    • A system and method for automated determination of position and movement of a contact lens with respect to a subject wearer's eye based upon a complimentary pair of images, acquired in rapid succession, in which one image of the pair is acquired using light that allows viewing of the pupil and/or limbus through the lens and the other image is acquired using light that is absorbed by the lens to generate an opaque image with a defined edge relative to the surrounding sclera. The images of the pair are acquired in close enough temporal proximity to ensure that eye movement in the interval therebetween is insignificant and both images are in the same approximate reference frame. Thus, the location of the pupil and limbus in one image can be accurately compared with the location of the contact lens edge in the other image.
    • 一种系统和方法,用于基于快速连续获取的互补图像,自动确定隐形眼镜相对于被摄体佩戴者的眼睛的位置和运动,其中使用允许观看 通过透镜和另一图像的瞳孔和/或角膜通过被透镜吸收的光来获得,以产生具有相对于周围巩膜的限定边缘的不透明图像。 以足够接近的时间获取该对的图像,以确保其间的间隔中的眼睛移动是无关紧要的,并且两个图像在相同的近似参考系中。 因此,可以将一个图像中的瞳孔和角膜缘的位置与另一图像中的隐形眼镜边缘的位置精确地比较。

    • The present disclosure discloses a method, a system and a server of removing a distributed caching object. In one embodiment, the method receives a removal request, where the removal request includes an identifier of an object. The method may further apply consistent Hashing to the identifier of the object to obtain a Hash result value of the identifier, locates a corresponding cache server based on the Hash result value and renders the corresponding cache server to be a present cache server. In some embodiments, the method determines whether the present cache server is in an active status and has an active period greater than an expiration period associated with the object. Additionally, in response to determining that the present cache server is in an active status and has an active period greater than the expiration period associated with the object, the method removes the object from the present cache server. By comparing an active period of a located cache server with an expiration period associated with an object, the exemplary embodiments precisely locate a cache server that includes the object to be removed and perform a removal operation, thus saving the other cache servers from wasting resources to perform removal operations and hence improving the overall performance of the distributed cache system.
