Abstract: A cooling structure includes a housing having a cooling channel defined therein through which a coolant flows and includes a sealing cap fitted to a hole of the housing to seal the hole. The sealing cap includes a blocking member configured to be in contact with an internal surface of the housing. The cooling structure may be for cooling a motor, such as an in-wheel vehicle motor.

Abstract: A channel structure includes a cooling channel continuously formed inside a housing. A coolant is configured to flow in the cooling channel. The cooling channel includes a plurality of channel portions spaced apart from each other and extending in the housing by changing directions.

Abstract: The present disclosure provides a sealing device and an in-wheel motor including the sealing device. The in-wheel motor includes a stator, a rotor rotatably disposed with respect to the stator, an annular inner seal connected to the stator and spaced apart from the rotor by a predetermined gap so as to be disposed between the stator and the rotor, and an annular slinger coupled to an end portion of the rotor, wherein the annular inner seal seals between the slinger and the in-wheel motor.

Abstract: The present invention relates to an image encoding and decoding technique, and more particularly, to an image encoder and decoder using unidirectional prediction. The image encoder includes a dividing unit to divide a macro block into a plurality of sub-blocks, a unidirectional application determining unit to determine whether an identical prediction mode is applied to each of the plurality of sub-blocks, and a prediction mode determining unit to determine a prediction mode with respect to each of the plurality of sub-blocks based on a determined result of the unidirectional application determining unit.

Abstract: The present invention relates to an apparatus and method for encoding and decoding an image by skip encoding. The image-encoding method by skip encoding, which performs intra-prediction, comprises: performing a filtering operation on the signal which is reconstructed prior to an encoding object signal in an encoding object image; using the filtered reconstructed signal to generate a prediction signal for the encoding object signal; setting the generated prediction signal as a reconstruction signal for the encoding object signal; and not encoding the residual signal which can be generated on the basis of the difference between the encoding object signal and the prediction signal, thereby performing skip encoding on the encoding object signal.

Abstract: In a radio resources management method for a Wireless Local Loop (WLL) system, the compatibility of a radio environment can be judged by setting and storing information of a home base station, of a WLL subscriber terminal, and comparing the stored information with information of a base station currently relaying communications with the WLL subscriber terminal. Compatibility of the radio environment can also be judged by comparing the reception time intervals of a power ON/OFF message, position registration request message, or call processing request message with a reference time, at certain audit cycles.
