Title: A motor driven sampling apparatus for material collection
Inventor: HARRIS JOEL S
IPC: G01N1/08
Filed: 2003-10-03
Abstract: An apparatus to excise a sample of material and temporarily store sample has a hollow clamshell casing with a blended grip under which is a tubular sample sleeve extends downwards from the base of the grip. Within the casing an electric motor is housed which drives, via juxtaposed spur gears, the sample sleeve in a rotational manner. The end of the sample sleeve, distal from the clamshell casing, forms a cutting edge circumscribing a circular region. An ejection rod slides reciprocally within the sample sleeve between a stowed position and an expulsion position.  When the ejection rod moves from the stowed position to the expulsion position it will extend past the cutting edge and expel any material sample contained within the sample sleeve. A user cuts a sample from a source material resting on a pliable substrate, using the cutting edge of the sample sleeve when the ejection rod is in the stowed position. A sample is cut when the cutting blade contacts the source material while gentle downward pressure is applied. The thumb activates the electric drive which rotates the cutting sleeve. Once the source material has been cut it is simultaneously extracted and lodged within the tubular sample sleeve. The extracted sample remains lodged in the hollow of the sample sleeve until the user extends the ejection rod through the sample sleeve to the expulsion position to eject the sample of source material. The automatic return of the eject rod is comprised of a compression spring that biases the ejection shaft which holds the ejection rod in the retracted and stowed positions.

Patent CA-2476319-A1 (CA)
Inventor: BUDA PAUL R
IPC: G05B19/05
Filed: 2003-04-11
Abstract: High-speed programmable logic controller (PLC) signal processing is accomplished using a programmable signal processing arrangement that is capable of altering characteristics of signal processing in response to one or more signal processing coefficients. According to an example embodiment of the present invention, a PLC-based arrangement includes a PLC controller and a signal processing arrangement that oversamples and processes a signal at a frequency that is greater than a maximum input-process-output scan rate of the PLC controller. In one implementation, the signal processing arrangement is programmable with complex high-speed signal processing parameters that can be downloaded, for example, via the Internet in response to an end-user request.  With these approaches, signal sampling and processing is achieved with a PLC-based system at a rate that can be much higher than previously-available signal processing rates with PLC controllers.

Title: Moniteur d'ecg portable et procede de detection de fibrillation auriculaire
Inventor: LE DANG V
IPC: A61B5/363
Filed: 2003-06-03
Abstract: L'invention concerne un appareil et un procédé de détection de fibrillation auriculaire au moyen de la surveillance des intervalles R-R d'un patient à complexes QRS. Des rapports de l'intervalle R-R actuel sont transformés en intervalles R-R précédents. De nombreuses moyennes mobiles sont extraites des résultats des rapports. Les rapports sont comparés à un seuil de validation et si le rapport particulier est à l'intérieur d'une gamme sélectionnée, une moyenne mobile est calculée par inclusion de l'intervalle R-R présent. Si le rapport est à l'extérieur de la gamme, une moyenne mobile est calculée sans inclure l'intervalle R-R actuel. Les moyennes mobiles sont combinées et la moyenne de différence est comparée à un seuil de déclenchement. Si la moyenne de différence dépasse le seuil, une fibrillation auriculaire est déterminée, un déclenchement de mémoire a lieu, et les données de complexe QRS sont enregistrées à l'intérieur d'une période de temps sélectionnée pendant l'événement de fibrillation auriculaire et retirées de l'état de réécriture dans la mémoire. Un seuil de rétablissement, qui diffère du seuil de déclenchement, est utilisé et si la moyenne de différence descend en dessous du seuil de rétablissement, le procédé et l'appareil sont à nouveau capables d'enregistrer un nouvel événement de fibrillation auriculaire (AFIB).
