IPC: H04W4/24
Filed: 1996-10-04
Abstract: The load on the communications resources of a cellular telephone system is monitored (100) to detect instances of excess amounts of unused resource capacity (102). When such instances are detected, a message is transmitted to subscribers (106) via the cellular system offering reduced charging rates for calls initiated in response to the offering message. The subscriber mobile stations are programmed to alert (116) the subscriber to the broadcast of the offering message, after which the subscriber may initiate a reduced rate call (118). The mobile stations may further be programmed to automatically initiate the cellular call (124) in response to receipt of the offering message, and to thereafter engage in the communication. Monitoring of communications resources external to the cellular system is also made, and an offering message is broadcast by the system in response to detection of excess amounts of unused external resource capacity, in response to which subscribers may initiate calls requesting reduced rate access to the resource.

IPC: G06F11/14
Filed: 1998-06-29
Abstract: Configuration changes are dynamically applied to a cluster multiprocessing system by enqueuing a configuration change event. When the configuration change event is processed, the prior configuration is backed up and each software component applies a relevant portion of a configuration change transaction in an ordered, synchronized manner. Each software component applies its portion of the transaction either by reinitialization or a logged transition operation. If the configuration change transaction fails, the software components roll back the portions of the configuration change already applied in an ordered, synchronized manner to restore the prior configuration. Multiple events for different configuration changes may be enqueued.
Patent CA-2244030-A1 (CA)
Inventor: MACKNESS ROBERT F
IPC: B64C25/42
Filed: 1998-07-27
Abstract: An aircraft automatic braking system processes the flight crew selected stopping position of the aircraft on the runway via a control display unit (30) and the aircraft's actual position, provided by a global positioning system (34), to generate a stop-to-position deceleration control signal in a provided controllogic (36). If the flight crew selects the stop-to-position autobraking mode, the system determines whether or not a stop-to-position autobraking mode meets several predetermined criteria and, if the criteria are met, applies a control signal to the aircraft's braking system (62, 66) such that the aircraft is smoothly braked tending it to stop at the selected runway stopping position. The system eliminates the need for pilot lookup in a manual to determine a desired autobraking setting to choose based on altitude, temperature, approach speed and runway conditions and also operates to reduce pilot workload during limited visibility conditions.

Filed: 1997-01-31
Abstract: The invention relates to a process and apparatus for pretreating pulp raw material, to be subsequently prepared in a chemical pulping process, and for preparing cellulose pulp from a fibrous starting material. According to the process the starting material is delignified to yield a chemical cellulose pulp, and the obtained pulp is bleached when desirable. According to the invention the starting material is crushed in cooking liquor prior to delignification in order to open its fiber structure. The apparatus of the invention comprises a frame (21), to which two adjacent first rolls (12; 22, 23) have been fitted, which form a first pair of rolls with the rolls arranged to distance from each other in such a manner that a gap clearance is formed between their outer mantles. The rolls are caused to rotate by a means of power transmission, which causes the raw material to be crushed inside the gap between the rolls where a liquid pocket is formed, from which liquid is absorbed into the fiber material being treated. The invention provides even cooking of the raw material under mild conditions.
