  • Patent number: 11016547
    Abstract: An electronic display has a display panel with a display surface visible through a housing. A processor controls functions of the display and operating conditions within the housing. Input sensors are disposed within the housing and sense operating conditions within the housing. Output components respond to control signals. Modules have a unique address identifier and a connection to one of the input sensors and output components. A CAN bus communicates between the modules and electronic processor. Processing of signals received from the input sensors and control signals is distributed amongst microcontrollers on the modules. The processor uses a unique address identifier to receive a temperature reading from a module connected to a temperature sensor; process the temperature reading to determine one or more new fan speed setting; and send data via the bus to a module to a fan speed to the new setting.
