摘要:
Remote controller code format(s), transmitting/receiving apparatus thereof, and transmitting/receiving method(s) thereof are provided by which data can be transmitted/received using an intrinsic remote controller code format to prevent reciprocal compatibility with another remote controller of a different manufacturer. The remote controller code format(s) may include a header code, a custom code, a data code, an inverse data code, and an inverse custom code. One frame of the remote controller code format may be arranged in a sequence of the header code, the custom code, the data code, the inverse data code, the inverse custom code, and an end code. One frame of the remote controller code. format may be arranged in a sequence of the header code, the custom code, the inverse custom code, the data code, the inverse data code, a check sum code, and an end code. Also, one frame of the remote controller code format may be arranged in a sequence of the header code, the custom code, the inverse custom code, the data code, the inverse data code, and an end code. A high pulse may have the same length as a low pulse in the header code.

A drum washing machine includes a cabinet including an opening at a front wall of the cabinet to allow laundry to be put into or taken out of the cabinet, a door at the front wall of the cabinet to open or close the opening of the cabinet, and a door opening/closing mechanism connected between the cabinet and the door to move the door above the cabinet when opening the door such that a front surface of the door is upwardly directed when the door is open, and to move the door toward the front wall of the cabinet when closing the door. The door is usable as a laundry holder when the door is open.

A method and apparatus for estimating a sampling frequency offset (SFO) in a digital receiver is disclosed. The method for estimating the SFO in the digital receiver to perform sampling synchronization includes the steps of: a) extracting a current scattered pilot contained in a single OFDM (Orthogonal Frequency Division Multiplexing) symbol interval; b) calculating a phase value using both the extracted current scattered pilot and a delay value acquired when the current scattered pilot is delayed by four symbol intervals; and c) estimating an SFO value using the calculated phase value. Therefore, the method correctly estimates the SFO value using the scattered pilot as compared to a conventional estimation method based on a continual pilot (CP), and reduces a jittering range caused by overshoots using a zero-forcing algorithm, such that it solves an SFO estimation failure caused by serious phase distortion.

The present invention provides a method for producing nano-sized Fe powder having a polymer coated layer on a surface thereof, so as to prevent the nano-sized Fe powder from being oxidized under atmosphere. The method includes: gasifying an iron pentacarbonyl (Fe(CO)5) or an iron acetate ((CH3CO2)2Fe) precursor in a ceramic bubbler; forming nano-sized Fe particles due to the crystallization of Fe gas while mixing the gasified precursor with Ar gas in a reactor; and precipitating the nano-sized Fe particles in a polymer solution in a chamber, before the nano-sized Fe particles are oxidized. According to this technique, Fe powder on the order of tens of nms in size, and having a polymer coated layer, are obtained from the Fe precursor. A system for producing the nano-sized Fe powder is also disclosed.

A cleaning robot and a control method thereof in which a cleaning path desired by the user is recognizable by the cleaning robot, thereby being capable of cleaning a cleaning area desired by the user in a pattern desired by the user. The cleaning robot includes a running unit to run the cleaning robot, a storage unit for storing a running path, along which the cleaning robot has learned, and a control unit to recognize the learned running path of the cleaning robot when a path learning operation is required, to store the recognized learned running path in the storage unit, and to drive the running unit. When a cleaning operation of the cleaning robot along the stored learned running path is required, the control unit controls the running unit to cause the cleaning robot to perform the required cleaning operation while running along the stored learned running path. The user can directly input, to the cleaning robot, a cleaning path desired by the user, in order to cause the cleaning robot to perform a cleaning operation while running along the learned running path. Accordingly, it is possible to accurately inform the cleaning robot of various areas associated with the cleaning operation, for example, an area to be repeatedly cleaned at several times, or an area to be prevented from being cleaned.
