The One True Translation

Isn't it interesting what a name implies??

    Have I been running lately?  Nope.  But this post is not about running.

    About 4 months ago I had an idea.  Now, I have ideas all the time - but as I told my boss awhile ago at work "it needs to be worth pursuing".  I feel strongly enough about this idea that I've spent a considerable amount of time on it over the last several months.  I've taken close to 2 weeks of leave from work, and lost countless hours of sleep because I refuse to take time from the family.

    I can't show it off yet but I do have a proof of concept up an running. I can say that it involves crawling portions of the Internet.  A web crawler is a robot that starts with a list of web pages, downloads them, finds the links in those pages and adds those newly found links to the download queue.  My starting list of sites to crawl is ~35,000 domains long.

    Now by comparison the big guys ( Google, Bing, Yahoo, Baidu ) are most likely crawling & indexing all 130 million registered domains.

    Luckily for me my ISP does not have a bandwidth cap - though I am on DSL, so I can't ultimately use that much.  Last month I was able to pull ~150 gigabytes in.  I'm hoping to do double that this month.

    When my index gets big enough to be useful I'll open it up and we'll see how useful people will find it.

    120 Band-aides

    Today we did a high density EMG, ~120 sensors in a grid over my entire residual limb.  The goal was to map out all the motor units for about a dozen different motions - including big toe up & down.  The goal as I understand it is to push the limit and determine how much information can be gathered from the re-innervated sites + the muscles in the rest of my residual limb.

    After all of the signals have been processed it should result in some pretty cool graphics, communicating what things are firing when I think about doing various motions.

    I've asked for a copy of the ~1.5 GB of data gathered, but I'm not sure if they can give it to me.  I'd love to crunch it myself.  I don't think they've had a patient quite like me.  :-)

    Oh, and yes it felt like pulling off 120 Band-aides, one at a time when we were done.

    Hi-Tech leg fun

    This week I'll be in Chicago at RIC, Center for Bionic Medicine doing some experiments with neural controls for powered prosthetics.

    Today I had 24 EMG sensors on my stump for ~ 6 hours.  We did various iterations of gathering data, traning classifiers, checking classifier accuracy against more gathered test data, then using those classifiers to realtime control a virtual limb.  By the end of the day I was able to fairly accurately control flexion & extension of both my lower leg & ankle ( on a virtual avatar, mechanical devices to come later ).  Very cool stuff.

    Sunday runs

    My good friend Greg Ireland has taken over leadership of our churches youth group - and he has convinced me to hang out with them sunday night.  I'm excited about the oppertunity to get to know the kids there!

    We've decided that after everyone leaves on Sundays we're going to run.  Greg pushed me a bit and we put in 2 miles ( with a couple minute rest in the middle ).  Fortunately for my ego Greg wore way to many cloths and consequently broke a sweat.  Wow was I sore on Monday, my right quadriceps were very mad at me.  On the bright side some of my goals - though far away - are seeming achievable now.

    Peglegs & Pirates

    I realized there was only one sensible thing to do for this Halloween - make a peg leg.  I got some serious double takes at a local carnival, even had a kid ask me "are you holding your leg up?"

    1 mile - its all about the speed

    So I finally ran 1 continuous mile, no stopping, no walking, no crashing.  I had to take a knee, thank my God, shed a tear ( seriously ) and catch my breath.  :-)

    Some of the recent changes to the running foot have made it possible for me to go considerably slower.  Running at a slower cadence, and shorter stride keeps me from becoming anerobic so quickly.  So ultimated its a combination of training, prosthetic changes, and running slower that has allowed me to push the distance up fairly quickly.

    More on the news front, I'm scheduled in early December to go help with a research project at RIC.  They are building and studying the best way to control a powered prosthetic leg controlled using the targeted reinnervation's that were done when my leg was amputated.
