Question of the Weekly Q406
December 26, 2006 QUESTION: Can a vision system reject cartons with incorrect bar codes? Khalid Jamal Khayyat, Pharmaceutical Solutions Industry Ltd., Jeddah, Saudi Arabia, wants to know, 'Is there a vision inspection system available that can read barcodes on carton labels as they move down a production packaging line, and can reject cartons that have incorrect bar codes?' This is a classic control application using machine vision, and there have been a number of systems built to do it. With a popular application like this, your best bet is to look for a pre-packaged application from a major vision-equipment vendor, such as Cognex or Systech International. To pick the right system, however, you'll need to supply a few details about your application. First, how repeatable is the position of the barcode and label? At issue is where will each barcode appear in the camera's field of view. In some situations, the barcode is sure to appear in exactly the same spot in the field every time.

Understanding control valve bench set
C ontrol valves are frequently reused, disassembled for maintenance, or 'stroke tested' before installation. A key factor to ensuring that control valves perform as expected, is understanding how operating conditions, changes in packing material, spring compression, and other influences contribute to overall control valve performance. During control valve and actuator sizing, several factors must be considered to ensure the actuator can move and maintain the valve plug in place while operating at process conditions. Factors influencing control valve performance under operating conditions include: Diaphragm loading pressure , which is frequently 3-15 psi, but may be significantly higher, especially when a positioner is being used. Diaphragm effective area is defined by the size of the actuator. Most manufacturers offer a variety of actuator sizes. Valve plug stroke and travel is determined by sizing the valve body to meet flow requirements. Secondary forces acting on the valve plug in order of importance include static unbalance, dynamic unbalance, packing friction, stem size, and diaphragm hysteresis. Spring characteristics are the most active of all influences and should be determined after all other factors have been considered. A control valve and actuator assembly is tested on a bench, not under actual operating conditions.

Open, Modular Architecture Controls at GM Powertrain — Definition of OMAC Concept in GMPTG
Definition of OMAC Terms Illustration of the OMAC Concept Various Levels of Openness Other Factors Definition of OMAC Terms Definitions of key terms associated with the open, modular control systems described in the OMAC White paper are restated in the following table: Terms Definitions open allowing the integration of off-the-shelf hardware and software components into a 'de facto' standard environment modular permitting 'plug and play' of components scaleable enabling easy and efficient reconfiguration to meet specific application needs economical achieving low life cycle cost maintainable supporting robust plant floor operation (maximum uptime), expeditious repair (minimal downtime), and easy maintenance These definitions also accurately reflect the OMAC concept at GMPTG. Two important elements in the definition of 'open' are (1) the requirement of a 'de facto' standard environment, and (2) the availability of commercial control hardware and software components. GMPTG is not going to wait for an international standard for an open architecture control to be defined before it will start implementing OMAC systems.
