  1. A former college quarterback has invented a football helmet with a radical
    new design.
    http://www.nytimes.com/2007/10/27/sports/football/27helmets.html?pagewanted=1&_r=1&th&emc=th

    'Rather than being lined with rows of traditional foam or urethane, Ferrara's
    helmet features 18 black, thermoplastic shock absorbers filled with air
    that - not unlike his squirt bottle - can accept a wide range of forces and
    still moderate the sudden jarring of the head that causes concussion.
    Moreover, laboratory tests have shown that the disks can withstand hundreds
    of impacts without any notable degradation in performance, a longtime
    drawback of helmets' traditional foam."

    Disclaimer: I'm not trying to start a discussion on the merits of wearing a
    helmet. I know the usage of football helmets (where you might get hit
    several times in a couple of hours) is different than bicycle helmets (where
    you are most likely to go years without the helmet getting any contact).
    This is a newsgroup, though, and this sounded like news.

    I try to avoid buying running shoes that have air pillows in them,
    because it's been my experience (a couple times) that the air pillows
    must be filled under /pressure/, and that pressure tends to leak out
    relatively quickly--in my experience, in only about a month of use both
    times. The shoes worked great when they were brand-new, but after they
    had gone flat I was wondering why I paid $100 a pair for them.

    Sorbothane (soft urethane) is pretty shock-absorbent, and basically
    flat-proof. It /is/ a bit heavy however.

    Regarding running shoe technology: Nike recently started marketing
    marketing the Free shoe (http://www.nike.com/nikefree/) to mimic, as
    much as possible, barefoot running.

    Supposedly, the rationale was twofold: first, it was observed that
    runners who ran barefoot at least part of the time, ran faster.
    Second, it was observed that Nike (and competitors) had worked for
    decades to design and build ever-more-protective footware, yet runners
    were getting foot and leg injuries at the same rate.

    IOW, all the fancy, advertised, "scientific" protection didn't work.

    Parallels are left as an exercise for the reader. ;-)

    I neither run nor play tennis, but isn't this the same reasons that tennis
    balls go "dead" after a relatively short time of use -- and why they ship in
    pressurized containers in the first place?

    I find the description lacking in that it doesn't explain that the air
    cushions are not pressurized but rather full of air that compresses
    under shock loads and is allowed to escape through a metered vent to
    absorb even greater displacements. I also would like to see a
    force/time graph comparing a conventional helmet with this design
    showing both acceleration and displacement.

    If it works as the six phases (step through them) shown on this web
    site, it is a great improvement.

    I am also interested primarily in the technical aspects of the design.

    Great--so now they're going to go back to making flat-sole plain rubber
    shoes, but still charge $100/pr for them.

    I suspect that running is just a cause of injuries within itself--even
    racehorses suffer non-collision injuries doing it. I'd be willing to bet
    that (as far as injuries sustained from running) about 60% is genetic,
    30% is diet and the other 10% is actual training or lack of it. The more
    we learn about genetics, we will find the less decisions we can claim
    responsibility (or credit) for.

    And ultra-marathoners having their toenails removed is just damned
    creepy, there ain't no other way to say it.

    Bah! Get back to me when someone kills two birds with one stone and
    designs a helmet that will carry/use my spare tube as the shock absorber.

    I think there should be some mileage in a deformable metal mesh (like
    thick chicken wire) over a light skeleton, just to hold it in place.
    That might get round the ventilation issue, although the chin strap
    would still be the main source of discomfort for me.

    Government puts brake on MP's helmet compulsion campaign
    10:45, Oct 23rd 2007 by Carlton Reid
    Minister says helmet compulsion unlikely because it leads to decreased
    cycle use
    Peter Bone, the Tory MP for Wellingborough and Secretary of the All-
    Party Road Traffic Group, wants all under 14 year olds to be forced to
    wear helmets when cycling. In a 10 Minute Bill on October 16th he
    argued his case and has subsequently raised the matter again in
    Parliament.

    However, Jim Fitzpatrick, a Parliamentary Under-Secretary at the
    Department for Transport, said:

    "We have no proposals to bring forward legislation on compulsory cycle
    helmet wearing...A 2002 review commissioned by the DfT concluded that,
    overall there is evidence that bicycle helmets can be effective at
    reducing the incidence and severity of head, brain and upper facial
    injuries... However, the report also concluded that, making cycle
    helmet wearing compulsory may in some cases discourage some people
    from cycling, leading to decreased bicycle use."

    Fitzpatrick stressed that at the current levels of helmet use,
    enforcement would be a problem. Teenage boys, in particular, are
    eschewing helmets and forcing this group to wear helmets would make
    many turn away from cycling. Such a result would be a net loss to the
    health of the nation because the amount of lives saved by helmet
    compulsion would be dwarfed by the loss of life caused by sedentary
    lifestyles.

    "Our regular surveys of helmet wearing rates show that cycle helmets
    were worn by 28 per cent of all cyclists on major roads in built up
    areas in 2004; this compares to 16 per cent in 1994." said
    Fitzpatrick.

    "The corresponding figures for child cyclists are 14 per cent in 2004
    compared to 18 per cent in 1994. The wearing rate for teenage boys has
    decreased from 16 per cent to 11 per cent. The 2006 helmet wearing
    rate survey will be published later this year.

    "While compulsion remains an option that we will review from time to
    time, it has been our view that, at current helmet wearing rates,
    making helmets compulsory would cause enforcement difficulties and
    without greater public acceptance could have an effect on levels of
    cycling."

    Roger Geffen, CTC's Campaigns and Policy Manager, said:

    "Peter Bone's wish to 'do his bit' for safer cycling is no doubt
    sincere, but totally misguided. He has blinded himself to the mass of
    data showing that helmet laws drastically reduce cycle use and that a
    cull of cyclists only makes things worse for those who remain. With
    new evidence just out showing that the obesity crisis is far worse
    than we had previously realised, it is clear that Bone's proposals
    would shorten thousands more lives than they could possibly hope to
    save."
