Abstract: Provided are an airway setting device for signaling an airway to an aerial vehicle and an automatic navigation system for controlling the aerial vehicle to fly the airway. The airway setting device transmits radio frequency (RF) signals through two antennas spaced apart from each other. The transmitted RF signals are encoded with phase difference information intended for an aerial vehicle receiving the transmitted RF signals. An automatic navigation system of the aerial vehicle receives the RF signals from the two antennas spaced apart from each other, measures a phase difference between the RF signals, decodes encoded phase difference information, and compares the measured phase difference with the decoded phase difference to identify and maintain an airway.

Abstract: A flight guidance technique for guiding an aerial vehicle to track a target is provided.

Abstract: Disclosed herein is a stereoscopic image display apparatus capable of wirelessly transmitting and receiving power. The stereoscopic image display apparatus includes a stereoscopic image display unit and shutter glasses. The stereoscopic image display unit divides stereoscopic images into images for the left eye and images for the right eye and displays the resulting stereoscopic images, generates a signal of opening/closing a right eye shutter and a left eye shutter, and generates a power signal and then wirelessly transmits power in a magnetic resonance coupling manner. The shutter glasses wirelessly receives the power signal from the stereoscopic image display unit in the magnetic resonance coupling manner, and provides the images for the left eye and the images for the right eye by alternatively opening and closing the left eye shutter and the right eye shutter in response to the signal of opening/closing the right eye shutter and the left eye shutter.

Abstract: An apparatus and method for providing a storage medium accessible across a network to a host. The storage medium's operation is generally controlled by a network disk controller. The network disk controller may receive a packet from a remote host, decapsulate the packet, and act on the packet to either transmit data from a storage medium or write data to a storage medium. Generally, the network disk controller does not execute any file system. Rather, the file system for communication between the host and controller is executed by the host. The performance of the network disk controller generally matches that of a local (i.e., non-network) disk controller in terms of data access and writing.
