    摘要: A remote controller having a function for lighting up a dark place includes a hand generator and a condenser installed inside of a case and a rotating knob installed outside of the case thereby providing for making electricity by supplying the hand generator with a torque, the condenser being connected to the illuminating lamp and to a circuit substrate. The remote controller may be used semi-permanently without replacing a battery often unlike a conventional remote controller having a flash function, thereby greatly reducing use costs and greatly improving customer satisfaction and merchantability.

    摘要: A transmission method based on a Hybrid Automatic Repeat Request (HARQ) scheme for in a communication system. A codeword is generated using a Low Density Parity Check (LDPC) code. Parity bits of the codeword are classified on a basis of a transmission priority. Parity bits with an identical transmission priority are grouped. An information bit group of the codeword and parity bit groups with the identical transmission priority are shuffled in a predefined pattern. A packet is generated from the shuffled information bit group and the shuffled parity bit groups based on the transmission priority. The generated packet is retransmitted in response to a retransmission request. The transmission method can obtain the effect of channel interleaving by setting a transmission priority according to importance of puncturing target blocks, shuffling blocks with the same priority, and shuffling and transmitting bits configuring each block.
