Windmill News: 
Video Tally People Counters use Windmill Software
________________________________________________________

Biodata are pleased to announce new, low-cost, people 
counters. Called Video Tally, the new system 
uses CCTV cameras and intelligent units to count 
people. The counts are collected on a PC using 
Windmill Software. 

Video Tally is designed for businesses which want to 
monitor people coming through just one or two doorways.  
The small Video Tally unit connects to a CCTV camera 
above a doorway. It determines when people are passing 
through the doorway and increments its people count.  
Every five minutes Video Tally gives its count to the 
Windmill data collection software running on a PC.  
The count is stored in a text file which can be 
analysed in the software of your choice, Microsoft 
Excel for example.

Windmill has also written the configuration software 
for the Video Tally system.  This lets you fine tune 
the people counting settings for each doorway. For 
example, during setup you can make adjustments for:
- shadows, 
- the height of the camera above the floor, 
- whether crowds are expected, 
- people turning sharply left or right after entering, 
- whether children should be counted, 
- lighting conditions, 
- different situations such as counting people getting 
  off escalators

Other Windmill programs supplied with the new system 
include "VT Real Time" to display the live, on-going, 
count and "VT View Log" to show an historical record 
of the logged data.

Excel Corner: 
Can I Choose the Markers in a Scatter Chart?
________________________________________________________

"Can I choose the type of marker used in a scatter 
chart?" asked Charles Willson when he filled in our 
Excel Help form. Here's how...

1. In your chart double-click a data marker which you 
   wish to change.  The Format Data Series box appears.
2. Choose the Patterns tab.
3. Select the style of marker you wish.

New Vibration Powered Generator For Wireless Systems
   The periodic replacement of batteries is not feasible 
   for embedded applications and is highly unattractive 
   in wireless sensor networks containing hundreds of 
   sensor nodes.  Engineers at the University of 
   Southampton have developed an efficient kinetic 
   energy generator which generates electrical energy 
   from the vibrations and movements present within its 
   environment. The generator has been designed to power 
   wireless sensors that monitor the condition of 
   industrial plant and is intended to be installed 
   within an air compressor unit.

Earplug provides steer-by-tongue control
   A new sensor detects tongue movements inside the mouth 
   and converts them to cursor movements or wheelchair 
   commands. Engineers of Southern Illinois University 
   suspected that tongue movements could be detected 
   using ear pressure, because the way the Eustachian 
   tube connects the middle ear to the back of the 
   mouth.  In tests people wore a custom earplug 
   containing a microphone pointing into the ear.  This 
   microphone picked up subtle pressure changes inside 
   the ear caused by the tongue forcing air around. 
   Each movement created a distinctive signal that 
   could be mapped to a computer command or a 
   wheelchair control.

Printed electronics needs organic focus
   The use of organic semiconducting materials rather 
   than silicon is a key development for the 
   commercialisation of printed electronic components 
   such as sensors, displays, and functional transistors, 
   according to a report by Research and Markets.

ISA Security Compliance Institute Proposed
   An ISASecure designation is planned to identify and 
   promote security standards, conformant products and 
   systems.  Certification will provide the formal 
   recognition of a product's conformance to an 
   industry standard security specification.  The ISA 
   Security Compliance Institute is seeking 
   founding members.
