Abstract: L'invention porte sur un procédé d'optimisation d'un dispositif de pompage cardiaque mécanique consistant à moduler le système circulatoire du patient qui va recevoir le dispositif de pompage cardiaque mécanique et à identifier un mode de fonctionnement du coeur natif auquel va répondre le dispositif. Le modèle sert à déterminer le volume sanguin nécessaire que le dispositif doit éjecter et une estimation initiale de la puissance que nécessite le dispositif de pompage cardiaque mécanique de manière à fournir le volume sanguin éjecté nécessaire. Le volume sanguin éjecté ainsi obtenu est évalué avec les données provenant du modèle, après quoi l'estimation de la puissance requise est mise à jour. Les étapes précitées sont réitérées jusqu'à ce que la puissance nécessaire à l'obtention du volume sanguin éjecté requis soit identifiée. On détermine d'éventuelles variations de la puissance et de la vitesse de pompage permettant au dispositif de pompage cardiaque mécanique de fournir le volume nécessaire, puis on sélectionne la variation qui correspond le mieux aux contraintes physiologiques du patient et qui réduit au minimum la puissance requise par le dispositif de pompage cardiaque mécanique. Ces étapes sont réitérées jusqu'à ce que le dispositif de pompage cardiaque mécanique soit optimisé de manière à pouvoir s'adapter à chaque mode de fonctionnement souhaité du coeur natif.

Title: Transverse flux induction heating of conductive strip
Inventor: ROSS NICHOLAS V
IPC: H05B6/44
Filed: 2002-03-20
Abstract: In transverse flux induction heating of electrically cnductive strip (16), conductors (10a, 10b, 12a, 12b) that cross the strip width (14) are stacked, or connected, such that a multiple of the induced current flows across the strip width (14) as compared to that which flows along the strip edges (18).  Conductors (10a, 10b, 12a, 12b) across the width (14) of the strip (16) and conductors (12d, 12e) along the edges (18) of the strip (16) are connected in series to insure that th e current which flows in the conductors is everywhere the same. In the case of two stacked cross conductors (12, 12b), this gives an (IxI)R heating of four times the heating across the strip width (14) as compared to that along the strip edges (18).
Patent CA-2445417-A1 (CA)
Title: A wall structure for use in a furnace or the similar and a method for its construction
Inventor: RUUD ANDERS
IPC: F27B13/02
Filed: 2002-04-24
Abstract: The present invention concerns a wall structure and a method for constructing such an anchored wall structure. The wall structure is designed for use in a furnace or the similar, where the structure is exposed to cyclical thermal load. The structure consists of a row of individual elements which are placed in the longitudinal direction of the structure and are arranged in one or more courses, one resting on the other. The individual elements may consist of bricks of refractory material and the wall structure may also be provided with internal flue gas ducts. The wall structure is also designed to be able to compensate for longitudinal changes and any vertical changes as a consequence of cyclical thermal load. The wall structure's longitudinal changes are compensated for in a connection (2) arranged at least one end of the wall structure. The structure's individual elements are fixed to each other in the horizontal direction by means of mutually interacting contact elements. This produces a structure which remains stable after repeated thermal cycles, and costs related to restoration and stoppages can be reduced.

