Abstract: The invention relates to a protocol for exchanging data between applications of a portable multi-application object, such as a microprocessor or smart card. An internal communications interface is implanted in the nonvolatile memory of the smart card. Given a message sending command and message reception command, a source application attribute (E-ID) is assigned a) to an application, and a target application attribute (R-ID) is assigned b) to at least one other application. The exchange of information messages (MSG) c) is done between source and target applications by means of the communications interface used as an intermediary. The invention is applicable to the management of portable multi-application objects, such as processor cards, PCMCIA cards, or the like.

Abstract: This invention relates generally to multiple systems capable of linking between systems, wherein one system may provide services to another linked system. More particularly, the present invention relates to an establishment or termination of a link between systems dependant upon whether a predefined minimum level of quality of service can be provided by one system to the other linked system. Without limitation, the application software of a first system may be linked to an interface of a second system, wherein the link between the application software and interface is established if the interface is capable of providing a minimum quality of service defined by the application software.

Abstract: A method and apparatus for performing actions while selecting objects on a user interface display. A user may select a first item in an area of a display controlled by a first process and drag that item to a second area on a display controlled by a second process. The second process may negotiate with the first process to provide certain data types, and based upon those data types, the second process will determine a list of actions in hierarchical fashion which may be performed upon the data. Such actions may include, but are not limited to, printing, sending electronic mail, and performing other actions in the computer system. Alternative and primary actions may also be specified by a user, such as by selecting various keys on a keyboard or other input device. Further, a user may specify that the second process display a list of actions which may be performed upon the selected item and allow the user to select an action from a list.

Abstract: The present invention concerns interprocess communication systems consisting of an arbitrary number of homogeneous or heterogeneous physically connected units, where a central unit executes at least one central process—called Central Process—and at least one of the units executes peripheral process(es), which are connected to the Central Process via at least one standing logical bidirectional connection. The Central Process assigns logical identifications to the connections of the peripheral processes. Using these logical identifications, peripheral processes can communicate independently of the physical units with selected peripheral processes or connections. Peripheral processes of the same kind can be exchanged transparently for other peripheral processes. Peripheral processes can maintain parallel connections to multiple Central Processes and Central Processes can be linked directly or indirectly via links to arbitrary hierachies or topologies.

Abstract: A method for transparently handling messages originating from local shared memory and from an external source. A device driver allows the local sender to identify and wake up a waiting receiver task thread, simulating a packet arrival hardware interrupt. Upon awakening, the receiver task thread examines both shared memory and hardware message queues. The method can use a software routine that simulates handling of an occurrence of a hardware interrupt. The method invokes a local notify system service module that passes a window number identifying a receiving task. The method invokes a wake thread module that passes awakens a thread associated with the window number, and examines the shared memory buffer for receipt of the local source message. The method then copies the local source message from the shared memory buffer to the receiving task.

Abstract: Initially, a SMI trap detects an application accessing a memory location associated with a physical hardware device. The SMI trap receives the device address for the address bus and compares that address with memory addresses for hardware devices being virtualized by virtual device simulators. If the address matches an available virtual device, the SMI caches the address, hooks and caches the corresponding IO instruction for the memory address and issues a SMI. A SMI handler receives the SMI and determines which virtual device simulator to call. Once activated by the SMI handler, the virtual device simulator interacts with the application and then returns control to the processor.

Abstract: With better knowledge of the behavior of objects in a running application, it is possible to improve execution environment decisions that affect management of such objects. For example, if available, object lifetime statistics could be employed in decisions that affect how and where objects are placed, e.g., on allocation or during operation of automatic dynamic memory management facilities such as a garbage collector. Typically, instrumenting all objects to sample lifetimes or other characteristics would impose an impractical level of overhead. We present a technique for dynamic sampling of a subset of allocated objects that incurs low runtime overheads. Coupled with automatic memory management or collection facilities, this technique allows us to improve the efficiency of a collector by segregating objects, sampled and non-sampled alike, based on observed characteristics such as object lifetime. The sampling techniques facilitate tracking of many kinds of object information.

