      From their web page: "The FCC sets aside frequencies between 420 MHz and 450 MHz for Amateur use, thus we are complying with the standard by transmitting our signal at 433MHz." IAHRO (I'm a ham radio operator - for 46 years.) It is fine to transmit on 433 MHz IF they have an FCC license and the transmitter identifies it's call sign at the proper interval. Otherwise, it's not legal.

      Amateur radio does not mean unlicensed. Getting a license is very easy. Check with your local ham radio club for details or visit http://www.arrl.org/

        Though I'm no regulatory expert in the matter, I've seen numerous unlicensed devices operating at 433 MHz. As long as they adhere to Part 15 [gpo.gov] of the FCC rules, they're likely okay.

          There is in fact a section of part 15 (don't remember it now, sorry) that permits very, very low power transmission on VHF and UHF frequencies. Garage Door openers and the like. 433MHz has become popular for weather stations and similar devices.

        First of all, I too am a ham and hold a "new" extra ticket in case anyone cares.

        Many hams seem to not understand Part 15 [arrl.org] which allows unlicensed operation in almost ANY part of the spectrum. In particular, there are only a very few specific frequency ranges where "intentional radiation" governed by part 15 is not allowed. This simply means that you are building a device which is intended to be a transmitter as opposed to being one accidentally. Computers, for example, transmit accidentally and are therefore goverened by part 15.

        There are also specific ranges, such as those used by wireless phones and 802.11b, where there are bands set aside with specific restrictions on power, antenna size, etc.

        Even if there is no such range in the 430mhz band one can still use that band as long as you restrict the field strength of your transmitter to 200 microvolts/meter measured at a distance of three meters from the antenna. From a practical perspective this is a transmitter that if placed inside a small building probably would not radiate significantly beyond the walls of the building.

        Part 15 transmission should not intefere with licensed transmissions and hams are very protective of their hard won spectrum space. Thus hams seem to frequenly speak out against unlicensed usage even when it might not be warrented as they have experienced significant inteference and spectrum space loss over the years. While it doesn't necessarily sound like this is inappropriate use of 430mhz, whenever you are operating close to ham bands it would behove you to be sure you are operating within the bounds of the law. Not becuase "it's the law", but because hams are very protective and self-policing and you are more likely to get a complaint than if you are in one of the specific part-15 ranges.

        On the other hand, the comments on here that suggest it's no big deal to cause interference seem to reflect the general ignorance of slashdot in regards to radio/electronics. Before you start talking about "leaky transmitters" sic, and rules you have never read, perhaps you should go read a book or two on the subject.

    It's interesting and all, but isn't it overkill? I mean they are using an accelerometer! Couldn't a simple CDS photocell detect when the thing is empty based on the ammount of light filtering through what's left of the beer? Seems like it would be simple to calibrate. Just take one, fill it up with the maximim ammount of beer before a refill is called for (since you may have a tiny bit left when it's still "empty"). Set it on a table and press a button, it's callibrated. Even a simple mercury switch could probably be set up to do this reliably without needing an accelerometer. And if you were willing to permantly modify the container, you could do more like a small float, tiny bits of metal on the side so you could use conductivity to figure it out, a pressure sensor (beer weighs more than air), etc.

    I'm not denying that their idea works, it just seems there is probably an easier (or at least cheaper) way.

    I recognize the fact that I'm in college and don't tend to spend a lot of money on food so I over tip (sometimes the amount of the meal) when the (usually) waitress does a good job. At places like Chili's or Ruby Tuesday's a plate usually doesn't go much over $7. 15% is barely a $1.00. She does pretty much the same amount of work regardless of how expensive my plate is so I usually don't tip less than $5. I've also worked food service so I know what the job is like.

    This is nice for personal parties when there's a lot going on but it's not encouraging to patrons who busted their ass all day and now get to watch the waitresses or whoever sit in the back getting paid to watch the beer indicator.

    When I worked as a host for birthday parties at a kid's pizza place, the pitchers where the excuse to keep myself visible to the parents and active in the party in order to get a larger tip. You fill the pitchers before they become empty and while you're doing that you talk to the parents and see what else you can do for them.

    In the food business that's the way it works. The more involved with the customers you are, the better the tip. So although a nice novelty, it could have a negative impact on the tip for those who use it to try to make their job "easier."

    To be really useful, the notifiaction ought to take into account the temp of the beer (if it's room temp, it's probably not being actively drunk-- abandoned/empty/etc), weird angles on the bar table, and (most importantly) time (if it's 1:45, there are going to be a whole lot of beeping pitchers, but only a few will need refilling-- and those few will have to be refilled asap).

