Comment Re:So, not really stereo (Score 1) 82

Not really anything regarding stereo, but how to digitally recreate a 3D space and provide the resultant acoustic signature to stereo headphones? So, you could digitally model Carnegie Hall, or a warehouse, or a coffee shop, and if you know the locations of your point sources of audio you can then create what the room would sound like based on a given listener location and orientation? It sounds (a bit like) raytracing for audio, with the format allowing a standardized way to define the space.

Yes? No? For once, I think we actually need an *article* to go with this abstract, or at least a Bennet Haselton-style rant* as the summary.

*except factual, useful, and correct.

Kind of... You know how, even though you only have two ears, you can still determine whether a sound is coming from in front of you, behind you, above you, below you, etc.? You don't need 5 ears or 7 ears or whatever surround-sound standard you think of, and yet you still get a great 3D image. It has to do with some complicated math our brains are instinctively doing, measuring the interaural phase differences of low frequency signals received at each ear, and interaural timing and amplitude differences of high frequency signals. A signal from your right that gets to your right ear has to travel an additional foot and a half or so to get to your left ear, and that results in a phase difference for a signal with a long wavelength (say, below around 800 Hz) or a time and amplitude difference for signals with shorter wavelengths.
Additionally, your ears are not symmetrical, but have a small reflector at the front, a curved reflector along the top and back, etc., and these reflectors have specific reflective and absorptive bandwidths, so signals coming from different directions (above you, below you, etc.) are filtered in slightly different ways.

All of these features make up the head-related transfer function (HRTF) that acts as a filter on a signal based on its frequency and 3-dimensional position around your head.

As an aside, binaural recordings are typically done with things that look like headphones, but are actually microphones placed very close to the engineer's ears, so that the audio they pick up is affected by the HRTF. When you play the recording back over headphones, you get incredible 3D audio. And Neumann makes the KU 100 head-on-a-stick binaural microphone that actually has rubbery ears and microphones placed where eardrums would be.

This standard defines ways to store and process the HRTF so that recordings can be decoded by binaural processors for playback in earbuds or headphones. Importantly, it allows a recording to be stored in a format capable of multiple ways of decoding, so that you can have one track that you can play in surround sound from your speakers, or load up on your phone and play through ear buds, and still get a great 3D environment (binaural recordings don't work effectively through speakers, and surround sound collapses down to stereo through ear buds; this allows one file to play on both).

> but also because I can get much better sound quality out of headphones for a fraction of the price of comparable speakers.

Doubtful. The distance between your ears and your headphones are far from long enough to experience lower frequencies.

That makes no sense, both from a physics standpoint and a common sense standpoint. For the former, sound is varying air pressure over time. Distance doesn't come into it, and you don't need to run around in a space to hear low frequencies.

For the latter, the distance between ear buds and your eardrum are approximately what, half an inch? Sound travels at about 1000 ft/sec, or conversely, has a wavelength of 1 ft at 1kHz, 1 inch at 12 kHz, and a half-inch at 24kHz. If your ability to hear low frequency depended on the distance between your ear and the source, then no one wearing earbuds could hear anything below 24 kHz, right? And since most people can't hear above 20kHz, then ear buds would just be silence generators, right?

Or, if you wanted to hear the rumble of an approaching train in the distance, you wouldn't put your ear on the track because "the distance between it and your ear wouldn't be enough to hear low frequencies" and instead, you'd want to stand several feet away?

In fact, as noted above, the wavelength of 1 kHz sound wave in air is 1 ft. At 100 Hz, it's 10ft, and at 20 Hz, it's 50 ft. How many people have 50 feet between their ears and their speakers? Or even 10 feet in most living rooms?

Your post makes no sense, no matter how you think about it.

I always assumed CCV was designed to offer basic protection against incidental photographs of the card being taken, and other situations where only one side of the card has been compromised.

Not really - Amex puts its CCV on the front of the card. The real purpose is that the CCV isn't encoded in the magnetic strip, and isn't embossed, so theoretically, someone using a magnetic swiper to steal data or someone dumpster diving for those old carbon paper-imprint style records would get the numbers but not the CVV.

But of course, the person who is stealing your credit card info is most likely your waiter, and they have a minute or two with your card over at the POS to copy down the CVV manually.

Comment Solution: $5 wrench and the phone company's CEO (Score 3, Funny) 79

As per the XKCD comic, the solution is a social one, not a technical one. Spam callers spoof their numbers, which is why they're so difficult to block, but caller ID spoofing is explicitly allowed by the phone companies, who let the spammers specify a "calling from" number to be included in the caller ID data. However, the phone company knows exactly where the real call is coming from and who is making it - that's how they bill the company for the 20,000 phone calls they make every month.

And why does the phone company do this? Because the spammers pay them decent money, and most people don't realize that the phone company's involved, so they get mad at the spammers and not AT&T or Verizon.

So, the solution is to send a burly man with a wrench to the CEO's office and ask him politely to stop letting companies specify different caller ID numbers, if he would like his kneecaps to remain intact.

Comment Re:I never understood the recent patent reform (Score 1) 99

Switching from "first to invent" to "first to file" makes no sense to me. If you're working on something for several years and some asshat hacks your computer, copies all the data, then files the patent, why should they get credit for it?

If you can show that they did, they won't.

