Disclosed is a flexible thermoelectric system. More particularly, the flexible thermoelectric system includes thermoelectric units that are wearable on the human body; a heating unit that is provided on one side of the thermoelectric units so as to be disposed between the thermoelectric units and the skin and is formed of a hygroscopic and exothermic material; and a heat dissipating unit that is provided on other side of the thermoelectric units such that the heat dissipating unit faces the heating unit and the thermoelectric units are disposed between the heat dissipating unit and the heating unit; wherein the heating unit and the heat dissipating unit are flexible. Due to such a configuration, the flexible thermoelectric system may be flexibly attached to the skin and temperature difference between upper and lower surfaces of the thermoelectric units may be maximized. Accordingly, power generation or cooling performance may be improved.

Flexible thermoelectric system

Disclosed is a thermoelement including a body including a plurality of joint portions, at least two of the plurality of joint portions being rotatably connected to each other, a shaft provided to the body and configured to provide a center of rotation of the plurality of joint portions, and a thermoelectric material provided between the plurality of joint portions.

Thermoelement and a wearable device comprising the same

Provided is a method of manufacturing a Pb&#x2014;Te based thermoelectric material, the method comprising: forming a Pb&#x2014;Te based by mixture mixing element lead, element tellurium and a dopant; melting and then quenching the mixture; and obtaining a thermoelectric sintered body by hot-pressing a molded body obtained after the quenching.

Method of manufacturing thermoelectric material and thermoelectric material prepared by the method and thermoelectric generator

An apparatus and method for spatially predicting image data, an apparatus and method for encoding image data, an apparatus and method for compensating for spatial prediction of image data, and an apparatus and method for decoding image data. The spatial prediction apparatus of image data includes: a spatial prediction unit performing a spatial prediction of pixel values of a current block using pixel values of blocks adjacent to an upper row of the current block. A pipeline process is possible when the spatial prediction is performed, thereby performing real time encoding and decoding.

Apparatus and method for spatially predicting, encoding, compensating and decoding image data

There are provided an apparatus and method for performing dynamic capacitance compensation (DCC) in a liquid crystal display (LCD). The DCC apparatus includes: a first line buffer reading and temporarily storing pixel values of an image for each line; an encoder transforming and quantizing the pixel values stored for each line for each block and generating bit streams; a memory storing the generated bit streams; a decoder decoding the bit streams stored in the memory for the each block and outputting the decoded bit streams; a second line buffer reading and temporarily storing the decoded pixel values for the each block; and a compensation pixel value detector detecting a compensation pixel value for each pixel, from pixel value differences between pixel values of a current frame stored in the first line buffer and pixel values of a previous frame stored in the second line buffer. Therefore, it is possible to reduce the number of pins of a memory interface by reducing the number of memory device for storing pixel values of image data, required for performing DCC of a LCD, resulting in minimizing a chip size, and to enhance compression efficiency without visual deterioration in images.
