What is Device: Definition and 530 Discussions

CONFIG.SYS is the primary configuration file for the DOS and OS/2 operating systems. It is a special ASCII text file that contains user-accessible setup or configuration directives evaluated by the operating system's DOS BIOS (typically residing in IBMBIO.COM or IO.SYS) during boot. CONFIG.SYS was introduced with DOS 2.0.

    Efficient Heat Transfer Device for High Temperature Systems

    Please don't beat me up too badly. I ask this in all sincerity. A very small device adds energy to a system primarily via radiation. Temperature differential is high—at least 1,500°F. The system itself is rather massive—tons. Intermediate heat transfer is via forced convection of a...

    Designing a Non-Mechanical Timing Device: Ideas Needed!

    I need to design and create some sort of device to measure an interval of time between 10 and 40 seconds. I can't use any electrical or mechanical things. I had ideas of puting water in a funnel and letting it fill up a cup in which I've measured how much water equals a second for example. I...

    Can Lightning Be Utilized to Create an Anti-Gravitational Device?

    i was wondering if using the principle of lightning and how it works, could be harnessed to make a anti-gravitational device using strong electromagnets and a enormous amount of power. but in theory could it work?

    Inventor claims to have built device that can see through walls.

    Perhaps you’ve heard of Troy Hurtubise. He’s the guy who built all those bear proof suits a while back in the hopes that he could one day survive a grizzly bear attack. He was also featured on the Canadian Discovery Channel a couple of times since then for his invention of a cheap and effect...

    Negative energy and opposite self-induction device

    Hello. Take a look to this page: www.geocities.com/nayado/ You all know that in a normal induction process, a back-emf is generated that tends to oppose current flow. All our motors, generators and devices work like this: You introduce a flow or movement, and the device operation will...

    Constructing a small EMP device?

    Well, it's more or less for robot constructon thing. Does anyone know if it's possible to construct a small EMP device that'll only have a couple meters worth of area effect? If there is, any hint on how to do it, or how much it would cost? Everything that I've found so far includes some type of...

    Egg Drop Device Acceleration Question

    In science we had to build a device which, when dropped 3 stories onto cement, should not allow an egg inside inside of it to crack. One of the follow up questions says : Why should your device accelerate slightly slower than the gravitational acceleration of 9.8 m/s/s " - I can't understand why...

    What is a Perpetual Motion Device and How Can I Make One?

    I make a perpetual motion device. It is a kind of overbalanced wheel. :wink: It is very simple mechanism. I am trying to make its prototype (or toy model). It is on paper now. :confused: I am trying this month only. After that I will cut my drawing in ten (10) parts.I ll release all drawings...

    Give use your best perpetual motion device ideas

    This thought was inspired by reading the other thread "perpetuum mobile" where ZapperZ posted an interesting (but of course flawed) perpetual motion device. It was fun to analyze and to figure out why it didn't work and I was wondering if anybody else had neat ideas that seem to very...

    A device which will let us see all

    first thing, do you think such a device can be technologically feasible? do you think we need it? i think if we can build such a device why not?! i think the advantages of it are more than the disadvantages.

    A laser is a device that uses light flashes to excite the atoms

    A laser is a device that uses light flashes to excite the atoms so you get electrons with energy levels about 2 or 3 levels above the ground state. They emit photons, which vibrate at a particular frequency, they get reflected off the half silvered mirror, to excite electrons and make them emit...
