Disclosed is a conductive polymer which is easily dispersed in an organic solvent. A method of preparing the conductive polymer adapted to be dispersed in an organic solvent is also provided, which includes chemically polymerizing a monomer using as a dopant anion a phosphate-based compound having solubility in an organic solvent. The conductive polymer capable of being dispersed in various organic solvents can be obtained through a simple preparation process, and thus can be utilized in the fields of applied materials in which the use of conventional water-dispersible conductive polymers is limited.

A radiator fin of a heat sink has a shape of a portion of a circle with a small radius which is not overlapped with a circle with a large radius when two circles with different radiuses are overlapped with each other such that centers of the two circles are in a single circle, as a cross sectional shape. An arrangement of radiator fins of a heat sink on a radiator plate, includes at least two radiator fins provides to at least one radiator plate such that centers of inner and outer arcs of circles forming the radiator fins are on a reference line, and an outer arc of one of two adjacent radiator fins moves within a track of an inner arc of the other radiator fin or an inner arc of one radiator fin moves out of a track of an outer arc of the other radiator fin.

The present invention relates to a compound which can be used as a material for a hole injection layer or a hole transporting layer of organic light emitting diodes (OLEDs) or electroluminescent elements. The compound is synthesized into a conductive polymer using liquid polymer ions, and this conductive polymer can be used as a material for a hole injection layer or a hole transporting layer of an organic light emitting diode. The compound is advantageous in that a hole injection layer formed using the compound has more excellent performance and can be maintained over a longer lifespan than a hole injection layer formed using conventional compounds.

Disclosed is a method for controlling a wiper blade with heating elements embedded therein and coupled to a wiper arm of a vehicle to wipe a glass surface while moving together with the wiper arm. The method includes: detecting the operation or not of an engine of a vehicle; detecting the external temperature outside of the vehicle; and automatically supplying power to the heating elements based on the detected information on the operation of the engine and the temperature information. A wiper blade with heating elements capable of optimally maintaining a condition of the wiper blade even when the external temperature is low is also provided.

A base station for use in a wireless network that communicates with mobile stations according to the IEEE 802.16m standard. The base station transmits unicast data and E-MBS data in the downlink to mobile stations using physical resource units (PRUs) that are partitioned into a plurality of frequency partitions. The base station transmits E-MBS data using a first set of PRUs in at least a first common frequency partition, wherein the first set of PRUs are also used by at least a second base station to transmit E-MBS data. The base station further transmits unicast data using a second set of PRUs, wherein the second set of PRUs are randomized with respect to PRUs used by the at least a second base station to transmit unicast data.

An autofocusing optical system of a camera module which can be installed in a subminiature camera module. In the optical system, a first lens group has an overall positive refractive power. A second lens group has an overall negative refractive power. The second lens group includes a liquid lens having a meniscus formed between non-miscible first and second liquids, the first liquid having conductivity and polarity, the meniscus having a curvature radius changing in response to a voltage applied to serve as a refractive surface, thereby autofocusing the optical system, a first cover lens for sealing the liquid lens at an object side and a second cover lens for sealing the liquid lens at an image side. A third lens group has an overall positive refractive power. Also, a fourth lens group has an overall negative refractive power.

For use in a wireless communication network, a subscriber station is capable of switching carriers. The subscriber station is configured to receive an N-bit bitmap from the communication network and determine at least one unicast available interval based on an arrangement of the N bits in the N-bit bitmap. The subscriber station is also configured to switch from a first carrier to a second carrier at a start of the at least one unicast available interval.
