  • Modular electrical bus system with built-in ground circuit
    Patent number: 8256456
    Abstract: A modular electrical bus system has a grounding circuit through a plurality of modular units with each unit being both electrically and mechanically connectable together via a bridge member connecting adjacent units and the main communication module. The bridge member and modular units are grounded together with a ground circuit that extends within both components.
    Type: Grant
