Patent CA-2231872-A1 (CA)
Inventor: KOIVUNIEMI PEKKA
IPC: G06F12/0866
Filed: 1996-09-13
Abstract: In fault-tolerant systems it is known to write data into two separate disk drives. It is also known to duplex computers so that when one computer fails, the other computer can continue operating. In such a system, the active unit usually controls both disk drives. It is also known to cache in the main memory of the computer the most recently used areas in the disk drive, since it is likely that these areas (e.g. directories) must be read again soon. A problem occurs when using duplexed computers each of which is to be provided with a possibility of using the disk drive (14, 24) while the operation is expedited by caching in the main memories of the computers (10, 20). If one computer modifies the data in the disk drive, the other computer is not necessarily aware of this, but it uses the outdated data in its memory. According to the invention, the computer (10) desiring to control the disk drive (14) reserves it for itself. If the reservation is successful, a disk task is performed. If the data in the disk drive (14) is changed, the other computer (20) is informed of this change and it erases from its memory the cached data corresponding to the changed data.

Title: Patient-specific immunoadsorbents for extracorporal apheresis and methods for their preparation
Inventor: RAMLOW WOLFGANG
IPC: A61K35/14
Filed: 1996-10-03
Abstract: The invention relates to the production of multiple-application patientspecific immunoadsorbents which can be used for extracorporal apheresis in patients suffering from disorders caused by dysregulation of the immune system. Conventional methods are used to isolate the immune complexes from the patient's blood and appropriate methods are applied to separate the immune complexes into antigens and antibodies. The antigens and antibodies thus reactivated are coupled individually or as a mixture covalently to suitable carriers which are used as immunoadsorbents for the patient from whom the immune complexes originate. This facilitates production of specific immunoadsorbents even for patients suffering from rare auto-immune diseases.

Patent CA-2252668-A1 (CA)
Inventor: BERENS WERNER
IPC: B29C48/12
Filed: 1998-02-12
Abstract: Profiled sections (1), in particular extruded seals made of elastic material, can be designed and produced economically and in such a way that they have absolute storage stability and low coefficients of friction and are suitable for a wide variety of uses, in the profiled sections (1) are made of a non-lacquer-repelling material and after having left the extruder (12) and before entering the fused salt bath (16) are coated with a lubricating lacquer (7) applied to the uncured surface (5). The lubricating lacquer (7) is then cured in the fused salt bath (16) without there being a need for a separate curing section or similar. An advantage of this method is that it not only evenly coats the profiled sections with lubricating lacquer (7) but also prevents the information of air bubbles or the like, thereby yielding a consistently even coating (6).

Patent CA-2259568-A1 (CA)
Inventor: TJALKENS TJALLING JAN
IPC: H03M7/42
Filed: 1997-07-08
Abstract: Known systems use two probability signals for coding an input signal into an output signal and for decoding said output signal into the input signal. In a first memory field two probability signals are stored, and in a second memory field two other probability signals are stored, and in response to a further received symbol processor means adapt the probability signals. Such a system needs a giant memory capacity, which can be reduced by combining probability signals into a first combination signal to be stored in the first memory field and by combining further probability signals into a second combination signal to be stored in the second memory field, and by converting a third combination signal into at least one probability signal just before (de)coding takes place.
Patent CA-2260195-A1 (CA)
Inventor: HOPKINS T ERIC
IPC: G06T1/00
Filed: 1997-06-27
Abstract: An image acquisition system for machine vision systems decouples image acquisition from the transmission of the image to a host processor by using a programmable imager controller to selectively disable and enable the transmission of data to the host and by using a system of buffers to temporarily store image data pending allocation of memory. This enables the image acquisition system to acquire images asynchronously and to change the exposure parameters on a frame-by-frame basis without the latency associated with the allocation of memory for storage of the acquired image. The system architecture of the invention further permits interruption and resumption of image acquisition with minimal likelihood of missing data. Data throughput is further enhanced by transmitting to the host only that data corresponding to the region of interest within the image and discarding the data from outside of the region of interest at the camera stage.

Filed: 1997-05-22
Abstract: L'invention concerne un dispositif de transport comportant, sur le tronçon de transport (1), un embranchement (6) avec un aiguillage (7). Cet aiguillage présente un élément d'aiguillage (8) pivotant qui, dans une position, est situé dans le tronçon de transport (1) et dans une autre position, relie ce premier tronçon de transport (1) à un deuxième tronçon de transport (10). Monté en aval de l'embranchement (6), un organe de retenue (11) peut être placé dans la trajectoire de déplacement des organes de transport (2) transportés le long du premier tronçon de transport (1). Cet organe de retenue (11) permet d'arrêter les organes de transport (2) arrivant à l'embranchement (6), afin de laisser suffisamment de place pour la commutation de l'élément d'aiguillage (8). Les organes de transport (2) sont indépendants les uns des autres, ce qui permet, au choix et selon les besoins, soit de déplacer les organes de transport (2) arrivant, le long du premier tronçon de transport (1), soit de les dévier sur le deuxième tronçon de transport (10).
Patent CA-2261030-A1 (CA)
Title: Method for altering cable semiconductive layer
Inventor: GUILBERT CURTIS ROY
IPC: H02G15/188
Filed: 1996-11-21
Abstract: A method of altering a portion of the semiconductive layer of an electric power cable, to increase its resistance so as to render it electrically insulative. The semiconductive layer is loaded with carbon powder which forms chains to provide conductive pathways through the layer. By introducing an intercalant into the semiconductive layer, which causes the layer to swell, the conductive pathways are interrupted and the material is rendered insulative ( > 104 .OMEGA.-cm). The intercalant may be a polymerizable material with a curing agent which is cured in situ, i.e., without removing the semiconductive layer from the cable. By this method, flashover to the semiconductive layer at a cable splice or termination may be prevented without requiring tedious removal of the exposed portion of the semiconductive layer.  The method is usable with both strippable and coextruded semiconductive layers.

Title: Catheter air drying and storage
Inventor: CATHCART JAY A
IPC: A61B50/30
Filed: 1999-04-01
Abstract: This invention relates to the air drying and storage of a catheter more particularly a intermittent urinary catheter. It is known in intermittent urinary catheterization that when a sterile catheter has been used, it is either disposed of, or washed, air dried and reused. Urinary tract infections are very common, this partly is do to the insertion of the foreign device into the individuals urethra and bladder, bacteria is carried in and takes hold. In this invention the air drying and storage of a catheter is enhanced by suspending it vertically in free air, so no physical contact is made with the tip of the catheter (the tip is the part of the catheter that is inserted into the individuals urethra and bladder). So the introduction to bacteria and/or foreign materials is greatly reduced.
