But in order for us to actually realize the benefits of technology that can prevent concussion, it needs to meet regulations.
但為了真正利用這一可以預防腦震蕩的技術，它必須得符合監管的要求。
That's a reality. And this device is for sale in Europe but is not for sale in the US, and probably won't be any time soon.
這是個現實問題。這一設備目前在歐洲出售，但目前卻沒有、很可能近期都不會在美國出售。
So I wanted to tell you why. There are some good reasons and then there are some not so good reasons.
我會告訴各位這是為什么，有些原因很合理，而有些卻不是。
Bike helmets are federally regulated.
自行車頭盔由聯邦政府監管。
The Consumer Product Safety Commission has been given jurisdiction to approve any bike helmet for sale, and this is the test they use.
美國消費品安全委員會有權批準自行車頭盔產品上市，他們使用的是這樣的測試方法。
This is back to what I was telling you at the beginning about skull fracture.
這又回到了我們開始時候談到的顱骨骨折問題。
That's what this test is for. And that's an important thing to do.
而這正是這一測試的目的，這一測試很重要。
It can save your life, but it's not sufficient, I would say.
它能挽救生命，但我得說，它不夠全面。
So for example, one thing this test doesn't evaluate is it doesn't tell you is that airbag going to trigger at the right time and place,
比如說，這一測試沒有評估安全氣囊能否在正確地時間地點彈出，
and not trigger when it doesn't need to?
也沒有評估它在不需要彈出的情況是否會彈出。
Similarly, it's not going to tell you is this helmet likely to prevent concussion or not?
同樣，這一測試也不能判斷這一頭盔是否能夠預防腦震蕩。
And if you look at football helmets, which aren't regulated, they still have a very similar test.
其實橄欖球頭盔雖然未被聯邦政府監管，但他們的測試基本相同。
They're not regulated by the government, anyway. They have an industry body, which is the way most industries work.
雖然它們并未被政府監管，但如同絕大多數行業一樣，有一個行業機構負責此事。
But this industry body, I can tell you, has been quite resistant to updating their standards.
但我得說，這一機構極力反對更新它們的標準。
So in my lab, we are working on not only the mechanism of concussion, but we want to understand how can we have better test standards?
所以我們實驗室不僅研究腦震蕩機制，還想研究如何才能采用更好的測試標準。
And we hope that the government can use this type of information to encourage innovation
我們希望政府可以利用這類信息鼓勵創新，
by letting consumers know how protected are you with a given helmet.
讓消費者了解某一特定頭盔的保護能力。
