WINDMILL CHOSEN FOR NEW PEOPLE COUNTING SYSTEM

Many businesses find it useful to count people entering 
and leaving premises: shops, galleries, banks and clubs 
to name a few.  Amongst other reasons, it lets them 
evaluate their advertising campaigns, plan their 
staffing levels and see how many people are on the 
premises at any moment.  The newest people counting 
system is called Video Turnstile, and we're pleased to 
say that it is using Windmill software.

At its simplest, the system comprises an overhead CCTV 
camera connected to a Video Turnstile unit which 
detects, counts and logs people.  Windmill runs on a PC 
in a back office and lets staff view the count as it 
progresses.  Alternatively, Video Turnstile can be 
connected to a modem and data collected remotely by 
Windmill running in the Head Office.

Each Video Turnstile system can monitor up to 120 
entrances.  It is extremely accurate.  You can view the 
video  and easily validate the count: marker lines flash 
when the system detects someone crossing the 
threshold.  Each Video Turnstile unit has two counts, 
one for people going in and one for people going out.

Not all the detection and counting units need to log 
data.  An elegant design means one logging unit can be 
connected to three other non-logging units, and collect 
the count from them.  This reduces the cost of the 
system.  Occupancy and Visitor Count Meters, which can 
be mounted over doors, are available for instant views 
of the number of people currently on the premises, or 
the numbers visiting today.

The video counting systems start at
535 GB pounds.  For details see the
Video Turnstile People Counting website

EXCEL CORNER: USING EXCEL'S TEXT FUNCTIONS TO CONVERT 
LATITUDE AND LONGITUDE TO DECIMAL DEGREES
________________________________________________________

When Windmill saves data readings it does so in text 
format.  This means that you can use Excel's text 
functions on the data.  For instance, suppose you were 
using Windmill to save latitude, longitude and depth 
data with a view to creating a contour map of a lake.  
Your GPS receiver saves data as degrees, minutes and 
seconds.  However, some mapping software requires the 
information in decimal degrees.  This is quickly done 
with Excel's LEFT and MID functions.

For example, a longitude of 5330.25 North is 53 degrees, 
30.25 minutes (or 53 degrees, 30 minutes and 15 seconds). 
This converts into decimal degrees as 
Degrees + Minutes/60. In our example this would be 
53 + 30.25/60 = 53.50416667. 

To do this in Excel for a longitude contained in cell E3 
you would use
=LEFT(E3,2)+MID(E3,3,5)/60

The LEFT statement first specifies the cell reference, 
and then the number of characters to extract.
The MID statement first specifies the cell reference, 
followed by the position of the first character you want 
to extract, and then the number of characters to 
extract.
