  1. Re:Wow, they forgot the most successful MEMS! on Shining Light On (And Through) MEMS · · Score: 2
    Sorry to reply to my own post, but a few followup points:

    My calculations should end up with approx. 2 Gbit/sec. (Gbps) throughput.

    TI has already demoed a full SXGA (1280 x 1024) 24-bit resolution all-digital graphics display which handles 1.89 Gbit/sec. throughput. See this PDF.

    Perhaps because the focus of the article was on optical switching, whereas TI DLP developers focus on display technologies & color printing. Although there could be some overlap between these approaches (why not just shoot a video image down a fiber pipe w/DLP repeaters?), right now there isn't really any.

    Here are some basic theoretical bandwidth calculations for DLP / DMD (cribbed from some TI whitepapers - but any lousy math is my fault):

    theoretical minimum frame time ... is in the range of 10 to 20 microseconds [50-100 kHz!]. This would mean that a DMD pulsewidth modulation system delivering full light efficiency could achieve over 10 bits of dynamic range.

    In particular, pulsewidth modulated SLMs can have bandwidth constraints that limit the system's ability to display the number of bits necessary to eliminate these contours. This limit is set by the switching speed of the mirrors (nearly 18 microseconds) and the data input structure of the DMD. With the current input structure and memory-multi-plexed DMD architecture, the DMD can display 8 bits per color in a 60 Hz sequential color system. In three-DMD configurations, more than 10 bits are possible. One can only determine the number of bits or grayshades necessary when considering the resolution, brightness, and contrast ratio of the display.

    2048 x 1152 mirror resolution has been demonstrated. Thus peak throughput bandwidth would be:

    2,359,296 bits ~= 2 Mbit(assuming each mirror is one bit)
    x
    10 bits (dynamic range via pulse width modulation - most current single-DLP systems are in the 8 bit realm; three-DLP systems obviously get 24 bit color)
    x
    100 kHz (note most current DLP systems work at 50-60 Hz)
    ~=
    2 Gbits throughput (plus error checking, overhead etc.)

    Not exactly ready to switch OC-192's and up. I think the real problem is detection on the other end - how do you recognize the subtle color shifts in real time with this kind of bandwidth (our parallel-processing wetware is pretty good at this, admittedly).

  6. Re:Ornithopers on On The Dune Miniseries · · Score: 2

    I was actually about to post such a comment myself, but now I'll save the trouble. I suppose the maneuverable stabilators with vectored thrust fans were a fairly reasonable interpretation. However I do think actual flapping-wing ornithopters were what Herbert intended in the novels; probably as another Baroque/Renaissance era evocation (cf. Leonardo, etc.). Here are some supporting points:

    1. Advanced materials (e.g. nanocomposites?) would presumably be available with the necessary strength-to-weight ratios for birdlike flight.

    2. The desert climate on Arrakis would provide significant thermal updrafts, which a large winged craft could use to stay aloft with minimal power. Add flapping and you get even more cruise time & maneuverability. And they almost certainly had high-efficiency, tiny power plants available.

    3. Don't forget the whole Mentat angle - since the NeoLuddites (name?) trashed all the computers, basically all of science & math had to be reimplemented using only human minds. Maybe flapping wings seemed more natural or easier to develop (after all that's what most pre-Wright Bros. designs for powered flight seemed to try). Maybe they never rediscovered Bernoulli's work, and thus the properties behind the fixed wing's lift.

Bush Sr. was bad enough, but at least a Dem House counterbalanced him & managed to get things like the Clean Air Act passed (which Dubya has consistently ignored in Texas).

    Oh yeah, I forgot to explain a few things (most of you probably already know about these so feel free to skip it)...

    The PPPoE move is to limit their rapidly dwindling pools of DHCP IP addresses. Apparently lots of folks are connecting Ethernet hubs to their DSL bridges and snarfing more than their allotted single dynamic IP with multiple machines on a home network. They are trying to sell those folks the more expensive 5-static-IP blocks. I don't know if you can use NAT/DCHP and PPPoE together on a BSD or Linux firewall box to get around all of this.

    The rate limiting on news/mail was a particularly galling move, but again it is technically SWBell.net (SBIS) the ISP doing this, not SWBell.com (SBC) the DSL provider.

    Just my $0.02: SWBell the ISP is much less clueful than SWBell the Telco/xDSL provider, in my experience. So you may want to go with SWBell for DSL but if possible stay away from the ISP side.

    Unfortunately I have had them as my dialup ISP for years now and don't want to go through the hassle of changing e-mail addresses, etc. again (it was bad enough when I ditched NetCom way back when - anybody remember NetCruiser?). I got a pretty good deal by signing up for a combined swbell.net ISP and DSL deal - 1.5 down/384 up, single dynamic IP, at around $40/month, free install & equip. (NIC, DSL modem, cables, splitters) w/1 yr. commit. The two (2) techs (!) they sent out to install were really on the ball-they rewired some taps, etc. to get me going at the full rate, and did a great job.

    Of course they also tried to keep charging me for dial-up after I cut over (a few phone calls fixed that). In general the left hand doesn't know what the right hand is doing over there - their tech support will walk you through all the clueless newbie troubleshooting steps every time you call, even when you KNOW it's got to be a problem on their end (several times they have had to reset the DSLAM to get me back up & running - nothing was wrong on my end at all, despite their initial protests). However SWBell has apparently outsourced most of their xDSL hardware support to another company (can't remember the name, but I think they handle all of SBC (SWBell + PacBell) DSL tech support at this point), so maybe that explains it. Also, they are trying to cut everybody off of plain ADSL with DHCP and are signing new home users up only with PPPoE (which means you must use their Win or Mac PPPoE software, or figure out how to run PPPoE on Linux). Finally, they recently rate-limited downloads from mail and news servers to 384k which put a severe crimp in my alt.binaries.* habit....

  14. It's about time! on Guiding Air Traffic Sans Radar With GPS · · Score: 2
    We need better technology for ATC; this summer's rash of delays and near misses has shown the strains of the current system nearing its breaking point. Giving the pilots and traffic controllers better information is always a plus. Also, this system (if properly designed) should only enhance the current centralized system with its additional decentralized data points. However, it should definitely undergo rigorous and thorough testing before being widely deployed and relied upon for passenger safety. The ideal system would have radar, GPS, weather and map data integrated in real time on an intuitive display (perhaps a HUD?). After viewing the ADS-B demos I am encouraged but I don't think it is all the way there yet.

    Disclaimer: I am extremely biased in this area, due to the fact that my father was killed in an airline crash in April 1977 (read all about it in Chapter One of Air Disaster (Vol. 2), by Macarthur Job). The main problem there - the plane flew smack into the worst part of a severe thunderstorm, which onboard weather radar showed as a clear spot. Both engines died, and despite having three airfields relatively close by, they attempted to land on a two-lane country highway. Admittedly both ground and airborne radar systems have come a long way since then, but they are still not enough. GPS might have let them know where the closest airport was in time, if not warning them off from the storm in the first place. If a real-time ground-based color Doppler radar display could be piped into the cockpit, along with accurate GPS positioning, I would think quickly developing weather systems would be much less dangerous for all classes of aviation. However, the bandwidth problems for something like this might be insurmountable for quite a while, despite this company's claims.
