An authentication method includes projecting a near infrared (NIR) ray using a light emitting diode (LED) of a terminal, receiving a light reflected by a vein of a user using an image sensor of the terminal, verifying whether an image generated using the received light exhibits a vein pattern, in response to the image generated using the received light being verified as exhibiting the vein pattern, generating a vein pattern of the vein based on an image generated using the received light, and in response to the generated vein pattern being determined to match a pre-stored vein pattern, authenticating the user as a registered user corresponding to the pre-stored vein pattern.

Method and apparatus with vein pattern authentication

A method and apparatus for authenticating a user using a vein pattern are provided that project a near infrared (NIR) ray toward a skin of the user using a light emitting diode (LED), where the user is adjacent to a terminal including the LED. An image sensor receives a light reflected by the skin, generates a vein pattern of the skin based on an image generated using the received light, and authenticates the user as a registered user of a pre-stored vein pattern when the generated vein pattern matches the pre-stored vein pattern.

A photoalignment material includes an alignment polymer, a photoalignment additive including a compound represented by the following Chemical Formula 1 and an organic solvent.  In Chemical Formula 1, Rrepresents a cyclic compound. A and B independently represent a single bond or &#x2014;(CH)&#x2014;. 'n' represents an integer in a range of 1 to 12. Each &#x2014;CH&#x2014; of A and/or B may be replaced with Rrepresents an alkyl group having 1 to 12 carbon atoms, and each &#x2014;CH&#x2014; of A and/or B may be replaced with &#x2014;O&#x2014;. Rrepresents In Chemical Formula 1, each hydrogen atom excluding hydrogen atoms of Rmay be replaced with chlorine (Cl) or fluorine (F).

A storage system includes a storage medium configured to store data and a buffer memory configured to buffer data to be written to the storage medium. The storage system further includes a controller configured to selectively transfer the buffered data to the storage medium responsive to an invalidity indicator received from an external source. For example, the invalidity indicator may comprise unwrite information received from an external source, e.g., information that indicates that selected buffered data corresponds to deleted file data.

Apparatus and methods using invalidity indicators for buffered memory

Disclosed is a system providing a VPN service by connecting a VPN (virtual Private Network) to a mobile communication network. A home agent (HA) stores location information of a mobile node (MN) and information on whether the MN is registered in the VPN. A foreign agent (FA) transmits a location registration request message to the HA by receiving location registration information of the MN, and transmits data to an ISP (Internet Service Provider) router in the same subnet upon receiving a VPN service request. A server provides the VPN service and a router network connects the VPN to the FA. The router network includes a server for searching an edge IP router in the network using an address of the FA. The HA prevents an MN from accepting a call request received from a specific node in an IP network while the MN is performing a VPN service.

Memory interface systems include one or more channel lines that couple a memory to a memory controller such that the channel line(s) are responsive to a terminal voltage that is independent of supply voltages for the memory and the memory controller. Because the memory interface system uses a terminal voltage that is independent of the supply voltages of the memory and the memory controller, the interface system may be unaffected by voltage differences between the memory supply voltage and the memory controller supply voltage.

A system and method of charging for user traffic without including signaling costs in a wireless communication system is provided. In a system and method of charging a user equipment (UE) in a gateway node in a mobile communication system having a serving support node within a radio network connected to the UE and the gateway node for connecting the radio network to a home server in an external network, the gateway node acquires from the external network the address of a home server that provides a service requested by the UE, stores the home server address, clears charging information collected with respect to signaling generated prior to the allocation of the home server address, and re-collects charging information about the service that the UE receives.

An integrated circuit memory system includes one or more memory modules in which at least one of the memory modules is responsive to a control signal and has delay control information stored thereon. The memory system further includes a memory controller that is configured to generate the control signal in response to the delay control information.

A method for transmitting a data packet from a mobile node to a correspondent node through a foreign agent while maintaining security is disclosed. A correspondent node transmits a first data packet for communication with a mobile node to the home agent. Upon receipt of the first data packet from the home agent, the foreign agent transmits the first data packet to the mobile node through a radio channel. The home agent transmits the IP address of the foreign agent to the correspondent node after transmitting the first data packet to the foreign agent. The correspondent node transmits tunneling indication information indicating whether it can decapsulate a data packet encapsulated by the foreign agent to the foreign agent after receiving the IP address of the foreign agent from the home agent. The foreign agent encapsulates subsequent data packets received from the mobile node with a tunneling IP header for reverse tunneling and transmits the encapsulated data packets to the correspondent node, after receiving the tunneling indication information from the correspondent node.

Packet transmission method for mobile internet

There is provided a handover method for a mobile node (MN) having a mobile IP (Internet Protocol) address in a mobile communication system. When a handover occurs as the MN moves from the area of a first FA to the area of a second FA adjacent to the first FA, the second FA transmits a Binding Update message including the IP address of the second FA and an acknowledgement request to the first FA. In response to the Binding Update message, the first FA transmits a Binding Acknowledge message to the second FA, including a field indicative of the IP tunneling capability of a router connected to a corresponding node (CN) to which the MN connects a call.

A semiconductor memory device and a system using the semiconductor memory device can perform a data sampling operation safely without a phase synchronization device such as delay locked loop (DLL) or phase locked loop (PLL), wherein the semiconductor memory device incorporates a strobe signal, which is synchronized with a data signal, both traversing similar-length paths between a memory device and a memory controller. In a read operation, the semiconductor memory device generates a first strobe signal synchronized with a read data signal, whereby a read data signal is outputted at both a rising and a falling edge of a strobe signal. In a write operation, a second strobe signal is generated whereby only a single edge is used to generate a write data signal, thereby allowing sufficient time for a data sampling operation to occur and thus operating at half the speed of a read operation.
