The triangulation is the easy part. The hard part is figuring out what exactly is a gunshot and what is firecrackers, backfires, kids popping plastic bags, etc. Being able to accurately determine this is not trivial, and thus is costly.
Of course, as something sold to the government, there's always going to be excessive markup, because they know they can get away with it.
I for one welcome our robotic overlords... I mean, helpers!
Last month I got to play with one of the Da Vinci units at a car show (why it was there is anyone's guess). I am amazed at how intuitive it was to use- even though I was just putting tiny rubber bands on small rubbery cone-thingies, the 3D display and 1:1 motion mapping really made it feel like an extension of my body. Even though the unit doesn't use force feedback, it almost seemed like it did (just my brain, I guess). The most amazing part? My 7-year-old niece had absolutely no problem using it, and now she wants to become a doctor.
Cool stuff.
* (10^-12 Diopter)^-1
No, the unit of 1 Diopter is equivalent to 1/meter, thus 1^-12 Diopter^-1 would be equivalent.
Even if Diopter was a proper measure of length (and it isn't), it would actually be 1/(10^-12 Diopter) as Diopter is the reciprocal of a focal length to measure optical power. Still, it's an interesting way of putting it.
How so?
Last I checked, a pair of old RCA cables can move two analog channels of audio. HDMI will carry up to 8 channels of up to 192kHz/24-bit audio.
Though it's rather a niche segment, many people watch a sporting event and tune into the radio broadcast coverage of the game to listen to the radio announcers. The team's own radio announcers are oftentimes much better at knowing what the hell's going on than the ones on TV.
Core i7 940 -> $564.99 + about $250 for mobo = $800+
Phenom II 940 -> $224 + about $150 for mobo = about $375
Core i7 needs DDR3, Phenom II 940 runs DD2 (note that the 940 is an AM2+ part, not AM3 so it doesn't support DDR3). DDR3 is somewhere around 50% more expensive than DDR2 (though falling).
For me, the fact that the i7 is only about 10-20% faster than the Phenom for more than twice the cost, it's simply not worth considering for me. Then again, I do most of my gaming on consoles.
