Title: Aneurysm patch apparatus and method for treating an aneurysm
Inventor: MAYNARD RONALD S
IPC: F03G7/06
Filed: 1997-10-29
Abstract: An aneurysm patch apparatus (10) for treating an aneurysm (30) formed in a vessel includes a vessel interface side (16) and an opposing non-interface side (18). A patch (14) is formed of a sufficiently flexible material to provide a patch stowed state when the patch is delivered through the vessel and a patch deployed state when the patch is at least partially positioned over the mouth of the aneurysm. The interface side of the patch is configured to form an adherence between the patch and an area of a vessel wall adjacent to the aneurysm mouth (28). The adherence (22) maintains a fixed position of the patch relative to the aneurysm mouth and can be achieved by use of vacuum, barbs, hooks, graspers, pinchers or the like. The patch delivery catheter (12) includes a first lumen (32) coupled to a low pressure source for collapsing the aneurysm, and a second lumen (36) for consequently applying adhesive to provide contact between patch and vessel wall.
Patent CA-2273025-A1 (CA)
Inventor: MCDONALD ANTHONY MALCOLM
IPC: H04R7/20
Filed: 1997-11-11
Abstract: An electroacoustic transducer comprises first and second panels (18A, 18B) each of which can be vibrated to generate sound, a frame (10) for mounting the panels, and first and second seals (20A, B) arranged between the frame and the edges of the panels for holding the panels in the frame, substantially isolating the frame acoustically from the edges of the panel, and substantially sealing the frame to the edges of the panel. One or more actuators (22), such as piezoelectric elements, are provided for receiving a driving signal and vibrating in response thereto, and the actuators are mechanically and acoustically coupled to the first panel at one or more locations remote from the edges of the first panel so that the first panel vibrates in response to vibration of the actuators. The second panel is mechanically and acoustically coupled to the first panel and/or to the actuators at one or more locations remote from the edges of the second panel so that the second panel also vibrates in response to vibration of the actuator means. The acoustic properties of the panels, the seals, the actuators and the couplings can be chosen to obtain a required frequency response from the transducer. Different embodiments are described in which the panels are driven in phase, in anti-phase, and in a more complex manner.

Title: A deployable diverging part for a thruster
Inventor: COLLIGNON LAURENT
IPC: F02K9/97
Filed: 1997-12-24
Abstract: A diverging ring is displaceable between a retracted position in which it surrounds a first portion of a diverging part and a deployed position in which it is connected to a downstream end of the first portion. A deployment mechanism causes the diverging ring to move from its retracted position to its deployed position under drive from actuation means. A temporary structure, or "insert", is placed inside the diverging ring so as to transform the diverging section thereof into a non-diverging section, at least over the major portion of the length of the diverging ring, the insert being eliminatable on or after the diverging ring coming into its deployed position.

Abstract: An emergency lighting system comprising a central monitoring and control unit, a plurality of single point lighting units and a communication system linking all of these units and being configured with a loop topology.      Addressing of single point units around the loop is achieved via a protocol whereby a first address is issued by the central unit to the first unit in the loop. This first unit then stores this address as its own and increments the address number before passing it on to the next unit in the loop and so on. When the last unit in the loop finally passes its own incremented address number back to the central unit this provides the central unit with the necessary information to determine the number of single point units in the system.

Title: Optical amplifier and process for amplifying an optical signal propagating in a fiber optic employing an overlay waveguide and stimulated emission
Inventor: SHIMAZU MICHAEL H
IPC: G02B6/124
Filed: 1998-12-08
Abstract: A side-polished fiber/overlay waveguide architecture (10) and process for non-invasively implementing an optical amplifier are provided for an optical communications system. A "channel" overlay waveguide (60) is employed to constrain for amplification optical energy evanescently coupled to the overlay waveguide from the side-polished optical fiber (30). One of two amplification methods can be employed. The first involves inducing stimulated emission with the overlay waveguide and the second uses a second order, non-linear frequency conversion to down-convert a high-power, short-wavelength pump signal into the waveguide to amplify the optical energy coupled thereto. Amplification of optical energy in the channel overlay waveguide (60) can be established within a single beat length of evanescent removal to evanescent return of the optical energy to the side-polished fiber optic.
