Patent CA-2374200-C (CA)
Title: Flexible stent
Inventor: BURGERMEISTER ROBERT
IPC: A61F2/06
Filed: 2002-03-01
Granted: 2007-04-10
Abstract: A preferred embodiment of a stent provides a folded strut section that provides both structural rigidity and reduction in foreshortening of the stent mechanism. A flexible section provides flexibility for delivery of the stent mechanism. In a second embodiment, flexible section columns are angled with respect to each other, and to the longitudinal axis of the stent. These relatively flexible sections are oppositely phased in order to negate any torsion along their length. In yet another embodiment, the flexible connector can take on an undulating shape (like an "N"), but such that the longitudinal axis of the connector is not parallel with the longitudinal axis of the stent. Finally, a new method is disclosed for making stents. The method consists of performing a standard photochemical machining process of cutting, cleaning and coating the tube with a photoresist. However, unlike former methods, the photoresist image is developed on the surface of the cylindrical metallic tube, which results in a controlled variable etching rate at selected sites on the cylindrical metallic tube during the etching process. Further embodiments provide living hinge connectors and connections along the length of the radial strut member.

Abstract: A method and apparatus for detecting mastitis in a short time with high accuracy by optically counting somatic cells in raw milk or in an udder. The apparatus comprises a light source (1) emitting measurement light, a spectroscope (9) for extracting only a desired wavelength from the light from the light source by dispersing the light, a light chopper (14) disposed between a lens (11) and a reflecting mirror (12), an integrating sphere (13) formed of a light-diffusing member, and a sample holder (40) holding a sample such as raw milk. Near infrared radiation is applied to raw milk or an udder, the intensity of transmitted, reflected, or transmitted/reflected light of predetermined wavelength is measured, and multivariable analysis by the SIMCA method is conducted, thus detecting mastitis from the spectrum of the light from raw milk or an udder.

Title: An improved power saving function for wireless lans: methods, system and program products
Inventor: BEACH ROBERT
IPC: H04W24/00
Filed: 2002-04-09
Granted: 2010-12-07
Abstract: A wireless data communication system has a first station or mobile unit is linked to a second station configured as an access unit to support packet communication, voice or data, where the voice packets are transmitted in the Continuously Aware Mode (CAM) mode while other packets are buffered by the access point and held until asked for by the first station when in a Power Saving-Poll (PSP) mode. A monitoring apparatus at the access point monitors all transmitted packets and sorts the packets to the mobile unit according to CAM  or PSP mode.  Voice packets are sent out immediately to the mobile unit. Other packets are stored at the access point. The packet arrival rate may vary during transmission and due to random packet delays introduced by propagation characteristic and processing apparatus. The packet arrival rate and delays are taken into account by the first station in an algorithm to determine and extend the normal safe period in which the station receiver may be powered off.

Abstract: L'invention concerne des procédés et des dispositifs permettant de mieux mesurer la dilatation thermique et/ou la réactivité chimique d'agrégats utilisés dans le béton et dans d'autres matières semblables. L'agrégat est placé dans la chambre d'une cuve métallique à grande ouverture et dans un bain d'eau. Posé sur la cuve, un couvercle hermétiquement étanche porte un transducteur différentiel à variation linéaire (LVDT). Il comporte également un thermocouple destiné à capter la température, ce qui permet à un capteur, posé sur ledit thermocouple, d'entrer en contact avec le bain d'eau lorsque ledit couvercle est fixé à la cuve. Le LVDT est fonctionnellement raccordé à un dispositif de stockage ou d'enregistrement. Dans un mode de réalisation préféré, le couvercle comporte un élément tour doté d'un flotteur librement mobile et solidaire d'une tige de guidage. Le mouvement du flotteur indique un changement volumétrique aux niveaux de l'agrégat et de l'eau. On utilise le dilatomètre pour établir des informations se rapportant à la valeur de la dilatation ou de la contraction de l'agrégat en réponse à des changements thermiques. En outre, ces dispositifs et procédés permettent de déterminer le degré de réactivité de l'agrégat. On peut également déterminer uniquement le changement volumétrique de l'agrégat au moyen d'équations qui isolent et éliminent le quotient de dilatation de l'eau.
