Abstract: Disclosed is an NFC device without a power button.

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: Disclosed is a battery protection circuit package capable of ensuring stability of a battery, the package including a substrate having a plurality of external connection terminals and a plurality of internal connection terminals, and a protection integrated chip (IC), one or more field effect transistors (FETs), and one or more passive devices provided on the substrate, wherein the protection IC includes a separate IC structure capable of forcibly blocking discharge or charge of the battery bare cell by switching off the FETs when an electrical signal is input through one of the external connection terminals.

Abstract: A battery protection circuit package is provided which is advantageous for integration and miniaturization. The battery protection circuit package includes: a substrate on which a conductive line pattern is disposed; a battery protection circuit element that is mounted on the substrate and includes a protection IC, a field effect transistor (FET), and at least one passive element; and an NFC antenna structure that is mounted on the substrate, and the conductive line pattern constitutes at least a part of an extension antenna that is connected to the NFC antenna structure to form a loop.
