A display apparatus including a light emitting body to improve external appearance thereof. The light emitting body is disposed inside a bezel to emit light. The bezel has a reflective surface to reflect light emitted from the light emitting body in front of the display apparatus. The bezel also has a light interruption groove to prevent light emitted from the light emitting body from affecting an image formed on the display module. The light emitting body is operatively connected to a user interface unit. A user manipulates a manipulation panel or a remote control to set an operation mode of the light emitting body from a menu item on an on screen display, and the light emitting body emits light in various forms based on the set mode.

A method and apparatus for determining phase sensitivity of an accelerometer based on an analysis of the harmonic components of the interference signal, which can estimate phase lags of an accelerometer through an analysis of the interference signal obtained using a single photo-detector when the accelerometer moves in sinusoidal motion with an initial phase of vibration. The method comprises the steps of obtaining an interference signal in a time domain generated from a signal reflected by an accelerometer and a fixed mirror using a single photo-detector; transforming the interference signal in the time domain into a signal in a frequency domain including a plurality of harmonic signals by Fourier transform; and determining the phase sensitivity of the accelerometer using initial phase of vibration displacement of the accelerometer, which is included in the interference signal in the frequency domain.

The present invention relates to an extracorporeal High Intensity Focused Ultrasound (HIFU) necrosis apparatus through the control of an electronic signal, including oscillation elements for generating ultrasonic beams, an ultrasonic oscillator array having the oscillation elements fixed on a plane and oriented toward a life, delay circuits respectively connected to the oscillation elements for delaying ultrasonic oscillation by a delay time, and control means for controlling the delay time so that the ultrasonic beams are focused, and a method of employing the same. According to the present invention, waved surfaces with a variety of directions and curvatures can be formed using several oscillation elements and several delay circuits disposed on a plane, and a focus can be formed at any desired place. Accordingly, there are advantages in that installation is convenient, and a tissue, such as tumor, which is a target tissue, can be necrotized without damage to normal tissues necrosis. Further, there is no damage to normal tissues other than a target tissue. Accordingly, there are advantages in that a recovery speed of a patient can quicken, a symptom after recovery can be mitigated, and so on.

A backlight unit and a liquid crystal display having the same. The backlight unit includes a lower cover, an interconnection coupling hole, an inverter board, and an interconnection. The lower cover accommodates a printed circuit board, which mounts at least one light emitting diode thereon and is provided at one side thereof with a first connector. The interconnection coupling hole is formed in a bottom surface of the lower cover at a position corresponding to the first connector. The inverter board is disposed on a rear surface of the lower cover to apply a driving voltage to the at least one light emitting diode. The interconnection is provided at one end thereof with a second connector to electrically connect the printed circuit board to the inverter board. A coupling part of the first connector coupled to the second connector is directed to the interconnection coupling hole, so the assembling time of the backlight unit and the liquid crystal display is reduced, thereby improving the productivity of the backlight unit and the liquid crystal display.
