Filed: 1998-05-06
Abstract: A treatment tool such as a catheter, MIS or other surgical tool apparatus for placement within a heart chamber, organ aperture or other body opening and axial ranging therein, the apparatus particularly adapted for laser-assisted percutaneous transmyocardial revascularization (TMR). At the distal end of the tool is an annular ultrasound transducer with associated structure, positioned to transmit ultrasound signals substantially axially aligned with the axis of the treatment tool to the cardiovascular tissue, the transducer further receiving returning signals from the cardiovascular tissue to be treated. In a preferred embodiment, the transducer comprises a piezoelectric crystal material. The transducer assembly is attached to the distal tip of the tool such that a laser delivery means or other functional device can be extenced through the lumen of the tool and the annular ultrasound transducer. In a preferred embodiment, the invention is a modular ultrasound device capable of being detachably attached to a steerable catheter, MIS or other surgical tool apparatus. The system also comprises a signal interface extending from the ultrasound transducer and signal processing component operatively connected to the signal interface for real time determination of at least one boundary surface of cardiovascular tissue relative to one or more positions of the distal tip of the treatment tool. A method of delivering laser energy to tissue is disclosed, the method including the steps of positioning the firing tip of a laser delivery means adjacent the front surface of the tissue, delivering laser energy to the tissue, transmitting ultrasound energy to the tissue, receiving ultrasound signals reflected from at least the rear surface of the tissue, and determining the distance between the firing tip of the laser delivery means and the rear surface of the tissue. In a preferred embodiment, the method includes quantitative determination of the contractility or motion of the beating heart, such that changes in the depth of tissue can be used to control the channel depth or other treatment parameters. Retrolasing can also be achieved by mechanically piercing the tissue to a determined depth based on axial ranging measurements, and retracting the treatment tool while simultaneously delivering laser energy therefrom.

IPC: G01S7/02
Filed: 1996-12-13
Abstract: L'invention concerne un procédé de détermination du taux de précipitation par radar à double polarisation et un radar météorologique le mettant en oeuvre. Le procédé consiste, à partir des signaux reçus sur les deux voies de polarisation H et V du radar, à déterminer d'abord sur une seule polarisation une estimation des taux de précipitation <o>R</o>a (19, 30 à 32) le long du faisceau radar, dans chaque porte en distance i, puis une première valeur estimée (<o>I</o>1) de l'intégrale des taux de précipitation, enfin, à partir du coefficient de réflectivité atténué (ZHa(r)) une estimation (35 à 38, 47, 48) du coefficient de réflectivité différentielle non atténué (ZDRs(r)). Par ailleurs, on détermine (30, 40 à 42) la valeur mesurée du coefficient de réflectivité différentielle atténué (ZDRs(r)) et on en déduit (43, 44) l'intégrale (<o>I</o>2) des taux de précipitation qui est comparée (45, 46) à la première valeur estimée (<o>I</o>1) de manière à ajuster itérativement un paramètre (.alpha.) du procédé appliqué à la polarisation H seule. Lorsque .alpha. est ajusté, on dispose (38, 47) des valeurs corrigées du coefficient de réflectivité non atténué et du taux de précipitation. L'invention s'applique aux radars météorologiques.
Patent CA-2242560-A1 (CA)
Title: Water wheel with cylindrical blades
Inventor: BERGSTEIN FRANK D
IPC: F03B1/00
Filed: 1998-09-03
Abstract: An improved liquid rotor device is provided having a cylindrically-shaped hub, which is supported by a horizontal shaft, and having several curved blades which are attached to the outer portions of the rotating hub. The horizontal shaft preferably rotates with the hub so that it can mechanically drive a device such as an electrical generator. The multiple blades mounted to the exterior surface of the hub are curved such that the longitudinal axis of each blade is parallel to the axis of rotation (i.e., the horizontal shaft). Each blade is arcuate in shape and preferably comprises a portion of the cylindrical wall of a hollow cylinder. In one embodiment of the present invention, the rotating hub and blades sub-assembly is surrounded by a hollow cylindrical housing that is entirely submerged in a liquid, such as water. The surrounding hollow cylindrical housing has an inlet to receive the liquid into the area of the rotating blades and an outlet through which the liquid is discharged. The inlet preferably is in communication with the discharge of a constricting chamber that has a large opening area and a small discharge area, such as a portion of a venturi. By use of this chamber, the velocity of the liquid is increased as it approaches the inlet. In a second embodiment, the rotating hub and blades sub-assembly is made to be buoyant so that the centerline of the rotating hub will be approximately at the surface of the liquid, so that the liquid rotor will essentially float along the surface of, for example, a stream, river or canal. The curved blades are directly exposed to themoving liquid, as well as to the wind of the gaseous air above the surface of the liquid. If the direction of the liquid current is substantially the same as the wind direction, then the wind will tend to inhibit the rotation of the blades and hub sub-assembly. In order to provide a reduced cross-sectional area against which the wind can act, the curved blades are hinged at the surface of the cylindrical hub, so that the wind will have less surface area to act against.

Abstract: An insert-rack plug connection can be created between at least one sleeve portion (2) on a relatively fixed-position mother board (3) and at least one plug portion (4) on a relatively mobile daughter board (5). With that, the plug arrangement comprises a plug housing (6) mounted to displace axially on the daughter board and possessing a plug ferrule (7) mounted under preloaded axial spring tension. In addition, engagement means (8) for engagement of the plug housing into an engagement position in the sleeve portion are provided on the plug housing. In the insertion direction (x), the plug housing (6) is supported either directly of indirectly on a spring-action thrust element (9), the spring force of said thrust element maintaining the support until the engagement position has been reached, and subsequently automatically releasing said support on continued thrust movement. In this way, the daughter board (5) can be mechanically decoupled from the plug ferrule (7) or from the mother board (3) after reaching the engaged position in order to compensate mass tolerances. A U-shaped fork (9) preferably serves as a spring-action thrust element, the spring-action fork prongs of said fork being provided with thrust lugs (11) which coordinate with a mechanical thrust stop (14).

