Abstract: A controller that operates using two different processors is provided. Each processor performs certain predetermined functions. A control processor is responsible for switching AC power distribution and control, while a message processors 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: The present invention uses a logic control to determine which of a plurality of processors receives priority, and generates WAIT signals for the non-selected processor. Further, user configurable pins exist that allow the user to determine the priority that the attached processor will obtain when simultaneous chip selects are transmitted.
Abstract: The present invention relates to an integrated outlet that allows supply of AC power to an outlet receptacle when certain conditions are satisfied. The integrated outlet contains separate modules establish electrical connection with electrical conductors that transmit AC and DC power, telecommunications, control communications, and signals transmitted along a coaxial wire. In a preferred embodiment, these electrical conductors are all disposed on a single ribbon cable. Each module within the integrated outlet can attach to only certain conductors to increase safety in the resulting system.