Abstract: An operating system registry contains multiple “identities.” One of these identities is designated the current identity. An application executing on a multitasking computer system uses information stored in the current identity to configure the application, for example to provide a user-specific user interface. When an application opens, it registers with an identity manager using objects known as “connection points.” To switch identities, a user supplies the name of an identity to switch to. The identity manager then uses the registered connection points to query each of the applications for permission to switch identities. If all the registered connection points grant permission to switch identities, then the identity manager switches the current identity by changing information in the registry. The identity manager then notifies all applications, via their registered connection points, that a change to the registry has been made so that the applications can take appropriate action.

Abstract: Server-side control objects corresponding to client-side user interface elements are created in a control object hierarchy. Properties of the control objects may be data bound to properties of a server-side data source (e.g., a server-side database). Hierarchical data binding relationships are established between properties of control objects and properties of a data source. Template declarations are used to define the configuration of binding container objects that correspond to data objects in the data source. An iterating control object determines the number of data objects in the data source increase according number of binding container objects. A simple data binding types include without limitation: (1) unidirectional data binding from the data source to a control object; (2) unidirectional data binding from a control object to the data source; and (3) bidirectional data binding between a control object and the data source.

Abstract: A system and method for facilitating attachment of a communication interface device driver to multiple logical devices defined on a single physical communication interface device. For each attachment procedure, an identifier of the affected physical device is read and a corresponding device soft state structure is located (or created, if one does not exist). For each attached logical device, a counter of the number of attachments for the physical device is incremented, and the device information pointer and instance identifier assigned to the logical device are noted. When the final logical device is attached, the physical device can be initialized. The device information pointer for a selected logical device (e.g., one having a particular binding name) is used as a parameter in one or more DDI functions.

Abstract: Methods and components are provided which ensure both the improved use of network resources and adequate performance of best effort (BE) traffic by intelligently distributing the BE traffic demands at connection level with corresponding scaling weights, and without reserving bandwidth. A weighted sum of the best effort (BE) class connections (or LSPs in MPLS context) in a link is used as a path selection criterion, where each BE connection is weighted by its service volume. Path selection for a requested BE service volume is performed by creating a virtual topology in which all links in a network have weighted BE metrics updated to include the effects of the requested BE service volume, and identifying a best path through the virtual topology taking into account the weighted BE metrics.

Abstract: A method of marshalling on a computer communication network makes it possible to marshall a data object from a programming language used by a data processing application to a communication language which can be used by a communication protocol of the computer communication network. This marshalling method comprises the following steps: reading (E1) a data field included in the data object; substituting (E5-E7), for the data field, a computer address associated with the data field when the structure of the data field is complex; and storing (E5-E7) said computer address associated with the data field in a table of associations (T). Use notably for transferring data objects and executing remotely a function on a data object.

Abstract: An invention is disclosed that provides a mechanism for exposing to user mode applications the features and information enabled by the Advanced Configuration and Power Interface (“ACPI”) specification. The present invention provides a generic mapping driver that executes in kernel mode, and that makes calls to the ACPI driver accessible by user mode applications. The mapping driver may be a part of a management instrumentation system, such as the Windows Management Instrumentation (“WMI”) system. The WMI system provides an interface through which instrumented components, such as hardware devices, can provide information and notification to management applications in user mode through a consistent management information store. The mapping driver provides access to the ACPI system from the WMI management system.

Abstract: A system for client/server translation and execution of non-native applications. Service requests within non-native (e.g. 16-bit) applications are translated to call 32-bit equivalents within a native (e.g. 32-bit) operating system. Both non-native and native server process share a library providing native program services. As a result of this translation, non-native applications are integrated into the native operating system, and can communicate and pass data to other non-native applications, and other native applications executing within the native client/server operating system.
