Abstract: Disclosed herein is an over-the-range oven including a body provided with a suction port and an exhaust port, an air blower unit causing air to be suctioned through the suction port and discharged through the exhaust port, and an air curtain unit movably installed at a lower portion of the body to generate an air curtain by discharging air. Since the air curtain unit is movable between a first position at which the air curtain unit is disposed close to the body and a second position at which the air curtain unit protrudes from the body, it may allow gas produced by a cooking apparatus disposed below the air curtain unit to be efficiently discharged.

Abstract: An air conditioning system, a vortex tube, a vortex generating member, and a method for controlling an air conditioning system are provided. The air conditioning system includes a vortex tube that produces cold air and hot air, a blower device that supplies air to the vortex tube, and an indoor unit located in an indoor space that selectively releases one of the cold air and the hot air produced from the vortex tube to the indoor space.

Abstract: A media transfer method and apparatus enable media to be separated and discharged out of a media cassette of a media dispenser with a uniform transfer interval. The media transfer apparatus includes a pickup roller in contact with media waiting to be discharged, so as to separate and transfer the media sheet by sheet. A main feed roller and a delivery roller transfer a separated sheet of the media to a media transfer route. A sensor detects a front end of the separated sheet, having passed through a juncture between the main feed roller and the delivery roller. When the sensor detects the front end of the separated sheet, a power supplied to the pickup roller is stopped, and the separated sheet continues to be transferred by the driving power of the main feed roller and the delivery roller.

Abstract: A media sensing method of a media dispenser is disclosed capable of discriminating various media and accurately discriminating whether a media is normal by using the least sensors. The media sensing method of a media dispenser includes: setting an initial reference range for width and thickness of a media; comparing the initial reference range and a reference range of a currently discharged media; and variably setting a new initial reference range on the basis of the comparison value, thereby discriminating whether media is normal or abnormal. Accordingly, without using an additional sensor, a cost in manufacturing the media dispenser can be reduced, an error caused by various environmental conditions or a deflection taking place in setting sensors can be effectively prevented, a multi-media overlap can be accurately discriminated, and the thickness of discharged multimedia can be precisely measured.

Abstract: A control system and a method of a media dispenser with which a user can selects preferable media and dispenses preferable kinds of media can broaden the usefulness media and can recollect abnormal media existing in the media feeding path thus to ease the use. The control system includes a driving motor installed at one side of the base plate in which a media cassette is positioned, for generating driving force, a clutch installed at one side of a media pickup part which discharges media stored in the media cassette and connected to the driving motor, for selectively transmitting the driving force generated in the driving motor to the media pickup part and a clutch controlling means for controlling operation of the clutch by turning on/off a power source applied to the clutch so that the media can be discharged from the media cassette consequently.

Abstract: A media sensing method for an automatic media dispenser for discriminating discharged media using minimum sensors is able to sense media which are discharged in abnormal status by discriminating skew of media, length of the media, thickness of the media, and a distance between successively discharged media using a feed sensor and a rotary variable differential transducer (RVDT) sensor installed on left/right sides of a transferring path on which the media are transferred after being discharged from a cassette as responding to a cash withdrawal request, and thereby an area for disposing the sensors can be reduced to minimize the dispenser, and the circuit can be constructed simply using the minimum sensors to reduce fabrication cost for the automatic media dispenser.
