摘要:
A mechanism for negotiating a relatively transport agnostic communication protocol for use in accomplishing a distributed activity. The potential protocols subject to negotiation may be, for example, extensions to Web Services Coordination. In that case, when the initiator creates a transaction, the initiator also negotiates the desired protocol with its transaction manager. The transaction manager and any other participants in the transaction will then follow that negotiated protocol when communicating with the transaction manager. The protocol may be selected to improve performance and may be tailored to existing needs and capabilities.

The present invention extends to methods, systems, and computer program products for synchronizing ambient state among multiple transaction managers. A coordinating transaction manager establishes transaction ambient state for an application initiated transaction. The coordinating transaction manager sends and a subordinate transaction manager receives a pointer to an ambient state delegate. The subordinate transaction manager sends a request to invoke the ambient state delegate to the coordinating transaction manager in response to receiving an operation. The coordinating transaction manager invokes the ambient state delegate to format the transaction ambient state for the subordinate transaction manager. The coordinating transaction manager sends and the subordinate transaction manager receives the formatted transaction ambient state such that the subordinate transaction manager can appropriately process the operation within the scope of the transaction. The subordinate transaction manager utilizes the formatted transaction ambient state to appropriately process the operation within the scope of the transaction.

A web services namespace pertains to an infrastructure for enabling creation of a wide variety of applications. The infrastructure provides a foundation for building message-based applications of various scale and complexity. The infrastructure or framework provides APIs for basic messaging, secure messaging, reliable messaging and transacted messaging. In some embodiments, the associated APIs are factored into a hierarchy of namespaces in a manner that balances utility, usability, extensibility and versionability.

Minimizing transaction managers. A method that may be practiced in a commit tree topology including a plurality of transaction managers to manage transactions. The transactions include a set of operations that are all performed if a transaction is completed or all aborted if a transaction is not completed. The transaction managers store transaction result information to allow recovery of a transaction in case of system failure. The method includes acts for minimizing storage overhead by minimizing the number of transaction managers used to coordinate transactions. The method includes identifying a set of transaction managers. A first transaction manager is selected from among the set of transaction managers. A second transaction manager is identified from among the set of transaction managers that is always available when the first transaction manager is available. Messages are redirected from a subordinate associated with the first transaction manager to the second transaction manager.

Example embodiments of the present invention provide a mechanism for allowing developers to define new interfaces and insert custom translational code that implements these new interfaces for legacy components that otherwise cannot communicate in a web service environment. These new interfaces are then exposed to the web service client in such a way that abstracts the web service client from the legacy components interfaces. The objects that implement the new interfaces are referred to herein as “service surrogates” and the new interfaces will be commonly referred to as a, “surrogate interfaces.” These surrogate interfaces may be initialized along with an instance of the service surrogate upon startup of an application that offers the services. In addition, a dynamic web service can simultaneously run along with the service surrogate for those services that may not need the features offered by the service surrogates.

An analog to digital processor for time bounded signals. The present invention provides a processor that is capable of processing time bounded signals through a delta sigma modulator. The present invention provides a gate or premodulator to limit the input the application of a time bounded input signal to the digitizer only during the time bounds of the signal. This provides optimum filtering of both the input signal and the modulator output while preserving the benefits of the delta sigma approach.

The present invention is a mechanical lock manipulator and method of manipulating mechanical locks. There is a computer or microprocessor that controls a motor. The motor rotates the dial of a mechanical lock either clockwise or counterclockwise as directed by the computer. The computer receives an input from a transducer mounted to the lock or container. The transducer converts sounds and/or vibrations, into electrical signals. The computer collects data from the transducer and then evaluates this data and determines the opening combination for the lock.
