Abstract: A novel energy storage battery system is described that includes a highly reversible electrolytic Zn—MnO2 system in which electrodeposition/electrolysis of Zn (anode side) and MnO2 (cathode side) couple is employed with a theoretical voltage approximately 2 V and energy density of approximately 409 Wh kg?1 providing superior durability and excellent energy densities.

Abstract: A method for adjusting lens position, includes: controlling a lens in a photographing component to be sequentially located at m first lens positions during a focusing process, and acquiring a first definition of an image captured by the photographing component at each of the first lens positions, where m?3; selecting a first relationship curve in a focusing curve library according to a matching condition, the focusing curve library including at least two relationship curves between definitions and lens positions captured at different focusing distances, and the matching condition being used to indicate a degree of similarity between the m first lens positions as well as the first definitions and the relationship curves; and controlling the lens to be located at a target lens position corresponding to a maximum definition indicated by the first relationship curve.

Abstract: A hierarchical circuit design is divided into independent components which can be processed independently of one another to simultaneously achieve the advantages of both hierarchical and flat paradigms. Blocks of the circuit design are flattened sufficiently to place and route global networks through the blocks. The flattened blocks of the circuit design are de-coupled to form independent blocks. In de-coupling the blocks, pins are added at intersections of the global networks with boundaries of the blocks. The global networks are divided into wire fragments between the pins and components of the flattened circuit design in generally the same place previously occupied by the global networks. Wire fragments inside a particular block of the circuit design are added to the block. Wire fragments outside all blocks are fixed as components of the circuit design. The blocks are therefore de-coupled at the pin positions along the block boundaries.
