Patent CA-2227366-A1 (CA)
Inventor: STAGG ARTHUR JAMES
IPC: H04L12/56
Filed: 1998-01-16
Abstract: Management of datastream construction prior to transmission of the datastream across a channel of a communications system by providing for data blocking while reducing movement or copying of the data improves the performance in a communications system. Multiple header segments received from a higher layer in the communications stack are copied into the datastream header area of a datastream such that the header segments are sequentially stored in the datastream header area. A datastream buffer list having entries referencing the datastream header area is generated. Buffer list entries referencing data segments received from higher layers in the communications stack are also stored in the datastream buffer list. The data segments are not physically moved or copied into the datastream during processing by the communications stack. Rather, a "virtual" datastream is generated by the communications stack for transmission without physically moving or copying the data segment. The datastream is transmitted across the channel by the system input/output interface by first writing the datastream header area referenced by the datastream buffer list directly into the channel, and the data segments directly from their original storage location into the channel of the communications system using the datastream buffer list entries.

Patent CA-2241238-A1 (CA)
Inventor: PCSOLAR DAVID J
IPC: B60T17/22
Filed: 1998-06-22
Abstract: An improved method is used to control the pressure in the brake pipe of a train. The train is equipped with an automatic brake handle, an equalizing reservoir, a brake pipe control device and a computer for controlling the control device according to position of the handle. The method involves the steps of: moving the handle to a point along its range of motion; and storing in the computer as a setpoint the value desired for the pressure in the brake pipe. At whichever point the handle occupies along its range of motion, there is a particular pressure setpoint corresponding thereto.      The method next includes the steps of: directing the computer to command the control device to modify the actual pressure in the equalizing reservoir to the setpoint thereby also causing the actual brake pipe pressure to approach the setpoint. As the actual brake pipe pressure approaches the setpoint, the computer is directed to command the control device to adjust the actual equalizing reservoir pressure to a value slightly above (if desiring to increase brake pipe pressure) or below (if desiring to decrease brake pipe pressure) the setpoint until the actual brake pipe pressure reaches the setpoint.      While monitoring the actual brake pipe pressure, the computer then commands the control device to adjust the actual equalizing reservoir pressure to maintain the actual brake pipe pressure at the setpoint corresponding to position of the brake handle.
