\brief type definition for a sync object container
Sync object is object used to synchronize between two threads or thread and interrupt handler.
One thread is waiting on the object and the other thread send a signal, which then
release the waiting thread.
The signal must be able to be sent from interrupt context.
This object is generally implemented by binary semaphore or events.
