REQ: info about electrocardiograph gadget of mcdonalds

[flasher]

Hi

Recently I saw in the news that some
while ago Mcdonalds had a campaign
with electrocardiographs. 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
