Abstract:
A humanoid robot fall controller controls motion of a robot to minimize damage when it determines that a fall is unavoidable. The robot controller detects a state of the robot during the fall and determines a desired rotational velocity that will allow the robot to re-orient itself during the fall to land on a predetermined target body segment (e.g., a backpack). The predetermined target body segment can be specially designed to absorb the impact of the fall and protect important components of the robot.
Abstract:
A method of forming a pattern and a manufacturing method of a liquid crystal display includes forming the pattern with a thin thickness by coating a pattern material on a printing roll using a nozzle, removing a surplus portion of the pattern material from the printing roll by using a plate, and transferring the pattern material remaining on the printing roll to a substrate to form the pattern.
Abstract:

Abstract:
A motion compensation apparatus to provide block-based motion compensation, and a method thereof. A first motion compensation interpolator calculates a first interpolation pixel by reading a first and a second pixel corresponding to a motion vector of an estimated current block respectively from a current and a previous frame or field. A second motion compensation interpolator calculates a second interpolation pixel by reading a third and a fourth pixel corresponding to a motion vector of peripheral blocks adjacent to the current block respectively from the inputted current and previous frame or field. A candidate interpolation pixel calculator calculates a candidate interpolation pixel by allocating a predetermined weight to the first and the second interpolation pixels, among the current blocks. A motion analyzer analyzes the motion vectors of the current block and the peripheral blocks, and determines discontinuities between the blocks. A final interpolation pixel selector selects either of the first interpolation pixel and the candidate interpolation pixel as a final interpolation pixel, according to the discontinuities determined at the motion analyzer. Accordingly, by applying an overlap block motion compensation according to discontinuities between the current and the peripheral blocks, an image can be provided in which the block artifacts are removed or reduced.

A service provider discovery method in a wireless network environment, includes receiving, by the gateway, a service request (SREQ) packet which is broadcast from a first mobile node in the ad-hoc network; updating and transmitting, by the gateway, the SREQ packet to a service repository which stores at least one service provider information, in the infrastructure network; transmitting, by the service repository, a service reply (SREP) packet containing information relating to a service provider which provides a service requested by the SREQ packet to the gateway, and updating and transmitting, by the gateway, the SREP packet to the first mobile node. Accordingly, the service can be used in association with the ad-hoc network and the infrastructure network.
Abstract:
The present invention relates to the IL-12p40 subunit mutant gene which can produce IL-12 (interleukin 12) of human and mouse origin with high activity, the expression vector including above mutant gene and the use of them to DNA vaccine adjuvant. Particularly, it relates to IL-12p40 mutant gene which inhibits the secretion of IL-12p40 but normally secretes active IL- 12p70 by making mutation at Asn-222 (human) or Asn- 220 (mouse) amino acid of IL-12p40, which acts as a competitive inhibitor of active form of IL-12, IL-12p70. Therefore, the IL-12p40 mutant gene of the present invention can be useful for DNA vaccination and gene therapy against various diseases, for example, AIDS, hepatitis C or hepatitis B, cancer, influenza, tuberculosis and malaria, which essentially require cellular immune responses for their therapy.
Abstract:
A touch panel and an electronic device are provided. The touch panel includes a first substrate; a second substrate that is spaced apart from the first substrate by a gap and includes a contact surface; driving electrodes that are formed on each of the first substrate and the second substrate; and electro-rheological fluid that is disposed in the gap. When a driving voltage is applied between the driving electrodes, a button area is delimited due to a variation in viscosity of the electro-rheological fluid at the button area. When a thickness of the gap is reduced to a value equal to or less than a threshold due to a pressing force applied to the contact surface at the button area, the driving voltage is cut off.
Abstract:
A method for effectively using power resource in a wireless mesh network is disclosed to select and change a level of a power saving mode according to terminal and network situations to increase the duration of the network's existence as well as improve the power consumption of each mesh terminal. After active mesh terminals that are to perform a data relay function and super-saving mesh terminals that are not to perform the data relay function are selected in consideration of a network topology at certain periods, the level of a power saving mode of the mesh terminals selected as the super-saving mesh terminals is higher than that of the mesh terminals selected as the active mesh terminals. And then, a routing path in a tree form is formed along the mesh terminals selected as the active mesh terminals to transmit data.

A driving system is provided. The driving system includes a fixed substrate, a coil unit which generates an electromagnetic force if an electric current applied, a magnet unit formed on the fixed substrate to face the coil unit, and a plurality of driving units which are interconnected with each other on the fixed substrate, and which are moved respectively in parallel direction with respect to a surface of the fixed substrate in accordance with an interaction between the electromagnetic force and a magnetic force of the magnet unit, if the electric current is applied. As a result, a non-contact driving is provided.
Abstract:
Disclosed is an apparatus and method for compensating for estimated motion vectors by deciding whether a pattern image exists in target blocks for motion estimation. A motion estimation part compares a current block of a current frame/field to a search area established in a previous frame/field, calculates plural motion estimation error values, and estimates a temporary motion vector of the current block based on the plural motion estimation error values. A pattern decision part analyzes the calculated motion estimation error values, and decides that the current block is a pattern image. A motion compensation part produces a compensation motion vector of the current block by use of the plural motion estimation error values if the current block is decided as the pattern image. A motion vector selection part selects a final motion vector based on a result of the pattern decision part.
