Abstract: A wireless communication system using mimicked near field communication is disposed in a peripheral application device and configured to be connected with a mobile device. The system includes a wireless communication module configured to send a control command, and an RF switching circuit configured to be switched to a low or normal power mode according to the control command. Under the low power mode, a signal attenuation unit of the RF switching circuit attenuates a frequency of a transmission signal emitted from the wireless communication module to generate an output signal. Under the normal power mode, the signal attenuation unit maintains the frequency of the transmission signal. The signal frequency is allowed to be attenuated during an authentication phase to thereby achieve near field communication, and an original wireless transmission mechanism is allowed to be used after authentication is completed so as to perform operation of the peripheral application device.

Abstract: A dynamic taxi-sharing system and a sharing method thereof. A ride-sharing service provider carries at least one passenger from the first current location to the first travel destination through a route in an area and sends registration information to a service server. A plurality of ride-sharing requests is sent to the service server, and each of the ride-sharing requests comprises the second current location and the second travel destination. The service server divides the area into n by n blocks. A ride-matching module of the service server chooses a destination area in which the first travel destination is a center point and divides the destination area into k by k blocks. According to the registration information and the ride-sharing requests, the ride-matching module matches at least one ride-sharing traveler to the ride-sharing service provider to achieve a goal of fuel-saving and pollution-reducing.

Abstract: A fuel-saving path planning navigation system and a fuel-saving path planning method thereof. A plurality of sensors monitors a plurality of roads respectively and periodically report traffic information to a server. The server comprises a storing module and a processing module. The storing module stores the traffic information as history information. The processing module estimates how many vehicles on a road based upon the history information, calculates fuel consumption of each possible planned path including current fuel consumption based on real-time traffic and future fuel consumption based on the historical information, and plans a most fuel-efficient path. Also, the processing module recalculates fuel consumption of remaining path and changes the remaining path while fuel cost of a new path better 10% than the remaining path.

Abstract: The present invention relates to a method for selecting sensor nodes, the method is adopted for calculating the value of a contribution function for a plurality of objects contributed by a plurality of sensor nodes, wherein the contribution function value is calculated by way of determining a coverage level of the objects made by the sensor nodes, or by means of arranging a sub sensor node group capable of sensing covering an object group and calculating the value of the contribution function for the objects contributed by the sensor nodes; Therefore, through the method, the sensor nodes having maximum contribution to the objects can be selected and arranged in a specific environment, and the sensing direction of those sensor nodes can be adjusted for making the sensor node group performs the best efficiency.
