这才是真正的无线充电:Cota By Ossia借助类Wifi频谱的电磁波实现零接触充电

橙皮书 · 2013-09-10
据说疯子科学家Tesla曾经想做一个全球无线电能网络,建成后这个世界就不需要电线了。我没有认真去考证,但是从理论上看是可行的。现有的几种无线充电方式则没这么浪漫,Qi是需要把手机放在充电器上接触才行的,易用性上还算凑合吧,小部件是够用的;Magnetic resonance(磁共振)则更适合大型设备,比如电动车。


据说疯子科学家Tesla曾经想做一个全球无线电能网络,建成后这个世界就不需要电线了。我没有认真去考证,但是从理论上看是可行的。现有的几种无线充电方式则没这么浪漫,Qi是需要把手机放在充电器上接触才行的,易用性上还算凑合吧,小部件是够用的;Magnetic resonance(磁共振)则更适合大型设备,比如电动车。

今天在TC Disrupt大会上亮相的Cota By Ossia有点小亮了。这家公司已经做了好几年了,一直是潜行模式,官网上啥信息都没有,这次是他们首次亮相。CEO Zeine说他们的技术是利用跟Wifi、Blutooth、Zigbee近似频谱的电磁波来传输电能的,安全,容易被大众接受,对人体的影响跟Wifi差不多,覆盖范围也是如此。演示到一半时,他撩起原型机上遮盖的帘子,乖乖,敢情是一大箱路由器呢。

开玩笑的。从现场演示来看,Cota现在可以捕捉到充电模块的位置,然后将能量汇聚到这一点,如果移动充电模块,系统需要一段时间才能重新定位。Zeine先是让一个小灯泡亮了起来,然后换成iPhone也点亮了屏幕,瞬间大家都沸腾了。以后成熟的产品会改进智能定位,实现连续地无线充电。也就是说,只要你家里有无线充电,在室内你的手机会一直是满电。

这款产品要面世可能得等2015年,消费者版的价格大概在100美元以上,体积也会大幅减小,可能跟台式机机箱差不多大。Cota自己会生产硬件,也会开放授权给其他厂商,目的就是尽可能占领市场。

“相机”和“拍照快门”从诞生之日起似乎就是对连体婴。但是,在自拍场景下,快门的存在似乎有些碍事。美女们既要关注取景和构图,又要伸长手指按快门,一不小心手抖一下,脸部再紧张一下,一秒美女就被悲催地打上了“马赛克”。定位女性自拍应用的“伊拍”则试图利用人脸识别技术解放按快门的手指:笑一笑,做个V手势,说声“拍”,所有这些动作在伊拍上都能替代快门实现无接触拍照。
