  • Publication number: 20180175946
    Abstract: System and method for array antenna failure detection and antenna self-correction are introduced. In the array antenna failure detection and antenna self-correction system, a signal analyzer is employed to perform gain analysis so as to perform gain attenuation/compensation, and a DC offset generator is employed to generate a set of known offset amounts which are added to signals, so that, at the receiving end, a phase offset amount can be derived based on comparisons with the original signal, and antenna correction can then be performed accordingly. In this way, computational complexity of the system can be reduced, and the speed of antenna correction can be increased.

  • Publication number: 20140163716
    Abstract: A bridge device for manufacturing a storage device, including a first transmission interface, a second transmission interface, a mode select unit, a power control unit, and a bridge controller is provided. The mode select unit generates a mode select signal responsive to a manufacturing process command. The power control unit controls powering operation of the storage device. The bridge controller receives the manufacturing process command through the first transmission interface. When the bridge controller detects the presence of the storage device, drives the power control unit turning off the storage device. After a first predetermined period, the bridge controller drives the mode select unit transmitting the mode select signal to the storage device through unused pin of the second transmission interface. The bridge controller drives the power control unit turning on the storage device after a second predetermined period to have the storage device entering a predefined mode.
