ZOZ objects can be made of ZOZ objects - page 4 When I look at a refrigerator, I see a thousand ZOZ objects. It contains several major subsystems: a cooling system, an ice maker system, an airflow system, a lighting system, a separate freezer with its own systems, and so on. And each of these are separate ZOZ objects. The cooling system might contain a pump and several valves and sensors. And each of these are ZOZ objects. And its pump might contain a motor, which in turn contains coils and sensors. And each coil contains a power controller and a few sensors of its own. And the power controllers contain ..., and so on and so on. And every single one of these things is an independent ZOZ object. A valve just a half-inch across might be comprised of dozens of smaller ZOZ objects, each with their own still smaller sub- and sub-sub-objects. The valve might contain a small motor, which contains sensors and coils. There might be a pair of flow-rate sensors in the input and output streams, to ensure its own proper operation. It might contain a power harvesting module which draws power from the flow of the fluid itself. Thus, there could be a hundred ZOZ objects just inside this tiny half-inch valve. The lighting system has a few lights and a door-open sensor. And a separate light sensor for each light to provide feedback that the light is working. And every one of the above mentioned objects, perhaps thousands of them in total, is a ZOZ object, linked into the ZOZ data stream.
