  • Patent number: 10912005
    Abstract: The mobile communication device supports a plurality of RATs and includes a first wireless transceiver, a second wireless transceiver, and a controller. The first wireless transceiver performs wireless transmission and reception to and from a first cellular network utilizing a first RAT. The second wireless transceiver obtains a non-cellular signal indicator. The controller determines whether the first RAT is a predetermined one of the plurality of RATs when the mobile communication device camps on the first cellular network, and if not, predicts whether there is a second cellular network available, which utilizes the predetermined RAT, based on the non-cellular signal indicator. In response to predicting that the second cellular network is available based on the non-cellular signal indicator, the controller further enables the mobile communication device to camp on the second cellular network via the first wireless transceiver.

  • Patent number: 10826101
    Abstract: A flow battery apparatus is provided with shunted currents repressed. The apparatus has a positive electrode device, a negative electrode device and a plurality of gas-gap devices. Gas-gap devices are separately set between branching channels and inlet and outlet manifolds of positive and negative electrodes. Each of the branching channels separately has an inserting tube to be inserted into one of the gas-gap devices. The diameter of the inserted vessel of gas-gap devices is bigger than the diameter of the inserting tube connected to a corresponding one of the branching channels. Thus, working liquids transferred to the positive and negative electrodes are segregated with coordination of the gas-gap devices. Only air spaces and discrete liquid drops are left between separated parts of the working liquids. Thus, shunted currents are repressed by preventing conductive paths from being formed between the positive and negative electrodes.
