Abstract: A sliding-type portable terminal including a first housing and a second housing linearly movably coupled to the first housing face-to-face includes a spring module for opening/closing the first and second housings. The spring module includes at least a pair of asymmetrical S-shaped wires each including a first bend and a second bend extending from the first bend and having a greater curvature than the first bend. The spring module of the portable terminal provides a reduced thickness because of the spring action in the portable terminal, contributing in particular to an overall reduction in thickness of a sliding-type portable terminal and permit smooth opening/closing of the portable terminal.

Abstract: Provided is an apparatus and method for detecting a packet of a zero-padded OFDM signal, which are capable of determining if a packet exists in a reception (RX) signal by comparing a cross-correlation value of an OFDM signal delayed by a predetermined sample time, e.g., a zero-padded sample time, with a power value of the RX signal, thereby increasing a packet detection probability and preventing a false alarm. The packet detecting apparatus includes: a cross-correlation calculator for calculating a cross-correlation value of a reception signal received from the outside and delaying the calculated cross-correlation value by a predetermined sample time; a power calculator for calculating a power value of the reception signal; and a packet detector for determining if a packet exists in the reception signal by comparing the delayed cross-correlation value with the calculated power value, and detecting the corresponding packet.
