Abstract: An electrical network architecture including a reconfigurable interface layer, along with a corresponding reconfiguration methodology. The interface layer is comprised of reconfigurable interface devices which allow a plurality of sensors and actuators to communicate with a plurality of control units. Each sensor or actuator is connected to multiple interface devices, which in turn are connected to a bus. The control units are also connected to the bus. In the event of an interface device failure, other interface devices can be reconfigured to maintain communication between sensors, actuators and control units. In the event of a control unit failure, the interface devices can be reconfigured to route sensor and actuator message traffic to a different control unit which can handle the functions of the failed control unit. The overall number of control units can also be reduced, as each control unit has flexible access to many sensors and actuators.

Abstract: A system and method for compartmentalizing memory sections in a controller to allow compartments to be individually reprogrammed without affecting files in other compartments. The method includes defining a main memory in the controller that stores a plurality of different types of content files that each include lines of code, where the main memory includes compartments having memory slots for lines of code that have been programmed and empty memory slots where lines of codes can be written into. The main memory is initially programmed to store desired content files in the memory compartments. Subsequently, if it is determined that code stored in the main memory needs to be reprogrammed, the reprogramming is performed to flash only the memory compartments that include the code that needs to be reprogrammed and those memory compartments that include code that is linked to the code that needs to be reprogrammed.
