Abstract: An Internet Service Provider provides IPv6 connectivity to a customer without requiring that the customer upgrade its network containing IPv4 components. The Internet Service Provider makes at least one point of presence including at least one IPv6 Connect Agent available to customers. The Internet Service Provider allows a customer's IPv6 enabled node located within the customer's network containing IPv4 components to automatically discover an IPv6 Connect Agent. The Internet Service Provider facilitates IPv6 communication between the customer's IPv6 enabled node and the discovered IPv6 Connect Agent, across the customer's network containing IPv4 components.

Abstract: The invention improves tire flat spotting by providing a bead assembly that has bead filler elements disposed outside the body cords so that the turn up portion of the ply of body cords is disposed immediately back against the main portion of the ply of body cords above the bead core. This carcass structure increases the stiffness of the lower sidewall and decreases the flat spotting experience by the tire. In one embodiment of the invention, a reinforcing ply is wrapped around the bead filler elements to further increases the stiffness of the lower sidewall. In another embodiment, a bead filler element is disposed inside the body cords so that an air pocket is not formed in the carcass during the manufacturing process.

Abstract: A pneumatic tire includes a body having a plurality of main body cords. The tire includes an upper section above the maximum section width and a lower section below the maximum section width. The modulus of the body cords is configured to be larger in the lower section than in the upper section. This modulus ratio decreases the rolling resistance of the tire. The increased modulus in the lower section is achieved by providing a body cord insert wrapped around the bead core and bead filler. The ends of the body cord insert are disposed against each other so that the entire bead filler is surrounded. The body cord insert extends substantially over the entire lower section of the tire.

Abstract: According to the present invention, there is provided a data transfer system using mobile IP in which transfer interruption is not caused even if an MH moves between FNs. A MAC bridge connected between FNs includes means responsive to an address registration request issued by an AP, for storing a combination of a MAC address of the MH and a receiving port, in a filtering DB; means for registering a relation of association of an address of a terminal accommodated in an FN with a connection port of an FN in which the terminal is accommodated, in the filtering DB; and means for referring to the filtering DB on the basis of the destination address of a frame input to each port, and transferring the frame to a predetermined port on the basis of a relation of association of the address with a port identifier.

Abstract: A pneumatic tire includes a body having a plurality of main body cords. The tire includes an upper section above the maximum section width and a lower section below the maximum section width. The modulus of the body cords is configured to be larger in the lower section than in the upper section. This modulus ratio decreases the rolling resistance of the tire. The increased modulus in the lower section is achieved by providing intermediate body cords disposed between the main body cords. In another embodiment, the increased modulus is achieved by changing the material and/or size of the cords in the lower section.

Abstract: A pneumatic tire includes a body, a belt package, and a tread package. The tire includes a layer of rubber disposed between the body and the tread package. The layer of rubber creates a thickness of between about 0.5 millimeters and about 1.5 millimeters between the cords in the body and the cords in the belt package. The layer of rubber is fabricated from a rubber having a stiffness greater than the rubber in the body of the tire. This configuration provides a tire having improved cornering coefficient, reduced vibrational levels, and less coarse road noise with only a small increase in rolling loss.

Abstract: The output level (vibration level) of vibration of a portion below the spring of a vehicle detected by a vibration sensor mounted to the portion below the spring of the vehicle is frequency converted by frequency analyzing means 14F to obtain the frequency spectrum of the vibration level and an operation is carried out on at least two vibration levels at different frequency bands of the obtained frequency spectrum by vibration level computing means 14R, and this computed value is compared with a master curve showing the frequency spectrum of vibration level stored in vibration level storage means 16S to estimate the condition of a road surface so as to estimate the running state of the vehicle.

Abstract: A method of transferring data in mobile IP of the present invention comprises the steps of: causing the home agent(HA) to store as a care-of-address of the mobile host (MH) an address of the foreign agent (FA) received from MH; causing a DNS server in the home network (HN) to demand the care-of-address of MH from HA in response to the request of the communication terminal about the IP address and the care-of-address of MH; causing HA to provide the DNS server with the care-of-address of MH upon receiving the demand; and causing the DNS server to deliver the IP address and the care-of-address of MH to the communication terminal.

Abstract: An amount of data to be distributed to each receiving terminal is dynamically controlled for each receiving terminal in response to a congestion of each of plural receiving terminals. When a determination of an RR (Reception Report) returned from the receiving terminal results in a very low rate of packet loss, an adaptive control mixer distributes communication data transmitted from a transmitting terminal to the receiving terminal without reducing the communication data. On the other hand, the determination of the RRs returned from the receiving terminals results in a high rate of packet loss, for example, 50% and 90%, respectively. In this case, the adaptive control mixer reduces, for example, 50% of the communication data transmitted from the transmitting terminal and then distributes the data to the one receiving terminal. The adaptive control mixer reduces, for example, 90% of the communication data and then distributes the data to the other receiving terminal.

Abstract: A pneumatic radial tire which is excellent in drainage and capable of reducing air-column-tube resonance sounds in circumferentially extending grooves to decrease noises. The pneumatic radial tire comprises a tread provided thereon with a groove extending circumferentially in the circumferential direction of the tire and a vibration buffer wall having essentially an identical cross-sectional shape provided near the sidewall of said circumferentially extending groove, wherein the height of the outside edge of the vibration buffer wall in the radial direction of the tire is lower than the height of the outside edge of the circumferentially extending groove in the radial direction of the tire.
