Patent CA-2436493-A1 (CA)
Inventor: LEMIEUX RENE
IPC: B62D55/24
Filed: 2003-08-05
Abstract: A vehicle track includes an endless belt. A plurality of laterally-elongated propulsive lugs and longitudinally-elongated turning lugs extend outwardly from an outer side of the endless belt. The propulsive lugs provide substantially longitudinally facing surfaces that dig into the snow to give the vehicle track propulsion and braking traction.  However, the gripping force of the propulsive lugs impedes the longitudinally-elongated track's ability to pivot about a generally vertical axis as the tracked vehicle turns. The turning lugs include longitudinally-elongated side surfaces that substantially face in the lateral direction of the track. When the tracked vehicle is steered, the fuming lugs form laterally-facing ramps that push the track upwardly away from the snow in response to lateral forces exerted by the snow on the fuming lugs. The resulting upward track movement partially disengages the propulsion and fuming lugs from the snowy to enhance the track's steerability.

Title: Polyarchical data indexing and automatically generated hierarchical data indexing paths
Inventor: COOKE JONATHAN GUY GRENSIDE
IPC: G06F17/30
Filed: 2002-03-01
Abstract: Data indexing using polyarchical indexing codes and automatically generated expansion paths. For a piece of data, an indexing code is received relating to a particular categorization or other indexing parameter. Based upon the indexing code, one or more expansion sets of codes are retrieved and applied to the piece of data. The expansion sets of codes may include indexing codes that relate to hierarchical levels of indexing (80, 82, 84). The expansion sets of codes may also include different expansion paths through the hierarchical levels of indexing. The polyarchical codes may include multiple cross-categorization of the data across the same or different levels of categories (64). They may also include multiple expansion paths in different directions across hierarchical levels of categories or indexing (62).

Abstract: An insulated hot water heater is comprised of an inner casing defining a reservoir in which water is heated.      An outer casing is disposed about the inner casing and spaced therefrom to define an insulating space. Heat insulating material is disposed in the insulating space and extends at least about a circumferential side wall and a top wall of the inner tank. A disc of rigid insulating foam material is disposed between a top wall of the inner casing and a top wall of the outer casing. A method of thermally insulating the hot water heater consists of inverting the water heater and foaming the insulating space with a thermally insulating foam material whereby to achieve optimum foam density in the top portion of the hot water heater between the top wall of the inner casing and the top wall of the outer casing.

Title: Procede de polarisation et circuit attenuateur de distorsions
Inventor: APARIN VLADIMIR
IPC: H03F1/30
Filed: 2002-04-17
Abstract: La présente invention concerne une technique d'annulation sélective de la non-linéarité du 2?nd¿ et du 3?ème¿ ordre d'un transistor. Toute non-linéarité est une fonction de la tension de polarisation d'un transistor. Dans de nombreux cas, cette fonction fait qu'à une tension de polarisation particulière, la non-linéarité devient nulle. L'invention porte ainsi sur un circuit de polarisation qui produit la tension de polarisation optimale pour un transistor dont la non-linéarité demandée est nulle. Mathématiquement, la non-linéarité peut se représenter comme une somme de plusieurs composantes dont certaines sont affectées d'un signe moins. Ces composantes sont proportionnelles aux intensités courant continu du transistor dans le cas où les tensions de polarisation diffèrent de peu. Le circuit de polarisation comporte des transistors de polarisation qui sont des versions à diverses échelles du transistor principal. Chaque transistor de polarisation produit une intensité courant continu représentant l'une des composantes. On combine les intensités en fonction des signes des différentes composantes de façon à former un signal courant continu proportionnel à la non-linéarité choisie. Un circuit à rétroaction, ayant sondé le signal courant continu, produit des tensions de polarisation des transistors de polarisation capable d'annuler de force le signal courant continu. L'une des tensions de polarisation est appliquée au transistor principal, ce qui aboutit à l'annulation de la non-linéarité qui avait été choisie pour lui. Ce système peut se mettre facilement en oeuvre en utilisant la technologie des circuits intégrés de façon que les transistors du circuit de polarisation soient étroitement accordés les uns par rapport aux autres et par rapport au transistor principal. L'effet d'annulation produit par la présente invention s'avère peu sensible aux variations affectant le traitement du transistor et la température de fonctionnement.

IPC: H04L12/56
Filed: 2002-10-15
Abstract: The present invention changes the wireless information service paradigm from a connection-oriented unicast network model to a dynamic content-driven multicast model using a technique called "content routing." The present invention provides a system, method, and medium for routing content (105) through a network from at least one content provider (100) to at least one content consumer (150), wherein at least one of the content consumer (150) or content provider (100) communicate with the network using a wireless device.  The content is routed though the network based on its content. The content is labeled with at least one content descriptor (110). The content descriptor (110) characterizes or otherwise describes the content (105). Interest profiles (125) are received from content consumers (150). Interest profiles (125) from content consumers (150) with a common network access point are aggregated into a single interest profile. Interest profiles (125) can include more than the wireless consumers stated interest, such as for example, a content consumer's geographic location, the capabilities of the wireless terminal, type of service, policy preferences, and the like. Single interest profiles are shared across neighboring network access points to create a content routing table. Content, labeled with at least one descriptor, is routed through the network (140) to content consumers (150) based, in part, on content routing tables created from wireless content consumers' profiles.
