Abstract: A power control apparatus and method for an electronic device is provided, which utilizes a charge current control module and a feedback signal control module to transfer the power control signal to a remote-controlled adapter through a feedback circuit, to control the output voltage of the remote-controlled adapter so as to adjust the charge current until the total input current supplied by the remote-controlled adapter is equal to the highest total input current. Therefore, the system of the electronic device can be provided with sufficient power to process needed procedures in a safe condition. Besides, according to the power required by the system of the electronic device, the controller can distribute the power for both the system and the battery in order to improve the efficiency of power use.

Abstract: An error sensing method for increasing error control accuracy and efficiency of a data block having a plurality of ECC (error control code) coded words transmitted through a communication media, the method comprising the steps of:(1) inserting a plurality of sensing bits into one or more predetermined positions within the data block;(2) modulating and transmitting the data block to the communication media;(3) receiving and demodulating the data block from the communication media;(4) extracting the sensing bits out of the received data block and calculating a BER by using the extracted sensing bits; and(5) requesting for retransmission if the BER of the received data block is worse than a predetermined BER1 which is approximately equal to the ratio of the number of maximum detectable errors of the ECC to the number of bits contained in one ECC coded word.
