Disclosed are a roll-to-roll printing system and method in which a large number of micro-nozzles are formed directly in a printing roll, and thus ink supplied to the central portion of the roll can be formed into micro-inkjets by inducing an electrostatic field, and furthermore, as a result of the formation of the micro-inkjets, a micro-sized pattern significantly smaller than that achievable by a prior pattern formation method can be printed on a print medium, and in addition, the relative speed of the print medium relative to the roll can be maintained at a speed close to “0” so as to improve the resolution, integration density and precision of the printed pattern.According to the present invention, a large amount of micro-nozzles are formed directly in a printing roll, and thus ink supplied to the central portion of the roll can be formed into micro-inkjets by inducing an electrostatic field.

The present invention relates to a prediction-based dynamic thread pool management method and an agent platform using the same. An prediction-based dynamic thread pool management method according to the present invention includes: (a) calculating a thread variation to a variation of the number of threads at a time t1, (b) calculating the number of expected threads expected at a time t2 on the basis of the thread variation, (c) determining a change of the thread variation according to the time elapsed, and (d) decreasing an executing frequency of said steps (a) and (b) when it is determined that the change of the thread variation at said step (c) is small and increasing the executing frequency of said steps (a) and (b) when it is determined that the change of the thread variation is large.

A refrigerator including an ice making device to make ice and a control method of the refrigerator. The refrigerator includes the ice making device to make ice, and an ice reservoir disposed below the ice making device to receive the ice made by the ice making device. The ice making device includes an ice-full state sensing lever installed, in a vertically pivotally rotatable manner, at one side thereof to sense whether or not the ice reservoir is full of ice, and a lever cover to cover a side surface of the ice-full state sensing lever. With the use of the lever cover, even if the ice is caught between a wall surface of an ice making compartment and the ice making device, the ice is caught between the wall surface of the ice making compartment and the lever cover. This has the effect of assuring a stable operation of the ice-full state sensing lever.

There is provided a power amplifying device having a linearizer in which a bias circuit has an initial impedance set when initially operated, then the impedance is varied according to a level of an input signal and the input signal is amplified in a broad range from a low level region to a high level region, thereby improving linearity of an output signal. The power amplifying device including: an amplifying unit receiving a bias power source and amplifying an input signal; a bias unit varying the bias power source according to a set impedance to provide to the amplifying unit; and an impedance setting unit setting the impedance of the bias unit in response to a preset control voltage when the bias unit is initially operated and re-setting the impedance of the bias unit according to a level of the input signal of the amplifying unit after initial operation of the bias unit.

Provided is a low-power wireless communication apparatus and method. In the apparatus, a low-noise amplifier amplifies an RF signal in an on state, the low-noise amplifier be turned on/off according to a predetermined control signal. A wake-up signal detector detects a wake-up signal from the amplified RF signal. A controller provides the predetermined control signal such that the low-noise amplifier and the wake-up signal detector operate at a predetermined on-off duty ratio in a sleep mode corresponding to an Rx waiting state, and switching to an Rx mode to maintain the on state of the low-noise amplifier when the wake-up signal is detected.

A character input system and method is provided that enables a user to input and edit block characters via a touch-based electronic device, with a limited number of input motions. The character input method includes receiving a first interaction, displaying a first character in response to the first interaction, receiving a second interaction successively after the first interaction, identifying a second character that is formed by combining the first character with a character according to the second interaction, and displaying the second character instead of the first character.
