Patent CA-2270978-A1 (CA)
Title: Method and apparatus for determining pressures associated with the left atrium
Inventor: HICKEY DONALD D
IPC: A61B5/00
Filed: 1996-11-04
Abstract: This invention is a non-invasive apparatus and method, which need not require a physician for use thereof, for obtaining quantitative determinations of left atrial pressure values. A balloon (24) is inserted by means of a catheter (22) into the esophagus and positioned adjacent the left atrium. The balloon (24) is gradually inflated. In accordance with the oscillometric principle, the mean balloon pressure is measured when the intensity of a sound wave, after its transmission through the balloon (24), is at a peak. This mean balloon pressure, after adjustment for the effect, if any, of heart weight, is indicative of approximate mean left atrial pressure. Mean left atrial pressure may be determined by adjusting for the effects of heart weight and intrapleural pressure on mean pressure at peak sound intensity by subtracting therefrom the balloon pressure at which balloon volume begins to increase greatly relative to the increase in balloon pressure.

Title: Multiple conductor security tag
Inventor: MCEWING DAVID G
IPC: G08B21/22
Filed: 1999-05-14
Abstract: A security tag having a strap for securing the tag to an object to be protected and an electronic module connected to the strap for detecting an attempt to defeat the tag by short circuiting and severing the strap. The strap is formed of plural discrete conductors connected to the electronic module, which conductors are insulated from each other at least along a substantial length of the strap. Short circuiting of opposite ends of a single pair of the conductors followed by severance of plural ones of the insulated conductors, or short circuit in between separate conductors can be detected by the electronic module as an alarm condition. Severance or misconnection of only one or a small number of the insulated conductors can be detected by the electronic module as not being an alarm condition.

Patent CA-2275770-A1 (CA)
Title: Rejet d'interferences d'emetteurs
Inventor: GLADH OLLE
IPC: H01Q1/52
Filed: 1997-12-16
Abstract: L'invention concerne de manière générale l'utilisation d'un système de réseaux d'antennes, employés par exemple, dans des systèmes émetteurs-récepteurs mobiles. Des signaux parasites proviennent des réseaux d'antennes adjacents. Il en résulte des produits d'intermodulation ("IM") qui troublent la transmission des signaux désirés. Ces produits IM étant transmis le long du trajet compris entre l'amplificateur et l'élément antenne, il est possible d'ajuster la longueur de ce trajet d'un élément à l'autre, ce qui décale le front d'ondes des produits IM pour les rendre moins cohérents. Afin de maintenir une longueur totale de transmission constante pour le signal souhaité, la longueur entre le répartiteur et l'amplificateur est ajustée de manière à maintenir constante la longueur totale de transmission entre le répartiteur et l'élément antenne. Le front d'ondes du signal souhaité demeure ainsi cohérent, ce qui n'est pas le cas de celui des produits IM. On obtient ainsi une réduction des interférences provenant des produits IM.
Patent CA-2277494-A1 (CA)
Title: Laminated shingle
Inventor: MALARKEY GREGORY
IPC: E04D1/26
Filed: 1999-07-12
Abstract: Laminated shingles are manufactured from roll stock roofing material that is wider than that used to make similar laminated shingles. The roll stock includes longitudinal edge strips having a reduced thickness. The roll stock is cut into strips of tabbed top sheets and backing sheets. The strips of material used for the backing sheets are at once wider than commonly used in the industry, and include the longitudinal edge strips of reduced-thickness material. Because the backing sheet is wider two rain seal strips are laid down on the backing sheet prior to being laminated to the tabbed top sheet. The backing sheets are laminated to the tabbed top sheets with the longitudinal edges aligned. The wider backing sheet provides a substantially wider nail zone. In addition, since it allows for a second rain seal strip, provides somewhat more protection against leakage. The portion of the backing sheet that comprises the added width is relatively thinner than the remaining portions of the sheet. Paired shingles may therefore be oriented adjacent one another in opposite directions and stacked and bundled. The total thickness of the stack will be the same throughout the stack, so the stack of shingles is flat.

Patent CA-2293974-A1 (CA)
Inventor: HOST GERALD
IPC: G09F25/00
Filed: 2000-01-17
Abstract: The present invention is a system and method for targeting and sending advertising and content messages to wireless users via standardized message channels of the wireless network assuring strict individual privacy of wireless users. The network contains a plurality of clusters comprising two physical nodes communicating with each other via a public network. The first, the mediation server, receives raw positioning data from the wireless network and sends generic mobility data with encrypted personal identities to the profiling server. This latter tracks and profiles real-time and non-real time mobility data compiling data bases of wireless user profiles to permit targeting of individual advertisements. The profiling server targets multimedia-advertising messages to users with matching profiles and forwards those messages to the mediation server for encryption and further message compilation and transport. Wireless user privacy is achieved by separation of data collection and message transmission functions from the profiling and targeting functions.
