Comment Re:I am amazed that there is no current limiter (Score 1) 237

Resettable polyfuses are a wonderful idea - but they would not work. They require too much area to heat up and as a result - are slow. This sort of application requires a more traditional fuse. Such a fuse would require significant board space and still require that blown devices be returned for repair. In short, unless this becomes a serious problem, I can not see such protection circuitry being added.

That is basically what a protection diode is - except they do not use zener diodes. They have one diode connected to ground and one to VCC. If the voltage drops below ground, one diode conducts clamping the voltage to ~-0.7v. If the voltage increases beyond VCC, the other diode conducts and clamps the voltage at VCC+0.7v. This is effective when dissipating a small charge that could potentially be at a high voltage - think ESD. But if you have prolonged current the diode will blow and short.

So you have a short (blown diode) but you still have a significant amount of energy to dissipate. This results in a large current that will cause the diode to physically explode or possibly blow a trace. USB data lines typically use very thin traces and can not conduct much power. If a trace goes then USB is screwed but the rest of the computer will probably function correctly. If the diode explodes your protection is gone and the high voltage will now cause all sorts of damage.

Of course they have current limited USB switches. The point is this device slowly collects charge over time then drops it onto the data lines instantly. The protection diodes found within the USB host are only designed for ESD-like voltages and currents. They can not handle a high voltage being applied for a long time. They blow then the rest of the USB chipset blows. If you are really lucky, the charge then passes through the USB chipset and blows other ICs in the host.

Many people like Trump because he appears to be honest and genuine in what he says. This always made me laugh because I view him as the exact opposite. He says what he does to appeal to those whom he is speaking to. He is the least honest of all those who ran for the Republican nomination. A complete BS artist. I am willing to bet there is never a complete wall, Mexicans are not all deported, and Obamacare is not repealed - in name possibly but not in practice.

What is really depressing is that by spewing this crap, Trump was able to get sufficient votes to be elected.

Comment Blame the news websites. (Score 4, Insightful) 624

Notice how many news sites (like CNN) now interleave fake story links with their real stories? And we wonder why the general populous is confused. If the news organizations want to regain lost trust they need to do away with such tactics. As it stands, the news sites are basically endorsing these sites.

Specifically, Moores Law states that the complexity (ie, number of transistors) for minimum component cost increases by a factor of two per year. Translating this to computer speed or process size is easier said then done. Several other factors impact the minimum component cost. For example, the number of defects per unit area of a specific process. And when it comes to the actual parts manufactured, designers could opt for more transistors or a reduced, albeit not as efficient (price/transistor), final price. Either way, Moores Law still applies.

Comment Re:Out sold? (Score 1) 209

Unfortunately every products costs the amount it costed t produce it plus the margin the producer wants to make. And that has nothing to do with what "the market" is willing to pay for it.

The margin the producer wants to make is based on the number of sales the producer wants and what "the market" is willing to pay. If sales are too low, the producer typically lowers the price. If sales are too high the producer either increases the price or increases production. Increasing production generally increases the unit cost over the short term so producers try to avoid this. But everything is based on what "the market" is willing to pay. Should production cost exceed what "the market" is willing to pay the producer ceases production and drops out of the market. So the production cost only determines if a product is produced in the first place.

A big waste of money, I agree. But this gun should be able to strike a vessel being guarded by a missile defense shield while keeping far enough away that it is not put in danger. For example, sinking a defended enemy carrier. There will also be other niche applications where this gun is a perfect solution. But one could easily argue that this does not justify the price - and I would have to agree.

Comment Resistant to bending.. (Score 2) 95

Looks like people are making this out to be more then it really is. I assume the main purpose is to allow for devices that can tolerate repeated bending - such as leaving it in you back pocket when sitting down. The described patent would eliminate the "touch disease" that was reported with the iPhone 6.

You can safely forget about that after the calls are concluded

This is the point of encryption. They never have the unencrypted data so there is nothing to forget. If they have the information at any point in time, authorities produce a warrant requiring them to remember that information. This is why the metadata is fair game - the provider (Apple in this case) requires it to operate. But the data contents (email, documents, etc.) are never decrypted by the provider and remain secure.

Hell no. We are not talking about a 100W CPU/GPU, we are talking about a touch controller IC that uses almost no power. Thermal cycling due to regular use is not an issue. I am not saying that the solder connection is not to blame, just that the cause of the problem is not thermal cycling. If one is having repeated failures then they are obviously carrying the phone in such a way that it bends. The back pocket is the worst place to carry a phone, but the front pocket can also be bad. Some people do not even realize they are doing it. But one thing is certain, if you have 9 successive failures, it's you. Better odds of winning a lottery then having 9 successive failures -- or at least it is close.

I noticed that the iPhone 7 is not any thinner then the 6+. A tiny bit thicker even. This bodes well for the durability of the 7 so it is possible Apple learned from their mistake. Not that the 6+ is defective, but it could definitely be stronger.
