20110271703 | REFRIGERATOR - A refrigerator is provided. The refrigerator includes a compressor, a condenser, an expansion valve, an evaporator, a bypass pipe, and a valve device. The condenser condenses refrigerant discharged from the compressor, and the expansion valve expands the refrigerant condensed in the condenser. The evaporator evaporates the refrigerant expanded in the expansion valve, and the bypass pipe allows the refrigerant discharged from the compressor to move toward an inlet of the evaporator. The valve device allows the refrigerant discharged from the compressor to selectively move toward the bypass pipe or the condenser. The valve device comprises an inlet, a first outlet, and a second outlet. The refrigerant discharged from the compressor flows into the inlet. The refrigerant is discharged toward the condenser through the first outlet, and is discharged toward the bypass pipe through the second outlet. The first outlet has a diameter larger than that of the second outlet. | 11-10-2011 |

20100325435 | Two-factor authenticated key exchange method and authentication method using the same, and recording medium storing program including the same - A two-factor authenticated key exchange method. A subscriber station transmits a value generated by using an identifier and an authentication server's public key to the authentication server through an access point. The authentication server uses the value to detect the subscriber's password, a key stored in a token, and the authentication server's secret key, generate a random number. The subscriber station uses the random number, password, and the key to transmit an encrypted value and the subscriber's authenticator to the authentication server. The authentication server establishes a second value generated by using the password, key, and random number to be a decrypted key to decrypt the encrypted value, authenticate the subscriber's authenticator, and transmits the authentication server's authenticator to the subscriber station. The subscriber station authenticates the authentication server's authenticator by using the key and password. | 12-23-2010 |
