摘要:
A method and system for facilitating digital commerce using a secure digital commerce system is provided. The secure digital commerce system is arranged according to a client/server architecture and includes a modularized DCS client and DCS server. The DCS client and the DCS server are incorporated into an online purchasing system, such as a virtual store, to perform the purchase and online delivery of electronic content. The DCS client includes a set of components which include a secured copy of the merchandise and various components needed to license and purchase the merchandise and to unsecure and process (e.g., execute) the licensed merchandise. The DCS client communicates with the DCS server to download the components onto a customer's computer system and to license and purchase a requested item of merchandise. The DCS server, which includes a content supplier server, a licensing and purchasing broker, and a payment processing function, supplies merchandise-specific components and licenses the requested item of merchandise by generating an electronic certificate. The electronic certificate contains license parameters that are specific to the requested merchandise and an indicated purchasing option. Once a valid electronic license certificate for the requested merchandise is received by the DCS client, the merchandise is made available to the customer for use in accordance with the licensing parameters contained in the electronic license certificate.

A method and system for injecting code into an existing HTML document that enables the conditional generation and incorporation of an injectable component is provided. The injection mechanism provided enables a user to display an add-on user interface component within a web page using a technique that is transparent to the normal processing within a browser application. The injection mechanism installs interceptor code as a proxy server between a client browser and a server. The interceptor code monitors all HTTP messages sent from the client browser and injects code into each HTML document that is sent from a server to the client browser. The injected code when executed by the client browser conditionally inserts HTML code into the received HTML document. The inserted HTML code is then used by the client browser to generate a new component, for example a user interface component. The code injected by the interceptor code is dependent upon the type of the browser and whether certain tags are present in the received HTML document. In addition, the code may be written in a script language, such as Javascript or VBscript.

A wind-powered apparatus includes a series of vertically extending transversely curved foils carried in a support and movable longitudinally of the support from a furled condition, where the foils are bunched closely together and present a minimum surface area to the wind, to an unfurled position where the foils are uniformly spaced along the support. The support can be rotated to take advantage of the wind direction, and the foils themselves can be rotated in unison to one side or the other. The various movements of the foils are powered by suitable drive mechanisms which may be remotely controlled.

A block level data snapshot system uses agents to convert block level file commands from devices such as computer workstations intended for block level devices such as hard disks. The block level file commands are converted into instructions for a node based snapshot data system for taking snapshots at the block level. By converting the block level file commands into instructions suitable for the node based snapshot system, snapshots are able to be taken at the block level, which allows for disk storage savings and speed enhancements. One resultant feature is that the block level data snapshot system can be used as a block level storage device for one or more workstations thus allowing relatively simple integration of a snapshot system with existing workstations.
摘要:
A method and system for creating a snapshot of data. The snapshot system creates a snapshot of data that is hierarchically organized, such as the data of a file system. When a snapshot is to be created, the snapshot system copies the root node of the hierarchical organization to a new root node that points to the same child nodes as the copied root node. This new root node becomes the root node of the snapshot data. When a current node is subsequently modified, the snapshot system replaces each ancestor node of that node that has not yet been replaced with a new node that has the same child nodes as the replaced node. The snapshot system also replaces the node to be modified with a new node that points to the same child nodes of the replaced node.

A method and system for enabling a page description provided by a source server to perform additional behavior provided by a portal server. The page description (e.g., an HTML document) is associated with one or more items (e.g., a product). The enabling system executes at the portal server and receives a selection of the page description (e.g., a URL) from a client computer. The enabling system then retrieves from the source server the selected page description. The enabling system adds to the retrieved page description a user interface element that describes an action to be performed so that the additional behavior (e.g., placing an order for the product) can be performed for the associated item. The enabling system may also redirect to the portal server the navigation references of the retrieved page description so that all navigation based on the page description is routed through the portal server. When the enabling system intercepts these redirected navigation references, it can then retrieve and enable the referenced page description.
摘要:
A one-part, air-activatable, polymerizable composition comprising:(a) at least one free-radically polymerizable monomer, and(b) an activator system for effective polymerization of the free-radically polymerizable monomer, said activator system comprising at least one auto-oxidizable compound of a formula which includes the structure I: ##STR1## where x is 0 or 1, and where the lines representing unfilled valencies indicate bonds to carbon, hydrogen or hetero atoms, alone or in combination with a weak acid;with the proviso that:when x=0, the nitrogen atom in structure I is not bonded to a second nitrogen atom;and when x=1 there is a structure I in the compound in which the >C.dbd.C>moiety does not form part of a phenyl ring;with the proviso that the composition does not contain a peroxide, or a peroxide precursor which produces peroxide in the absence of air or any ingredient which is a significant source of radicals in the absence of air.Preferred auto-oxidizable compounds are selected from the group consisting of partially hydrogenated pyridines, condensation products of cyclic ketones and ureas, Schiff's bases, indoles, pyrroles, imidazoles, piperazines, carbazoles, tetrahydroquinolines, and substituted derivatives thereof, particularly dihydropyridines.The composition may also contain a soluble ionic salt, particularly a cobalt or iron salt.The compositions as described are stable on storage in the absence of air, are activated by exposure to air, and will then cure in either the presence or absence of air.
