Microsoft Announces InstaLoad Battery Technology

[citation][nom]Emperus[/nom]Correct me if i am wrong but rectifiers as i understand them are basically used for ac to dc conversion.. I can understand using diode(s) on a reverse current (dc line) protection role as diodes block dc.. But this very nature would make them unsuitable to be used in forward dc current paths.. And batteries do produce dc current..[/citation]

"A diode bridge is an arrangement of four diodes in a bridge configuration that provides the same polarity of output for either polarity of input."

http://en.wikipedia.org/wiki/Diode_bridge

The problem with using a brige for each battery cell would be, as others have pointed out, that the current from each battery must pass through two diodes, with the associated voltage drop. However, this could be built into the design of the circuit, e.g., a nominal 3v circuit might use three batteries in series instead of two. I suspect though that Microsoft has come up with a more innovative solution.

[citation][nom]r0x0r[/nom]Business 101: Patent anything before you tell anyone about it.You may wish for it to be used for free but I can almost guarantee that if someone else sees real merit in this idea then they'll charge for it. Get a patent and give away the idea (at your discretion) so that when Apple inevitably infringes it you can make money then.[/citation]

Don't worry.
I' ll patent my elaboration, design of it.

With what I've said now, you don't have any concrete well thought out plans of it. There are still lots of roadblocks, pitfalls that need to be avoided to make a successful design out of this idea. And now I've said it, nobody else that isn't earlier can make claims upon it.

I'm sure Apple won't want to license this - oh wait, they make all their items with non-removable batteries to solicit even more money from customers when they fail...

MS clearly states it will not need to add anything expensive like diodes anyway, by guess would be they are going to do this to each battery slot. 2 contacts per side just like they say. and easy to integrate into current devices.

Green = insulator
Brownish color = Spring to keep tension on battery
Red Positive
Black = Negative
Blue = Batter

How no matter how you install it, it will work. no fancy stuff, it just works...this can scale with mutli-battery systems with ease.

Only the positive fits into the center hold and only the negative touches the flat part around said hole(or slot. a slot would be safer as it avoids a short when sticking in the battery.).

[citation][nom]tntom[/nom]You could do the same by using a bridge rectifier. I've done it many times on small circuits which could be harmed by reverse voltage. Just use 4 diodes with a low voltage drop.[/citation]

[citation][nom]drutort[/nom]ya but this doesnt do jack vs putting - to - or + to + on batteries, it does not correct the flow of current what your describing is the final polarity not hte polarity between batteries and yes like others said, i cant believe it has not been thought of and why didnt i think of it[/citation]

All of you are incorrect on your bridge knowlege, the bridge will switch the voltage of batteries correctly as long as you have one bridge per battery, however the slight voltage drop that is spoken of is .7-1.4 volts per 1.5-1.7 volt battery, therefor it doesn't work in this case

[citation][nom]Pyroflea[/nom]Nice, now I can just be lazy and not even look at the things I'm cramming batteries in to[/citation]
Yeah no more fumbling around in the dark with batteries for the vibrat- I MEAN... what?

This was already designed over 20 years ago.
it was just the extra cost that stopped this.
MicroCRAP is just p1ss1ing in the air with a stupid PR announcement.
