摘要:
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.

摘要:
A method of providing an image of an interior of a structure (46) containing regions having different conductivities or admittivities. In one embodiment a series of electrical signal sets (V i ) is applied to a series of electrodes, each signal set generating a rotating electric field. A measured set of electrical signals obtained from the electrodes (44) is used to calculate a conductivity or admittivity distribution representative of the interior of the structure in a region about which the electrodes (44) are positioned. The process of calculating the distribution includes defining a cost function, e.g., the energy function based on the distribution, and a forward model expressing the measured set of electrical signals as a function of the change in voltage values with respect to conductivity or admittivity and requiring that the partial derivative of the difference between the energy function and a function based on the forward model equal zero.

A method (12) 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 (122). The method also includes obtaining a measured electrical signal of electrical signals from the electrodes corresponding to each electrical signal pattern applied (124). 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 (128).

摘要:
A method (101) and corresponding sensing system for determining characteristics of a multi-material object is provided. The method includes determining (102) an electric element matrix representing the multi-material object. The electric element matrix is pre-multiplied (104) by a first mathematical transformation matrix to obtain a first transformed electric element matrix. The first transformed electric element matrix is post-multiplied (106) with a second mathematical transformation matrix to obtain a second transformed electric element matrix. The method further includes determining (108) the characteristics of the multi-material object based on the second transformed electric element matrix.
