A method and apparatus for emulating VPLS within an ATM network. Provider Edge devices are configured for VPLS connections. For each pair of provider edge devices supporting the same VPLS ID, one device establishes a virtual circuit between the pair. Thus, a full mesh of virtual circuits is established between provider edge devices, and a VPLS-like service can be offered to users without having to implement MPLS. Establishing the virtual circuits within a PNNI hierarchy maybe facilitated by each provider edge device propagating through the hierarchy an information group containing an association between the ATM address of the device and a VPLS ID, so that each provider edge device learns all ATM addresses to be associated with each VPLS ID. The method of advertising ATM addresses can be applied to other services requiring a number of interconnections between provider edge devices, such as Virtual Private Networks.

A method, computer readable medium, and system for providing a mobile communication network includes dynamically forming a plurality of mobile communication devices into one or more clusters based on one or more parameters, each of the one or more clusters having a tree structure. Each of the one or more clusters are at least partially meshed together. At least one virtual identifier is dynamically assigned to each of the plurality of mobile communication devices based on the tree structure of each of the one or more clusters. The virtual identifier provides address information for routing communications between two or more of the plurality of mobile communication devices.

Prior art fuel line check valves remain closed after engine off and cool down. Diurnal heating and the resultant pressure increase in the fuel line causes fuel vapor emissions through small openings in the fuel line (e.g., at the injector tips). The invention provides a check valve for a vehicle fuel line which opens in response to engine cooling and remains open while the engine is off to relieve subsequent increasing pressure in the fuel line due to diurnal heating thereof.

A motorized ladder rack for loading or unloading a ladder on a vehicle is provided. The motorized ladder rack comprises a stationary front cradle, a pivotable and extendable rear cradle and a side rail. The rear cradle includes a motorized drive assembly which may be remotely controlled. The front and rear cradles are secured to the vehicle. The front cradle includes a support member, front and side guides removably secured to the support member and a side stop removably secured to the support member. The side rail is secured to the front and rear cradles and extends therebetween. The ladder rack is movable between a first position and a second position by activation of the motorized drive assembly.

There are provided an apparatus and an associated method for manufacturing superplastically formed structural assemblies from preforms. The apparatus includes first and second co-operable dies structured to define a die cavity therebetween for at least partially receiving the preform, at least one heater in thermal communication with the die cavity for heating the preform to a forming temperature, and at least one injector in fluid communication with the die cavity. The injector is structured for injecting pressurized gas into the die cavity to urge the preform against one of the dies to form the preform into the structural assembly. Further, at least one of the injectors is structured for injecting a quenchant into the die cavity to thereby heat treat the structural assembly while distortion of the structural assembly is being at least partially restrained by at least one of the dies.

Various exemplary embodiments are a method and related system and computer-readable medium including one or more the following: receiving a data packet; analyzing the data packet using deep packet inspection (DPI) to determine an application associated with the data packet; determining an MPLS tunnel corresponding to the application associated with the data packet; and forwarding the data packet through the MPLS tunnel. In various exemplary embodiments, the step of analyzing the data packet including examining information in layers 2 through 7 of the data packet or analyzing the data packet to match an application signature. Furthermore, in various exemplary embodiments, the method and related system and computer-readable medium also includes adding a marking to the data packet to indicate the application associated with the data packet.
摘要:
An apparatus for eliminating electricity leakage from an electronic device connected to a power supply, while the electronic device is in switched-off state or stand-by state is disclosed. The electricity leakage is the electricity consumed by at least one active component of the electronic device that remains active in the switched-off state or standby state. The apparatus comprises of a charging module connected to at least one rechargeable battery for selectively providing electricity from the power supply to the rechargeable battery while the electronic device is in switched-on state using a MCU chip and associated circuit. An isolation module is provided for isolating the power supply from the electronic device while the electronic device is in switched-off state or standby state and restoring the power supply when the electronic device is in switched-on state. A back up module connected to the rechargeable battery, providing power to at least one active component from the rechargeable battery such that at least one active component remains operational even when the electronic device is in switched-off state or standby state.
