Title: System and method for providing a graphical user interface to, for building, and/or for monitoring a telecommunication network
Inventor: CROWE WILLIAM LAWTON
IPC: H04Q3/00
Filed: 1999-12-15
Abstract: A system and method for providing a graphical user interface (GUI) for network development, management, and monitoring includes a GUI front end that provides a graphical representation of a telecommunication network comprised of communication devices represented by GUI network elements. A network proxy provides a communication layer between the GUI and a network server and allows the GUI to connect to multiple instances of a network server without having to hard code the connections to the network servers. The network proxy transmits commands and messages between the network server and the GUI. The network server determines how to handle traffic in the network model, such as how to provide call setup, call routing, and call tear down. The network server transmits call routing commands and messages to the network proxy which dispatches them to the GUI. An external systems interface provides the mechanism for which the network server communicates with communication devices in an external system.

Patent CA-2301591-A1 (CA)
Inventor: SHEPARD WILLIAM H
IPC: D04H3/10
Filed: 1998-09-03
Abstract: Lightweight, non-woven loop products for hook-and-loop fastening are disclosed, as are methods for making them and end products employing them. The products are non-woven webs of entangled fibers of substantial tenacity, the fibers forming both a sheet-form web body and hook-engageable, free-standing loops extending from the web body. The product is stretched and stabilized to produce spaced-apart loop clusters extending from a very thin web of taut fibers. In important cases a binder is added to stabilize the product in its stretched condition. An example of the loop product is produced by needlepunching a batt of staple fibers in multiple needle-punching operations, applying a foamed acrylic binder, and then stretching the needled batt and curing the binder with the batt stretched. Other forming techniques are disclosed and several novel articles and uses employing such loop products are described, such as for filters and fasteners.

Patent CA-2326664-A1 (CA)
Inventor: FRINK CRAIG R
IPC: H04N21/643
Filed: 1999-03-29
Abstract: An interface enables asynchronous data processing elements to be interconnected using an interconnection protocol that controls the flow of data between the processing elements. The flow control allows the processing elements to be data independent, i.e., the processing elements need not be designed for a fixed sample rate or resolution, sample format, or other data dependent factors. When used with digital motion video data, the processing elements may process motion video data at various temporal and spatial resolutions and color formats and precisions. Flow of data between processing elements may be controlled by handshake signals indicating whether the data output by the sender is valid and whether the receiver can receive data. The sender transmits data and asserts a valid signal along with the data in response to a request signal from the receiver. The request signal may be asserted by the receiver and responded to asynchronously by the sender with the transmission of the data by the sender. As a result, the sender and receiver are decoupled, thus enabling high speed data transmission and time division multiplexing of data across the interconnect. The sender may also transfer command data. A valid command is to indicate the presence of command data.
