Abstract: Provided is a method of controlling an electronic apparatus, the method including obtaining main motion data and sub motion data, obtaining synthetic data by combining the main motion data and the sub motion data, obtaining a threshold value based on a magnitude of a signal waveform of the synthetic data and a running mean of the synthetic data, identifying a plurality of critical points in the synthetic data based on the threshold value, identifying signal patterns, based on the plurality of critical points, in each axis of a plurality of axes in the main motion data of a 3-Dimension (3D) coordinate system, obtaining at least one similarity in the signal patterns based on a plurality of inter-axis features extracted from the synthetic data, obtaining a degree of symmetry between each axis of the plurality of axes based on the at least one similarity, and obtaining movement information of a user based on the degree of symmetry and the synthetic data.

Abstract: Methods and systems for communicating data between a vehicle and a ground-based unit are provided. The method includes communicatively coupling the vehicle to the ground-based unit, initiating a Broadband over Power Line (BPL) link between the vehicle and the ground-based unit when power is supplied to the vehicle, and updating data stored in the vehicle with data received from the ground-based unit.
