Abstract: A known analytical physical quantity of an analysis subject and an element level consistent mass matrix of each element are obtained by acquiring units. A bubble function is integrated for each element, and the element level diagonal mass matrix of each element is computed by substituting the value that is integrated for the element level consistent mass matrix of each element. The diagonal mass matrix for the entire analysis region is computed by the summation (superposition) of the element level diagonal mass matrices of each element and inverse matrix thereof is computed. A motion of the analysis subject is analyzed based on the known analytical physical quantity, the diagonal mass matrix for the entire analysis region, and the inverse matrix thereof.

Abstract: A discrete event system (DES) modeling environment models the occurrence of events independent of continuous model time. In a DES modeling environment, state transitions depend not on time, but rather asynchronous discrete incidents known as events. A user may customize selected parameters of a block or other component able to support at least one entity passing therethrough holding a value of arbitrary data type in a DES modeling environment. For example, a user can enable and disable ports a discrete event execution block in a discrete event execution model using a graphical user interface, such as a dialog box. Based on user-selected dialog inputs, a discrete event execution program can automatically update a specification for a block, for example, by adding ports to the graphical representation of the block.

Abstract: A data backup system comprises an emulation component and a storage device having logical storage areas. The emulation component is configured to represent a first logical storage area of the storage device, such as a solid state memory or a disk drive partition, as if it were an auto-launch device. Accordingly, a data source, such as a personal computer, will interact with the first logical storage area as if it were the auto-launch device. As some operating systems are configured to recognize auto-launch devices upon connection and automatically execute applications stored thereon, merely connecting the data backup system to a data source running such an operating system can cause a backup application stored by the first logical storage area to automatically execute on the data source to selectively back up data to a second logical storage area of the storage device.

Abstract: A method is provided for assessing whether to terminate a computer-implemented simulation of a physical experiment. Computations associated with the computer-implemented simulation that model the physical experiment are executed and to determine if a desired outcome associated with the physical experiment will occur. The results of the computations are evaluated to determine if the results indicate that the desired outcome has occurred. If the desired outcome has not occurred, periodically the results of the computations are evaluated with respect to at least one negative indication that the desired outcome is not possible and thus not likely going to occur. If the at least one negative indication is present, the computations associated with the computer-implemented simulation is terminated.

Abstract: A method and apparatus automatically determines equilibrium operating conditions of a system model. The automated method enables users of block diagram models of dynamic systems to utilize simulation to define operating conditions for linearization. The automated method further allows users to generate operating conditions during simulation instead of explicitly specifying them by hand or using trim analysis. In accordance with one example, the method of generating a linear time invariant model includes providing a system model. A user specifies at least one event at which a linearization analysis should be performed. A simulation of the system model is executed. The electronic device automatically performs the linearization analysis upon occurrence of the at least one event as the simulation is running. Output results are generated of the linearization analysis to form the linear time invariant model.

Abstract: A portable device is connected to a host system that operates according to a first industry standard architecture (e.g., a personal computer built according to the IBM Personal Computer standard). The user initiates a session in the host system using the software and data in the portable device. The user suspends the state of the session, the state is stored in the portable device, and the user disconnects the portable device from the host. The user later connects the portable device to a second host that operates according to a second industry standard architecture (e.g., Apple Macintosh™ computer). The second host boots an autoconfiguring host operating system stored in the portable device and starts a virtual machine layer also stored in the portable device. The user then resumes operation of the suspended virtual machine layer session.
