REQ: info about pulsation meter gadget of mcdonalds

[flasher]

Hi

Recently I saw in the news that some
while ago Mcdonalds had a campaign
with pulsation meters. I think it
was in the USA only. You had to put
your finger on a little device and you
would know the beatcount of your heart.

Is there anyone here who knows more
about that device and where I could
find information about the device?
Is there a site of the firm that made
them for mcdonalds and can I contact
that firm?

Thanks in advance

Don't know anything about Mcdonalds but I would try fitness machine makers.
Most treadmills, eliptical machines and others have them built in and plenty
have them as additional peices that you can buy.

It's just a laser that senses when blood in the end of your finger is
thicker or moving (heart beat), and count's the number of pulses per
second with a simple IC
