Controlled devices according to a device control model maintain a state table representative of their operational state. Devices providing a user control point interface for the controlled device obtain the state table of the controlled device, and may also obtain presentation data defining a remoted user interface of the controlled device and device control protocol data defining commands and data messaging protocol to effect control of the controlled device. These user control devices also subscribe to notifications of state table changes, which are distributed from the controlled device according to an eventing model. Accordingly, upon any change to the controlled device's operational state, the eventing model synchronizes the device's state as represented in the state table across all user control devices.

A system, method, and computer program product for synchronizing events between a mobile device and a server are described herein. In an embodiment, the method operates by detecting events to be synchronized between a source and a target, wherein the source and target are one of either a mobile device or a server. The method comprises deducing activities that occurred in order to create the detected event, reading data records corresponding to the deduced activities, and creating packets of operations needed to recreate the deduced activities on the target. The method further comprises queuing the packets of operations and data records and receiving event synchronization results at the source after the queued packets of operations have successfully executed on the target, wherein the synchronization results include a synchronization status and a unique record identifier identifying the event. In an embodiment, personal information manager (PIM) events are synchronized.

A method of deinterleaving parameter descriptor word (PDW) data includes parallel scoring of pulses in an a posteriori search for associating of pulses based on proximity within a multi-parameter problem space.

The associating utilizes at least one of a plurality of parallel computation modes, parallel tasks to operate on separate data fields, and multi-threading or multitasking that can implement one of parallel and configuration-overlaid operation, synchronized by events.

Disclosed is a multi-task-based discrete event parallel simulation and time synchronization method. The method comprises: setting a plurality of event managers, wherein each group corresponds to an event manager; synchronizing a plurality of entities in the plurality of event managers by using the only time manager; sending, by each event manager, a time synchronization request to the time manager; traversing, by the time manager, the event managers to select an event manager having a minimum execution time and a highest priority as a global push standard, actively pushing the current simulation time to the time, and notifying the corresponding event manager to be ready to execute the event; and upon completion of event execution, sending, by the event manager, a time synchronization request to the time manager again. According to the present application, a plurality of parallel threads run, thereby preventing the case where the single thread simulation fails to fully use the hardware resources, improving the simulation running efficiency, ensuring that the time management and the synchronization overheads are function calling-level overheads, avoiding cross-progress communication overhead, and improving the time management efficiency in simulation.

A computing device may rely on GPS and IR communication to determine its current location. The limits of GPS may prevent it from reliably providing location data to the computing device in a variety of situations such as in downtown metropolitan areas, geographic regions with thick canopies, in buildings, and the like. As a result, a second communication technique may also be used to provide location data to the computing device. For example, an IR transmitter may transmit location data to the computing device which, in turn, uses the location data to identify its current location. In addition, the computing device may receive or transmit supplemental data using the second communication technique for, e.g., synchronizing the computing device to a real-time event happening at the identified location or providing the location of the device to a central computing system.

The comparator compares the stripped information against an event count. The instruction types include: a relative type indicating execution at some event occurrence subsequent to the present cycle; a direct type indicating an absolute event occurrence count for execution; and a event range indicating a range of event occurrences wherein execution is valid.

A method and system where a plurality of ECU is rapidly executed while avoiding deadlock by performing conservative event synchronization. The simulation system is provided with 4 layers, namely a processor emulator which is an ECU emulator, a plant simulator, a external peripheral scheduler, and a mutual peripheral scheduler. The external peripheral scheduler performs advanced execution of the plant simulator only during processor emulator reaction delay time (or the time until the next event). The notification to perform advanced execution of the processor emulator is provided until the actual plant simulator stop time. The mutual peripheral scheduler provides notification to the processor emulator to perform advanced execution only during communication delay timing between processor emulators (or the time until the next event). The processor emulator conservatively processes until the earliest time of the notification times. Each peripheral proceeds with processing until the earliest time of the accepted events.

The synchronization setting may indicate that a corresponding event in the second datastore is to be synchronized with the event in the first datastore, or that the event in the first datastore is to be synchronized with the corresponding event in the second datastore, or the synchronization setting may indicate that the first datastore obtains from the second datastore an update to the information of the event, adds the update to the event, and synchronizes the event based on the updated event.

Redundant systems are often provided with identically mounted processor boards which function according to a lockstep operation. The basic condition for the implementation of a lockstep system is the deterministic behaviour of all of the constituents contained in the board, such as CPUs, chip sets, main memory etc. According to the invention, deterministic behaviour signifies that said constituents supply identical results at identical times, in an error-free case, when the constituents receive identical stimuli at identical times. Deterministic behaviour also presupposes the use of interfaces in clock-controlled synchronism. Asynchronous interfaces cause a certain temporal indeterminacy in the system in many cases, whereby the entire synchronised behaviour of the system cannot be maintained. In order to thus be able to carry out a lockstep operation, the invention relates to a method for the synchronisation of external events which are supplied to a processor (CPU) and influence the same. The external events are intermediately stored accordingly and the processors are presented at identical points in the execution of commands. Problems which are created by the capacity of modern processors to execute commands in parallel are avoided by the fact that the parallel execution of the processors is stopped before the desired point in the command execution is reached and said point is then reached exactly in the single step mode.

The invention discloses an event synchronization method, an event synchronization system, a client and a server. The embodiment of the invention comprises the following steps of: transmitting a latest data acquisition request; receiving an event identifier from the server by socket connection with the server; and matching a monitor for monitoring an event of the event identifier according to the received event identifier, calling a callback function corresponding to the event, and executing a synchronization operation indicated by the callback function. The embodiment of the invention can timely return corresponding data to the client, improves the efficiency of the client and the server because the client is not required to set a timer to periodically repeatedly transmit requests to the server, and avoids user experiences with unfinished long connection loading and influence on the displaying of a browser of the client.

A method and apparatus are provided for producing full synchronization of a digital file with a live event. Using time-based cues such as musical beats, the live event is time mapped. The video file to be synced is measured in frames per second is then translated from its frames per second original time code into the time code of the live event in beats per minute making it possible to measure the playback rate of the source media file in the same units of measurement as the live event. The result is a playback mechanism that allows for more precise real time playback rate corrections by an operator by providing a visible cue so they can better keep the source media synced with the live event, even if there are real time tempo variations in the live event.
