Abstract: A method is proposed to assist a user of an electric vehicle in reserving a rechargeable battery with a charging station. A reservation assistant unit that is related to the electric vehicle computes an estimated travelling distance from a current location corresponding to the electric vehicle to a destination, and computes a remaining distance based on residual electric energy of a rechargeable battery currently used by the electric vehicle. When the estimated travelling distance is greater than the remaining distance, the reservation assistant unit provides charging station information that indicates the closest charging station that has a rechargeable battery available.

Abstract: The present disclosure illustrates a three-dimensional trace verification apparatus and method thereof. The three-dimensional trace verification apparatus includes a signal emitting module and a platform module configured to maintain a fixed relative location. When a motion trace of the platform module is different from a pre-recorded trace of a trace transmitting module, the trace transmitting outputs a deviation signal according to a sensed signal. This mechanism can achieve a technical effect of automatically verifying whether the motion trace of the platform module and the pre-record trace made by a user are the same, and recording the error.

Abstract: The present disclosure illustrates a system for pairing an unmanned aerial vehicle (UAV) and a truck to make the UAV complete goods delivery and a method thereof. In the system, a control server updates truck status data according to truck messages sent from in-vehicle servers set in different trucks, pairs a UAV and one of the trucks according to the truck status data and a UAV message and generates a task message after the control server receives the UAV message, transmits the task message to the UAV and the paired truck. The UAV carries out a task assigned by the task message after the UAV meets the paired truck according to the task message. The system and the method does not need to set up UAV charging stations, and can achieve the effect of improving delivery efficiency.
