The present invention generally relates to certain lithium materials, including lithium manganese borate materials. Such materials are of interest in various applications such as energy storage. Certain aspects of the invention are directed to lithium manganese borate materials, for example, having the formula LixMny(BO3). In some cases, the lithium manganese borate materials may include other elements, such as iron, magnesium, copper, zinc, calcium, etc. The lithium manganese borate materials, according to one set of embodiments, may be present as a monoclinic crystal system. Such materials may surprisingly exhibit relatively high energy storage capacities, for example, at least about 96 mA h/g. Other aspects of the invention relate to devices comprising such materials, methods of making such materials, kits for making such materials, methods of promoting the making or use of such materials, and the like.

Disclosed herein is an apparatus for providing spatial contents service which includes a spatial contents insertion unit, a spatial contents generation unit, a topological relationship generation unit, and a spatial contents composition unit. The spatial contents insertion unit extracts spatial objects included in an image. The spatial contents generation unit generates primary spatial contents corresponding to the image. The topological relationship generation unit compares spatial location information of the primary spatial contents with spatial location information of one or more pieces of secondary spatial contents, and defines a spatial topological relationship between the primary spatial contents and the secondary spatial contents. The spatial contents composition unit couples or links the secondary spatial contents, which has a spatial topological relationship with the primary spatial contents, to the primary spatial contents.

Provided is a method for creating a 3-D curved surface by using corresponding curves in a plurality of images. The method includes performing an NURBS fitting curve with respect to one image in a plurality of images having camera calibration and extracted camera parameter by using control points designated in a curve characterizing a subject shape. When the curve fitting is performed with respect to the curve that commonly exists in more than two images, a 3-D curve is created by using a camera calibration information, or a 3-D curved surface is created by creating a plurality of 3-D curves or straight lines. Therefore, a 3-D curved surface model can be easily and quickly created by simplifying a complex modeling process for an actual object modeling into an actual image-based modeling process.

A method for modeling a three dimensional shape of object using a level set solution on a partial differential equation derived from a Helmholtz reciprocity condition is provided. The method includes the steps of: a) inputting an image pair satisfying a Helmholtz reciprocity condition; b) performing an optical correction and simultaneously performing a geometric correction; c) performing a camera selection to select cameras capable of seeing a point (X, Y, Z), and defining and calculating a cost function by the Helmholtz reciprocity condition; d) calculating a speed function of a PDE that minimizes the cost function obtained in the step c); and e) generating a three dimension mesh model from a set of points configuring the object surface provided from the step d), and deciding a final three dimension mesh model by comparing cost function values.
