  1. Close calls on What NASA Won't Tell You About Air Safety · · Score: 4, Interesting

    I fly a reasonable amount as a passenger (used to fly small private aircraft as well) on commercial airlines and I've seen quite a few planes that come by shockingly close. I was prepared early enough one day to get a reasonable pic out of a cheap little point and shoot here of another aircraft in reasonably close proximity, but this is by no means the closest I've seen planes fly to one another. One time flying over Columbia on this flight we followed *very* close to another large commercial airliner for quite some time. It was hard to get a picture given it was at night with a little point and shoot, but it was close enough for me to see people in windows in-between flashes of lightning. Granted this was in controlled conditions as we were flying almost in formation, but I've also seen planes flash by in close proximity flying in the opposite direction as well. Much closer than the 3-5 mile limit I understood was in place.

    Given the increasing amount of air traffic, I would not be surprised to see incidents (not comforting given upcoming travel), but the shocking thing is that the FAA (and the public) is still dealing with a completely antiquated air traffic control system that like other aspects of our national infrastructure is woefully lacking, particularly around large airports.

    I liked their use of that highly technical term: "too squiggly".

    Yeah, like uncorrelated noise of artifact are too technical details for the Patent Office.

    It sounds like they were using this method to optimize the complexity of interfaces depending on the user's level of "confusion". (E.g., when the user is in a state of panic, the graph wizard in Excel could offer three or four styles of graph, instead of 12. One of the Linux makers with Microsoft patent licensing could adapt it to look at such a user and decide "Y'know, you probably don't need the GIMP...") I doubt they've tried anything as ambitious as knowing what the user is thinking.

    LOL, no doubt. The sad thing is that there is actually quite robust science related to human machine interfaces using EEG data, but I suspect those are already patented fairly heavily and this is some sort of effort to patent what essentially amounts to nonsense.

  3. Hrmmmm.... I don't think so. on Microsoft Wants To Read Your Brain · · Score: 5, Informative

    I've spent a fair amount of time looking at this problem (as have others with certain agencies who have invested not insignificant amounts of money) and I can tell you that this is pretty much up in the night kinda speculation. Technical issues of obtaining clean EEG signals in a convenient manner aside, the origins of techniques like this to classify comes from the epilepsy literature, where folks attempt to classify interictal seizure spikes, but also from the sleep and awareness literature (both of which have been reasonably successful, yet are still lacking optimal tools). Granted, there are rather dramatic global state changes that occur with different states of consciousness, but this application focuses principally on the awake EEG. Specifically they quote the P300 signal which the FBI and CIA are using (trying to use) for lie detection, but the problem here is that the P300 is only an evoked potential that simply tells you whether or not someone recognizes an input (audio, visual, tactile etc...). So all questions or inputs into the system have to be crafted to understand that one is looking for an evoked potential with no necessary context in place to explain that evoked potential.

    So, this is not mind reading per se nor is it a means to break cognitive processing into temporal windows to determine intent in any of those potential epochs. At its very basic fundamentals this is simply a rehash of signal detection theory doing simple Fourier analysis to "classify" brain waves. But the thing here is that there is no science behind using these signals to interpret what one is thinking even with the invocation of Bayesian networks. There are a number of other more promising methods for classifying data that have been in the literature and commonly used by a number of other disciplines that I am surprised have not made it into the EEG literature yet.

    In short.... in my assessment, this is a patent proposal without much in the way of novelty or benefit to the problem at hand.

    As I said in my blog entry about it ('bout 3:00 this morning when we heard about it), I am actually surprised it took this long as it would be hard to quantify how much science has been dependent upon Mario's work or even work that comprised prior Nobel Prize awards. Certainly my science going back to my dissertation has relied on transgenic techniques pioneered by Mario Capecchi and I owe much to him, but more importantly the doors for much discovery made in bioscience over the past several decades would simply not have been possible without Mario's pioneering work.

    I've seen and photographed many an F-22 in flight. However, the no pictures rule for the F-22 when I was up there was because the plane was in the maintenance hangar with access hatches open and various sensitive gear visible. Those kinds of "looks" are not encouraged right now...

    Well, given that the F-22 has made more than one appearance in Japan, I am certain the Japanese government is interested. However, this raises more than a few issues, specifically related to technology and sociopolitical issues as well. The JDAF (Japanese Defense Air Force) has been so named as it has been a Japanese Constitutional issue that their armed forces are for defense only and not aggression. The interesting thing about stealth technology however, is that it is almost exclusively used for aggression rather than defense if you play your strategy according to tradition.

    I got a quick tour of the F-22, but no pictures allowed of the F-22 during my last visit up to Hill AFB and the F-22 is making the rounds and is being explored for possible basing in other countries, but there are technology sales issues with the aircraft as it will be almost impossible to strip the sensitive technologies out of the aircraft and make it "saleable".

I suspect what it is doing is making flying more inconvenient for the traveler, more expensive for the airlines, reducing businesses ability to function and more because let's be honest here.... It is not hard to imagine any number of amazingly effective scenarios that terrorists could use that would be far more effective than focusing on airports, so quit with all of the panic reactions already.

    Ah, I suspect this was either not a meteorite or there is something else going on given that any meteor leaving a 30 meter wide and 20 foot deep crater (meteor being approximately 30 inches wide) is not going to hit the ground steaming hot. On the contrary, it will be cold as ice (or colder) given its composition and time for heating. However, I suppose it could also be a re-entry event from a satellite carrying a toxic payload like plutonium... After all, we have the remnants of many satellites and the debris associated with them still in decaying orbits and you can easily spot many of them. Some satellites particularly those from the former Soviet Union and China have a history of toxic components. Though I suspect we'll know soon enough if it were a satellite, it would have been tracked by numerous agencies and individuals who monitor that sort of thing.
