Title: Cooperative autonomous and scheduled resource allocation for a distributed communication system
Inventor: LOTT CHRISTOPHER G
IPC: H04L12/56
Filed: 2004-08-03
Abstract: An access terminal (206) configured for wireless communication with an access network (204) within a sector (1032). The access terminal (206) includes a transmitter (2608) for transmitting a reverse traffic channel to the access network (204), an antenna (2614) for receiving signals from the access network (204), a processor (2602) and memory (2604) in electronic communication with the processor (2602). Instructions stored in the memory (2604) implement a method of determining whether a current power allocation grant (1374) for a flow (1216) on the access terminal (206) has been received from the access network (204). If the current power allocation grant (1374) is still active, a current power allocation (1338a) for the flow is set equal to the current power allocation grant (1374). If the current power allocation grant (1374) has not been received, the current power allocation (1338a) for the flow is determined.

Title: Diesel engine control system with optimized fuel delivery
Inventor: FLYNN PAUL
IPC: F02D41/14
Filed: 2005-01-19
Abstract: A system (400) and method of determining fuel demands of a locomotive engine (10) based upon engine speed and power produced by the engine at a given time, so to optimize the engine's power output for a load while reducing engine emissions. The engine control architecture comprises three interrelated control loops (100-300). A primary feedback control loop (100) employs integral type control with gain scheduling to regulate engine speed to commanded slew rated based upon the locomotive's operator commands. A second control loop (200) provides an active, feed forward or predictive control consisting of a plurality of correction functions each utilizing a Taylor series having coefficients for each term in the series, the coefficients being modified to adapt the system to the engine with which it is used. A control third loop (300) optimizes reference speed slew rates and engine load rates by providing feedback of nominal engine fuel requirements or fuel demand, corrections to fuel demand based upon outputs from the second control loop, speed error values, and ambient conditions.

Patent CA-2560681-A1 (CA)
Inventor: KEMPKEN JENS
IPC: B22D11/00
Filed: 2006-03-03
Abstract: For various reasons, in the prior art it is considered difficult or impossible to produce steels with high manganese (Mn), aluminium (AI) and silicon (Si) contents and with TWIP (Twinning Induced Plasticity) properties by continuous casting. The reasons cited include low strength of the strand shell during solidification on account of extensive micro-segregation of Mn, high strength at lower temperatures, reactions of the aluminium in the steel with the casting powder, macro-segregations, depletion of the alloying elements in the surface region and oxidation of the grain boundaries during the reheating of slabs in the pusher furnace. Therefore, the invention proposes that, by successive process steps, lightweight structural steel with a predetermined chemical composition of up to 27% Mn, 1 to 6% AI, 1 to 6% Si, < 0.8% C, remainder Fe and accompanying elements, be cast on a thin-slab casting machine (1 ) (d <= 120 mm) using suitable casting powders, then immediately after the solidification slabs (3) be severed from the endless strand (2) and that temperature equalization be carried out during continuous passage through an intermediate furnace (4) and then the slab (3) be directly hot-rolled without intervening cooling.

Patent CA-2565278-A1 (CA)
Inventor: NELSON FREDERICK WILLIAM
IPC: B62D6/00
Filed: 2006-10-23
Abstract: A direction determination system particularly useful with a retrofit automatic steering system compares the rate of change of vehicle yaw rate and the rate of change of the steering wheel position. A determination of the direction is made by comparing the sign of the steering wheel angle change and the sign of the yaw rate change. The GPS course can be monitored after the direction has been determined to provide a more rapid response to changing direction. A change in direction is indicated when the vehicle speed transitions to zero and the GPS course generally reverses. Even when the direction is known, the steering wheel angle and yaw rate changes can be monitored to verify that the direction indication is correct.
