Computer scientist Shwetak Patel and his team are developing new sensing systems.The initial focus was really around energy and water monitoring.They built a new generation of smart sensors that monitor electronic interference on a home’s power line or water pressure changes in the plumbing.Most of this technology has already found industrial applications.And Patel and his team turned their attention to adapting the technology for personal health monitoring.


计算机科学家Shwetak Patel和他的团队正在开发新的传感系统。最初的重点是能源和水的监测,他们建造了新一代的智能传感器来监测家庭电力线路上的电子干扰或管道中的水压变化。大多数这项技术已经在工业上得到了应用。帕特尔和他的团队把注意力转移到了将这项技术应用于个人健康监测上。

So how do we take this noise and make it into a signal of interest?That was a kind of the core of what we did for many years.And we’re taking that work and applying it to other domains.They’re looking to take advantage of all the functionality built into our smart phones.With the users permission,this App can use the microphone,built into most smart phones,to listen to background noises,such as coughing,searching for patterns that suggest a trip to the doctor might be an order.We construct these models that try and understand how sound works,how it what its patterns are?And we give it a whole bunch of examples of different kinds of audio,things like people talking,things like people laughing,sneezing and of course coughing.This App uses a phone’s camera to check haemoglobin levels in blood by analyzing the color of capillary fluids through the skin.


那么,我们如何将这种噪音转化为一种有趣的信号呢?这是我们多年来所做工作的核心。我们把这项工作应用到其他领域。他们希望利用我们智能手机内置的所有功能。在用户允许的情况下,这个应用程序可以使用大多数智能手机内置的麦克风来收听背景噪音,如咳嗽,搜索提示去看医生可能是命令的模式。我们构建这些模型,试图理解声音是如何工作的,它的模式是什么?我们给出了一大堆不同类型音频的例子,比如人们说话,人们大笑,打喷嚏,当然还有咳嗽。这个应用程序使用手机的摄像头通过分析皮肤中毛细血管液体的颜色来检查血液中的血红蛋白水平。


Generally what happens is if you’re anemic your bloods are going to be a little less red,and we take advantage of that by putting your finger over a camera of a phone,the camera of the phone can actually see the coloration of the blood.And this test uses the camera tell parents worried about jaundice in newborn infants.Now jaundice is something that doctors who have seen tons of babies,it just can figure out on a very basic level of;is this baby,do they need get treatment or are they in a good condition,where as a first-time parent has no idea necessarily what jaundice might look like.


一般来说,如果你贫血的话,你的血液会少一点红色,我们利用这一点,把你的手指放在手机的摄像头上,手机的摄像头实际上可以看到血液的颜色。这个测试用摄像头告诉父母担心新生儿黄疸。现在黄疸是一种症状那些看过无数婴儿的医生们,只能从一个非常基本的层面来判断;这个婴儿,他们需要接受治疗吗,或者他们的状况是否良好,作为一个第一次做父母的人不知道黄疸可能是什么样的。