As to why it makes sense - the rest of the world uses a first to file system, only the US was different. This harmonizes patent law and makes it more predictable for businesses, which is a good thing. And finally, despite hundreds of posters on Slashdot telling you how big a change this was and how it guts patent law, the switch from first to invent to first to file affects about 20 patent applications per year, out of half a million filed - there were, on average, only 20 interference proceedings each year, which is where there's a dispute on who invented something first. They were horribly expensive (upwards of $30-50k) and time consuming, and they occurred only after you filed your application and went through full examination... so someone could be already out $25k getting an allowable patent and then be hit with another $50k trying to show they invented it before someone else. Instead, now you can just point to the filing date and save money.

Beyond that, I don't understand how some filers seem to be able to get patents in a few months while others take YEARS to even get reviewed. Something doesn't smell right here.

Not at all - there's a process called accelerated examination, which, for a substantial fee, pushes your application to the top of the queue. People in fast moving technologies like software tend to go for that, while people in slow moving technologies like pharmaceuticals tend to prefer waiting YEARS, since they're in FDA trials and can't actually sell any product. By allowing a fast track and slow track, everyone benefits.

And then there's the patent troll problem. Why has nobody put forth legislation that requires the patent holder to also be the applier of the technology?

Because that would make MIT, Cornell, Johns Hopkins, CalTech, etc. very, very sad and gut their research departments.

Comment Re:Necissary, not sufficient. (Score 1) 99

The problem with the current system is that the PTO has taken the approach of only rejecting patents if they can find documented evidence that someone has done the exact same thing before. If there is a single independent claim for which they can't find exact prior art in a timely manner, then they approve the patent, regardless of how similar it is to other prior art. They deliberately ignore the obviousness of the patent because they don't want to have to defend subjective decisions against appeal.

The recent Supreme Court rulings have forcefully asserted that this is not acceptable. The law clearly states that obviousness is one of the criteria for patentability and therefore the USPTO and courts must take that into consideration when deciding patentability.

Do you have a citation for any of your claims? Because I've got a half dozen patent applications on my desk under obviousness rejections, and I'd love to be able to push them aside because the PTO didn't actually issue them.

You're not even a little bit fearful that "patent reform" isn't doublespeak for bringing patents more inline with copyrights or some such nonsense?

I'm not. Patent term has only ever been extended once, to comply with an international treaty (the Paris Convention on Intellectual Property), and even then, it was a negligible change (20 years from filing, given an average 3 year delay from filing to issuance vs. 17 years from issuance). Compare that to copyright getting extended every time someone blinks.

There's a simple reason for this. The people pushing for longer copyright terms are the publishers who want to commercially exploit their property for as long as possible, and they've got tons of money; the people pushing for shorter copyright terms are... the public. And we have no lobbying money. So, it's an easy guess as to which one wins.

But patent is different - Apple wants their patents to last a long time, but they want Microsoft's to last a short term, and vice versa. Unlike copyright, where you don't really get Sony Pictures wanting to make a Paramount screenplay without paying royalties, you actually do have tons of large companies wanting to use each other's patents. No one wants longer terms, because all of their competitors have patents they want to use. So, there's no pile of lobbying money pushing on just one side of that equation, and patent terms don't get extended.

Disclaimer: I am a patent attorney. But the above should make sense regardless of your opinion of my work.

Comment Re:Filed After Bluetooth 2.0 Was Released (Score 2) 126

This is kind of what I figured. There should be some strict limitations on this behavior. Using it for one year to hone your patent application? Fine. Using it for over a decade to make sure your patent applies to technology developed after your initial patent filing? Not good at all. Perhaps there should be a hard limit of one year between priority date and filing date.

It's already covered. When you file a continuation-in-part, the only claims that get the benefit of the earlier priority date are ones that were fully described in the initial application. Anything that wasn't described there doesn't get that priority date, and you only get the later date. So, for example, if I file a patent application that describes a peanut butter and jelly sandwich on 1/1/2000, I can later file a continuation in part application on 1/1/2010 (provided the original is still pending) that adds using cinnamon raisin toast as the bread. If that later application has a patent claim of:

1. A sandwich, comprising:
a first slice of bread;
peanut butter adjacent to the first slice of bread;
jelly adjacent to the peanut butter; and
a second slice of bread adjacent to the jelly.

That would get a priority date of 1/1/2000 for searching for prior art. If I have a second claim of:

2. The sandwich of claim 1, wherein the first slice of bread and second slice of bread are each cinnamon raisin toast.

That would only get a priority date of 1/1/2010.

So, it's even better than your suggestion - you don't even get a single day to hone your patent application. Anything new you add gets a later date.

This is absolute garbage. The most powerful claim is so generalized that it can be interpreted to cover anything the owner wishes. It's like patenting a mouse trap that consists of "a device with a mechanism such that mice are trapped".

In what way? That claim can't be interpreted to cover, for example, mouse traps. So it's not quite as generalized as you say.

Isn't copyright infringement a civil offense?

It's both. 17 USC 506 defines criminal copyright infringement:

(a) Criminal Infringement.—
(1) In general.— Any person who willfully infringes a copyright shall be punished as provided under section 2319 of title 18, if the infringement was committed—
(A) for purposes of commercial advantage or private financial gain;
(B) by the reproduction or distribution, including by electronic means, during any 180–day period, of 1 or more copies or phonorecords of 1 or more copyrighted works, which have a total retail value of more than $1,000; or
(C) by the distribution of a work being prepared for commercial distribution, by making it available on a computer network accessible to members of the public, if such person knew or should have known that the work was intended for commercial distribution.

The usual differentiation between criminal and civil infringement is 1A, for the purpose of commercial advantage of private financial gain. I think in this case, it had to do with the fact that MegaUpload made significant amounts of money through advertising associated with the pages on which they were sharing works under copyright.