    The time thing is probably the most important-- maybe prioritize based on previous purchases or your local ABC laws, etc.

    This is an incredibly good idea. I think every bar needs to use these. Quick response and low latency is of critical importance when you're trying to get drunk.

    Now all we need is method and apparatus, er, that is, a solenoid-operated tap controlled through a command line utility that works in most UNIX shells, so we can refill our pitchers or glasses from our keyboard. It might look something like this:

    refill -v=pint -b=guinness

    (It would be similar to the Pizza Party [beigerecords.com] utility advertised in another of /.'s stories posted tonight [slashdot.org], except it would refill beer instead of ordering pizzas. The -b option would use a flat text file to map beer names to tap numbers for maximum convenience.)

    Then, we could create a beer glass or pitcher monitoring daemon, beerd, which would invoke refill every time the pitcher empties, sending as the -b argument the name of the beer with which beerd was originally invoked.

    I can see it already: U.S. Patent #287542384328092840234, Method and Apparatus for Refilling a Beer Pitcher or Glass Through a UNIX Command Line Utility, and U.S. Patent #234823084932842843492, Method and Apparatus for Providing a GUI Frontend to the Beer Refilling Command Line Utility. (The GNOME version would be called Geer, the KDE version would be called Keer, RMS would insist that names of beer should be changed to GNU/Guinness, etc.) And, needless to say, U.S. Patent #234823084932842843493, Method and Apparatus for Automatically Invoking the Beer Refilling Command Line Utility, After Optionally Displaying a Dialog Box that Reads, "Are You Sure You Want Another Pitcher, You've Already Had Ten Beers Tonight?" With The Yes And No Buttons Moving Around So The Drunk Can't Click On Them.

    And as if this isn't enough, we'll invent Pay Per Drink, a system whereby you get a keg of Guinness and a tap installed in your home for free, and when you activate the tap, a charge will be made to your credit card through the Internet. Brings new meaning to DRM. But to make IRC conversations with your friends across the globe more interesting, you could download ebeerd, the Extended Beer Daemon, which would allow your friends to "buy you a beer" through the Internet, which would be dispensed through the tap at your house. Then, you can buy all your friends a round, from the comfort of everybody's home, with a single click. (GUI frontends for GNOME and KDE should be forthcoming for this one, as should a Jabber plug-in.)

    Hmmmmmmmm... All this talk about beer, I need to get me a drink. Lucky I have some Guinness around. :-)

    Guinness. Because friends don't let friends drink Lite Beer.

    (Astute readers might notice that a long time ago, I didn't like Guinness and made a lot of posts where I said so. In fact, for a while, my sig even said something to the effect of, "George Killian's Irish Red. Because friends don't let friends drink Guinness." So what's changed? I discovered the difference between Guinness Stout and Guinness Draught. I stopped drinking Stout, started drinking Draught, and that fixed the problem. Now I drink at least a pint every night. Oh, and by the way, Irish Red [killians.com] is really, really good!!!)

  • "The angle of the pitcher is monitored and calculated within our code at a rate much greater than an individual could ever pour a beverage out of a pitcher, thus the speed and concurrency is sufficient."

    Clearly these folks haven't ever seen a beer pitcher fly out at about 360 degrees from a drunken frat boy's hand.
  • Anyone remember this [cam.ac.uk]? I remember running XCoffee when hanging out at CL ten years ago.
  • the last few years have given us: blue teethed camera phones, wi-fi, gps, i-tunes, etc. All useless compared to this fine implementation of hi-tech that will benefit all of mankind for generations to come.
  • The best solution I've ever seen of this problem was the Rio restaurant that had a metered beer tap on every table. Not entirely unlike a gas pump.At the end of the meal you got a bill with the total amount of beer consumed at the table.

    Or so I assume. I can't really remember that part of the night very clearly.
    • Thats fuckin beautiful. Must have been a pain to install all that though, its bad enough running all the hoses from the kegs in the cooler in the basement up to the bar. Probably either a money saver (less wasted beer/every drop is payed for) or people buy more beer because its right there.
  • What if everyone finishes their pitcher at the same time, could we see the slashdot effect at the bar?

    Why is not there a simple button on each table in each restaurant of more than 5 tables: "Excuse me, waiter, I need something".

    The cheapest thing to add, it would remove the irritation of having to catch the waiter's eye, and allow the waiter to know, everyone is fine without constantly looking at all tables.

    Airplanes had this for years, but I'm only aware of one restaurant, where such a system is in use.
