Patent CA-2252720-A1 (CA)
Title: Procede et dispositif pour embrouillage video compatible en compression
Inventor: RYAN JOHN O
IPC: H04N7/169
Filed: 1997-05-29
Abstract: L'invention concerne des techniques d'embrouillage et de désembrouillage qui, à l'inverse de beaucoup de systèmes d'embrouillage classiques, sont compatibles avec toutes les formes possibles de compression des signaux. La technique d'embrouillage repose sur le principe d'une distorsion spatiale appliquée localement aux pixels d'une image video, et autres, l'objectif étant de déplacer les pixels par rapport à leur emplacement normal. La plupart des systèmes de compression reposent sur le principe selon lequel il existe une bonne corrélation dans l'image, moyennant quoi toute petite partie, c'est-à-dire tout pixel, d'une image ressemble beaucoup aux autres parties, ou pixels proches. Etant donné que la technique considérée consiste à appliquer localement la distorsion spatiale sans décorrélation de l'image et sans réaménagement des pixels dans l'image, les positions respectives des pixels avant l'application de la technique d'embrouillage restent les mêmes après embrouillage. La technique de désembrouillage complémentaire rétablit l'emplacement normal des pixels déplacés localement, en vue de rendre à l'image vidéo son état initial non embrouillé.

Title: Members having a multiaxially oriented coating of thermotropic liquid crystalline polymer and methods and apparatus for producing such members
Inventor: LUSIGNEA RICHARD W
IPC: B29C48/10
Filed: 1997-01-24
Abstract: Coatings of multiaxially oriented Thermotropic Liquid Crystalline Polymer (TLCP) are provided to elongated members. Suitable members include glass rods, glass fibers, pipes, beams, and other oval or polygonal members having an essentially regular cross section. Members of ceramic, plastic, or metal can also be coated. This extrusion is performed using a die having inner and outer mandrels capable of rotating in opposite directions. Concentricity between inner and outer mandrels of the die is maintained to assure uniform coating thickness. In order to produce a high level of multiaxial orientation at lower die rotational speeds, the die design may include spiraling feed zones on one or both facing surfaces of the inner and outer mandrels. The application of the multiaxially oriented coating provides superior impermeability to water vapor and oxygen, and increased strength to the elongated member in the axial direction.

Title: Fitness and body posture exercise apparatus
Inventor: PRSALA JAN J P
IPC: A63B23/02
Filed: 1999-05-25
Abstract: The invention relates to an exercise device capable of entirely supporting a person's head, back and buttocks (seat) through the use of a carriage (located and moving on the inclined semi-circular tracks) and the feet through the use of the foot rest. The semi-circular tracks and the foot rest are mounted on vertical posts which are connected to a solid rectangular frame. The movement of the carriage is made possible by four small wheels fastened at the bottom of the carriage, which roll in corresponding partially covered grooves of the semi-circular tracks.      The body weight of a person is used as a resistance for the exercises which can be varied by changing the inclination of the tracks.     When a person is properly positioned in the device, the person's body moves the carriage up the tracks by the interaction between the torso and the legs. The flexed legs extend and the head and back resist the leg action by pressing against the carriage. On the way down, the legs (by flexing) control and stop the movement of the body and carriage. Thus a beneficial exercise for the legs, buttocks, pelvis, lower back, upper back and neck is generated. This exercise may improve the person's body posture.      The device is further equipped with two pairs of firm handles on both front and rear posts, with another set of handles, cables and pulleys on the back end of the tracks and with similar pair of handles on the sides of the carriage. All these handles serve for the various arm exercises executed with or without the assistance of the rest of the body.

Title: Method and apparatus providing for router redundancy of non internet protocols using the virtual router redundancy protocol
Inventor: MEEHAN TOM
IPC: H04L12/56
Filed: 1999-11-25
Abstract: One or more nodes configured with data communication protocol suites other than TCP/IP, and for which a default routes election protocol such as VRRP is not available, forwards non TCP/IP traffic destined to nodes on other network to the VRRP master virtual router. A non TCP/IP based node, given a statically configured Network layer address for a next hop routes, resolves the Network layer address to a VRRP based MAC layer address for the next hop routes, if the next hop router has VRRP enabled and is the master virtual routes for TCP/IP traffic. The non TCP/IP node caches the VRRP based MAC address for use in forwarding non TCP/IP traffic to an available next hop routes. Thereafter, the non TCP/IP node forwards traffic destined to nodes on other networks to the VRRP master virtual router. If the master virtual router becomes unavailable to forward TCP/IP based traffic, it transitions to become the new backup virtual router, while the backup virtual router transitions to become the new master virtual router responsible for forwarding TCP/IP based traffic. The new master virtual router shares the same VRRP based MAC address. Therefore, the non TCP/IP based node, having cached the VRRP based MAC address of the next hop router, forwards traffic destined to nodes on other networks to the new master virtual router. This removes the need for intervention or reconfiguration of the non TCP/IP based node for continued routing of non TCP/IP traffic transmitted therefrom in the event that the router identified therein by the statically configured Network layer address for a next hop router becomes unavailable.
