Abstract: Disclosed herein is an internal antenna capable of mitigating the effect of electromagnetic waves on a human body using coupling. The internal antenna includes an antenna pattern part and a conductive conductor pattern. The antenna pattern part is form on the Printed Circuit Board (PCB) of a mobile communication terminal. The conductive conductor pattern is formed in a predetermined pattern on one side surface of a cover which covers the antenna pattern part. Coupling occurs between the antenna pattern part formed on the PCB and the conductive conductor pattern formed in a predetermined pattern on one side surface of the cover, so that current components are transferred from the antenna pattern part to the conductive conductor pattern.

Abstract: A method of detecting a free fall of a device includes measuring an acceleration of the device, calculating an integral of the acceleration, and determining whether the acceleration is periodic. If the acceleration is not periodic, the integral of the acceleration is compared with a first critical value to determine whether the device falls freely. If the acceleration is periodic, the integral of the acceleration is compared with a second critical value to determine whether the device falls freely. The first and second critical values are different. Since whether the device is periodically accelerated is considered, free fall of the device can be correctly detected, and thus malfunction of the device can be prevented. For example, an unnecessary protection operation for a hard disk drive of the device can be prevented, and thus a user can conveniently use the device.
