Granted: 2006-08-08
Abstract: The present invention is directed to a method of and a device for monitoring , from a central location, the current operating conditions (such as values of process parameters) in a process control network having distributed control functions. In one embodiment, the method and device of the present invention use scheduled periodic communications to send signals containing, for example, measured values of process parameters developed by field devices to a centralized viewing devic e. The viewing device receives the signals and stores at least one value of the process parameters, and maybe more values if necessary to monitor and control the process. To retrieve the stored process parameters for viewing, the viewing device processes messages from humain interface devices requesting the stored values of one or more of the stored parameters and then transmits response messages containing the stored values. The humain interface device may be the same device as the viewing device, or may be a separate device that communicates with the viewing device using either the same or a different communication protocol as that used by the field devices to communicate with the viewing device. Additionally, the request and response messages may be sent between the devices using unscheduled queued communications.
Patent CA-2337285-C (CA)
Inventor: ALLAYE-CHAN MARK
IPC: H04Q11/04
Filed: 2001-02-15
Granted: 2004-12-14
Abstract: A traffic recovery mechanism for communication networks uses a layer-1 adaptive rate protection scheme that compliments layer-3 restoration mechanisms. The protection scheme allocates less bandwidth to the traffic during a protection switch than during the normal operating conditions. This scheme allows the network to roll off more gracefully from the perspective of the applications routed through it. Rate adaptation is effected by a new interface between the data equipment and the transport network, which switches information transfer rate between two or more predetermined levels.

Title: Scattering parameter calibration system and method
Inventor: PEACH ROBERT
IPC: G01R27/28
Filed: 2000-02-01
Granted: 2005-11-01
Abstract: A system and method of calibrating an S parameter measurement instrument (such as a vector network analyzer) in which the number of calibrations required to fully characterize the error model of an n-port system is n/2 calibrations for an even number of ports and (n+1)/2 calibrations for an odd number of ports. Each test port in the system is involved in at least one full calibration, thus n/2 test paths are fully calibrated. For each measured test path, the error terms of the applicable error model are calculated. These error teens are then decoupled from the associated test path into error parameters that are localized to the individual test ports of the test path. Having localized the error parameters, the error model for each test port can then be treated independently from the other test ports. The error terms for the test paths that are not calibrated are then constructed using the localized error parameters for the individual test ports.
