Provided is a wireless power transmission device. The wireless power transmission device includes a power coil in which a high frequency current is applied, a transmission coil in which the high frequency current is induced by magnetic induction, the transmission coil configured to generate an non-radiative electromagnetic wave when the transmission coil has the same resonant frequency as an at least one external target device, and a resonant frequency regulator configured to regulate the resonant frequency of the transmission coil. The wireless power transmission device can transmit the power when it has the same resonant frequency as the target device. Therefore, the overheating due to an eddy current may not occur, and the design may be easily varied.

Abstract:
Disclosed are a sensor node having a self localization function and a self localization method of the sensor node. The sensor node calculates a location thereof by receiving location information measured at each of two mobile nodes at different times and using four location information of the received location information. Additional cost and power consumption required for installing additional equipment such as an anchor node, a ultrasonic transceiver and a signal amplifier are reduced.
Abstract:
Provided are a method and an apparatus that make is possible to measure the amount of greenhouse gas reduced for the stop time of an engine stopped while a vehicle idles. A first amount of fuel consumed in an engine is measured before the engine of a vehicle idling stops. A second amount of fuel consumed for restarting the engine, which is stopped, by idling of the vehicle is measured. Exhaust reduction of greenhouse gas is calculated from idle stop of the vehicle to engine restart, on the basis of the first and second amount of fuel consumed and an engine stop-continued time from an ECU.
Abstract:
Provided is a data protecting device and method. When a specific application requests an access to sealed data, an operating system generates application identity information without interruption by the corresponding application, and writes the generated application identity information in a platform configuration register that can be reset in a trusted platform module. Upon having received the unsealing request, the trusted platform module transmits data to the application when the unsealing condition included in the sealed data block corresponds to the state value of the currently operated platform written in a platform configuration register in the trusted platform module.
Abstract:
The present invention includes a rotation based transformation method for preserving data privacy. A rotation based transformation method according to an embodiment of the present invention divides a given data set into a plurality of data subsets, applies a plurality of different rotation matrixes to the plurality of divided data subsets, respectively, to rotate the plurality of data subsets, and re-concatenates the plurality of rotated data subsets to generate a rotated data set. The rotated data set is released and used for data clustering. The rotation based transformation method is effectively used when the impact of the AK-ICA attack is mitigated. Meanwhile, when the two parties are related to the present invention, the two parties need to agree on parameters, such as the number of data subsets. It is preferable that the data subsets be divided into equal sizes. Further, rotation-unification work that removes relative rotation deviation between the plurality of different rotation matrices can be performed in order to provide valid clustering between the data subsets rotated using the different rotation matrixes.
