Patent CA-2278617-A1 (CA)
Title: A scalable low-latency switch for usage in an interconnect structure
Inventor: HESSE JOHN E
IPC: H04L45/02
Filed: 1998-01-22
Abstract: A scalable low-latency switch extends the functionality of a multiple level minimum logic interconnect structure for usage in computers of all types, networks and communication systems. The multiple level minimum logic interconnect structure employs a data flow technique based on timing and positioning of messages moving through the structure. The scalable low-latency switch is distributed throughout multiple nodes in the structure so that a supervisory controller providing a global control function and complex logic structures are avoided while the interconnect structure operates as a "deflection" or "hot potato" system in which processing and storage overhead at each node are reduced. The interconnect structure using the scalable lowlatency switch employs a method of achieving wormhole routing through an integrated circuit chip by a novel procedure for inserting messages into the chip. Rather than simultaneously inserting a message into each unblocked node on the outer cylinder at every angle, messages are inserted simultaneously into two columns A and B only if an entire message fits between A and B. Messages are inserted into column 0 at time 0. Messages are inserted into column 1 at time t0+tC, where time tc is the time for a first bit of a message to move from column 0 to column 1 on the top level. Messages are inserted into column 2 at time t0+2tC, and so forth. The strategy prevents the first bit of one message from colliding with an interior bit of another message already in the switch. Contention between entire messages is addressed by resolving the contention between the first bit only so that messages wormhole through many cells.
Patent CA-2281044-A1 (CA)
Inventor: CHENG YIHAO
IPC: G02B6/34
Filed: 1999-08-27
Abstract: A multiplexor/demultiplexor employs a bulk grating, an array of input/output waveguides, and a lens between the grating and the array of waveguides. A  concentrator chip is disposed between the array of waveguides and the lens for providing closely spaced waveguides for transmitting/receiving light to/from the lens in a multiplexing/demultiplexing mode of operation respectively. At another end of the concentrator chip waveguides are less closely spaced to couple with the array of input/output waveguides. Since the core separation of the of the cores of the receiving waveguides (in a demultiplexing mode) is inversely proportional to the bandwidth of the demultiplexed channels, providing closely spaced cores provides wide bandwidth separated channels.

Patent CA-2289659-A1 (CA)
Inventor: LA RUE DAVID L
IPC: H04M3/42
Filed: 1998-05-19
Abstract: A system and method for providing call center services, such as customer surveys and order rentry, is data-driven and can be used to perform services for many different customers, without developing a separate application program for each customer. A product, running as an application on a PC  workstation, provides basic call flows that are easily customized for specific customers by integrating customer profiles with an underlying application. The underlying application retrieves pre-defined customer profiles for various services at start up. When an agent workstation receives a call, the application references the particular customer profile by a key, such as the called number. The application then performs one of several basic call flow processes, such as a question and answer survey, taking orders for a customer's product, etc., under the customer profile. The application reads and interprets the customer profile, and inserts information specific to that customer into specific places during the call process.

Title: Expandable annuloplasty ring
Inventor: CARPENTIER ALAIN
IPC: A61F2/24
Filed: 1998-07-22
Abstract: An expandable annuloplasty ring which may either expand spontaneously, in situ, as the patient grows or be expanded by surgical intervention by balloon dilatation.      The distensible annuloplasty ring of the invention may be usable in pediatric patients whose growth, subsequent to surgical implantation of the ring, will necessitate subsequent enlargement of the ring to accommodate growth of the annulus. The ring may include relatively expandable segments to enable the enlargement thereof.      The ring segments may include engaging teeth which cooperate with notches or slots formed in the tubes to provide some resistance to ring distention, while preventing collapse of the ring in the opposite direction.      The teeth may be of different sizes or shapes to regulate the amount of force needed to expand the ring at different stages of the patient's growth. Alternatively, the adjustable ring includes a solid core of non-elastic material which plastically retains its shape upon natural expansion of the annulus, or after surgical expansion. In one embodiment, segments are coupled together with a discontinuity around the ring periphery. Pivot regions are provided between adjacent segments that, along with the discontinuity, enable the ring to expand upon annulus growth. The discontinuity may be positioned along the anterior side of the ring or around the posterior side. A further version makes use of telescoped segments with no discontinuity. The segments are coupled together with tubular sheaths, and expand without decoupling. A fabric covering may be omitted.
