Patent CA-2443079-A1 (CA)
Title: A method and apparatus for transferring data packets in communication networks
Inventor: BERGLUND JAN
IPC: H04N7/24
Filed: 2002-03-25
Abstract: A method and a transcoder for transcoding data communicated between a sender (100) and a receiver (102). Data units (202, 208) comprising information in a first format (F, IF) are received and coded into new data units (208, 210) in a second format (IF, F'), based on a current coding state (302, 502, 706) extracted from a previous coding of data. A new current coding state is extracted each time a data unit (202, 500, 700) is coded. If a received data unit is in an erroneous sequence order, the current coding state is saved and a new pseudo coding state (DS2', ES2', CS2') is eytracted for codng a next received data unit. Eventually received missing data (F2, S4) is coded into the second format (IF, F') based on the saved coding sate, and may then be used as valid data. In this way, delays are minimised and jitter buffers are not necessary, while still maintaining a high quality.

Abstract: A heat exchanger useful for high temperature applications such as EGR cooling and fuel reformer applications comprises a tube bundle made up of a plurality of tubes, each having at least one end expanded to an enlarged polygonal cross-section, and having central portions with a generally smaller cross section. When the tubes are formed into a bundle, the enlarged end portions nest with one another and interstitial spaces are provided between the central portions of the tube. The enlarged end portions are preferably retained by a header ring having a multifaceted inner peripheral sidewall which is adapted to form brazed lap joints with the outward facing surfaces of the peripheral tubes end portions in the tube bundle. In one preferred arrangement, axially aligned enlarged portions are provided intermediate the ends of at least some of the tubes. These enlarged intermediate portions nest with one another and eliminate or reduce the need for baffle plates.

Filed: 2002-04-30
Abstract: The delivery of content across a wireless communication link (25) is based on a mobility state associated with a wireless transceiver (33). The system (1) employs pricing tiers, which represent each subscriber's (40) mobility-based privileges to specific content. That is, a mobile user (40) can be charged a premium to maintain the same quality of service as a stationary user. The impact of mobility is thus felt by the mobile subscriber (40), either by experiencing reduced bandwidth or through higher subscription fees. By limited content delivery, the impact of motion and similar phenomenon on the wireless resources (1) as a whole can be reduced.

Abstract: Une station d'ancrage (10) comprend un ensemble de verrouillage de mât (12) qui se fixe à l'extrémité extérieure d'un mât (M). Un adaptateur (14) qui se connecte à une plate-forme de capteurs (G) se fixe de manière réversible à l'ensemble de verrouillage de mât. Un ensemble isolant (16) se monte sur une surface (D) d'un véhicule (V) à proximité d'une ouverture (O) dans laquelle le mât s'étend et se rentre. Lorsque le mât est rentré, l'adaptateur (14) se fixe à l'ensemble isolant (16) et est dégagé de l'ensemble de verrouillage de mât. Ainsi, la plate-forme de capteurs est fixée à l'ensemble isolant qui protège désormais les capteurs des vibrations produites par le véhicule et de tous les chocs créés par le terrain sur lequel le véhicule se déplace. Cela permet également l'utilisation des capteurs pour la surveillance pendant le déplacement du véhicule. Lorsque le véhicule s'arrête et que le mât est à nouveau sorti, l'adaptateur (14) se refixe à l'ensemble de verrouillage de mât et est dégagé de l'ensemble isolant.
Patent CA-2447179-A1 (CA)
Inventor: XIAO JIAQI
IPC: G01V3/28
Filed: 2003-10-28
Abstract: Induction and other resistivity well logging tools determine formation conductivity at various depths but these measurements contain pronounced errors when the tool is proximate to an inclined underground bed boundary. A method to correct tool measurements includes calculating an expected tool response at a relative dip angle of zero degree and at a particular depth based on an earth model of the underground formation. An expected tool response at the known dip is then calculated. Comparing the calculated zero-dip response with the calculated non-zero-dip response yields the dip effect. A response is also modeled to exclude the non-linearity of the shoulder effect. Comparing the calculated linear response (obtained, e.g. by the Born approximation) with the calculated zero-dip response yields the nonlinear shoulder effect. The nonlinear shoulder effect and/or the dip effect may then be corrected for by subtracting them from the raw or pre-processed measurements.

Title: Horizontal rotating amusement swing
Inventor: BALLMICK CHANDREKA P
IPC: A63G1/20
Filed: 2004-03-10
Abstract: An amusement swing apparatus for children and adults alike and more particularly, a horizontal rotating manually operated swing. It can be conceptualized as two seesaws lapped in the middle at right angles, but instead of the riders going up and down, they remain in a horizontal plane and rotates about the centre point. Where these beams cross at the middle, they are supported on a housing that carries two bearings, one on top of the housing and one at the bottom. This housing is fitted to a vertical shaft that passes through the centre of the lapped beams and allows the housing with the lapped beams to rotate freely around it. The shaft is firmly fixed to the ground or floor surface. Four or six legs, attached to a flange welded to the shaft add support to the structure. These legs spread out evenly around the flange and are fixed to the ground or floor surface. The four outer ends of the beams have seats for persons to sit on. At the top of the centre shaft is a short vertical pin that is placed offset by a flat plate in the shape of a cam. This cam shaped plate is attached to the top of the centre shaft by means of a boss. The boss is welded to the bottom of the larger side of the cam-shaped plate. Fixed on the underside of each of the lapped beams, at the outer ends near to where each person sits, are footrest frames. Directly above these footrests are handle frames that axe hinged to the beams and have a handle for each rider to hold on to with both hands.  These handle frames are free to move forward and backwards. Each handle frames have a short cross pin to which the connecting rods are hinged. The other ends of these connecting rods are hinged to the vertical offset pin with interconnecting short knuckle linkages. These short linkages have two rings at each end that are turned horizontal and vertical. Any one out of the four riders can operate the swing. By grabbing the handles and moving them forward and backward creates a translation force on the frame to allow the rider to start rotate around the centre pivotal point.
