    Heh. Reading I, Robot will tell you absolutely nothing about the movie. But it has several good stories in it.

    I'd guess it disabled it from the point of view of the bios.. IE no USB keyboard during boot-up, or booting off the USB port. But once Windows hit protected mode and loads it's internal driver for the USB controller, the ports get magically re-enabled.

    And are a problem with the new lead free processes.. especially as lead spacing decreases, and the euro lead-free requirement kicks in.

    Agere wrote a good article in Analog Zone, available at http://www.analogzone.com/grnt0216.pdf. It has a good micrograph showing the problem.

    This has been answered before.. most recently, in the Q&A on the X-prize message board. Basically, a paracute landing implies a godawfully large landing footprint... which is why the US paracute landings were all water shots.

    It was said a small landing zone should ease getting further testing waivers.

  6. The big question is costs.. on Road Marker Marks You · · Score: 3, Insightful

    Initial costs, reliability, expected lifespans. The conditions are:

    1) Outdoors in extreme temperature ranges,
    2) Very high humidity, and often corrosive atmosphere,
    3) Physically very small,
    4) Reasonably immune to physical damage (salt/sand sludge + snowplows do _nasty_ things to optical windows.)

    Power has to come from batteries at night; what is the battery life under industrial temperatures (-20 to 150F, forex.) Concrete doesn't get quite that hot, but asphault does.

    You can get away with powering LEDs with a supercap and a switcher, should have a better lifespan than a NiCD or SLA, but they're physically larger and not as robust (As well as pricey.) But that won't cut it for cameras or radios. So you have to replace the batteries every few years.

    These are not traditional road studs. 5" wide?? These are huge; the normal installation methods won't work.

    I'd like to see their business case. Almost certainly relies on questionable safety increases or revenue from being a speed trap.

    My state is running a multi-year reliability study on more traditional road studs (including those nifty blue reflectors) on various roads around the area.

  7. Re:Not sure why this is a "first" ... on New Chips Enable 2.4 GHz Sensor Networks · · Score: 1

    Just be sure your boards are solder-masked; some of the cheaper places don't do it by default. I know Olimex does do solder mask, but aside from that you're on your own. (No relationship, but you can't beat $26 for a double sided 160x100mm board in single quantities.)

    For prototyping lower-frequencies items in a similar package (LCC8) I've successfully tacked wire-wrap wire to the contacts, but it's a pain and the lead inductances will kill you at these freqs.

  8. Re:DLP: Bright, clear, and did I mention bright? on Video Projector for Home Theater? · · Score: 1

    Heh. We were at the last ALS, and got bored in the evening.. so we hooked the laptop up to the big projector and watched B5 episodes. We had attracted a dozen people by the time they kicked us out for Linus' panel.

    Zip zaps use batteries (NiCAD, IIRC), another brand (Hotwheels XV) uses a supercap (PowerStor).

  10. Re:Higher freq. & higher power = signal penetr on FCC Opens Wireless 3.6GHZ Band · · Score: 1

    Because an effective antenna array is anywhere from 4 miles to 4400 miles? (quarter-wave antenna length for those frequencies.) Shortwave installations are huge to start with, the ELF installations are AFAIK only used for military COMMs (very low BW sub comms, forex.) The military ELF antennas are not quarter wave, but still huge (56 miles total in Michigan, 28 miles in Wisconsin.)

    They are also very slow.. the 76 hz ELF system delivers about 3 characters every 10 minutes, and still only good to about 350-400 ft depth. There've been tests with even lower frequencies.

    Exactly. The ADXL202 is $10.20 for q 100-499, in the LCC package, and should go down futher for higher quantities.

    Their angular motion sensors are a bit pricier ($33/q100) and in a different package (BGA.. grr).

  16. Re:If you have a 1 or 2G ipod... on Build Your Own iPod Battery · · Score: 2, Informative

    The problem wouldn't be using the battery (discharging) but in charging. (Assuming the IPOD won't zero a pack; reversing cells is bad, m'kay.)

    You would have to disconnect one battery or the other before charging a pack. Lithium chargers are designed for specific battery combinations as they can explode if not charged properly.

  17. Re:nice theory, but -- on Arctic Ice Holds Much CO2 · · Score: 1

    Well, I haven't been shopping for hybrid (and thus took the figure from the Original Poster) but I know you can get a ~2 year old truck with low mileage for about $10k, and insurance was literally half that of a compact (~$500 vs ~$1000 / 6 months).

    Ah, okay. Just not the vehicle I usually picture for a single mother, unless in a rural environment where she would need one. More of the older 4-door, room for kids, groceries and safety seat.

    And sorry.. you hit the button on the 'wasteful polluting pickup' and got the stock response. (What kind of milage does that hybrid get hauling a 2 horse trailer? No? How about a ton of grain? A couple sheets of sheetrock and a dozen 2x4s?)

    Now the just for show 'don't come near it or you'll scratch the paint' trucks.. say whatever you want. :)

  19. Re:nice theory, but -- on Arctic Ice Holds Much CO2 · · Score: 1
    (I live an environmentally sustainable life, but it does cost a lot more and I wouldn't demand that a single mother of two do it as well -- hey, you driving that pickup! shell out $50,000 for an electric car.)

    How the #$#@ is one supposed to pull a trailer or get hay with a wimpy $50k electric car? Especially when one can get a recent used pickup for $10k and pay less than half the insurance to boot?

    If it's used exclusely as a commuting vehicle, perhaps I can see your objection. But a truck is a working vehicle, and is often used as such. SUVs used to be the same before they became fashionable.

    The FCC's talking about powerline broadband. Yeah, we're nowhere close to a commercial rollout yet, but at least the regulators are certifying that the plans won't cause massive harm to any other communications tech, so they're about to sign off on it.

    Eh? I thought it was fairly well established that all of the BPL schemes create massive radio interference in the HF bands (used for long-haul radio links, esp. emergency comms).

    Hmm.. I'd have to agree that that meaning of tariff is falling out of common usage, at least here. "Price list" "Schedule of Fees" "Royalty Schedule" all seem more common in this context.

    The other thing about royalty payments is so many firms have cross-licensing schemes nowadays; only newcomers have to pay the piper, and the price often ends up 'all the market will bear' for them (50k minimum units or such).

    241348 appears to be referring to the more specific meaning of tariff (from m-w.com)

    1a: a schedule of duties imposed by a government on imported or in some countries exported goods
    b: a duty or rate of duty imposed in such a schedule.

    While you were using it in the more generic form:

    2: a schedule of rates or charges of a business or a public utility

    Generally the money one charges on patents is referred to as 'royalties'.
