摘要:
A seamless solution transparently addresses the characteristics of nomadic systems, and enables existing network applications to run reliably in mobile environments. A Mobility Management Server coupled to the mobile network maintains the state of each of any number of Mobile End Systems and handles the complex session management required to maintain persistent connections to the network and to other peer processes. If a Mobile End System becomes unreachable, suspends, or changes network address (e.g., due to roaming from one network interconnect to another), the Mobility Management Server maintains the connection to the associated peer task—allowing the Mobile End System to maintain a continuous connection even though it may temporarily lose contact with its network medium. An interface-based listener uses network point of attachment information supplied by a network interface to determine roaming conditions and to efficiently reestablish connection upon roaming. The Mobility Management Server can distribute lists to Mobile End Systems specifying how to contact it over disjoint networks.

The temperature mapping balloon of the present invention provides a device for locating inflammation and increased metabolic activity associated with conditions such as vulnerable plaque, by mapping temperature of a body lumen, such as an artery or blood vessel. The temperature mapping balloon comprises a balloon with a thermal mapping coating disposed on the inside or outside of the balloon. The thermal mapping coating can be a thermochromic coating that changes color in response to temperature or a sensor coating comprising a plurality of temperature sensors.

摘要:
A technique is described for facilitating block level access operations to be performed at a remote volume via a wide area network (WAN). The block level access operations may be initiated by at least one host which is a member of a local area network (LAN). The LAN includes a block cache mechanism configured or designed to cache block data in accordance with a block level protocol. A block level access request is received from a host on the LAN. In response to the block level access request, a portion of block data may be cached in the block cache mechanism using a block level protocol. In at least one implementation, portions of block data in the block cache mechanism may be identified as “dirty” data which has not yet been stored in the remote volume. Block level write operations may be performed over the WAN to cause the identified dirty data in the block cache mechanism to be stored at the remote volume.

Embodiments of the present invention relate to a method and apparatus for mixing additives into a fluid fuel at a predictable concentration. The method comprises: taking a sample of the fuel; mixing the additive into the sample in metered proportions; testing the sample to determine that the correct amount of additive is present; storing the remaining fuel until it is time for the fuel to be used; and mixing the additive into the remainder of the fuel in the same metered proportions.
