Cheaper more reliable hall effect sensors... heck ya. Pretty interesting too, I wish they would have gone into more detail but with them starting up a company to manufacture products using that technology I suppose they don't want competition before they open their doors. :)

If the paint acts as the target substance for a nuclear magnetic resonance detector,
the electric current output they speak of is detected by measuring changes in exciting
current's Q. How complex is the control chip?


" hopes to combine his technology with similar developing magnetometer technology known as an organic magnetoresistant sensor,"

How do you read this? The circuit element changes resistance with B ?

So let me see if I am reading this correctly, they used the $21.5 million taxpayer funded facility to research this, and now they want to file for a private patent?

That sounds about right to me...

The taxpayers could apply for the patent, but alas, the government cant. It isn't a person.
