A motion type decision apparatus and method thereof are provided. A first decision unit determines the presence of motion in a current block for compensation, by extracting first and second high frequency signals from first and second blocks of a previous and a current frame/fields corresponding to a zero motion vector of the current block to set a first threshold, and comparing a first motion estimation error value between the first and the second blocks with the first threshold. A second decision unit determines the presence of motion in the current block, by extracting third and fourth high frequency signals from third and fourth blocks, setting a second threshold, and comparing a second motion estimation error value with the second threshold. A motion type decision unit determines a motion type of the current block by comparing the motion determinations of the first and the second decision units.

A wafer dryer for use in a semiconductor cleaning apparatus includes an internal bath, an external bath, a solution supply line, a solution drain line, a pump, and drying means. The solution drain line has a first drain line and a second drain line. A pump for constantly maintaining a speed of a drained solution is installed on the first drain line. The drying means has an isopropyl alcohol (IPA) nozzle, a first gas spray nozzle for spraying N2 gas, and a second spray nozzle. The second spray nozzle is installed on all inner sidewalls of the external bath and has a plurality of holes. Thus, no wave is produced at a surface of the drained solution.

A method of correcting a print error caused due to a misalignment between chips mounted on an array head of an inkjet printer. The method includes calculating an acceptable limit of a rotation angle of the chips with respect to reference positions, based upon a range that does not cause a white band to form on a printed image; determining whether the rotation angle of each chip is within the acceptable limit or not; correcting a machine error of each chip if it is determined that the rotation angle of each chip is not within the acceptable limit; if the rotation angle of each chip is within the acceptable limit, adding a plurality of nozzles on at least one end of each chip, determining which of the added nozzles to use based on a predetermined trial printing pattern, and correcting a print error in a horizontal direction that is caused due to a misalignment in the horizontal direction; and correcting a print error in a vertical direction due to a misalignment between the chips in a vertical direction by determining a reference time for voltage pulse application to a heater disposed on a nozzle of the array head based on the predetermined trial printing pattern, by variably determining voltage pulse application time, thereby adjusting a time interval for an ink ejection from the respective chips.

In an apparatus for fabricating a fluid bearing having a dynamic-pressure-generating track slot installed in the internal diametric surface of a sleeve, a ball-escape-preventing device is coupled with a rotary shaft being in contact with one end thereof so as to form the identical outer diametric surface with that of the rotary shaft to support the ball. Therefore, it is not necessary to control the angular velocity and axial transfer velocity of a guide bushing or ring with respect to those of the rotary shaft. Also, a fluid bearing of a high precision and high efficiency can be fabricated with an inexpensive and simple device by which ball wear due to rolling can be reduced and the ball is easily replaced when worn.

A substrate aligning unit includes a first driving roll, a second driving roll, a web guider, an encoder roll, and a controller. The first driving roll transfers a substrate in a first direction. The second driving roll is disposed spaced apart from the first driving roll in the first direction and transfers the substrate in the first direction. The web guider controls a position of the substrate in a second direction substantially perpendicular to the first direction. The encoder roll senses the position of the substrate to generate a sensing signal. The controller controls the first driving roll, the second driving roll, and the web guider based on the sensing signal.

A robot controller controls a robot to maintain balance in response to an external disturbance (e.g., a push) on level or non-level ground. The robot controller determines a predicted stepping location for the robot such that the robot will be able to maintain a balanced upright position if it steps to that location. As long as the stepping location predicted stepping location remains within a predefined region (e.g., within the area under the robot's feet), the robot will maintain balance in response to the push via postural changes without taking a step. If the predicted stepping location moves outside the predefined region, the robot will take a step to the predicted location in order to maintain its balance.

Provided is a multi-route routing scheme that supports Quality of Service (QoS) in the wireless mesh network. A method of notifying about and avoiding congestion situation in data transmission in a wireless mesh network and a mesh node may also be provided. Data may be differentially transmitted to multiple routes by obtaining a route congestion level existing in a current multi-hop route and thus, data providing a real-time service, such as a video streaming service, may avoid congested routes and may be promptly transmitted. Multiple queues in a mesh node may be divided into divided queues based on a congestion situation of a transmission route in a network and the divided queues may be transmitted through multiple routes and thus, an efficiency of the overall network may increase.
