Graphical System Design
Graphical system design (GSD) is a modern approach to designing measurement and control systems that integrates system design software with COTS hardware to dramatically simplify development. This approach combines user interfaces, models of computation, math and analysis, Input/output signals, technology abstractions, and various deployment target. It allows domain experts, or non- implementation experts, to access to design capabilities where they would traditionally need to outsource a system design expert. This approach to system design is a super-set of electronic system-level (ESL) design. Graphical system design expands on the EDA-based ESL definition to include other types of embedded system design including industrial machines and medical devices. Many of these expanded applications can be defined as "the long tail" applications. System-level design Graphical system design is an approach to designing an entire system, using more intuitive graphical software and off-the- ...

Commercial Off-the-shelf
Commercial-off-the-shelf or commercially available off-the-shelf (COTS) products are packaged or canned (ready-made) hardware or software, which are adapted aftermarket to the needs of the purchasing organization, rather than the commissioning of custom-made, or bespoke, solutions. A related term, Mil-COTS, refers to COTS products for use by the U.S. and Canadian militaries. In the context of the Federal government of the United States, U.S. government, the Federal Acquisition Regulation (FAR) has defined "COTS" as a formal term for commercial items, including services, available in the commercial marketplace that can be bought and used under government contract. For example, Microsoft is a COTS software provider. Goods and construction materials may qualify as COTS but bulk cargo does not. Services associated with the commercial items may also qualify as COTS, including installation services, training services, and cloud services. COTS purchases are alternatives to custom softwa ...

Intellectual Property
Intellectual property (IP) is a category of property that includes intangible creations of the human intellect. There are many types of intellectual property, and some countries recognize more than others. The best-known types are patents, copyrights, trademarks, and trade secrets. The modern concept of intellectual property developed in England in the 17th and 18th centuries. The term "intellectual property" began to be used in the 19th century, though it was not until the late 20th century that intellectual property became commonplace in most of the world's List of national legal systems, legal systems."property as a common descriptor of the field probably traces to the foundation of the World Intellectual Property Organization (WIPO) by the United Nations." in Mark A. Lemley''Property, Intellectual Property, and Free Riding'', Texas Law Review, 2005, Vol. 83:1031, page 1033, footnote 4. Supporters of intellectual property laws often describe their main purpose as encouragin ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
FPGA
A field-programmable gate array (FPGA) is a type of configurable integrated circuit that can be repeatedly programmed after manufacturing. FPGAs are a subset of logic devices referred to as programmable logic devices (PLDs). They consist of an array of programmable logic device, programmable logic block, logic blocks with a connecting grid, that can be configured "in the field" to interconnect with other logic blocks to perform various digital functions. FPGAs are often used in limited (low) quantity production of custom-made products, and in research and development, where the higher cost of individual FPGAs is not as important, and where creating and manufacturing a custom circuit would not be feasible. Other applications for FPGAs include the telecommunications, automotive, aerospace, and industrial sectors, which benefit from their flexibility, high signal processing speed, and parallel processing abilities. A FPGA configuration is generally written using a hardware descr ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |
OpenWire (library)
OpenWire is an open-source dataflow programming library that extends the functionality of Embarcadero Delphi and C++ Builder by providing pin type component properties. The properties can be connected to each other. The connections can be used to deliver data or state information between the pins, simulating the functionality of LabVIEW, Agilent VEE and Simulink. OpenWire is available for Visual Component Library (VCL) and FireMonkey (FMX). History The project started in 1997 as an attempt for visual design of text parsers. Later it was used for designing signal processing libraries, and was expanded to support any data type. Pins Pins form the connections between the components. OpenWire defines 4 types of pins: * SourcePin usually provides data. Can connect to one or more SinkPins and to one StatePin. * SinkPin usually receives data. Can be connected to one SourcePin. * MultiSinkPin usually receives data. Can be connected to one or more SourcePin. * StatePin usually is us ...

SPICE
In the culinary arts, a spice is any seed, fruit, root, Bark (botany), bark, or other plant substance in a form primarily used for flavoring or coloring food. Spices are distinguished from herbs, which are the leaves, flowers, or stems of plants used for flavoring or as a garnish (food), garnish. Spices and seasoning do not mean the same thing, but spices fall under the seasoning category with herbs. Spices are sometimes used in medicine, Sacred rite, religious rituals, cosmetics, or perfume production. They are usually classified into spices, spice seeds, and herbal categories. For example, vanilla is commonly used as an ingredient in Aroma compound, fragrance manufacturing. Plant-based sweeteners such as sugar are not considered spices. Spices can be used in various forms, including fresh, whole, dried, grated, chopped, crushed, ground, or extracted into a tincture. These processes may occur before the spice is sold, during meal preparation in the kitchen, or even at the ... [...More Info...] [...Related Items...] OR: [Wikipedia] [Google] [Baidu] |

DOORS
A door is a hinged or otherwise movable barrier that allows ingress (entry) into and egress (exit) from an enclosure. The created opening in the wall is a ''doorway'' or ''portal''. A door's essential and primary purpose is to provide security by controlling access to the doorway (portal). Conventionally, it is a panel that fits into the doorway of a building, room, or vehicle. Doors are generally made of a material suited to the door's task. They are commonly attached by hinges, but can move by other means, such as slides or counterbalancing. The door may be able to move in various ways (at angles away from the doorway/portal, by sliding on a plane parallel to the frame, by folding in angles on a parallel plane, or by spinning along an axis at the center of the frame) to allow or prevent ingress or egress. In most cases, a door's interior matches its exterior side. But in other cases (e.g., a vehicle door) the two sides are radically different. Many doors incorporate ...

Models Of Computation
In computer science, and more specifically in computability theory and computational complexity theory, a model of computation is a model which describes how an output of a mathematical function is computed given an input. A model describes how units of computations, memories, and communications are organized. The computational complexity of an algorithm can be measured given a model of computation. Using a model allows studying the performance of algorithms independently of the variations that are specific to particular implementations and specific technology. Categories Models of computation can be classified into three categories: sequential models, functional models, and concurrent models. Sequential models Sequential models include: * Finite-state machines * Post machines ( Post–Turing machines and tag machines). * Pushdown automata * Register machines ** Random-access machines * Turing machines * Decision tree model * External memory model Functional models Functio ...
