177 results about "Open architecture" patented technology

Open architecture is a type of computer architecture or software architecture intended to make adding, upgrading, and swapping components easy. For example, the IBM PC, Amiga 500 and Apple IIe have an open architecture supporting plug-in cards, whereas the Apple IIc computer has a closed architecture. Open architecture systems may use a standardized system bus such as S-100, PCI or ISA or they may incorporate a proprietary bus standard such as that used on the Apple II, with up to a dozen slots that allow multiple hardware manufacturers to produce add-ons, and for the user to freely install them. By contrast, closed architectures, if they are expandable at all, have one or two "expansion ports" using a proprietary connector design that may require a license fee from the manufacturer, or enhancements may only be installable by technicians with specialized tools or training.

Workflow system and method

A workflow system that automates work processes. The workflow system uses an open architecture to support multiple platforms and includes Application Programming Interfaces (APIs) enabling applications to communicate with a workflow engine. The workflow system supports Relational DataBase Management System (RDBMS) databases and allows routing of any kind of work (forms, images, executables). In addition, its flexible architecture is designed to facilitate changes to a workflow dynamically and to support integration with an existing infrastructure.
The workflow system links software components to enable participants to work on shared data and ensures that business processes follows predetermined rules. Each task in the process is regulated such that the appropriate people have access to the appropriate data and are instructed to perform the task at the appropriate time.
A developer can use a workflow system provided client to get an application up and running relatively quickly. The workflow system provides adapters which enables quick deployment and element flexibility. Adapters have a fixed interface which allows the Document Management System ((DMS)), Directory Services (DS) and DataBase system (DB) to be changed independent of the application in contrast to other workflow systems which tie the application directly to the (DMS), DS, and DB. The adapters allow developers to attach clients of varying types and magnitude and allows developers to mix and match application elements to better serve their application. Thus, the workflow system is not tied to any proprietary (DMS), DS, or DB.

Universal simulator for aircraft engines

The invention discloses a universal simulator for aircraft engines. The universal simulator comprises an upper industrial personal computer, a simulation measurement and control computer, a display control desk, a combination instrument case with a plurality of instrument hardware modules, an instrument extension case, a signal adaptation unit, a direct-current voltage-stabilized source and a special testing cable. The universal simulator has the advantages that mathematical models of the engines are operated by an embedded high-performance real-time operating system of the simulation measurement and control computer, so that the real-time performance and the effectiveness of simulation experiments can be guaranteed; hardware architectures for forming testing systems are standard PXI [PCI (peripheral component interconnect) extensions for instrumentation] bus open architectures, accordingly, the hardware modules of various mature PXI bus interfaces can be extended and configured according to particular testing application, and the universal simulator is high in automation degree, extensibility and compatibility and good in maintainability; the signal adaptation unit is configured with standard and universal electric connectors by means of integration, and only corresponding matched testing connecting cables need to be replaced, so that electric connection of the testing systems can be quickly reconstructed by the simulator for the engines, and requirements of platforms on the universality can be met.
