A coasting driving control method and system for a vehicle may determine virtual engine RPM for a current driving state using engine RPM, vehicle speed, and gear stage information by a controller when coasting is started with the clutch in the neutral position and outputs a downshifting instruction signal for a gear stage by the controller when the virtual engine RPM is less than a coasting engine RPM which is greater than an idling RPM by a predetermined value.

An antenna having a broad bandwidth and a high radiation efficiency is provided. The antenna includes a conductor, and a dielectric substrate disposed on the conductor. The antenna further includes a slot portion formed on the dielectric substrate, and a cavity formed in the dielectric substrate that corresponds to the slot portion.

Antenna having broad bandwidth and high radiation efficiency

An antenna is described including a slot formed in a cavity, a substrate configured to cover a portion of the cavity and the slot, and a first port and a second port configured to supply power to the antenna using a first feeding line and a second feeding line. Each of the feeding line and the second feeding line is connected to the slot in a vertical direction and disposed to be separate from one another. A first input impedance of the antenna from the first port differs from a second input impedance of the antenna from the second port.

A wireless power transmission device, a wireless power transmission control device, and a wireless power transmission method are provided. A coupling frequency between a source resonator and a target resonator is determined. A transmission frequency is controlled such that power is transmitted from the source resonator to the target resonator at the coupling frequency. Therefore, it is possible to maintain a high power transmission efficiency without using an additional matching circuit even when a distance between the source resonator and the target resonator is changed.

Wireless power transmission device, wireless power transmission control device, and wireless power transmission method

The present invention relates to a system for transferring wireless power or signal. The system includes a first antenna; and a second antenna which is located from the first antenna at an arbitrary distance and arranged in an arbitrary direction in comparison with the first antenna, wherein respective spherical modes of the first antenna and the second antenna are allowed to have orders which are same as or larger than a predetermined value to thereby transfer wireless power between the first antenna and the second antenna.

Method, system and computer-readable recording medium for transferring wireless power by using antennas with high orders of spherical modes

A bumper beam assembly for a vehicle may include a back beam disposed inside a vehicle bumper, both distal ends of the back beam being oriented in a lateral direction of a main body of the vehicle, crash boxes coupled to one side of the back beam, the crash boxes protruding from the both distal ends of the back beam toward the bumper, and back beam stays integrally coupled to the other side of the back beam, the back beam stays protruding from the both distal ends of the back beam toward an inside of the vehicle, in a direction opposite to a direction in which the crash boxes protrude.

The present invention includes a class-E power amplifier, comprising a driver stage (DS) including a first power amplifier with transistors, to which an input signal is inputted; a main stage (MS), including a second power amplifier with transistors, whose input is connected to the output of the DS; and a first LC resonator whose one end is connected to the output of the DS and the other end to the ground as an AC equivalent circuit and a second LC resonator whose one end is connected to the input of the MS and the other end to the ground as an AC equivalent circuit. In accordance with the present invention, as the voltage stress is reduced on the CMOS class-E power amplifier, the application of the high power supply voltage may be allowed and therefore the load impedance may be high while the same efficiency is maintained.

Class E power amplifier

A deflection yoke comprising a coil separator having a rear plate and a neck part which are defined therein and a printed circuit board which is positioned on a side thereof; at least one horizontal deflecting coil disposed on a circumferential inner surface of the coil separator to produce a horizontal magnetic field and connected to the printed circuit board; at least one vertical deflecting coil disposed on a circumferential outer surface of the coil separator to produce a vertical magnetic field; a ferrite core placed on the circumferential outer surface of the coil separator to reinforce the horizontal and vertical magnetic fields of the horizontal and vertical deflecting coils; insulating means defined on an inside surface of the coil separator to prevent a short from being generated due to a contact between one end and the other end of the horizontal deflecting coil connected to the printed circuit board; and coil distance maintaining means defined on an outer surface of a side of the coil separator to secure a safe distance between the horizontal and vertical deflecting coils of the rear plate, to isolate the horizontal and vertical deflecting coils from each other.
