A method is provided for determining cellular electrical potentials using a state estimator. The state estimator is generated using at least an electrical source model and an electrical conduction model. One or more parameters or states of the state estimator are adjusted based on a measured electrocardiographic and/or a measured body-surface-potential signal. The electrical potential of one or more cells is determined based on the one or more adjusted parameters or states. In one aspect of the present technique, one or more representations of an organ comprising the one or more cells is generated such that the electrical potential or its deriving characteristic of the one or more cells is visually indicated.

摘要:
A storage energy generation method utilizing natural energy and a generation system thereof generates electricity through natural energy such as wind power or solar energy and then compresses air, or directly compresses air, then generates electricity to an electric grid through the compressed air which is deemed as a power resource. An electric station utilizing integrated energy generates electricity to drive an air compression device, further then produces compressed air as an energy storage medium and stores compressed air in an air storage device, and then regards the compressed air as a main or auxiliary driving energy to other electric stations, such that a function of stabilizing and adjusting peak load can be realized.
