A method and a system for controlling transmission power which recover a target SIR calculated on a terminal station side from a state where it has become excessively large to a state where the target SIR is normal as quickly as possible are provided. In one embodiment, the energy storage apparatus includes i) a plurality of battery trays arranged substantially parallel to each other so as to form at least one row and ii) a first duct located at a first side of the battery trays, wherein a plurality of first openings are formed in the first duct. The two video camera sensors can be either of similar or two different modalities each possibly with a different field-of-view. On the lower side of the circuit board are two ring-shaped copper wires. A filter having a capacitor with capacitor-path inductance cancellation provides enhanced performance over frequency compared with conventional capacitors.
