Abstract: A leveling control system for an acceleration tester includes a support portion installed on a ground, a level portion of which a center is connected to one side of the support portion, a test portion located on one side of the level portion and configured to accommodate a test body, and a control portion located on an other side of the level portion, wherein the control portion includes guide rails formed extending in a longitudinal direction of the level portion and a first weight configured to move along the guide rails.

Abstract: An electronic device and method are disclosed herein. The electronic device includes a communication module, a memory and at least one processor, which implements the method, including responsive to detecting a request to update additional data corresponding to detecting a present location, transmitting a request to update the additional data to at least one external electronic device in communicable range of the communication module, receiving the additional data in response to the transmitted request via the first module of the communication module, detecting a validity of the received additional data, and detecting the present location via the second module of the communication module based at least partially on the additional data if the additional data is detected to be available.

Abstract: An apparatus and method for supporting a handover of a mobile terminal without a Global Positioning System (GPS) are provided. The method includes receiving a sub-cell IDentifier (ID) from a Base Station (BS) using Transmission Parameter Signaling (TPS), recognizing a location of the mobile terminal using the received sub-cell ID, and determining a candidate group of adjacent cells, to which the handover is possible, using the recognized location information of the mobile terminal. Accordingly, the mobile terminal may performs a handover within a short period of time, and a seamless service may be provided by avoiding a possibility that a service Further, in comparison with the conventional handover, power consumption may be reduced by decreasing a frequency search time of an adjacent cell during an off time.
