Abstract: A rotary compressor provided that may include a casing, a cylinder, a roller, and at least one vane slidably inserted into the roller, and the roller may have at least one bypass passage through which spaces on both sides of a contact point based on a rotational direction of the roller communicate with each other. Through the at least one bypass passage, residual refrigerant remaining in a compression space even after a discharge stroke may be bypassed to a suction chamber, thereby minimizing the refrigerant remaining in the compression space after the discharge stroke. Also, loss due to overcompression in a residual space may be suppressed or prevented while reducing suction loss due to the introduction of overcompressed high-pressure refrigerant by the bypassing the refrigerant in the residual space toward a suction side in advance.

Abstract: A method and apparatus for identifying change sequence information in a wireless LAN system are proposed. In detail, an STA receives a DTIM beacon frame and a beacon frame from a first AP. The STA decodes the DTIM beacon frame in a first awake state and decodes the beacon frame in a second awake state. Both the DTIM beacon frame and the beacon frame include a CUF and a CSN. When a significant update of a second AP occurs, a value of the CUF is changed from 0 to 1 until transmission of a next DTIM beacon frame, the value of the CUF is changed from 1 to 0 after the transmission of the next DTIM beacon frame, and the CSN includes updated information. The updated information is decoded in the second awake state regardless of the value of the CUF.
