Abstract: A locking mechanism for removably locking a first electrical component to a second electrical component includes a positioning post secured to the second electrical component, a frame for mounting the first electrical component, and a locking member movably connected with the frame. The positioning post has a head and a neck. The locking member has a snap fastening portion, a flexible portion and an unlocking operated portion. When the snap fastening portion contacts the head and is moved toward the neck, a lateral thrust force exerted by the head spreads the snap fastening portion and cause deformation of the flexible portion to store a biasing restoring force. When the snap fastening portion is aligned with the neck, the snap fastening portion is moved by the biasing restoring force to be snap fastened to the neck. The unlocking operated portion is operated to disengage the snap fastening portion from the neck.

Abstract: A method of securely storing a target number is provided based on the Chinese-Remainder Theorem, A set of n congruence pairs of numbers are generated, wherein a target number (a secret) can be uniquely derived from any t out of the n pairs. In one aspect the divisors are pre-selected such that any randomly selected n integers from the sequence are a valid Asmuth-Bloom sequence for any access structure (t, n) where 1<t?n?N. In another aspect, means are provided for pre-storing members of a Mignotte or Asmuth-Bloom sequence of N divisors in a look-up table from which n divisors can be selected. In this way a flexible access structure is supported. CRT secret shares for a selected access structure can be generated without having to perform the laborious process of calculating Mignotte sequences for each secret and access structure. Storage required to store the secret shares is also reduced by storing and retrieving congruence pairs in the form of an index and a remainder.

Abstract: A three-dimensional (three dimensional) segmentation method with intensity-based Doppler variance (IBDV) based on swept-source OCT. The automatic three dimensional segmentation method is used to obtain seven surfaces of intra-retinal layers. The microvascular network of the retina, which is acquired by the IBDV method, can be divided into six layers. The microvascular network of the six individual layers are visualized, and the morphology and contrast images can be improved by using the segmentation method. This method has potential for earlier diagnosis and precise monitoring in retinal vascular diseases. Each tomographic image is composed of eight repeat scans at the same position, which achieves a high time difference to improve the sensitivity of the angiographic method. A subpixel registration algorithm is used to reduce the eye movement. The GPU was used to accelerate the data processing to achieve real-time preview of the acquired data.
