Patent CA-2026872-A1 (CA)
IPC: H04L69/40
Filed: 1990-10-03
Abstract: The data flow is composed of data cells which are each transmitted via one of said transmission channels and which each comprise a control word group containing one or more control words and also an information word group containing one or more information words. A number of variables is maintained which, on arrival of a data cell at a certain location, are each altered in accordance with a alteration algorithm and are then processed in accordance with an evaluation algorithm to produce an evaluation signal. One or more of such evaluation signals are processed in accordance with a combination algorithm to produce a control signal and in which method a data cell is, or is not, transmitted, depending on the value of the control signal. . One of a plurality of quality classes is assigned to each of the data cells and for each quality class, a first variable is maintained which relates to the number of data cells having the respective quality class, which first variable is altered in accordance with a first alteration algorithm when a data cell arrives at a first location (I) and is processed in accordance with a first evaluation algorithm to produce a first evaluation signal. . Each of the virtual transmission channels is divided into one or more groups which each comprise one or more of said transmission channels and which each comprise those virtual transmission channels which make use of a particular potential congestion point in the transmission system and for each group of virtual transmission channels, a second variable is maintained which relates to the number of data cells to be transmitted via the respective group of transmission channels, which second variable is altered in accordance with a second alteration algorithm when a data cell arrives at a second location (I,II,III) and is then processed in accordance with a second evaluation algorithm to produce a second evaluation signal. . Depending on the value of the second evaluation signal and depending on the value of the respective quality class, the first alteration algorithm or the first evaluation algorithm or both are controlled in a manner such that, if the number of data cells of the respective group of channels is relatively large, the number of data cells transmitted is reduced and this will be the more so, the lower the quality class is.
Patent CA-2027230-A1 (CA)
IPC: H04L12/413
Filed: 1990-10-10
Abstract: The present invention provides a method and apparatus for establishing point-to-point full duplex communication between two stations served by a local area network (LAN) or connected by a communication link.  One station initially transmits a request message through the link.  The request message indicates that a first station is available for full duplex communication and also serves as a test to determine whether any non-full duplex devices are present along the point-to-point link between the first station and a second station.  A second station receives the request message and responds by transmitting a reply message which indicates its availability for full duplex communication.  Subsequently, full duplex communication may commence.  The two stations periodically exchange additional messages to continuously verify that full duplex communication is operating properly.

Patent CA-2067814-A1 (CA)
Title: Method for radiation detection and measurement
Inventor: MILLER STEVEN D
IPC: G01T1/105
Filed: 1990-10-31
Abstract: M-center luminescence is used to measure radiation. An LiF crystal (20) is excited with a 442 nm He-Cd laser because absorption measurements in LiF indicate the peak of the M-center absorption occurs at 443 nm. Laser stimulation produces an excited state of the M-center, which undergoes a very strong Stokes' shift.  The peak of the M-center emission spectrum occurs, at 665 nm with a half-width of 0.36 ev. Since the excitation wavelength differs significantly from the emission wavelength, measurement of the deep red emission can be done simultaneously with the excitation. The population of M-centers grows with increasing radiation damage, and therefore M-center luminescence provides a basis for radiation dosimetry.
