摘要:
A radio frequency identification tag includes an antenna terminal, a memory, a D/A converter, a clock extractor, a frequency synthesizer, a radio frequency UP converter, and a power unit. An energy pumping signal is received and tag identification information is transmitted through the antenna terminal. The tag identification information is stored in the memory. The D/A converter converts the tag identification information into an analog signal in response to an information request signal included in the energy pumping signal. The clock extractor extracts a clock signal from the energy pumping signal. The frequency synthesizer is operated according to the clock signal of the clock extractor, and generates a frequency. The radio frequency up converter up-converts a signal output from the D/A converter, and allows the up-converted signal to be transmitted through the antenna terminal. The power unit supplies internal power.

The present invention is related to a reinforcing member for a membrane for improving the pressure-withstanding property of the membrane having corrugations, and a membrane assembly having the reinforcing member and a method of constructing the membrane assembly. By providing a reinforcing member for a membrane having corrugations and installed in an insulating structural member of an LNG cargo, the present invention can prevent the collapse of the corrugation and attenuate shocks against a same load without increasing the facial rigidity of the corrugation, and improve the insulating property by forming an additional insulating layer.
