Abstract: A 2 DOFs decoupling parallel mechanism provided by the present disclosure comprises a fixed platform, a rotation assembly, a moving platform, an arc kinematic chain, and an arc rod. In the 2 DOFs decoupling parallel mechanism, the rotation assembly can drive the moving platform to rotate by 360 degrees around a direction being perpendicular to the fixed platform, the arc rod reciprocates along the tangential direction of the arc kinematic chain to enable the moving platform to rotate around an axis of a plane where the arc kinematic chain is located. In this way, the rotations of the moving platform in two directions are respectively driven by driving units in two directions and being independent from each other, such that the two rotation actions of the mechanism have decoupling capability.

The method of oxidative regeneration provides an efficient way for the recovery of the saturated adsorbent.

Abstract: A method and apparatus for caching a data block are provided. The method includes: obtaining, from a terminal, an access request for requesting access to a first data block; determining that the first data block is missed in a cache space of a storage system; detect whether a second data block satisfies a lazy condition, the second data block being a candidate elimination block in the cache space and the lazy condition being a condition for determining whether to delay replacing the second data block from the cache space according to a re-access probability; determining that the second data block satisfies the lazy condition; and accessing the first data block from a storage space of the storage system and skipping replacing the second data block from the cache space.

Abstract: A security chip includes: a first medium layer; a second medium layer disposed on the first medium layer, where the first medium layer is an optically denser medium relative to the second medium layer, and a roughness of an upper surface of the first medium layer is greater than or equal to a preset threshold, so that light entering the second medium layer from the first medium layer is able to be totally reflected and/or scattered; and a semiconductor chip disposed on the second medium layer. Based on the above technical solution, light incident from a lower surface of the first medium layer is able to be totally reflected or scattered by the upper surface of the first medium layer, so that most of light cannot reach a logic or storage area on the front of the security chip, thereby achieving the purpose of resisting a laser attack.

Abstract: A device is capable of filtering animal waste with an improved sifting method. The device includes a support bracket, a chamber attached to the support bracket, and a screen filter located within the chamber when the animal deposits the waste. The chamber has an opening adapted to accommodate the animal to deposit the waste inside the chamber. The chamber is rotatable between a first position and a second position. The screen filter is movable between a third position and a fourth position. The rotation of the chamber and the movement of the screen filter can be independently managed, thus achieving a better result of animal waste handling.
