Handheld ultrasound scanners
I doubt you could produce an accurate scan of a fetus by jangling coins in your pocket, but I suppose anything's possible, with enough post-processing.

If only someone could device an algorithm to detect duplicates...

OK. Thanks. Looks like the multiple sensor thing may be more for phased arrays than camera analogy, but interesting stuff, anyway.

So like I said in my original post, " Do they simply paste together images based on matching overlap, like dendrochronology? " Thanks.

I don't know. But it's not a camera, is it? It's an ultrasound device. A camera has a whole matrix of sensors for each pixel.

So why do they move it about on the surface of my body?

Thanks, but that doesn't answer my question. How do they know where they are, relative to my insides?

Safely measure 12v boat battery voltage with AVR
Thanks. I agree about the zener, butwould have thought the internal clamp diodes would suffice with a 47k resistor. I don't need extreme accuracy, but apparently the digital video...

Safely measure 12v boat battery voltage with AVR
Thanks. The person I'm doing this job for (the voltage monitor is a mnor extra), has plenty of experience of boat stuff. He built a whole bunch of stuff for Ellen MacArthur, when...

Curve fit for sensor equation
Some years back, I found very useful for deriving equations that described certain relationships. Right now, the site seems to be inaccessible, however.
