  • Publication number: 20140362287
    Abstract: The present invention is related to a multi-directional positioning apparatus for mobile-phone camera shooting, in particular, to a multi-directional positioning apparatus capable of clamping and positioning a mobile phone in a reverse orientation and capable of adjusting angles for the camera lens at temporary positions of eye-level angle (0°), low or high angle such that shots at different angles are taken at predefined angles under temporary positioning in 360° rotation. The multi-directional positioning device allows the mobile-phone lens to be temporarily positioned at eye-level (0°) for taking camera shots at predefined angles under temporary positioning in 360° rotation; and allows the mobile-phone lens to be at temporary positions of low or high angle for taking camera shots at predefined angles under temporary positioning in 360° rotation; and accordingly, these camera shots can be further combined by image software to form 360° cylindrical VR or 720° spherical VR panoramic shots.

  • Patent number: 8869084
    Abstract: A method for generating a layout for a cell of an integrated circuit (IC) guided by design rule checking (DRC) is disclosed. In the method, a model is defined, wherein the model comprises a plurality of parameters for generating a layout of the cell. Next an initial layout for the cell can be generated according to an initial set of values for the plurality of parameters. Then design rule checking (DRC) is performed for the initial layout based on a set of design rules. If any violations are found, the corresponding violation reports will be associated with the model. Therefore, a new set of values for the plurality of parameters can be generated by analyzing the violation reports collectively based on the model. With the new set of values for the plurality of parameters and above steps repeated, until no violation is found, a “DRC clean” layout can be generated.
