Abstract: A powershift transmission of an engine-driven vehicle includes input and output shafts, a plurality of fluid pressure operated clutch for controlling flow of torque through the transmission and pressure control valves for controlling fluid pressure communicated to the clutches. A method of controlling an off-going clutch during a shift of the transmission includes detecting a load on the engine, as a function of the detected load, determining a slip pressure, which when applied to the clutch would cause the clutch to slip, and applying the slip pressure to the clutch. If the clutch is not slipping, the pressure applied to the clutch is reduced until relative rotation (slip) between the input and output elements of said clutch is detected. Then a pressure increase is determined, which when applied to the slipping clutch would allow the slipping clutch to continue to slip while transmitting the same torque it was transmitting before it began to slip. Finally, this pressure increase is applied to the slipping clutch.

Abstract: According to an exemplary embodiment an architecture for a new integrated TD MA system capable of carrying circuit data (e.g., voice, video, ISDN), packet data (e.g., X.25, Frame Relay, Internet, LAN), and ATM cells is disclosed. T he architecture may be used for satellite and wireless TDMA networks, for example. For this transmission formats for bursts (101), channels (130, 140) , TDMA frames (10) are defined and an adaptation layer for the three traffic types is described. In addition, the network has to carry its own management traffic and provide timing and control information to all terminals. For thi s the invention defines special bursts and along with their associated properties and formats. Each burst contains a data section which is divided into a number of channels. Each of the channels is adapted to carry protocol data units (141, 142, 143) which enable the system to efficiently allocate data according to its individual format or protocol thereby enabling maximum use of available bandwidth under prevailing communication conditions.</SDOAB >

Granted: 2006-07-18
Abstract: A router has a network topology table and a number of resource tables corresponding to network areas. In response to a user's request, one of entries of the topology table and one of the resource tables are referenced and a traversable area along the route to the destination and links of the area which satisfy a user-specified QoS value are selected. A calculation is performed on the selected links according to the Dijkstra algorithm to find a shortest path to the destination if the referenced entry indicates that the destination is in the local area of the muter. If the entry indicates otherwise, the calculation is continued until a shortest path tree is found for all area border routers of the traversable area or until the calculation terminates if that tree is not found for all such routers, and a route having an optimum QoS value is determined from the shortest path tree.
