| 20120102563 | METHOD AND APPARATUS FOR CONTROLLING LOADS OF A PACKET INSPECTION APPARATUS - The present invention periodically monitors the amount of packets flowing into a packet inspection apparatus, i.e., a load level, and compares the load level with a predetermined upper or lower limit value. Accordingly, the present invention blocks some of the packets or passes along some of the packets through the packet inspection apparatus when the load level exceeds a certain level, and thus the load controlling method and apparatus guarantees continuous operation of the packet inspection apparatus even in an overloaded state. In addition, the load controlling method and apparatus according to the present invention effectively selects packets to be blocked or passed without departing from the original functions of the packet inspection apparatus. The load controlling method and apparatus is configured simply so as not to additionally induce a load in the process of selection, and the load controlling apparatus selectively operates only in an overloaded state. | 04-26-2012 |

| 20110213976 | METHOD FOR DOWNLOADING CONDITIONAL ACCESS SYSTEM FOR DIGITAL BROADCASTING - The present invention relates to a method of downloading a conditional access system (CAS) for digital broadcasting in a digital broadcasting system. More specifically, the present invention includes a transmitter which includes a DCAS authentication proxy (AP), a personalization server, a DCAS provisioning server, and a head-end, and a set-top box as a receiver, which includes a DCAS host. In particular, a mutual authentication occurs between the DCAS AP and the DCAS host and key distribution, between the personalization server and the DCAS host and key distribution, and between the DCAS provisioning server and the DCAS host and key distribution in order to protecting a conditional access system that descrambles scrambled broadcasting contents when broadcasting contents are downloaded from an IP-TV broadcasting system and viewed. | 09-01-2011 |
| 20110182115 | METHOD FOR FABRICATING INDIUM (In)-ANTIMONY (Sb)-TELLURIUM (Te) NANOWIRES AND PHASE-CHANGE MEMORY DEVICE COMPRISING THE NANOWIRES - Disclosed herein is a method for manufacturing (In)—(Sb)—(Te) (IST) nanowires and a phase-change memory device comprising the nanowires. The method comprises providing a substrate and vapors of In, Sb and Te precursors in a chamber and allowing the vapors to react with each other on the substrate in the chamber at a temperature of 230-300° C. and a pressure of 7-15 Torr. With the method, IST nanowires can be fabricated cost-effectively. | 07-28-2011 |
| 20110175605 | Magnetic Sensor - Provided is a magnetic sensor for detecting a magnetic field. The magnetic sensor includes a magnetic layer of a closed loop shape; a pair of current terminals which face each other contacting with the closed loop and through which current is input/output; and a pair of voltage terminals which face each other contacting with the closed loop and from which output voltage is detected. Both an anisotropic magnetoresistance effect (AME) and a planar Hall effect (PHE) contribute to the output voltage and a hysteresis of the output voltage is eliminated by exchange coupling of a ferromagnetic layer by a ferromagnetic-antiferromagnetic layer structure and a ferromagnetic-metal-antiferromagnetic layer structure. Accordingly, it is possible to minimize a hysteresis due to a demagnetization factor of the closed loop, stabilize the output voltage of the magnetic sensor and enhance sensitivity. | 07-21-2011 |

| 20110085522 | METHOD FOR ALLOCATING SLOTS FOR EMERGENCY DATA AND METHOD FOR TRANSMITTING EMERGENCY DATA USING THE SAME - There are provided a method for allocating slots for emergency data and a method for transmitting emergency data using the same. The method for allocating slots for emergency data may be configured to include: allocating slots for emergency data to superframes that are configured to include a beacon period indicating a start of the superframe, a contention access period (CAP) transmitting data through contention, and a contention free period (CFP) transmitting data without contention; and providing slot allocating information on the emergency data to nodes. As a result, the method for allocating slots for emergency data allocates the separate slots for the emergency data while avoiding the contention access period (CAP) frequently used, which are used in the inter-node contention mode to enable the plurality of nodes to use one slot for one emergency data. In particular, even though there may be the risk of transmission failure due to the contention mode, the occurrence frequency of the emergency message, or the like, is low, which results in a similar effect to allocating the dedicated slots for the emergency data to the plurality of nodes while avoiding the transmission failure. | 04-14-2011 |
| 20100187705 | PREPARATION METHOD FOR MICRO-CAPSULE USING A MICROFLUIDIC CHIP SYSTEM - A method for preparing microcapsules using a droplet-based microfluidic chip.

The method involves the use of a simple microfluidic channel and selectively photopolymerizing the shell of the droplets without needing the use of a chemically treated microfluidic channel or a complex microfluidic channel. | 07-29-2010 |
