Windmill News: Windmill release USB Drivers for Windows 7
________________________________________________________

Windmill are pleased to announce that their USB drivers 
are now fully compatible with 64-bit Windows 7.

USB is a popular option for data acquisition for many reasons.

1. With a USB hub you can connect many devices to one 
   socket - letting you easily expand your system should 
   requirements grow.

2. The equipment can obtain power from the USB; it doesn't 
   need to be battery powered or plugged into the wall. 
   This makes USB ideal for portable data acquisition 
   with a laptop.

3. You can plug in and unplug your equipment without 
   switching off your computer or restarting Windows.

4. The USB cable can be up to 5 m long. However, using 
   USB hubs between cables you can reach 30 m.

5. You can use USB devices alongside existing 
   data acquisition equipment.

USB data acquisition units are available from the 
Windmill on-line shop at 
https://www.windmillsoft.com/daqshop/data-acquisition.html. 
These let you:
- measure temperature, strain, pressure, resistance, 
  voltage and current
- control analogue voltage and current outputs
- switch digital outputs
- monitor digital inputs
- count events

Prices start at just £295 for hardware, drivers and 
Windmill Logging, Charting and Control software. See a 
comparison of USB units at

Excel Corner: Debugging Formulae
________________________________________________________

You've entered a complicated formula, but it is not 
working as expected.  What is the quickest way to find 
the problem?

Let's use as an example a formula to find the 
average readings per hour:
=SUMIF(Hour,"=16",Temperature)/COUNTIF(Hour,"=16")
(See Monitor 80 for details:
http://www.windmill.co.uk/monitor80.html#Excel)

Highlight the SUMIF part and press the F9 key.  Excel 
shows you the results for just this part of the formula. 
Now do the same with the COUNTIF part. A quick and easy 
way to see which is causing the problem.

4.3 million cars in Europe have a telematics device
   According to a new research report from the analyst 
   firm Berg Insight, 4.3 million passenger cars in 
   Europe will have an on-board telematics device at 
   the end of 2010. Stolen vehicle tracking is still 
   the main application, followed by automatic emergency 
   call, driver assistance and motor insurance telematics.
