Yes, as LTE-U doesn't employ LBT (listen-before-talk). That said, the interference is likely to be of a similar magnitude as another Wi-Fi access point operating on the same channel.

Just like the Motorola Canopy systems which completely trash the channels they operate on?

Some ISPs deployed Canopy just to block WISPs which became amusing when some WISPs deployed Ubiquiti Airmax systems which blocked Canopy.

Basically no one obeys speed limits. The posted speed limits are at best suggestions, and at worst revenue generators for the local governments. And many other traffic rules are casually disobeyed. Except for the stop sign, I don't see much voluntary compliance of traffic law.

This is more indicative of your area than the general way people behave on the roads. Also calling it a revenue generator is a bit extreme. Paying a fine for something completely within your control makes this a 100% voluntary gesture.

How about paying a fine for obeying the law? Where I am, police pull people over and give tickets for laws they did not break and the magistrate judges do not care and why should they? The fines pay the cities and them.

Many cities and towns have had ZERO regard for the wiring nightmare hanging over their streets. Not to mention trees and other hazards. UPS is a bunch of damn fools if they think they can simply put drones on trucks and go for it.

What do the drivers think? I read the UPS driver forums and they already had a lot of legitimate griefs and a lot of them felt overworked and pressured, so now they have to do drones, too? This is going to go over like a lead balloon in a gravity well.

Besides which, there are drone no-fly zones all over the place. The town where I live is completely off limits as we are too close to a major airport. But that's OK because there are tons of badly groomed trees and some of the worst telecom pole wiring I have ever seen. Phone, CATV, power, fiber, and above those lines are 100ft high voltage lines with at least three tiers. Even if there wasn't a flight ban here, you'd have to be a complete moron to try to fly a drone among all these wires and the trees. Forget the kite-eating tree. It has nothing on the ones around here. They don't just eat drones, they also thrown limbs at you. Seriously. They eject limbs from time to time.

So those cities and areas will not get UPS drone service; maybe UPS will charge a premium to deliver in these areas.

Comment Re:Prior Art on Slashdot (Score 1) 41

We discussed just such a system here on Slashdot about 4 years ago... If anything, that discussion should allow other players to implement their own without fear of stepping on UPS' patent(s).

The patent office has a very limited pool of what it considers prior art and Slashdot is not on it.

I call bullshit. I've been building systems with ECC RAM since the early 2000's (because I'm a paranoid fuck) and the price was never even close to a factor 5 more expensive. Perhaps you used registered RAM.

After Intel dropped support for ECC in desktop systems and during the beginning of the DDR2 to DDR3 transition, ECC DDR3 was not available and not supported and new Intel systems which supported ECC used FB-DIMM which were way more expensive than ECC DDR2. The difference in price at the time between a new AMD system using ECC DDR2 and a comparable new Intel system using ECC FB-DIMMs was roughly $1000.

There really isn't any easy way to do this. One approach I guess would be to have all the control electronics a long way from the robot and only basic actuators and sensors on the robot itself. However, video is still control electronics...

Pneumatics and/or hydraulics can be used for controls, logic, and power. Fiber optic light pipes can be used for video and incandescent lamps can be used for illumination. Scintillation can be used in combination with fiber optics for remote radiation detection and spectroscopy. Wire, transformers, relays, and motors are all suitable.

In this case, they must be the input and output capacitors of a switching power supply.

Ceramic capacitors are only used this way in applications which can support the extra cost because large ceramic capacitors are very expensive. There advantages are very low ESR and ESL, high ripple current rating, and long life. Unfortunately their large physical size combined with brittle construction creates extra reliability issues and special mounting considerations are required. I am surprised that an aerospace manufacturer would have a problem with them though.

I suppose liquid cooling - flowing right over the die - is the ultimate solution for heat dissipation.

At least with water, power densities 10 years ago already exceeded the point where film boiling is a problem so a heat spreader has to be used. We are already limited by copper heat spreaders leaving either higher thermal conductivity materials or improved heat pipes.

Comment Re:Against TOS (Score 1) 652

Because it's against the TOS, it's against the Computer Fraud and Abuse Act.

18 U.S. Code 103018 U.S. Code 1030(f): This section does not prohibit any lawfully authorized investigative, protective, or intelligence activity of a law enforcement agency of the United States, a State, or a political subdivision of a State, or of an intelligence agency of the United States.

That does not save the person giving up their password and they were the ones who agreed to the terms of service.