Patent CA-2446843-A1 (CA)
Inventor: BAUR AL J C
IPC: A01G25/16
Filed: 2003-10-27
Abstract: The most efficient water irrigation systems today for gardens and/or fields typically use dripping systems that release drops of water at certain distance intervals for example for about 30-60 minutes per day (for example every 30-100 cm of the pipe there is dropper that releases typically 2 litters of water per hour) and are typically controlled by timers that start or stop the water in the main pipes. However, although this is in general more efficient than systems that do not use droppers, this can still be far from optimal since it does not take into account different needs for each area, depending for example on the individual needs of each plant, heterogeneity of soil type, different amount of Sun or shade in each part of the garden or field, different number of plants in each area, etc. In other words, irrigation systems based on pipes with droppers, typically controlled only with a timer, which are the most common form of irrigation used today, suffer from one very basic weakness, which is that they have no feedback, so they are in essence working blindly. On the other hand, normal humidity sensors and automatic faucets are expensive, and also many of the known methods for humidity sensing suffer from various limitations, such as for example limited range of response, sensitivity to changes in the salinity of the ground, sensitivity to changes in temperature of the ground, etc. The present invention tries to solve the above problems by providing much cheaper humidity sensors that are still quite reliable and also much cheaper automatic faucets, so that preferably each plant or (preferably small) group of plants can be automatically watered by an individual set of moisture sensor and automatic faucet. The attainment of cheap automatic faucets is preferably done by using at the end nodes of the system low water pressure, so that much less force is needed to open and close the local waterway, and then either using much simpler electrical valves that do not require engines, or circumventing the need for electrical valves altogether, by using mechanical sensors that control a mechanical valve or directly exert pressure on a flexible pipe, as explained below. One of the most interesting variations is mechanical sensors based on a bi-material of two or more materials which expand differently when they become wet, thus converting the difference of the expansion into convenient movement. Another possible variation, instead of mechanical sensors and valves, is to use some chemical control that takes advantage of the behavioral tendency of the water itself, such as for example using a preferably synthetic material that tends to behave like a normal root preferably at the edge of each side channel, so that the "root"  counter-balances the water supply and reaches equilibrium with it when the soil becomes wet enough, based preferably on asymmetric capillary materials.

Title: Apparatus and method for protecting data recorded on a storage medium
Inventor: LEUNG TONY KWOK
IPC: G06F21/78
Filed: 2001-12-27
Abstract: A controller for protecting data on a data storage medium is disclosed. A  single physical data storage device is divided into a protected data space, a virtual data space and an unprotected data space in an installation mode.  Subsequently, the protected and unprotected data space are presented as two separate physical data storage devices and the existence of virtual data space is concealed. The two data storage devices are respectively represented as having capacity equal to that of the protected and unprotected data space only. A set of protected data (which may include software and data) is initially installed in the protected data space. During use, data transmitted to the controller for recording in the data storage space is recorded only in the virtual data space. Data may be read from either the protected data space or the virtual data space, depending on whether the virtual data space contains newer data. In one embodiment, the contents of the virtual data space are discarded at the beginning of each session of the computing system in which the controller is installed. In another embodiment, the virtual data space is discarded only when the controller is instructed to do so and the contents of the virtual data space may be made permanent by copying them to the protected data space. The protected data space and virtual data space may be located on different data storage devices. The controller may also receive read data and write data requests for an unprotected dta space, which may be used to record data permanently, independent of the protected and virtual data spaces.

Patent CA-2470419-A1 (CA)
Title: Growth factor modified protein matrices for tissue engineering
Inventor: JEN ANNA
IPC: C12N5/071
Filed: 2002-12-18
Abstract: Proteins are incorporated into protein or polysaccharide matrices for use in tissue repair, regeneration and/or remodeling and/or drug delivery. The proteins can be incorporated so that they are released by degradation of the matrix, by enzymatic action and/or diffusion. As demonstrated by the examples, one method is to bind heparin to the matrix by either covalent or non-covalent methods, to form a heparin-matrix. The heparin then non-covalently binds heparin-binding growth factors to the protein matrix. Alternatively, a fusion protein can be constructed which contains a crosslinking region such as a factor XIIIa substrate and the native protein sequence. Incorporation of degradable linkages between the matrix and the bioactive factors can be particularly useful when long-term drug delivery is desired, for example in the case of nerve regeneration, where it is desirable to vary the rate of drug release spatially as a function of regeneration, e.g. rapidly near the living tissue interface and more slowly farther into the injury zone. Additional benefits include the lower total drug dose within the delivery system, and spatial regulation of release which permits a greater percentage of the drug to be released at the time of greatest cellular activity.
