The "cover" or "skin" of the suit is also functional. As a systems engineer (for space-based sensors and cameras) I can think of a few requirements that need to be addressed right off the bat:
- Visible Contrast, so that the wearer can be detected/identified by humans, from a distance - EM Reflectivity, so that the wearer can be detected/identified by active scan sensors (lidar/radar/whatever) - Customization options, so that wearers can be distinguished from one another - Glare reduction, so that the wearer's visibility isn't compromised under direct sunlight - Thermal conductivity and albedo requirements, matched to the performance of the suit's internal thermal regulation - Micrometeorite protection (probably addressed by deeper layers, but also a factor here)
And that's just from 2 minutes of brainstorming...
Of course, since this suit will never actually be used in space, the systems engineering process above can be abandoned in favor of public relations, which NASA spends a small but significant chunk of its budget on...
The LAPD would only need to state that the images were captured with the intent of validating registration tags.
But they're demonstrably not doing this.
They're buying ALPR systems that are specifically advertised with the capabilities to create and analyze databases of license plate numbers, places, times, etc. in order to track peoples' movements.
LOL, clearly either a digital logic or RF engineer.
Tell ya what, if you're that confident, then take an aluminum crochet needle in each hand and jam them each in the +/– terminals of a 12 volt DC power supply, then in the line/neutral sockets of a variac output tuned down to 12V, and tell us again that 60 Hz is 'pretty much DC anyway.'
(Spoiler: one will be fatal and the other not.)
And then see if you can figure out why Westinghouse engineers chose the frequency at which electrical impulses best travel along human nerves as the standard power transmission frequency...
At least he was engaged in the act of driving, which includes both navigation and piloting.
I see way too many drivers doing something other than driving while driving, beyond just texting or chatting on their phones. I've seen people applying makeup, shaving, eating with two hands, and even reading a book.
Even with a handsfree device, holding a conversation is a distraction from driving.
I'd be willing to bet they didn't do it right. It needs to be strobed at a high rate. But it will affect the vehicle cameras as much as others, unless they have good IR filters.
Strobed high intensity NIR is the right track. Sync the vehicle camera shutters with the strobe dead time. Use a shuttered camera so the IR doesn't leave lingering effects on the focal plane. Heck, you can even use the NIR for camera illumination and use very fast shutter speeds.
I'd be willing to bet they explored this and found that either a) the necessary intensity of the NIR was beyond safe limits, or 2) the cameras necessary to work in this scheme would be prohibitively expensive. Or both.
My solution: confiscate the passengers' cameras and enforce the no photos policy strictly.
Agreed. They are rare animals but they do exist. I had the benefit of working 15 years for a medium sized company with a culture of training and promoting the best engineers into management. Not all of them wanted or accepted promotions beyond department manager, but the VPs of Engineering, QA. Operations and Program Managment, and the General Manager all started their careers as engineers or scientists. The company paid for advanced degrees in Engineering and Management for anyone who wanted them (and kept good grades). Those who showed talent were promoted into management AND still got to hunt elephants.
But I didn't recognize how unusual that culture was until after leaving that company. My current employer is a small company micromanaged by two brilliant engineers who are horrible, horrible managers.
Riiiight. Obama started this. Never happened until after Jan 21 2009.
Ooh! I've got another kneeslapper for ya: The POTUS has the power to stop the NSA if he/she wanted to. They're not a rogue organization with a nearly unlimited black budget and the momentum of a 20 ton road compactor or anything...
This is why, when the 15" MBP-Retina was announced in 2012, as I was preparing to replace my late 2006 15" MBP, I immediately went to Apple's online store and bought a refurb late 2011 17" MPB. Although the battery isn't "user replaceable" the older MBP is still at least serviceable by a tech skilled user. The new ones aren't. And for that reason it may very well be the last Apple laptop I purchase. Regrettably.
Jobs is no longer CEO (again) and Apple is losing its edge (again).

Deslide is your friend. The bookmarklet works great.
Deslided version of TFA (spoiler: you're not missing much).
50/60 Hz is pretty much DC anyway

I got my chemical education in college.
I still see the trails sometimes...
Not contradictory at all.
You're conflating two layers of protocol: The encoding layer and the modulation scheme.
You meant that as a joke, but I've seen that happen...
That's a Ten-404, good buddy.
HAM sounds like the way to go, along with a Kickstarter campaign to raise any necessary funds for custom equipment.
60% of the time you'll get out of it every time.
How frequently will you get out of it the other 40% of the time?

Alternately, make them ride in the dark. Naked.
I tend to agree. The whole issue with the suits sounds more like superstition than anything else.

There is no Five... Three! I mean three!
The "awesomeness" of the commentariat departed a long time ago. What was once "awesome" is now merely "occasionally insightful or informative."
But yes, the signal to noise ratio is plummeting even further with all of the Beta whining.
The whole system is corrupt from the bottom up.
... which makes the whole concept of a "Taint Review Team" hilarious in more than one sense: one ironic and one... well, just unfortunate.
Yes, the Bush White House was very definitely using fear of nukes to justify its decision to invade Iraq. Remember this?
LOL. That's like me telling my wife, "but sweetie, I only looked at a tiny fraction of the Terabytes of porn that I downloaded last year."

Or having the wrong tattoo. Or reading the wrong book. Or talking to (or being spoken to by) the wrong person...
It's entirely arbitrary and at the whim of the warden.
No.

Yea, but those "keys" didn't produce a satisfying "BONG!" when you pressed them to turn the PC on.
