A method in which a second electronic device communicates with a neighbor device is provided. The method includes connecting to a first electronic device, receiving first information for a third electronic device from the first electronic device, and controlling the third electronic device using the first information, wherein the first information includes control right information for the third electronic device.

Method for communicating with neighbor device, electronic device, and storage medium

Disclosed herein are an apparatus and method for detecting an obstacle adaptively to vehicle speed. The apparatus includes a control unit, a speed-adaptive camera sensor, a speed-adaptive laser scanner sensor, and a detection data integration unit. The control unit receives information about the speed of a vehicle and a Pulse Per Second (PPS) signal from a Global Positioning System (GPS) module. The speed-adaptive camera sensor adjusts the range of a detection region based on the information about the speed of the vehicle, and generates first detection data on an object. The speed-adaptive laser scanner sensor adjusts the range of the angle of the field of view of a laser scanner based on the information about the speed of the vehicle, and generates second detection data on the object. The detection data integration unit outputs obstacle detection data.

Disclosed herein are a method and apparatus for generating multiband Radio Frequency (RF) signals in maritime wireless communication. The apparatus includes a baseband conversion unit, a phase compensation unit, a Direct Current (DC) offset compensation unit, and an RF transmission unit. The baseband conversion unit converts RF signals corresponding to a baseband modulation signal having a negative frequency and a baseband modulation signal having a positive frequency into baseband signals, respectively. The phase compensation unit eliminates the images of multiband signals so as to correspond to the baseband signals. The DC offset compensation unit compensates the baseband modulation signals for DC offsets using the multiband signals from which the images have been eliminated. The RF transmission unit generates the RF signals using the signals which have been compensated for the DC offsets, and sends the RF signals via an antenna.

Disclosed herein is a method of providing vehicle wireless communication. In the method, a vehicle receives hand-over-related link information, which includes slot request information about slots requested by a vehicle to a roadside wireless communication device for hand-over of the vehicle, from a central control server. A hand-over preparation message, which includes the hand-over-related link information, is send to a vehicle wireless communication device connected to the vehicle. It is determined that the vehicle completed preparation for performance of the hand-over when a response message to the hand-over preparation message is received from the vehicle wireless communication device. Slots are allocated in consideration of the hand-over-related link information. Beacon frames, which include slot allocation information about the allocated slots, are transmitted to the vehicle wireless communication device. Accordingly, the vehicle wireless communication device and the roadside wireless communication device can reliably perform communication without interruption.

Disclosed herein is an apparatus for detecting locations of a vehicle and an obstacle. The apparatus for detecting locations of a vehicle and an obstacle includes at least one distance measurement unit and a data processing unit. The distance measurement unit measures distance data relevant to a vehicle and an obstacle within a measurement area. The data processing unit maps the distance data on a grid layer, detects the location of the vehicle based on the result of the mapping, detects the location of the obstacle based on the detected location of the vehicle, and modifies the detected location of the vehicle using the distance data.

Apparatus and method for detecting locations of vehicle and obstacle

Provided is a method capable of providing an improved response property appropriate for the characteristics of a system by automatically choosing an interrupt handling mode used for each device. The method is a method in which the embedded operating system kernel determines a handling mode for all individual interrupts, the method includes: dividing interrupt handling modes into a first interrupt handling mode and a second interrupt handling mode which has a different process speed from the first interrupt handling mode, and variably determining a distribution ratio in which each of the interrupts are distributed to the first interrupt handling mode or to the second interrupt handling mode according to a predetermined process condition during boot-up.

Interrupt-handling-mode determining method of embedded operating system kernel

Provided is a user interface apparatus that can control a telematics terminal safely and comfortably while driving, by recognizing a hand gesture image received through a camera in the telematics terminal as a corresponding control signal, and a method thereof. The interface apparatus using a hand gesture recognition, includes: an input receiving block for receiving a command registration request signal and a command selection signal; a hand gesture recognizing block for storing the hand gesture image in connection with a specific command, and transforming the hand gesture image into the corresponding command by recognizing the hand gesture image from the image obtained in the image obtaining block; and a command performing block for performing an operation corresponding to a command transformed in the hand gesture recognizing block.

User interface apparatus using hand gesture recognition and method thereof

'An adaptive hybrid automatic repeat request system and method include transmitting a data frame having channel-coded data and a parity bit using an initial coding rate, receiving the data frame and performing channel decoding and correcting any error that exists. When the error is not corrected, an error degree of a corresponding frame is measured and a NACK message to which the measured error degree is added is transmitted to the transmitting terminal. A parity frame is retransmitted by channel coding a parity bit corresponding to a parity level determined in accordance with the error degree added to the NACK message, and is combined with a data bit of a data frame in which error correction fails. Channel decoding and error correction are then performed.'
