Patent CA-2216181-A1 (CA)
Inventor: DUCOUSSO PATRICK
IPC: B63B21/14
Filed: 1997-09-19
Abstract: The invention relates to a vessel comprising at least one anchor line (15).  Disconnect means are attached to the anchor line for releasing the vessel from the sea bed.  A first part of the disconnect means (16) is directly attached to the vessel and a second part is attached to the anchor line (17). Upon detaching the anchor lines from the vessel, no cables will protrude from underneath the vessel after disconnecting.  Thereby the risk of interference of the anchor lines with the vessel itself, with other vessels or with objects on the seabed in shallow waters is avoided.  Furthermore can the disconnect means according to the invention be directly controlled from the vessel.  Also can inspection and maintenance be easily performed.   Preferably the vessel comprises two or more anchor lines,  each anchor line having a disconnect means which can be independently operated.  Thereby a staged release of the anchor lines is possible which may be adapted to weather conditions or approaching objects such as icebergs.

Patent CA-2224349-A1 (CA)
Inventor: GROGER HOWARD P
IPC: G01N21/55
Filed: 1997-12-10
Abstract: Fluorescence measuring methods and apparatus use planar optical waveguides to excite fluorescence in the evanescent field of the waveguides and photodetectors to sense the fluorescence produced. Chemically sensitive fluorophores are bound to the evanescent regions of the planar optical waveguides. Substrates support the waveguides. Photodetectors, positioned in the substrates with fields of view normal to the waveguides, detect the fluorescence. Wavelength-selective material coating surfaces of the photodetectors allow fluorescence to be detected while restricting entry of light at the excitation wavelengths. The photodetectors have high aspect ratios for detection of fluorescence generated by the optical waveguides. Preferably, the photodetectorsare closely coupled to the fluorescence generated in the evanescent field of thewaveguide. In alternative embodiments, lightguides near the waveguides direct fluorescence from the plane of the waveguides for transmission by integrated optical fibers to remote sensors. For chemical detection and analysis, energy isintroduced to an edge of the waveguide. The edges are coated to reflect the energizing energy throughout the waveguide. The energy excites the chemically sensitive fluorophore film positioned on the waveguide. Inexpensive photodetectors without expensive photo-multipliers are mounted in substrates beneath the waveguides or at ends of lightguides extending from the substrates for detecting fluorescence.

Patent CA-2230549-A1 (CA)
Title: Automatic routing technique
Inventor: ASH GERALD R
IPC: H04M3/00
Filed: 1998-02-26
Abstract: The routing of calls from one network (100) to another network (170) may be accomplished by tracking the call completion history over each trunk group (174 1-174 2) connecting the networks. From a knowledge of the call completion history for each route, a Completion Rate Factor (CRF), representing the ratio of completed calls to all calls attempted is computed. The route having the CRF representing the highest number of completions is then selected. Typically, the process is dynamic, so that if the selected route no longer has the highest number of completions, then the route previously found to have the highest number of call completions is selected. The concept of completion rate factor routing can be extended to multiple carriers to yield a carrier completion rate feature routing technique. Routing may also be completed in accordance with network congestion to route advance a call.
