Title: Catheter system with balloon containing a radioactive fluid
Inventor: APPLE MARC G
IPC: A61F2/958
Filed: 1997-04-29
Abstract: A catheter apparatus filled with a radiation carrier material such as an inert radioactive gas for the treatment of restenosis after angioplasty, and malignancies. The inflated catheter includes a plurality of discrete chambers for transporting the radioactive carrier material, and a plurality of discrete chambers enabling substantial blood flow through the artery during treatment with the prescribed radiation. The inflated catheter may also comprise one unit balloon. A specific metal coating enhances the radiation dose delivered to the target. The wall of the lumen attenuates transmission dose to the blood circulating through the hollow inner lumen of the catheter device. The system also creates increased by-product radiation, from the impact of beta particles and gamma protons traveling toward the lumen wall. In addition, two opposing balloons whereby gas-tight redirection of radioactive gas flow from one balloon to the other, enabling one balloon to be inflated and delivered treatment dose, while the opposing balloon is deflated.

Patent CA-2260687-A1 (CA)
Title: Bi-directional configurable optical add/drop circuit
Inventor: VISVANATHA KUMAR
IPC: H04B10/43
Filed: 1999-02-04
Abstract: The present invention relates to a bi-directional configurable optical add/drop circuit. A symmetrical arrangement of serially coupled wavelength specific filters which include central add and drop ports isolated in both directions by filters provides a bi-directional circuit. Add and drop ports are coupled by a reflecting means, such as movable mirrors, or a movable double sided mirror. Alternatively, redirecting means comprise an opto-electronic, or other means, for providing a selectively reflective or transmissive interface. The reflecting means has a first position to direct a channel passed through a first filter to the drop port. If a new channel is added, the reflecting means couples the new channel through a second filter to the output port. In a second position, the reflecting means is moved from the beam path, permitting the channel to pass through the circuit without being dropped. In this way selected channels can be dropped, while others are allowed to pass. The reflecting means may be rotated or a second redirecting means substituted to reconfigure the circuit for signals propagating in the reverse direction to provide bi-directional coupling to the drop receiver and add transmitter. By applying absorption material to the surface of the reflecting means, an attenuation function can be added to the add/drop circuit. The configuration can be modified in operation. Numerous add/drop circuits can be arranged in parallel to address a large number of channels. A number of broad band filters first separate and direct selected channels to each add/drop circuit.

Title: Attachment bolt locking assembly
Inventor: LARIMORE STEPHEN W
IPC: F16B39/10
Filed: 1998-11-17
Abstract: A locking assembly (20) that mechanically locks an attach-ment bolt (11), such as one used to secure a missile launcher (10) to an aircraft, for example, thus preventing the bolt from vibrating loose as a result of vibration experienced during flight. The lock-ing assembly has a spring loaded locking nut (23) that mechanically engages a hex head (24a) of an extension shaft (24) that is coupled to the attachment bolt. Transverse pins (22) permit axial movement of the locking nut but prevent rotation thereof. A socket is used to push the locking nut away from the hex head of the extension shaft, so that the attachment bolt can be loosened or tightened. When the socket is removed, a spring (25) pushes the locking nut over the hex head of the extension shaft, locking the attachment bolt and preventing it from turning.

Title: Knowledge provider with logical hyperlinks
Inventor: SCHROEDER NORBERT
IPC: G06Q10/10
Filed: 1998-10-05
Abstract: A system and method is described for the efficient management and storage of documents in a multi-user environment by implementing a three-tiered content model for storage and a context resolution mechanism for retrieval. Source objects may logically reference target objects where the target objects dynamically exist in different versions. In particular, the content model contains three classes in a collection wherein each subsequent class inherits the properties of the previous class.  The classes comprise logical objects, physical objects, and files. All physical objects in the same collection are necessarily versions of each other, and are simply instances of the logical object. A versioning system allows the creation of variants of objects in the same collection. Furthermore, a context resolution mechanism is used to retrieve the most accurate version of an object pursuant to certain user-supplied criteria in response to a call from a client front-end application.

IPC: H04B1/707
Filed: 2000-05-25
Abstract: A data channel for transmitting data from a base station to subscriber stations is provided. Each subscriber station has a different service-class which reflects the reception-quality of the data transmitted from the base station. The data channel is organized into a plurality of frames. Each frame contains service-class information that is packaged in the frame in such a manner that all subscriber stations can recover the service-class information. The frame also includes payload data destined for at least one of the subscriber stations. The payload data is packaged in the frame in such a manner that the subscriber station having payload data destined therefore can recover its payload data, regardless of its service class. Subscriber stations that have no payload data destined therefore, and/or which are in a poorer service-class than the destined subscriber-stations, can use the service-class information to determine that the remainder of the frame can be ignored. An apparatus, system and method relating to the data channel are also provided.
