... The difference between analog and digital dictation machines is that analog devices immediately store dictation to tape media in real time. This means there are no open files needing protection. Therefore, if the batteries are depleted, the analog media can simply be placed in another machine for pl ...

Charge Allocation for Hybrid Electrical Energy
... Electrical energy is a high quality form of energy [1] in the sense that it can easily and efficiently be converted into other forms of lower quality energy. Electrical energy consumption generally fluctuates over time according to variation of the load demands (e.g., an information processing or co ...

Grid energy storage
Grid energy storage (also called large-scale energy storage) refers to the methods used to store electricity on a large scale within an electrical power grid. Electrical energy is stored during times when production (from power plants especially intermittent renewable electricity sources such as wind power, tidal power, solar power) exceeds consumption and when additional discretionary load is turned on but consumption is still insufficient to absorb it.
