I really like seeing applications for image fusion like this. I think we'll see more of them in the future given how cheap HD cameras and FPGA are becoming. There's no reason why I couldn't take an array of cameras with different filters and fuse the outputs together into a single image. It's better than the Preditor-Alien vision (no cycling required)!

Take these guys for instance. They're fusing thermal and visible cameras outputs together in realtime.

How long do you think it will be before all of done on a single sensor die?

What if you got your car a rather unique paint job that featured random strings of numbers and letters at different orientations. I wonder how well the tracking system would work, or bet yet, change the paint scheme every so often.

A new study has shown that saws are so common place they could be used by lumberjacks in case of emergancy situations. The report suggest putting lumberjack accessable doors on all tool sheds.

So why isn't your audio technition using a 22kHz lowpass filter before shoving his data into the 44kHz DAC?

Put enough poles in the filter and the 33kHz noise will be attenuated to hell even before it has the chance to be turned into a 11kHz distortion.

Oh..... You mean the high def TV antenna.....

I do have to say the WISP project sounds neat. They're essentially RFID powered sensors.

Scratch that. I screwed up the units.
It comes out 104400 Joules or 29 Watt Hours.

(29,000 terawatt hours = total power used in 2005 by US) / (1 femtosecond) = 1.04400 × 10^35 watts (US useage per femtosecond)

If this much juice is used to make the filiment, how is this more efficient?