Abstract: A fiber which includes a thermoplastic polymer and particles of a ferroelectric material dispersed therein. The thermoplastic polymer may be, for example, a polyolefin, such as polypropylene or polyethylene, and the ferroelectric material may be barium titanate. The ferroelectric material may be present at a level of from about 0.01 to about 50 percent by weight (from about 0.001 to about 13 percent by volume), and will have a longest dimension in a range of from about 10 nanometers to about 10 micrometers. The fiber may be exposed to an electric field. A plurality of the fibers may be employed to form a knitted or woven fabric or a nonwoven web. Also provided is a method of preparing fibers containing particles of a ferroelectric material. The method includes destructuring the ferroelectric material in the presence of a liquid and a surfactant to give destructured particles; the liquid is a solvent for the surfactant and the surfactant is adapted to stabilize the destructured particles against agglomeration. A blend of the stabilized, destructured ferroelectric material particles and a thermoplastic polymer is then formed and extruded to form fibers. The extruded fibers may be collected on a moving foraminous support to form a nonwoven web and, if desired, may be exposed to an electric field. The fiber of the present invention, especially when in the form of a nonwoven web, is especially suited as a filtration medium. For example, the nonwoven web may be adapted to remove particulate matter from a gaseous stream.

Title: Direction determination in cellular mobile communications network
Inventor: SPEIGHT TIMOTHY JAMES
IPC: H04W64/00
Filed: 1999-03-09
Abstract: In order to improve carrier to interference ratios on the down link in mobile communications networks, it is proposed to transmit on the down link in a beam steered at the base station towards the mobile terminal.        In order to do that it is necessary to know in which direction the mobile terminal is located. There is disclosed a method of ascribing a direction to the location of a mobile terminal from an antenna array. A sequence of symbols from each antenna in the array, is stored. The sequence contains a known training sequence. The sequence is space processed iteratively so as to produce the effect of the array having a major lobe in its polar diagram at a plurality of different successive directions. A set of cross correlations metrics is derived by calculating a cross correlation metric for each direction between the combined signals and the known training sequence. The ratio is calculated of the cross correlation metric for each direction to the power of the combined signals for that direction to produce a set of direction metrics. A direction is ascribed to the mobile terminal using the direction metrics to determine which direction is most likely.

Title: System and method for processing wireless files based on filename extension
Inventor: SHAH NITIN JAYANT
IPC: G06F12/00
Filed: 1999-03-25
Abstract: A system for, and method of, processing a wireless file in a computer network and a communications infrastructure incorporating the system or the method.      In one embodiment, the system includes: (1) an examiner that receives at least a portion of the wireless file and identifies a filename thereof and (2) a file processor that modifies a content of the wireless file based on the filename.      The present invention therefore introduces the broad concept of employing a filename (or a portion thereof) of a wireless file to determine whether or what type of processing is to be performed with respect to the wireless file. "Wireless file" is defined, for purposes of the present invention, as any file that contains communications data. These data may form a datastream. The data may be audio, video or image data (user data) or may be wireless information (control data employed in communicating the user data).      In one embodiment of the present invention, the examiner identifies an extension of the filename. In an embodiment to be illustrated and described, the extension is selected from the group consisting of: .wdf ("wireless data format") and .wif ("wireless information format). Of course, other parts of the filename, or the whole filename, may be employed to determine the type or extent of wireless file modification required.     In one embodiment of the present invention, the examiner is associated with tree Internet. However, those skilled in the art will readily understand that the examiner or the file processor may be associated with any other computer network, one or more wireless base stations, one or more switches or any other part of a conventional or later-developed communications infrastructure.      In one embodiment of the present invention, the file processor modifies the content by performing an action selected from the group consisting of: (1) correcting an error in the content and (2) filtering the content. Those skilled in the art are familiar with other actions that may be taken with respect to data to improve the fidelity or quality thereof or otherwise to modify the data. All such types of modification are within the broad scope of the present invention.      In one embodiment of the present invention, the content is compressed. The compression technique may be any conventional or later-developed technique. Of course, the content need not be compressed.

Title: Protein stabilized pharmacologically active agents, methods for the preparation thereof and methods for the use thereof
Inventor: LOUIE LESLIE
IPC: A61K47/42
Filed: 1997-09-24
Abstract: In accordance with the present invention, there are provided compositions and methods useful for the in vivo delivery of substantially water-insoluble pharmacologically active agents (such as the anticancer drug paclitaxel) in which the pharmacologically active agent is delivered in the form of suspended particles coated with protein (which acts as a stabilizing agent). In particular, protein and pharmacologically active agent in a biocompatible dispersing medium are subjected to high shear, in the absence of any conventional surfactants, and also in the absence of any polymeric core material for the particles. The procedure yields particles with a diameter of less than about 1 micron. The use of specific composition and preparation conditions (e.g., addition of a polar solvent to the organic phase), and careful selection of the proper organic phase and phase fraction, enables the reproducible production of unusually small nanoparticles of less than 200 nm diameter, which can be sterile-filtered. The particulate system produced according to the invention can be converted into a redispersible dry power comprising nanoparticles of water-insoluble drug coated with a protein, and free protein to which molecules of the pharmacological agent are bound. This results in a unique delivery system, in which part of the pharmacologically active agent is readily bioavailable (in the form of molecules bound to the protein), and part of the agent is present within particles without any polymeric matrix therein.
