Abstract:
An apparatus for testing the performance of a synthetic aperture radar is provided. The apparatus for testing the performance of a synthetic aperture radar includes: a three-axis motion platform that is coupled to an antenna and driven in roll, pitch, and yaw directions so as to reproduce motion components generated from a pointing plane of the antenna; a target simulator configured to reproduce a ground target; and a system simulator that allows the three-axis motion platform and the target simulator to work in conjunction with each other in real time, and controls the three-axis motion platform and the target simulator. Here, the three-axis motion platform may include a three-axis driver that determines the attitude of the three-axis motion platform, based on position and speed information received from the system simulator. The target simulator may include a target modulator that adjusts the amplitude of an output signal, performs range and phase delays, and reproduces a Doppler component, based on simulation target information received from the system simulator.
Abstract:
An liquid crystal display device, including: m+1 data lines crossing n gate lines defining m×n pixels; m×n thin film transistors in each of the m×n pixels, wherein n thin film transistors in a column m are alternately connected to the mth data line and the m+1th data line; and an electrical connector that connects a 1st data line to an m+1th data line.
Abstract:
Disclosed is an icemaker for a refrigerator includes an ice mold for receiving water and freezing the water to ice, an ejector pivotally installed on the ice mold to eject the ice out of the ice mold, a motor for operating the ejector, a heater body disposed enclosing the ice mold to separate the ice from an inner surface of the ice mold by uniformly heating the ice mold, and a heating coil for applying induced electromotive power to the heater body, thereby allowing the heater body to generate heat.

A built-in refrigerator is disclosed. The built-in refrigerator includes: a main body installed in a sink and having a door at a front side thereof and a machine room at a rear lower side thereof; condenser and compressor respectively installed in the machine room; a cooling fan installed in the machine room, for cooling the condenser and the compressor; and a radiation passage allowing an outside of a front side of the main body to communicate with the machine room to introduce external air into the machine room and discharge internal air of the machine room.
Abstract:
In an apparatus and a method for controlling operation of a linear compressor, operation of a linear compressor is controlled by finding each inflection point as a TDC (top dead center) is 0 by using a current and a displacement vector generated in the linear compressor, determining a duty ratio on the basis of the inflection point and generating a switching control signal according to the determined duty ratio.
Abstract:
The present invention relates to a novel quinazoline derivative compound having the formula (1) as follows: with the constituents defined in claim 1, and a pharmaceutically acceptable salt thereof as a multiplex inhibitor, a method for the preparation thereof, and a pharmaceutical composition and a therapeutic composition comprising same as an active ingredient.
