Patent CA-2154678-A1 (CA)
Title: A digital communication system and a receiver for use in such a system
Inventor: BOT PAULUS GEORGE MARIA DE
IPC: H04J1/00
Filed: 1994-12-01
Abstract: Known in a digital communication system (1) are phase recovery methods for QPSK modulated signals. It is proposed to extend such methods to multi-resolution QAM signals, which can be represented by rotationally invariant signal constellations. To this end, with each received symbol (ri), a phase reference (øi) for a high priority-bit (HP-bits) constellation is determined, and with respect to this phase reference (øi), a sub-constellation (CLx) for low-priority bits (LP-bits) is construced, the sub-constellation (CLx) being rotationally invariant. The sub-configuration (CLx) is translated to an origin (O) of the signal constellation, and then the low priority-bits (LP-bits) are determined by determining a minimum squared Euclidean distance (Ed) of the rotated and translated received symbol (bi') with respect to the rotated and translated sub-constellation. For a 2R(2,2)-QAM signal constellation a simple detection method is thus provided. The method can be made adaptive, and can also be made recursive for more complicated signal constellations such as a 64-QAM signal constellation.

Title: Intraluminal Stent for Attaching a Graft
Inventor: FRANTZEN JOHN J
IPC: A61F2/06
Filed: 1995-11-15
Abstract: A graft-and-stent combination is disclosed for deploying by an intravascular delivery system at the site of an aneurysm, the combination being expandable from a first diameter to a second, larger diameter to hold open and press the graft against regions of the body lumen just proximal and distal to the aneurysm. The combination is characterized by one or more stents that are flexible due to independently expandable and interconnected cylindrical elements, which provide sufficient radial strength to the combination when the graft-and-stent are being attached to the vessel, but which nonetheless afford sufficient resiliency to allow a great degree of expansion at a rapid rate when the combination is being deployed. Attachment elements in the form of hooks are provided to securely affix the ends of the stent extending distally and proximally of the graft after expansion to the walls of the vessel just distally and proximally of the aneurysm.

Patent CA-2168341-A1 (CA)
Inventor: BOYER DAVID GRAY
IPC: H04R27/00
Filed: 1994-08-03
Abstract: Our audio processing system for use in teleconferencing systems includes a microphone (1-25), receiver (1-26), and substantially the same comb filter (1-42) and frequency scaler (1-60) at each station for reducing acoustic echo and increasing the margin of acoustic stability. The comb filters and frequency scalers cooperate with one another in that the frequency scalers each induces a shift in frequency which corresponds to the peak-to-trough spacing of the transfer function of the comb filters. Our audio processing system may also include auxiliary echo suppressors (410, 510) for reducing acoustic echo and increasing the margin of acoustic stability in systems having high and low transmission delays. Other devices may be employed for reducing noise and smoothing out the operation of individual components in the system. Since the comb filters employed at each station are not complementary, but are substantially the same, our audio processing system can mitigate the effects of acoustic instability and echo in point-to-point and multipoint audio processing systems. Furthermore, since each station utilizes substantially the same equipment, the need for equipment negotiation between stations and equipment changes prior to a conferencing session is obviated.
