Abstract: PURPOSE: A method for switching an AAL using an AAL2 is provided to use the set ATM virtual channel band width for an AAL2 connection. CONSTITUTION: An input FIFO stores inputted ATM cells(301). An AAL2 receiving task reads a cell from the input FIFO and processes a cell header if an ATM to be processed exists(303). The AAL2 receiving task reads a VCI value and searches a VCI value of a VCI-CID look-up table(307). The AAL2 receiving task reads and processes an AAL2 STF value. In the case of being overlapped, the AAL2 STF value is processed by using a CID split and CID part located in a processing table by virtual channels. In the case that an AAL2-PH is overlapped, an AAL2 CPS-PH is primarily completed by finding the corresponding temporary buffer. In the case that an AAL2-CPS payload is overlapped, the corresponding CID is searched and attached on the corresponding VC buffer. The AAL2 CPS-PH is processed. A transmitting VCI-CID value being mapped to the received VCI-CID is calculated. The CPS-PH is completed using the transmitted VCI-CID value. It is periodically checked whether a timer value is expired by a global timer with respect to a VC buffer. A transmitting of a cell is prepared in the case that a time is expired or the VC buffer becomes full by checking the status of a build-up of a VC buffer whenever one CPS-PK is appended. If a cell to be transmitted is prepared, the STF and the ATM header are completed. The completed ATM cells are stored in an output buffer for a transmission.

Abstract: PURPOSE: An air conditioner is provided to be used for individual use by miniaturizing an air conditioner and concentrically cooling or heating the surrounding of a user. CONSTITUTION: An air conditioner for individual use is prepared by mounting a lower heat exchanger(30) on a base plate(70), attaching a thermoelectric module(10) on the lower heat exchanger, mounting a blower case(40) having a blower fan and a drive motor on the thermoelectric module, and mounting a discharge duct(50) in the upper end of the blower case. An upper ceramic plate(11) of the thermoelectric module is grounded with an upper heat exchanger(20) while a lower ceramic plate(12) is grounded with the lower heat exchanger. The upper and lower heat exchangers are formed by uprightly arranging many metal plates for increase of heat exchange amount. The thermoelectric module absorbs heat from one ceramic plate and discharges the heat via the other ceramic plate. Upon sucking air through the upper heat exchanger, the upper heat exchangers absorbs heat of the air to cool the air. The cooled air is discharged to the discharge duct through a hole in an upper face of the blower case via the blower fan. The discharge duct is adjusted in a desired direction via a venturi tube(51) formed between ducts. By controlling a flow velocity control unit(52) formed in the end of the discharge duct, an airflow of a desired flow velocity is obtained. By using a small thermoelectric module, size of an air conditioner is varied. Additionally, the surrounding of an individual is cooled or heated concentrically.
