PROBLEM TO BE SOLVED: To provide a switching system for switching variable-length data of a heterogeneous network which is applicable to a home gateway for a home network environment and a home network service. SOLUTION: The switching system includes at least two switching interface modules connected to at least two networks respectively to transmit and receive packets; a switching chip for receiving the packets from a first switching interface module and for switching the received packets to a second switching interface module; a SERDES channel for transmitting the packets between the switching interface module and the switching chip; and a signaling channel for transmitting a port number between the switching interface module and the switching chip.

PROBLEM TO BE SOLVED: To provide an integrated optical modulator which can minimize an influence of chromatic dispersion and has a more simplified configuration by connecting a carrier wave band modulator using a double sideband modulation method and an intermediate frequency band modulator using a single sideband modulation method in series, and to provide a method for manufacturing the integrated optical modulator. SOLUTION: The integrated optical modulator comprises the carrier wave band modulator using the double sideband modulation method and the intermediate frequency band modulator using the single sideband modulation method. The carrier wave band modulator and the intermediate frequency band modulator are connected in series. COPYRIGHT: (C)2007,JPO&INPIT
Abstract:
PROBLEM TO BE SOLVED: To provide a patterning apparatus for forming a pattern in a relatively large area on a substrate and to provide a method for patterning using the apparatus. SOLUTION: A flexible substrate coated with a photosensitive agent is continuously supplied from a supply section to a guide section. The light emitting from a light source is allowed to radiate on a cross section of the substrate. A mask is disposed between the substrate and the light source so that the beam emitting from the light source selectively exposes the cross section of the substrate. COPYRIGHT: (C)2005,JPO&NCIPI

PROBLEM TO BE SOLVED: To provide a wireless system for use in management of underground facility, more specifically, a wireless communication system for management of underground facility that can measure the status information of a facility buried in the ground, i.e., a harsh wireless communication environment, accurately and can provide the accurate status information.SOLUTION: The wireless communication system for management of underground facility includes a large number of sensor nodes that are attached to an underground facility, sense the status information of the underground facility by a drive signal including a wake up signal being transmitted and output a sense signal by magnetic field communication, and an information collector which outputs a drive signal at the sensor node, collects the sense signals transmitted from the sensor nodes, and transmits the sense signals thus collected to a monitoring system by short-range wireless communication.
Abstract:
PROBLEM TO BE SOLVED: To provide an anode material for a lithium secondary battery having high discharge capacity, excellent cycle characteristic and high charge discharge efficiency, to provide a method for manufacturing the anode material, and to provide a lithium secondary battery including the material.SOLUTION: A positive active material for the lithium secondary battery is composed of a lithium manganese phosphate based compound including one metal element selected among Mg, Ti, Ni, Co, and Fe and having phosphorus a part of which is substituted with arsenic. The positive active material is manufactured by reacting a lithium oxide, a manganese oxide, a phosphorus oxide, a chelate agent, and water in a hydrothermal reactor, and adding a substitution product of the above elements and arsenic substitution to react together.
Abstract:
PROBLEM TO BE SOLVED: To provide a magnetic field communication method for low-power node management which improves the communication performance and efficiency of a radio network of a magnetic field communication low-requency band.SOLUTION: Though the magnetic field communication method for low-power node management is performed in a radio network of a low-frequency band that is comprised of one MFAN-C and at least one MFAN-N, a physical layer frame is comprised of a preamble, a header, and a payload, and the preamble is comprised of a wake-up bit string and a synchronization bit string. The wake-up bit string is desirably added to only the preamble of the frame that is transmitted from the MFAN-C when the MFAN-N is activated from a power saving mode. The wake-up bit string is desirably modulated using an ASK system, and the synchronization bit string is desirably modulated using a BPSK system.
Abstract:
The present invention relates to a method or an operation for providing a personalized TV-Anytime metadata service. According to an embodiment of the present invention, there is provided a method of deleting user metadata managed by a TV-Anytime metadata server using a SOAP operation, comprising the steps of a) providing an element type of a SOAP delete operation, the element of the SOAP delete operation including at least a first sub-element for designating user identifier information, b) receiving the element of the SOAP delete operation, in which the user identifier information is designated, from a client of a user, and c) identifying the user on the basis of the user identifier information in the received element of the SOAP delete operation and deleting user metadata about the identified user.
