Abstract: A multi air conditioner system in one example performs a cooling and heating changeover by selectively granting priority to one or more indoor units, determining whether there is one or more operating indoor units with priorities, and granting a control right for auto changeover to at least one indoor unit with priority.

Abstract: A pipe-connection searching apparatus and method for a multiple air conditioner. The apparatus and method involving the identification of one of a plurality of indoor units, based on temperature criteria, and matching the one indoor unit to a corresponding one of a plurality of pipes that connect an outdoor unit to the plurality of indoor units, respectively.

Abstract: A liquid crystal display device and a driving method thereof, which are capable of preventing generation of a residual image upon power-off, are disclosed. The liquid crystal display device includes a power supply unit for outputting a plurality of drive voltages after delaying the drive voltages, a voltage detector for monitoring one of the drive voltages, and outputting a power-off detect signal based on the result of the monitoring, a timing controller for increasing a frequency of a control signal in response to the power-off detect signal, and outputting the frequency-increased control signal, a gate driver for outputting a scan signal in response to the frequency-increased control signal, a data driver for outputting a constant voltage in response to another control signal from the timing controller, and a liquid crystal panel for applying the constant voltage to all sub-pixels of the liquid crystal panel in response to the scan signal.

Abstract: A method and apparatus for extracting three-dimensional data of an object using an electron microscope are provided.
