Abstract: The present invention provides a controller that operates using two different processors. Each processor performs certain predetermined functions. A control processor is responsible for switching AC power distribution and control, while a message processor is responsible for messaging. A polling scheme and arbitration logic prevent data transfers relating to these two processors from interfering with each other. A configurable interface allows many different types of appliances to attach to the system, and a serial multimode interface further enhances the configurability of the system.

Abstract: An improved ribbon cable connector is described for providing connection between an electrical device and a ribbon cable. Receptacle modules and a splice module having identical outer dimensions are provided for insertion into the cover of a receptacle tap. Each receptacle module contains receptacle sites for insertion of pins from an electrical device. Each receptacle site of the receptacle module is connected to an insulator displacement pin that is used to establish a connection with a conductor of a ribbon cable. A splice module connects pairs of insulator displacement pins together so that two different ribbon cables can be connected together in an efficient manner. Alignment projections on both the receptacle and splice modules allow for precise positioning of the insulator displacement pins within each module with the conductors of the ribbon cable.

Abstract: A electrical transmission line termination device capable of performing various termination requirements including matching the line impedance of wires in a transmission line with load impedances, electrically connecting conductors in a transmission line for maintaining electrical continuity, detecting improper wiring of the various wires in a transmission line, and connecting a cable shielding conductor to a ground wire.

Abstract: An automated gas distribution system for safely and reliably controlling the flow of gaseous fuel to gas appliances. The system implements a "closed-loop" delivery of gas, i.e., the gas is provided to a recongnized appliance only when that appliance sends a valid request for gas to a control/communications subsystem. Certain conditions preclude the supply of gas despite a valid request for gas and include an appliance or system malfunction, or a command from the system operator instructing the system to ignore certain gas requests. In addition, emergency conditions, such as a fire or gas leak will also circumvent the closed-loop delivery of gas to appliances.
