摘要:
A composite object group (COG) data structure embodied in a computer-readable medium for building a control system that has both a clock cycle and event processing is provided. An interface for passing information to and from the COG data structure is provided. One or more data flow objects are provided in the COG to accept input data and to produce output data on the clock cycle. The data flow object is connected to the interface and provides sampled-data processing for the control system. One or more state machine objects are provided in the COG; each includes a plurality of states and a plurality of transitions between the states that are each triggered by an event. The state machine object provides event-driven processing for the control system, whereby the COG data structure provides both sampled-data and event-driven processing for the control system.
摘要:
A development tool combines advantages of a simulation tool with an object-oriented modeling tool, including a real-time mathematical matrix library and an object model. The tool is applicable to any intelligent control system. A composite object group (COG) contains both sampled-data and event-driven capabilities. COGs merge procedural and object-oriented programming, and provide explicit, graphical integration of both types of processing and are fully hierarchical. A control system is built up of object-oriented components, including these types: atomic, interface, data flow and state transition. A finite state machine (FSM) component is built from states, transitions, events and state transition components. Data flow components provide sampled-data capabilities. FSMs provide event-drive capabilities. Each component may include methods and attributes. A COG includes any type of component including COGs, graphical interconnections between components, and is used to graphically build a model of a control system.

A development tool combines advantages of a simulation tool with an object-oriented modeling tool, including a real-time mathematical matrix library and an object model. The tool is applicable to any intelligent control system. A composite object group (COG) contains both sampled-data and event-driven capabilities. Mapping the computing resources of a computing device throughout the hierarchy of a control system is provided for modes, executable programs and threads of a processor. Within a given processor, each component of a control system may be assigned to individual execution threads within that processor simply by naming a thread.

An L-shaped shipping container for packaging chairs and other articles of furniture is provided. The container includes a bottom tray, a body portion and a cover. The body portion of the container includes side flaps which are folded laterally inwardly to impart additional strength and rigidity to certain corners of the body. The configuration of the assembled container also provides reinforcement to the top and a front shelf portion of the container. The configuration of the container further enables the cover to be held in place on the body by frictional engagement with said body. The assembled shipping container has no protruding flaps or panels that must be fastened down prior to closure, and therefore the container may be passed through automatic or semi-automatic bending machines for final closure.
