Abstract:
The present invention relates to a method for selecting an appropriate mode when performing a new broadcast, such as a 3D stereo broadcast, a UHDTV broadcast, and a multi-view broadcast, among others, while maintaining compatibility with existing broadcasting channels in an MPEG-2-TS format for transmitting and receiving digital TV, and to a method for recognizing a descriptor. To this end, the present invention suggests providing the descriptor which is related to synthesizing left and right images using the type of stream, existence of the descriptor, and a frame-compatible mode flag.
Abstract:
Provided are an apparatus and method for controlling a virtual mouse based on a hand motion. The apparatus includes an image processing unit configured to measure a maximum horizontal width of a hand region of a user and a width of an index finger in any one of a first depth image captured in a state in which the index finger is spread out in a vertical direction with his or her fist and a second depth image captured in a state in which the index finger is folded with the fist, a hand motion recognizing unit configured to compare the maximum horizontal width and the width of the index finger to recognize whether the index finger is folded, and a function matching unit configured to match a change in a folded state of the index finger to a pre-set first function and output a control signal for the function.

Abstract:
An inverter apparatus having a power supply circuit includes a converter circuit for rectifying AC power into DC power, a smoothening circuit for smoothening the rectified DC power, an inverter circuit for converting the smoothened DC into AC at a variable frequency through a plurality of switches to control a load, and a current detection circuit for detecting overcurrent from the smoothened DC supplied from the inverter circuit, wherein the inverter circuit applies bootstrap power for driving the switches to the current detection circuit to use the bootstrap power as power of the current detection circuit. When bootstrap power for driving switch gates is used, it is possible to use the bootstrap power as the power of the current detection circuit by adding the auxiliary circuit composed of a small number of passive elements.
Abstract:
The present invention relates to an image display apparatus and method for displaying a three-dimensional (3D) image capable of interacting with a user, and provides a 3D image display apparatus and method that may interact with a user by reproducing a 3D image, generated by a conventional volume display apparatus, at a position different from a position at which the 3D image is generated, and by modifying and playing the reproduced 3D image based on a motion of the user. Also, the present invention enables the user to realistically interact with the 3D image by stimulating tactile sensation of the user through ultrasound.
Abstract:
A patch antenna having a single patch fed with multiple signals is provided. The patch antenna includes: a first patch; a first feeder and a second feeder which are connected to the first patch; and a second patch which is parallel to the first patch. Accordingly, since multiple signals can be fed into a single patch, a MIMO antenna can be embodied by using a patch antenna which has high isolation between feeders without increasing its size.
Abstract:
A method and system for detecting a fault of a serial coil type permanent magnet motor includes driving the motor based on a predefined current reference value, detecting a phase current vector of the motor, and calculating a current compensation value for removing a negative sequence component of the motor based on the phase current vector. The current compensation value is provided to a negative sequence current controller for calculating a faulty phase and a degree of a fault of the motor using the output of the negative sequence current controller and a fault model to which induced magnetic flux variations in a specific slot of a specific faulty phase of the motor and other slots of the same phase as the specific phase are applied, and applying a current reference value to which the calculated faulty phase and degree of fault are applied.
