A1 (CA)
Title: Orthopedic exerciser
Inventor: FOUCAULT ANDRE
IPC: A63B21/008
Filed: 1999-06-08
Abstract: An orthopedic apparatus for rehabilitation or healing of a knee or the muscles of a leg. The apparatus has a dynamic adjustment mechanism allowing the execution of exercise of different degrees of tension without running the risk of injuring the knee by applying unnecessary or excessive amount of tension on the knee. The dynamic adjustment mechanism is designed to keep the eccentricity of the rotational axes of the leg support member and the leg nil. The orthopedic apparatus may also include a resistance or assistance mechanism for adjusting different degrees of tension during extension and flexion of the leg in order to gain either range of movement or strength. This specially designed mechanism provides a linear type resistance or assistance, which is unvariable during the whole range of movement. This particular resistance, applied on the plantar foot, reproduces normal bio-mechanical stress on the lower limb. The exerciser may further include a blocking mechanism for allowing instant pause and prevents reversal of the movement during the exercise. Finally, the exerciser may still include a static adjustment mechanism for adjusting the leg support member to a predetermined length.

Patent CA-2277750-A1 (CA)
Inventor: PATEL SARVAR
IPC: G09C1/00
Filed: 1999-07-20
Abstract: In the method for transferring sensitive information using unsecured communication, a first party receives a public key of a second party, produces an encryption result by performing keyed encryption on at least a first random number using the public key, and transfers the encryption result to the second party over an unsecured communication channel. The second party decrypts this encryption result to obtain the first random number. Authorizing information is then transferred from the first party to the second party over a first encrypted and authenticated communication channel established using the first random number.      Sensitive information is further transferred from the second party to the first party over a second encrypted and authenticated communication channel established using the first random number if the second party accepts the authorizing information. Numerous applications exist for the system and method, including the wireless industry wherein the first party is a mobile and the second party is a network.

Abstract: Members of the collagen family are ligands for the discoidin domain receptor tyrosine kinases, DDR1 and DDR2. Collagen directly interacts with the extracellular domains and evokes tyrosine phosphorylation of DDRs in a time and concentration dependent manner. Collagen activation of DDR1 induced phosphorylation of a docking site for the Shc phosphotyrosine binding domain.  Therefore, isolated complexes are described comprising (a) a discoidin domain receptor tyrosine kinase or a part thereof, and a collagen or a part thereof;  or (b) a discoidin domain receptor tyrosine kinase or a part thereof and Shc or PTB binding domain of Shc or a protein containing a PDZ domain or a PDZ  domain. Compositions, methods, and uses are also described based on the interaction of DDRs with collagens.

Title: Method of assigning and selecting radio channel
Inventor: SUZUKI YASUNORI
IPC: H04W16/00
Filed: 1998-12-24
Abstract: A method of assigning a plurality of radio channels to realize a radio mobile communication system in which a plurality of radio channels are simultaneously used in each of a plurality of zones (1-7) that form an area (8) where radio channels are repeatedly reused. At least one of the radio channels is assigned for preferential use in each zone, while the other channels are assigned for use in any adjacent zones. A mobile station (10) selects a first radio channel at a frequency (f1) that has been assigned to a visited zone (1). The mobile station then detects unused radio channels at different frequencies (f2-f7) assigned to adjacent zones to select one as a second channel, informs the base station in the visited zone (1) of the selected channels, and uses the radio channels to establish the connection to the base station of the visited zone (1).

Title: Method and apparatus for traffic flow control in data switches
Inventor: LYON NORMAN A
IPC: H04L47/32
Filed: 1999-12-22
Abstract: Method and apparatus for traffic flow control in data switches are disclosed. Emission and loss priorities of cells to be switched are translated into a single discard priority, referred to as a bandwidth priority, which has consistent meaning across different emission priorities. This translation allows simultaneous consideration of loss and emission priority in determining which cells to discard when a switch becomes congested with cell traffic. Such consideration alleviates problems that can arise if cell discard decisions are based solely on either loss priority or emission priority. The invention is particularly useful for Asynchronous Transfer Mode (ATM) switches.

Patent CA-2306803-A1 (CA)
Inventor: LE-NGOC THO
IPC: H04B7/005
Filed: 1998-10-14
Abstract: L'invention concerne une technique de maintien d'une qualité de transmission prédéfinie dans un réseau en zone urbaine (MAN). Chacun des réseaux locaux est couplé à un routeur correspondant. Chaque routeur est couplé à un ou à plusieurs émetteurs récepteurs permettant l'interconnexion des routeurs par des liaisons sans fil. Chaque routeur stocke une table représentative de la topologie du MAN et reçoit des indices détectés représentatifs de la qualité des liaisons sans fil et représentatifs des charges de trafic du réseau. Le routeur adapte la manière de transmission et la voie de transmission selon les indices. Ainsi, le MAN est hautement efficace, en terme de coût, de consommation d'énergie et d'utilisation de largeur de bande. Par exemple, une intensité d'un signal reçu par une liaison de transmission sans fil est contrôlée périodiquement afin de maintenir l'intensité à l'intérieur d'une gamme prédéfinie par ajustement de la puissance de transmission. De plus, un taux d'erreurs pour les données reçues par la liaison est contrôlé. Si l'intensité du signal reçu reste inférieure à la gamme prédéfinie malgré l'ajustement de la puissance de transmission à un niveau maximal permissible, et si le taux d'erreurs approche une limite prédéfinie, une ou plusieurs techniques sont utilisées sélectivement afin de réduire le taux d'erreur tout en maintenant un débit suffisamment élevé du réseau. Les techniques adaptatives comprennent le changement du débit de données, du niveau de modulation, du codage de correction d'erreurs et de l'étalement du spectre. De plus, une voie de données est sélectionnée de préférence selon un algorithme Open-Shortest-Path-First, bien qu'une ou plusieurs voies alternatives peuvent être sélectionnées pour transmettre au moins une partie des données.

Filed: 1998-12-17
Abstract: Electrical cable, in particular for medium- or high-voltage power transmission or distribution, having a metal shield and a semiconductive water-blocking expanded layer. This layer exerts three main functions, the first one is to elastically and uniformly absorb radial forces of expansion and contraction of the cable coating layers due to thermal cycles of the cable during use, thus preventing deformations or breakages in the metal shield, the second one is to ensure electrical continuity between the cable core and the metal shield, the third one is to effectively avoid penetration and propagation of moisture and/or water along the cable core due, e.g., to possible ruptures in the metal shield. The third function is obtained by including in the expanded layer a water-swellable material.
