  1. Re:How about recovering the heat? on Silent Pump for Water-Cooled PCs · · Score: 1

    I've often wondered whether we couldn't attach a Stirling engine directly to the surface of the processor and recover some of the energy being lost as heat and turn it into electricity.

    Assuming this is what you want to do, why not skip the engine altogether and opt for a fully no-moving-parts-solution?

    The Peltier effect works both ways.

    Even with a passive heatsink on the cold side, it would generate current silently. Without using a fan (so it's still silent), optimum placement would be key, for instance with the heatsink outside the case. Mmmm.... static water pump for cooling with a thermoelectric device and heat pipes to a case-integrated heatsink for energy reclamation? Nice!

    Patent Pending, Patent Pending, Patent Pending!

    The principles of operation between the water pump and thermoelectric coolers seem similar. I wonder if the water pump disc can generate electrical current by forcing water through it?

    Also I noticed that MS is including driver updates in the critical updates as well (nVidia driver).

    This is just plain false. I've been using the auto-update feature and it has never downloaded an nVidia driver. I would notice when my computer reboots and the resolution is set to default 800x600. For more proof, when I go to the windows update site it lists their nVidia driver as an available download. I agree that the ones MS provides are crap and I update them myself from nVidia.

  4. Re:Not such a bad idea on Microsoft wants Automatic Update for Windows · · Score: 5, Insightful

    By default, automatic update is enabled for Windows. Anyone technically savvy immediately turns it off five seconds after installation is complete.

    Sounds like you're unreasonably paranoid. I've been using Windows 2000 for three years and whenever I need to reinstall (usually due to hard disk crashes or building a new machine. NEVER because the OS or Microsoft did something stupid) the first thing I do is go get all the updates. Nobody who is "technically savvy" wants to run a version of their OS that is three years old. Why? For reasons of security, stability, and compatibility with new software. Why not have the OS go find them for me?

    Stop speaking for me. I consider myself technically savvy due to my degrees in Electrical Engineering and Computer Science as well as my hobby of building PCs for my friends. At first, when a service pack added the auto-update feature to W2K, I had it set to let me verify updates, but then I noticed something: I kept hearing about worms and vulnerabilities in Windows on Slashdot and from my friends a day or two after I saw my PC automatically find the fix from MS. It certainly beats going to windows update myself after the fact. I let auto-update have free reign after that discovery.

    The fact is that most people who use Windows do not understand that they need to update their OS in order to keep their computer running. What's the first thing you do if you try installing a piece of software and it doesn't work? Roll back to a earlier backup? I doubt it. If your hardware seems to be working you go and get all the current driver and OS updates because developers usually release their software built on platforms with recent OS and driver versions.

    Obviously I think automatic updating could be a good thing, but there could be some problems. Nobody with a modem connection wants their OS to automatically dial in and start downloading 15MB patches. You also may not want your server to start downloading patches at peak traffic hours. I hope that MS leaves the option for user input for these reasons. It also only currently downloads critical updates. Their decisions about what is critical have been reasonable so far.

    One good thing that you might not see coming from the auto-update is that now you don't need Internet Explorer to use the windows update site.

  5. Re:DOes it work ? on Honda Crash Detection System · · Score: 1

    Car radars are not like aircraft radars. The latter only has to see something ('anything') in the middle of a big mass of air. Nothing else around.

    How can you "write radar software" and still write that? I work for a company that makes most U.S. mililtary radar systems and many civilian ones (boats, weather services, etc.). I'm not sure what part of the world you live in, but all the sky I've ever seen has stuff in it besides air. Ever hear of birds, rain, clouds, mountains, waves, trees or tall buildings? Any radar needs to take at least some of these into account when operating.

    I understand that you are trying to make the point that a radar system in a car will have to sort clutter in a different, and possibly more difficult, manner, but nobody should be told that "normal" radars don't have to deal with similar issues. Clutter detection and handling is probably the most important feature of any radar system. Not only does it define how useful a system is, but clutter detection/handling determines what the radar is used for. A weather radar will have vastly different clutter management software than an anti-aircraft system radar. One has to look for clouds and precipitation while the other has to ignore them.

