  • Patent number: 8264246
    Abstract: A method for determining characteristics of a multi-material object is provided. The method includes producing a rotating electric field by providing an applied electrical signal set of individual electrical signal patterns to electrodes surrounding the multi-material object. The method also includes obtaining a measured electrical signal of electrical signals from the electrodes corresponding to each electrical signal pattern applied. An electrical network is determined based on the applied electrical signal set, the measured electrical signal set and an inverse of the applied electrical signal set. The method further includes determining the characteristics of the multi-material object by analyzing the electrical network.

  • Patent number: 8121804
    Abstract: A method for determining characteristics of a multi-material object is provided. The method includes determining an electric element matrix representing the multi-material object. The electric element matrix is pre-multiplied by a first mathematical transformation matrix to obtain a first transformed electric element matrix. The first transformed electric element matrix is post-multiplied with a second mathematical transformation matrix to obtain a second transformed electric element matrix. The method further includes determining the characteristics of the multi-material object based on the second transformed electric element matrix.

  • Publication number: 20100086834
    Abstract: An energy storage device is provided that includes a separator having a first surface and a second surface. The first surface defines at least a portion of a cathodic chamber, and the second surface defines an anodic chamber. The cathodic chamber includes an alkali metal halide that forms an ion that is capable of conducting through the separator. The anodic chamber has a volume that is filled with a consumable fluid. The amount of the consumable fluid is greater than 90 percent by volume of the anodic chamber volume. Furthermore, the consumable fluid is reactive with an ionic species of the alkali metal halide. A method of sealing the energy storage device is also provided.
