The programming tools take care of all the hardware tasks, leaving developers free to concentrate on their applications. These applications can be re-used with different instruments and devices. Programmers can use the Tools directly from Windows applications like Excel or Access, from JavaScript code running on a web page or when programming in Visual Basic or other langauges that can integrate ActiveX controls. Checklist of Using IML Tools with JavaScript on a Web Page ========================================================== 1. Find your "CLASSID" which identifies the IML Tools. From the Windows Start menu select Run. 2. Enter regedit and press OK. You will be shown a list of registry entries. 3. Click on My Computer. 4. From the Edit menu select Find and search for imltools. 5. You should find imltools.IMLtoolsV6 in MyComputer\HKEY_CLASSES_ROOT\CLSID\ 6. Download the example HTML page from https://www.windmill.co.uk/imltools/jscript.zip and edit the CLASSID to match your own. 7. Edit the example HTML page and JavaScript code to suit your application. Note: Your browser must support ActiveX controls, such as Internet Explorer. For other browsers, like Firefox, you will need a plug-in for ActiveX controls. Further Reading =============== The IML Tools User Manual https://www.windmill.co.uk/help/imltools.pdf Instrumentation with Excel, JavaScript or Visual Basic https://www.windmill.co.uk/tools.html ________________________________________________________ ________________________________________________________ Excel Corner: See Quick Calculation Results ________________________________________________________ Want a quick calculation on a column of numbers but don't need to store the result? Use Excel's status bar. You can see the minimum, maximum, average and sum values. You can also see a count of values, and a count of numerical values. To change the type of calculation, right-click the status bar. In Excel 2007 you can see several results at once. In earlier versions of Excel you can only see the results of one calculation at a time. When you change your data selection in the worksheet, the calculation will be updated. A handy way to make a quick calculation without modifying the spreadsheet.

New free compendium of electrotechnical terms The standards organisation, IEC, has launched its electronic and electrical term database online. Known as Electropedia, this makes it easy to find an internationally-agreed technology term, in English, French, German or Spanish. Terms in other langauges (Arabic, Chinese, Italian, Japanese, Dutch, Polish, Portuguese, Russian and Swedish) will be added later. You can search or browse categories, and see definitions of terms.

Each of the 24 cantilevers of the fishbone sensor works like a human ear membrane to pick up individual frequencies. After receiving the individual frequencies, the sensor automatically performs FFT (Fast Fourier Transformations) for monitor display. The fishbone sensor is designed to pick up emergency sounds in loud surroundings.

The current way of making solar cells is done at high temperature and very low pressure, making it an expensive and energy- intensive process. Source: New Scientist http://www.newscientisttech.com/ Solar Cells That Work All Day Solar cells generally crank out the most power at noon, when the sun is at its highest point and can strike the cell at a 90-degree angle. Before and after noon, efficiencies drop off. But researchers at Georgia Tech Research Institute have come up with a prototype that does the opposite. Their solar cell, whose surface consists of hundreds of thousands of 100-micrometer-high towers, catches light at many angles and actually works best in the morning and afternoon.

The new standard published by the International Organization for Standardization (ISO) should be especially useful in environmental testing of products and components in high-technology industries such as computer and aerospace manufacturers.