    While it may seem difficult to intelligently program a system that tracks cars on a highway, it is probably not that different than what is done in other radar applications. Our company's most widely-known radar system can pick objects of interest out of large areas of chaff or debris with high accuracy.

    A car radar would have to sort out lots of echos at various doppler: the ground is coming towards you (when it's far ahead), other cars going the same direction (slower in the right lane, faster in the left lane), cars coming the other way, parked cars, things hanging overhead (bridge, street lights. advertisement...)

    You're right, it would! My question then is: So what?

    It obviously works since Honda is selling the systems in their cars while Toyota and Mercedes have similar systems available or in the works. The 30 year old ~20Mhz computer in the radar at work can track 100 targets. I think the one in these cars can probably handle that or more.

    Just imagine driving on a mountain road and out of a right curb comes a car driving the other way. The radar sees it right in front of you, coming your way. How does it react ? I'd hate to see it break suddenly, particularly if the road is wet or snowy.

    The article says that the car breaks lightly at first and then waits for the driver to respond. If the driver does not respond in a certain time-frame then the car will break more heavily. It doesn't sound like it would slam on the breaks all of a sudden. Also, if you wouldn't be able to safely brake in this situation, how do you expect to safely turn that corner? Certainly not without using your brakes.

    I really don't have a clue how such a system can work

    That should have been the only thing that you wrote.

  9. Re:Had a sociology teacher who taught EE hands on on MIT Introductory EE Goes Hands-On · · Score: 1

    The numbers do not mean much. The way the current travels through the body is a large factor in determining the lethality of a shock. If a person is electrocuted by current that passes through vital organs (e.g. from one hand across to the other) that is much worse than if the current travels from the hand down to the ground via the leg and foot. A shock of current through the heart is the worst case.

    Here's a link that I googled up

    In my line of work, where we design military hardware, I have seen crew drills (documents that show how to deploy hardware) for high powered radio and electrical equipment that warn against the use of both hands when assembling electrically hazardous equipment. This is exactly for the reason of reducing electrical shock across the chest and heart.

    Also, AC current is much worse for the heart than a similar value of DC current (that some countries other than the U.S. use). It's one thing to have your muscles involuntarily contract once, it's another to have them contract at 60Hz. An AC shock through the heart is also more likely to cause heart fibrillation than a DC shock.

    Here's another link.

    To keep on topic, I doubt that these classes use any voltages or currents that are normally dangerous. There's always the possibility of a freak 12V, 0.5A zap being fatal or damaging, however.

    Every year would be the same. you wouldn't get the great vintages. Also how would you know that you have the best vintage possible if its always the same.

    Couldn't a vineyard owner set up microclimate zones within his crops to produce a wide range of specific flavored grapes? Then it would only be a matter of picking specific flavors from the crop either for a homogenous wine made of grapes from a single zone, or a blended wine which incorporates the flavor of multiple Flavor Zones(TM). The experimentation could lead to a better wine for each vintage instead of a semi-random distribution of great vintages.

    I can also see how this would allow smaller vineyard owners the opportunity to produce more than one or two types of wine since the management of microclimates would ensure better crop yields in smaller areas.

    It's up to the vineyard owner how (s)he wants to experiment with the microclimates in order to produce grapes/wine. The imaginitive ones will probably make good use of the technology to make excellent wines of all types.

Who doesn't want a wireless information/communication device strapped to their wrist? While they're at it, throw some biometric sensors on there for kicks!

    That's a silly and non-realistic argument. There is no way that a person needs their PDA on for 10 hours at a time even on standby if they are using it as the niche device that it is. Assuming a standby time of 10 hours the actual time span would likely be at least double that if you use your PDA once every other minute. You can't convince me that you would often not be anywhere near a recharge source for even just 10 hours. If you're going to be typing papers (which can take hours) or surfing the web and checking email constantly on your wireless connection (a high-drain pursuit), then you should have a laptop.

    You can purchase more than one mode of recharge for your PDA if you really need to, for instance a second cradle, an AC adapter, a solar recharger, a USB recharger, an automotive recharger, etc.

    There and then != all day, every day. If you are using your PDA for more than 10 hours a day without a recharge then you need to seriously re-evaluate your working habits.
