Title: Transmitting system for small-sized vehicle
Inventor: KIHARA TERUO
IPC: B62M7/02
Filed: 1999-11-12
Abstract: In a transmitting system for a small-sized vehicle in which a crankshaft of an engine and an input shaft of a multi-stage transmission are connected to each other through a fluid transmitting device, a shifting clutch is interposed between the crankshaft of the engine and the multi-stage transmission in a series relation to the fluid transmitting device. A lock-up clutch is interposed between a pump impeller and a turbine impeller of the fluid transmitting device. Thus, when the multi-stage transmission is to be shifted, the shifting operation can be conducted lightly, in spite of a creep phenomenon of the fluid transmitting device, by bringing the shifting clutch into an OFF state. Moreover, during cruising of the vehicle, the slipping of the fluid transmitting device can be inhibited by the OFF state of the lock-up clutch to enhance the transmitting efficiency.

Title: Establishing bi-directional communication sessions across a communications network
Inventor: GIBSON MARK ROBERT
IPC: H04L12/56
Filed: 2000-09-29
Abstract: On receipt of a request for a communication session over a communications network, such as an Internet Protocol communications network, a path for the session is established. In a preferred example the communications network is an MPLS network and the method uses a modified version of the SIP messaging protocol. Bandwidth along a chosen path is reserved and a messaging protocol such as  CR-LDP used to establish this reserved path for the communication session. Internet protocol and MPLS communications networks typically only support uni-directional flows. Several methods for establishing bi-directional communication sessions over Internet protocol communications networks that use MPLS connections are described. This is particularly useful for telephony applications using Internet protocol communications networks.  In a preferred example, the established connection provides a guaranteed level of quality of service.
