Abstract: A localized heating device includes a plasma deforming portion and a heating portion. The plasma deforming portion includes an inlet end having a circular hole, an outlet end having an elongated hole with a first length and a first width, and a channel smoothly connected with the circular hole and the elongated hole. The heating portion, disposed at the outlet end, includes two control covers spaced by a slot. The elongated hole and the slot being oppositely disposed with respect to the plasma deforming portion. A plasma flow provided by a plasma producing source being to enter the channel via the circular hole, then to flow through the elongated hole, and finally to reach the slot.

Abstract: Channels between routers for use in packet routing via payload inspection. The channels constitute logical connections between routers and include subjects and attributes. Publishers create channels for routing particular types of content as defined by the subjects and attributes. The publishers also create proxies and notifications on the channels. The channel definitions for routers identify packet or message structures so that the routers can locate attributes in the packets for content-based routing. The routers apply the packet attributes to filters encapsulating subscriptions in order to perform the content-based routing in the network core. The routers also locally cache content, providing distributed caching of content throughout the network core.

Abstract: Packet routing via payload inspection at routers in a core of a distributed network for use in distributing content according to quality of service guarantees. Packets contain subjects and attributes in addition to routing information. The subjects correspond with particular types of content for subscriptions, and the attributes encapsulate the data or content. The subscriptions are associated with particular quality of service guarantees or levels of service. The routers store filters corresponding with subscriptions to content. Upon receiving a packet, a router inspects the payload section of the packet containing the attributes in order to retrieve the attributes and match them to the filters for the subscriptions. If the attributes satisfies a filter, the packet is routed to the next link in accordance with the quality of service guarantee associated with that filter. If the attributes do not satisfy any of the filters injected to and stored at the router, the router discards the packet.

Abstract: A method and apparatus provide for persistent caching of methods delivered via a publish-subscribe network. At a first node, a message having data via the network is received. The data is time-marked. The data is cached in a cache memory at the first node. The message is routed to a second node using content-based routing. These steps are repeated at a second node. A router that includes modules for executing this method is provided. A publish-subscribe network that includes nodes that include modules for executing this method is provided. A computer-readable medium that includes instructions for executing this method is provided.

Abstract: Packet routing via payload inspection at routers in a core of a distributed network for use in providing alert services. Packets include subjects and attributes in addition to routing information. The subjects correspond with particular types of content for subscriptions, and the attributes encapsulate the data or content, which can include video clips from cameras at particular locations. The routers store filters corresponding with subscriptions to content. Upon receiving a packet, a router inspects the payload section of the packet containing the attributes in order to retrieve the attributes and apply them to the filters for the subscriptions to content from the cameras. If an attribute satisfies a filter, the packet is routed to the next link. If the attributes do not satisfy the filters, the router discards the packet. These routing decisions are distributed among routers in the network core.

Abstract: A registration applet embedded in a registration page of a browser program allows a user to associate a user-specified group name with a plurality of UTRLs, HTTP POST or GET requests or other network service identifiers, such that the group name designates a category of information provided by corresponding network services. An access applet embedded in an access page of the browser allows a user to select one of several previously-registered group names, and an access mode for processing responses to service requests. A processor running the access applet automatically issues parallel requests to the network services associated with a selected group name in response to entry of a command by the user.
