You had the secondary HT in crossband repeat mode, right? That makes the HT a repeater. Was it 2m in, 70cm out, or vice versa? If it was 2m in/70cm out, it had to have been running in automatic control mode (you can't have a control link for a repeater on the 2m band). As with any repeater, you gotta ID, have the 3 minute timer, etc. How did you do all that?
How did you do the time/date/alt/pos overlay on the pics? Was it done on the balloon, or later, on the ground?
On a completely different subject but related topic, American-made ammunition uses Boxer primers (developed by an Englishman), and British-made ammo uses Berdan primers (developed by an American). Go figure!
For the curious: Boxer primers have a built-in anvil for the percussive mixture to get squished against, whereas Berdan primers rely on bumps made into the cartridge itself for the anvil. Boxer-primed ammo is generally much, much easier to reload than Berdan-primed.
As another reader mentioned, most RFID tags use unique ID's per tag, not per item, so they really would have to have an inventory mapping each tag's ID to an item.
Your points are valid, however I can see a way to use these that might actually help protect the innocent shopper. If they set up a scanner on the IN door, they can record what you had on you coming in and know not to alert (or prosecute) if these items leave thru the OUT door.
Excellent chemistry lesson! I don't think the SSME's burn anything but an H2/O2 mix, however. I'm pretty sure it's either the OMS or RCS that burn N2H4/N2O4, not the SSME's.
SSME=Space Shuttle Main Engine OMS=Orbiter Manuvering System RCS=Reaction Control System
By the way, there are several 'flavors' of hydrazine - two are monomethyl hydrazine, and unsymmetrical dimethyl hydrazine. The OMS and RCS use MMH.
...two pennies weigh ~4.996±0.014g, have a zinc core, and the face of Lincoln.
I miss the old 3.11g, 95% Cu, 5% Zn, 1982-and-earlier pennies...did you know that the new and old pennies sound different when dropped on a hard surface? The old ones 'ring out' better (clearer high harmonics). You can tell them apart without looking!
Ah! But as soon as the 48V electrical system becomes the norm, you will be able to apply some of those 'old style' tuning tricks via software. With 48V systems will come electronically actuated valves (bye-bye camshaft, timing belt, lifters, etc). I predict that valve timing will be just another set of chip params, and that good ECU's will be fiddling with the 'virtual cam' timing dynamically.
Read it here first - I also predict that Cadillac's dream of the variable cylinder count engine will be realized - with electronic valve control, inhibit fuel injection, close the intake valve, hold the exhaust valve open and voila! You have one less gas-guzzling cylinder!
Go to a party where you're hypnotized, and have the hypnotist die before bringing you out of your trance.
Don't show up for work, citing that "You don't feel like it."
Disassemble a cube wall or two.
Tell your bosses that you really don't work all that hard.
Figure out a way to collect all those fractional pennies "laying around."
Avoid being sent to pound-you-in-the-*ss Federal Prison
Steal your nerdy co-workers red Swingline Stapler.

Seriously, good luck! A few good things can happen: you're kept and enjoy your job. you're laid off and find a better job. You hate the new company and find a better job.
Too many people think cloning cells for the fight against disease is the same thing as creating Frankenstein's monster. Too many people think evolution is the idea that people are descended from apes. And too many people think that genetic modification of plants is a dangerous new idea, instead of something that's been going on for ten thousand years.

That's funny - my Make Your Own Bubblegum Kit (Which is a chemistry set all its own) says that bubble gum manufacturers use limonene and rubber for the bubblegum base.
I seriously doubt that anyone addicted to heroin would be reliable enough and in any shape to hold down a steady job, even at McDonalds. Drug addiction makes for very habit-expensive, non-productive citizens that rely on the generosity (or the theft) of others for survival. That's not something I want to encourage or promote.
PS - you could even have it change their password and read them the new (random) one for added security. If your system supports it, it could even make the new password expire on first use, so they'd have to change it. Alternatively, have it refuse to change the random password for 30 days, so they'd have to use the ugly random PW instead of qwerty1.
Set up a web portal that the users use to request their password. Have it send their password to a "dectalk" (voice synth + phone dialer) that dials their voicemail account and speaks the letters of their password. This provides some security, since they still need their voicemail PW. It will also alert a person if someone tried to get their password - an unexpected PW message will appear on their phonemail.
You can get by with only one dialer 'cause you can just batch up the requests and do them sequentially. I'm sure there are a jillion ways to get the telephony/voice synth part working. There's Bayonne, etc. Since you're only talking about letters, numbers, and punctuation, you could just have someone read the letters into WAV/MP3 files and stream them into a voicemodem. Just a thought!
Unfortunately this will only encourage people to write their password down and tape it to the bottom of their keyboard so they don't have to be humiliated by their boss.
You gotta get people to buy into the idea of security. If they don't, they'll only try to get around your security measures every chance they get.
continuously for the past 50 years, it would've performed 4.734e14 instructions. Your newfangled 3.3GHz processor performs that many instructions in 39.85 HOURS.
IMHO, it's not the chronological age of the 'child' that matters, but his/her motivation. Criminals who choose to commit violent crimes are also willfully taking the change to get killed. I have negative sympathy for them. The tradegy is that anyone dies accidentally, not that some choose to pursue lives that lead to their death.
I heard he wanted to look like Dianna Ross. He darn near suceeded. He at least looks just like his sister. He now wants to look like Elizabeth Taylor. This could be really interesting.
As has been mentioned in other replies, you have several choices for heat transfer. Conduction, convection, and radiation.
Conduction is heat transfer thru direct contact. You touch the stove, it burns your skin.
Convection is the transfer of heat via a moving medium. Air at the earth's surface is warmed by the sun's radiation, causing the air to rise. The heat is then transferred to the surrounding cold air, which causes the previously warm air to sink back down.
Radiation if the transfer of heat via electromagnetic radiation. All objects above absolute zero emit some form of EM radiation in proportion to the fourth power of their absolute temperature. Also involved is a coefficient that depends on how close a radiator is to an ideal 'black body' - ie a perfect radiator. See Stefan-Boltzmann equation Inet = e*s*A(T^4 - T0^4) where Inet is the net power radiated in Watts, e is the emissivity coefficient, s is Stefan's constant = 5.6703 x 10-8 W/m^2 K^4, A is the area, and T is the absolute temp and T0 is the ambient temp. (To get the total radiation emitted, set T0 = 0). The peak wavelength of the radiation is given by Wein's displacement law, lambda = 2.898 mm * K / T, where the 2.898 mm * K is a universal constant and T is the absolute temp of the object.
For example, a person has about 1.4m^2 of skin at 33C = 306K. If you assume they're a perfect radiator, in a room at 20C the person is emitting 111W of power, net. The emission peak wavelength is approx 9.5 um, which is in the part of the EM spectrum called "infrared".
