A power storage device electrode is provided, which includes a layer made of a composite material containing an organic sulfide compound as an electrode active material and a sulfide-containing organic polymer as a binder, and a current collector stacked on the layer. Through the use of an interface, the approach eliminates numerous outdated, if not antiquated, parts, including safety locks, mechanical disconnect switches, E-stop safety relays, and safety Programmable controllers. Preemption data periodically received by the computer system from at least one preemption controller at a respective intersection is used to update the road map. The one or several loudspeaker signals may be established such that, when reproducing the one or several loudspeaker signals, the position of the object in the reproduction space is displayed acoustically.
