  • Patent number: 7664561
    Abstract: A new Task Queue Methodology (TQM) is provided for reducing traffic jams and for controlling transportation priority in an Automatic Material Handling System (AMHS). A Stocker Resource Q, under control of TQM, maintains records of stockers that are under control of the AMHS and the availability thereof. For available stockers, a Task-Q under control of a Queue Manager (TQM) is accessed, extracting therefrom records that match available stocker resources. For the available stocker resources, the tasks that are scheduled against these resources are sorted by priority and by longest wait time, resulting in one selected task. For the in this manner selected task, a Move command is issued by the TQM to the Automatic Material Handling System.

  • Publication number: 20100014491
    Abstract: A method and system is provided to reinforce wireless communication capabilities between multiple network nodes of an wireless network group. The method and system first detects a wireless transmission capability between a first network node and a second network node. When the wireless transmission capability is lower than a threshold value, one set of reinforcing coordinates will be derived by introducing the first geographic information and the second geographic information. Afterwards, move a third network node to a position with the set of reinforcing coordinates to establish an alternative wireless transmission route between the first network note and second network node. Therefore, when an original wireless transmission route between any two network nodes is abnormal, the alternative wireless transmission route will be available in time and reduce the risks of losing transmission signals.
