摘要： A system and methods are disclosed herein for modeling a mechanical system having body elements movable in at least two dimensions in a graphical modeling environment. The system and methods described herein allow constraints on body elements movable in at least two dimensions in the mechanical system to be generalized and represented by a single block in the graphical modeling environment. The system and methods described herein simplify the modeling of a mechanical system by allowing a user to construct a definition of generalized constraints through a connectivity table. Thus, it is possible to model a mechanical system in a graphical modeling environment with less than all the body elements represented by blocks in a graphical model.

摘要： A mechanism to dynamically vary the amount of delay for an event-generated function call is discussed. The event causing the generation of the function call may be a signal-based event, function call event or some other type of event. A function call generating delay component is inserted into a DES model and dynamically adjusts the amount of delay to apply prior to generating and transmitting the function call to an intended target component. The function call generating component reads a value from an input port in determining the amount of delay. The identified value at the input port may be a signal value or an attribute associated with an event entity received at the port.

摘要： A method of preventing use of an illegally copied optical medium comprises the step of identifying the media type of the optical medium to determine whether the optical medium is an original version or an unauthorized copy. If the media type indicates that the optical medium is an original version, use of the optical medium is not prevented. If the media type indicates that the optical medium is an unauthorized copy, use of the optical medium is inhibited. The media type can be identified by reviewing a medium-type code field contained in a mode parameter header of the optical medium, which corresponds to the media type of the optical medium, and is a feature integrated into the media that cannot be copied.

摘要： The present invention provides a system and method for detecting communication error among multiple nodes in a concurrent computing environment. A barrier synchronization point or regions are used to check for communication mismatch. The barrier synchronization can be placed anywhere in a concurrent computing program. If a communication error occurred before the barrier synchronization point, it would at least be detected when a node enters the barrier synchronization point. Once a node has reached the barrier synchronization point, it is not allowed to communicate with another node regarding data that is needed to execute the concurrent computing program, even if the other node has not reached the barrier synchronization point. Regions can also be used to detect a communication mismatch instead of barrier synchronization points. A concurrent program on each node is separated into one or more regions. Two nodes can only communicate with each other when their regions are compatible. If their regions are not compatible, then there is a communication mismatch.

摘要： The present invention provides a method and system for building an executable using only the necessary source modules or a reduced set of source modules. The complete list of necessary source modules can be determined by checking for dependency of any already identified necessary source modules. Hence, if any of the source modules belongs to a library, the entire library will not need to be compiled in order to use any necessary source module to build the executable. The present invention has the advantage that the executable takes shorter time to build and the executable is smaller in memory size so that it is easier to be ported to a target system. The present invention may also be used to minimize or reduce the memory needed to load a model so that only the elements/blocks that are used in the model are loaded into memory when a model loads. The present invention may further be used to minimize or reduce efforts in validating a model by creating a new library containing only the library elements/blocks that are used in the model, so that it is easy to identify which library elements/blocks need to be validated.

摘要： A system and method for converting analog signals to digital signals minimize the latency of the analog to digital conversion for real-time systems. The conversion system and method implements the hardware of an analog to digital converter input/output (I/O) board and a software-based I/O-driver in an expansion bus. The hardware of the ADC I/O board executes free-running conversion of an analog signal into digital form and stores the converted values in a first level of a buffer having two levels. Previously stored converted values are pushed to the second level of the buffer when a new value is written to the first level. The I/O driver then retrieves stored values from the second level of the buffer when needed by the real-time system and gates the buffer to prevent pushing during retrieval of values from the second level.
