Thanks Raw!
Here's another device. If this is the same one I was shown by a Vaidya it has been around for awhile, but it is reduced in size dramatically:
http://vedapulse.com/It does Ayurveda and I believe Tibettan medicine pulse diagnosis. If it's the same one I saw, it would recommend an herb or whatever, then if you held that herb or whatever in your hand, even in a bottle, the device would show that you had corrected the imbalance. It was uncanny.
It simply measured the pulse. However being mechanical it would be unhindered (presumably) by the prejudices or poor abilities of a practitioner. But all mechanical devices have idiosyncrasies or limitations which are a result of the programmer(s) lack of knowledge and prejudices.
Naturally a well trained and observant pulse examiner will have intuitive abilities that transcend objective knowledge.
