Title: Dispositif permettant une surveillance non invasive de la pression arterielle d'un patient et procede correspondant
Inventor: SOMERVILLE ALVIS J
IPC: A61B5/021
Filed: 1997-12-12
Abstract: L'invention a trait à un dispositif permettant une surveillance de la pression artérielle d'un patient et ce, de façon non invasive. Dans ce dispositif, une membrane souple emprisonnant une enceinte remplie de liquide est comprimée contre les tissus sus-jacents à une artère, avec une force suffisante pour aplanir cette artère. Un premier système de commande optimise l'ampleur de l'aplanissement artériel, survenant à une pression transmurale d'une valeur sensiblement nulle, par modulation du volume du liquide contenu dans l'enceinte et grâce à une observation de l'effet résultant sur la pression régnant dans l'enceinte. Dans la mesure où il existe plusieurs effets de poussée selon l'ampleur de l'aplanissement artériel, un signal adapté de commande peut être généré, permettant d'obtenir la pression moyenne optimale de la membrane. De plus, un second système de commande à servocommande agit sur la position de la membrane en régulant le volume de liquide présent dans l'enceinte afin de compenser les écarts de pression dues au pouls artériel, ce qui a pour effet de minimiser des variations du diamètre de l'artère, la pression régnant dans l'enceinte remplie de liquide se conformant, par le fait, très étroitement aux oscillations de la forme d'onde réelle du pouls artériel.

Patent CA-2277120-A1 (CA)
Inventor: HOLLINGER DAVID P
IPC: G01V1/00
Filed: 1997-10-27
Abstract: A system for geophysical exploration uses a single source (30) which emits signals over multiple octaves. The source is driven by a composite sweep signal having two or more sweeps, one of which covers the lower octave (10) while the other sweeps cover the remainder of the bandwidth. The signals covering the lower portion are reduced in the case of a sweep which varies linearly with time in proportion to the square root of the ratio of the sweep rate of the signals covering the upper end to the sweep rate of the signals covering the lower end. The signals are transmitted simultaneously. Because of the composite sweep the same energy spectrum is transmitted as with a sine wave sweep which extends over the entire frequency band, while reducing the peak power and radiator displacement required at lower frequencies to maintain a flat spectrum. The size of the equipment can be reduced.

Patent CA-2291001-A1 (CA)
Inventor: LO WING
IPC: H04B1/707
Filed: 1999-02-10
Abstract: The present invention assigns a pair of user ID's to each user. The user ID's are used as addresses to access two orthogonal Walsh codes in a memory. Each Walsh code is 2n-bits in length and the memory size is 2n x 2n. The orthogonal codes are then used to cover the information symbols for transmission. This results in the transmitted signal being orthogonal to other users and also orthogonal within the transmitting user's own signal bursts.

Title: Reducing convergence time by a protocol independent multilcast (pim) router
Inventor: LI YUNZHOU
IPC: H04L12/56
Filed: 2000-02-17
Abstract: A technique for reducing reconvergence time by a reconverging device in a PIM-SM domain of a communication system involves sending by the reconverging device to a neighboring device a reconvergence message including a reconvergence indicator, such as a randomly selected Generation Identifier value. In response to the reconvergence message, the neighboring device sends to the reconverging device a PIM Bootstrap Message identifying the Rendezvous Point devices in the PIM-SM domain. The reconverging device creates the appropriate PIM-SM states for the Rendezvous Point devices. Additionally, the neighboring device sends to the reconverging device a PIM Join/Prune Message for each multicast group for which the neighboring device supports a downstream multicast group member. The reconverging device creates the appropriate routing entries for the multicast group memberships, and forwards each PIM Join/Prune Messages towards its corresponding Rendezvous Pointer device. Additionally, the reconverging device detects any directly connected multicast group members, and sends to the neighboring device a PIM Join/Prune Message for each multicast group for which the reconverging device supports a directly connected multicast group member.

Title: Apparatus for displaying images to viewers in motion
Inventor: SPODEK JOSHUA D
IPC: G09F19/14
Filed: 1999-07-28
Abstract: Apparatus for displaying still images to viewers in motion relative to those images, such as passengers on a subway train, includes a plurality of images mounted on a surface, and a slitboard mounted between that surface and the viewer. As the viewers pass by, the slitboard acts like a shutter, creating an animation effect. In addition, there is a stretching or widening effect that enlarges the images, allowing images to be "preshrunk," thereby allowing a large number of images in a small space, increasing the available frame rate of the animation. The stretching effect depends on the distance between the image surface and the slitboard.
