20130043871 | METHOD AND APPARATUS FOR CONTROLLING AN AMPLIFIER OF A MAGNETIC RESONANCE IMAGING DEVICE - An magnetic resonance imaging (MRI) device includes at least one amplifier, a control module which controls an operating module of the at least one amplifier, a back-up control module, a determination unit for determining whether the control module is operating normally, and a switching module for performing a switching operation to switch operations of the control module to the at least one back-up control module in the event of abnormal operation of the control module. | 02-21-2013 |
20140062484 | MAGNETIC RESONANCE IMAGING (MRI) APPARATUS AND MANUFACTURING METHOD THEREOF - A magnetic resonance imaging (MRI) apparatus and method of manufacture including shims provided in outermost or an innermost part of a gradient coil unit. The MRI apparatus includes: a static coil unit configured to form a static field in a subject; and a gradient coil unit configured to form a gradient field in the static field, wherein the gradient coil unit includes one or more shims in an outermost part or an innermost part. | 03-06-2014 |
20140084929 | MAGNETIC RESONANCE IMAGING (MRI) APPARATUS AND MANUFACTURING METHOD THEREOF - A magnetic resonance imaging (MRI) method and apparatus in which conductors are installed in the space between a static coil unit and a gradient coil unit to eliminate asymmetry of eddy current induced in the static coil unit. The structure permits a symmetrical distribution of eddy current when the concentric arrangement of the static coil unit and gradient coil unit has deviated. The MRI apparatus includes: a static coil unit configured to form a static field in a subject; a gradient coil unit configured to form a gradient field in the static field; and one or more conductors installed in the space between the static coil unit and the gradient coil unit, and configured to symmetrically distribute eddy current induced in the static coil unit. | 03-27-2014 |

20090066677 | Display Apparatus Including Wirless Communication Device and Method of Operating the Same - A display apparatus and a method of operating the same are provided. The display apparatus includes a wireless communication device, and a display unit that receives a main clock and is operated by an operating frequency in response to the frequency of the main clock, and a main-clock-providing unit that measures noise in signals received from a wireless communication channel, and changes the frequency of the main clock to reduce the noise. | 03-12-2009 |
20090091270 | LIGHT SOURCE UNIT, A BACKLIGHT UNIT HAVING THE LIGHT SOURCE UNIT AND A LIQUID CRYSTAL DISPLAY HAVING THE BACKLIGHT UNIT - A light source unit, including: at least one light source array having a plurality of light sources; a first resistive element connected in parallel to at least one of the light sources disposed at a first end of the light source array; and a second resistive element connected in parallel to at least one of the light sources disposed at a second end of the light source array. | 04-09-2009 |
20100156302 | Method of Driving a Light Source, Light Source Apparatus for Performing the Method and Display Apparatus Having the Light Source Apparatus - A light source apparatus includes a light source module, a light sensor, a data converter, a light source controller and a light source driver. The light source module includes a light source. The light sensor generates sensing data by sensing the amount of light generated from the light source. The data converter converts the sensing data which exceeds a maximum value of reference data of a control range into converted sensing data within the control range. The light source controller generates a control signal for controlling the amount of light from the light source based upon the sensing data corresponding to no more than the maximum value or based upon the converted sensing data. The light source driver drives the light source by providing the light source with a driving signal based upon the control signal. | 06-24-2010 |

20090199528 | MANUFACTURING METHOD OF FILTER MEDIA AVAILABLE AT MEDIUM AND HIGH TEMPERATURE EXHAUST GAS USING FOAM COATING TECHNOLOGY AND FILTER MEDIA MANUFACTURED THEREBY - Disclosed herein is a method of producing a filter medium for treating medium and high temperature exhaust gas using foam coating and a filter medium produced using the method. The filter medium has excellent heat resistance and heat contraction resistance, and exhibits partial dust collection efficiency of 99% or more by weight, total dust collection efficiency of 99.999% or more by weight, and high dust removal efficiency, for all dust particle sizes. Further, the filter media can be efficiently used to treat medium and high temperature exhaust gas because pores having an average pore size of 30 μm or less are uniformly distributed on the surface of the filter media. | 08-13-2009 |
20100123695 | METHOD OF DRIVING LIGHT-EMITTING DIODES, BACKLIGHT ASSEMBLY FOR PERFORMING THE METHOD AND DISPLAY APPARATUS HAVING THE BACKLIGHT ASSEMBLY - A method of driving light-emitting diodes (LEDs), a backlight assembly for performing the method, and a display apparatus having the backlight assembly are disclosed for various embodiments. For example, the backlight assembly includes a light source unit and a light source controller. The light source unit includes red, green, and blue LEDs generating red, green, and blue light, respectively. The light source controller detects amounts of the red, green, and blue light, respectively, to compare the actual light amount ratio of the red, green, and blue light with the reference light amount ratio. The light source controller controls the red, green, and blue LEDs, respectively, so that an actual light amount ratio becomes substantially identical to a reference light amount ratio when the actual light amount ratio is not identical to the reference light amount ratio. | 05-20-2010 |
