Abstract: La présente invention, qui concerne un système et procédé rendant plus facile l'examen pathologique in-vivo d'une lésion tissulaire (23a), porte notamment sur un système informatique auquel sont couplés une caméra (19) permettant de produire une image macroscopique numérique de la lésion ainsi qu'un imageur (22). L'imageur, qui est commandé par le système informatique, comporte une optique capable de balayer la lésion pour donner des images qui représentent des zones microscopiques de la lésion et qui donnent suffisamment d'informations pour l'examen pathologique de la lésion. Le système informatique produit des informations permettant de localiser dans l'image macroscopique de la lésion les emplacement d'où on a obtenu par balayage optique des images de la lésion. Le système informatique assure également le stockage des données dans une structure de fichier électronique qui contient au moins une image macroscopique et les informations de localisation.

Patent CA-2320279-A1 (CA)
Title: Implantable device with digital waveform telemetry
Inventor: PRUTCHI DAVID
IPC: A61N1/372
Filed: 1999-02-05
Abstract: A technique for acquiring and accessing information from a medical implantable device is provided. Analog waveforms of interest are sensed and processed by signal acquisition circuitry. Analog parameters of interest are applied to selector switches which are controlled by a logic circuit. The logic circuit is also coupled to a A/D converter for converting the analog signals to digital values. The digital values are stored in dedicated registers and are available for telemetry to an external device upon receipt of a request or prompt signal. When a digitized value is accessed and telemetered, the control logic circuit changes the conductive state of the selector switches to apply the corresponding analog signal to the A/D converter. The resulting digital value is applied to the corresponding register to refresh the accessed and telemetered value. The technique permits the external device to request and configure the implanted device to send only digitized values of interest. The technique also makes efficient use of the A/D converter, which consumes energy only as needed to refresh the memory when digital values are accessed and telemetered.
Patent CA-2323389-A1 (CA)
Inventor: CENTERS STEVEN D
IPC: F17C13/04
Filed: 2000-10-17
Abstract: A multi-stage blowdown valve is provided that uses a single control signal to simultaneously decompress the interstage and the second stage in a compressor system. The valve uses a series of sliding spools located linearly within a single bore to either prevent or allow fluid communication between two isolated passageways each having an inlet port and a discharge port. The valve, when used as a two stage blowdown valve in a multi-stage compressor system, can prevent compressor failure from occurring by ensuring that both the interstage and the second stages are decompressed, not only the interstage.

Title: In-line web separator
Inventor: MUSHABEN THOMAS G
IPC: B65H35/02
Filed: 1999-05-20
Abstract: The present invention is directed to a method and apparatus for in-line separation of a plurality of laminated webs (10a-10i) of polymer film and no n- woven web to compensate for the increased width due to stretching in the cro ss- machine direction (CD). Due to the stretching in the cross-machine direction , typically by interdigital rolling or tentering, the width of the individual webs (10a-10i) is increased. To compensate for the increase in width, the apparatus and method of the present invention is employed to provide for in- line separation of the narrow webs (10a-10i). The apparatus of the present invention may allow for simplicity in threading the device, due to the abili ty to automatically thread individual turning bars (16a-16i and 18a-18i) by moving the turning bars across the undeflected path of the web (10a-10i).</S DOAB>
