    I will do a couple. You need to do your own thinking.

    1)public address system
    input:voice message
    process: amplification, and distribution to speakers
    output: loud message at selected sites.

    7) refrigerator: Input: temperature sensor
    Process: When internal temp is above preset temp, turn on refergerator compressor
    Output: Cold box with temp below a preset.

    10) auto night light.
    Input: light sensor sensiing light
    Process: if ambient light is below threshold, turn on light.
    Output: light on or off
