  • Patent number: 9863833
    Abstract: A leak sensor includes a base layer which is formed by soaking a plate-shaped structure into a resin solution, particularly a fluorine-based resin solution, or formed of a plate-shaped structure of a resin, particularly a fluorine-based resin; and a sensor layer in which a leak detection part having a predetermined area is formed by coating or printing a mixture of a liquid resin or a liquid fluorine-based resin and a conductive material on the base layer in a predetermined pattern, wherein the leak detection part of the sensor layer is formed on a side surface of the sensor layer to be exposed to the outside. Therefore, even though the sensor is not located just under the leaked fluid, the sensor becomes in contact with the fluid, and thus can detect the fluid leakage.

  • Patent number: 9326124
    Abstract: A method of informing a selected CN operator from a UE to a RAN in an NS system where a plurality of CN operators shares the RAN is provided. Upon request of transmission of an IDT, the UE acquires a CN operator ID selected from a multi-ID list broadcasted from a cell in which an RRC connection has been established, and transmits an IDT message with the selected CN operator ID to the RAN. Upon receipt of the IDT message, the RAN determines whether the IDT message includes a selected CN operator ID. In the presence of the selected CN operator ID, the RAN stores the selected CN operator ID in a UE context. In the absence of the selected CN operator ID, the RAN reads a stored selected CN operator ID from the UE context. The RAN then selects a CN operator using the selected CN operator ID.
