Presented is a system and method for monitoring events derived from a computer target application presentation layer including the steps of providing, independent of recompiling the target application's source code, a script running at a level within the target application. The script scans run-time instantiations of objects of the target application, and allocates structures in real-time to the object instantiations. These allocated structures are adapted to create a reflection of the target application structure, which is used along with detected object instantiations that match a predetermined object structure to capture a portion of an environmental spectrum of the detected object. Further, the system can process state machine events occurring on at least one of a server machine and a client / localized machine, correlate the state machine events with the environmental spectrum, and deduce a user experience based on the correlated state machine events.

A method of process, industrial, environmental or other control includes executing a first sequence of instructions in a first process (or thread) and executing a second sequence of instructions in a second process (or thread) that is loosely coupled with the first. States of the first and second processes are compared following their respective completions of the first and second instruction sequences. The comparison can cover registers, memory, flags, interrupts, tasks, and / or events in each of the respective processes. Execution of further instruction sequences by either process is delayed pending a favorable comparison of the process states. If the process achieve comparable states, the first process can take up execution of a third sequence, while the second process takes up execution of a fourth sequence. In the event that one of the processes does not complete its respective instruction sequence within a set period of time, or if the process states do not otherwise favorably compare after execution of the respective sequences, the method calls for signaling an error. A device for process, industrial, environmental or other control operates in accord with such a method.

The process state of a chamber after a maintenance procedure can be monitored in-situ in order to ensure that the chamber is ready for processing, while minimizing waste and downtime due to aftereffects of the maintenance procedure. The composition of a bulk plasma in a process chamber can be analyzed using an analytical tool to capture the emission spectrum of the plasma. The spectrum can be analyzed to generate a model of the current chamber conditions, which can be compared to a model of ideal chamber conditions using a statistical analysis approach such as multivariate primary component analysis. If the current and ideal models match to within a set confidence level, the chamber conditions are acceptable for processing devices, and any processing of cycling workpieces or other plasma-cleansing processes can be stopped.

The present invention saves all process state, memory, and dependencies related to a software application to a snapshot image. Interprocess communication (IPC) mechanisms such as shared memory and semaphores must be preserved in the snapshot image as well. IPC mechanisms include any resource that is shared between two process or any communication mechanism or channel that allow two processes to communicate or interoperate is a form of IPC. Between snapshots, memory deltas are flushed to the snapshot image, so that only the modified-pages need be updated. Software modules are included to track usage of resources and their corresponding handles. At snapshot time, state is saved by querying the operating system kernel, the application snapshot / restore framework components, and the process management subsystem that allows applications to retrieve internal process-specific information not available through existing system calls. At restore time, the reverse sequence of steps for the snapshot procedure is followed and state is restored by making requests to the kernel, the application snapshot / restore framework, and the process management subsystem.

Incremental single and multiprocess checkpointing and restoration is described, which is transparent in that the application program need not be modified, re-compiled, or re-linked to gain the benefits of the invention. The processes subject to checkpointing can be either single or multi-threaded. The method includes incremental page-boundary checkpointing, as well as storage checkpointing of data files associated with applications to ensure correct restoration without the need to restore files for other application programs. Incremental and full checkpoints are asynchronously merged to ensure proper operation while reducing checkpointing delay. By way of example a user-level programming library is described for loading into the address space of the application in conjunction with a loadable kernel module (LKM) or device driver used to capture and restore process state on behalf of the application. These techniques are particularly well suited for use with high-availability (HA) protection programming.

This invention teaches a quality assurance system for additive manufacturing. This invention teaches a multi-sensor, real-time quality system including sensors, affiliated hardware, and data processing algorithms that are Lagrangian-Eulerian with respect to the reference frames of its associated input measurements. The quality system for Additive Manufacturing is capable of measuring true in-process state variables associated with an additive manufacturing process, i.e. those in-process variables that define a feasible process space within which the process is deemed nominal. The in-process state variables can also be correlated to the part structure or microstructure and can then be useful in identifying particular locations within the part likely to include defects.

In a radio communication system that performs HARQ (Hybrid Automatic Repeat request), a mobile station returns the HARQ process state of the mobile station to the free state by the reception of ACK. In this state, the mobile station, upon receiving from the scheduling base station an SA (scheduling assignment) for assigning resources for retransmission, transmits a transmission process state notification reporting that the mobile station is in the free state when the mobile station does not have new data to be transmitted. The base station therefore recognizes that the mobile station is in the free state and returns the HARQ process state of the base station to the free state and halts the assignment of resources to the mobile station.

A technique for managing process state information involves pushing process state information from the kernel space to the user space in the event of an application crash and generating a core file at the user level instead of at the kernel level. Handling the process state information at the user level instead of at the kernel level provides more flexibility in the generation and management of a core file as compared to systems that use kernel code to generate and manage the core file. A core dump application at the user level can be programmed to forward the core file to another system that has permanent storage capacity available. Additionally, the core dump application can be programmed to compress the process state information and / or to extract only certain information from the process state information while generating the core file.

After the route server collects the topology state information of each relay node, quantum cryptography network topology state information of a next topology refresh cycle is generated and sent to all the relay nodes of the quantum cryptography network. According to the quantum cryptography network topology state information obtained from the route server, a target relay node is calculated and determined to be a next skip route of communication data of a random other relay node according to a shortest path law through each relay node.

A method and apparatus allow a programmer to repeatedly debug a program from the same starting point. The entire process state of the process can be saved at any time in the course of a debugging session to a disk file, called the checkpoint file. Now registers or memory may be modified, if necessary, and the program may be brought back to the same starting point where the state had been previously saved by resuming from the checkpoint file. The method and apparatus allow the state of all the programs to be saved multiple times and resumed from any one of those states. The debugging of a problem is considerably facilitated by not having to start from scratch to debug the problem as the last saved state of the program can be used to start the debugging.
