Patent CA-2328747-A1 (CA)
Title: Single-pass folded interleaver/deinterleavers
Inventor: CHANG KOK-WAI
IPC: H03M13/27
Filed: 2000-12-15
Abstract: Interleaver/deinterleaver apparatuses for combining/separating optical channels are described. An interleaver/deinterleaver apparatus is described as folded when an optical signal is directed through a single crystal multiple times. Single-pass refers to the optical signal following a (folded) path through the apparatus a single time.  When operating as an deinterleaver, the interleaver/deinterleaver separates an optical signal (e.g., WDM signal) into subsets of optical signals (e.g., channels). When operating as an interleaver, the interleaver/deinterleaver mixes subsets of optical signals (e.g., channels) into a multiplexed (e.g., WDM) optical signal. The interleaver/deinterleaver apparatus can be used to increase the bandwidth of an optical network. For example, the interleaver/deinterleaver can be used to interface components designed for a first channel spacing (e.g., 100 GHz) to components designed for a second channel spacing (e.g., 200 GHz).

Patent CA-2333529-A1 (CA)
Title: Bone anchor and deployment device therefor
Inventor: RICE JOHN
IPC: A61B17/04
Filed: 1999-05-27
Abstract: A rivet-like bone anchor has a floating washer at its head that can adapt to an angled bone surface and, thereby, better secure a tissue thereto. The anchor includes a rivet, an expandable sleeve, and a washer. The rivet includes a head and an elongate body having proximal and distal ends, the head being mounted on the proximal end of the elongate body. The expandable sleeve has an inner bore adapted to receive the rivet body. The washer "floats" at a proximal end of the sleeve. As the rivet is inserted into sleeve, the sleeve expands into an interference fit with the bone. The head of the rivet, moreover, forces the floating washer into contact with the tissue at an angle that conforms to that of the underlying bone surface. A deployment tool permits the anchor to be deployed without application of unnecessary counterforce. The tool includes an outer tube, the distal end of which can hold the anchor housing, e.g., via a screw fit. A rod, which is slidably disposed within the bore of the, tube, can be used to push the rivet into the expandable sleeve so that the sleeve expands into the bone, so that the floating washer is forced into position against the bone surface, and so that anchor is broken away from the housing. This can be effected, for example, by squeezing the distal ends of the outer tube and the rod together, e.g., in the manner that the end of a syringe is squeezed.
Patent CA-2334959-A1 (CA)
Title: Network management
Inventor: HANSEN NIELS QVISTGAARD
IPC: H04Q3/00
Filed: 1999-05-14
Abstract: The invention describes how telecommunication services can be handled in Access Networks (AN). A management concept is proposed that will enhance management by using a "loose coupling" between the defined telecommunication services and the transport network on which they are based. A "loose coupling"  means here that Managed Objects in the service layer and in the transport layer are not that tightly coupled due to a separation of service, protocol and transport resources. This means that the service definitions will not be directly or indirectly logically contained in a physical port. Two embodiments of the invention are shown to demonstrate its use and advantages.
