  • Publication number: 20210310693
    Abstract: Disclosed herein is an air conditioner including a suction panel which includes a suction port through which air is suctioned in inside a housing. The suction panel is formed to rotate with an axial direction of an air blowing fan or a direction perpendicular to the axial direction of the air blowing fan as a rotation axis to be coupled with or separated from the housing. Accordingly, a user may easily and intuitively separate the suction panel and falling of the suction panel, which may occur when the suction panel is separated, may be effectively reduced using a supporting unit disposed at the suction panel. Also, the housing and cover members which cover an outer perimeter of a lower portion of the housing may be coupled with each other by pressurizing the cover members toward the housing, thereby allowing the user to easily coupled the cover members.

  • Patent number: 10983164
    Abstract: A test apparatus may include transceivers and a global de-skew circuit. In a training mode, the transceivers provide first timing information obtained by delaying a first data signal in the range of up to a preset unit interval based on a clock signal and receive second timing information corresponding to timing differences between a slowest transceiver and the remaining transceivers. In an operation mode, the transceivers provide compensation data to a plurality of DUTs (Devices Under Test) substantially simultaneously. The compensation data may be obtained by delaying a second data signal by multiples of the preset unit interval in response to the second timing information. In the training mode, the global de-skew circuit receives the first timing information, calculates, using the first timing information, the timing differences between the slowest transceiver and the remaining transceivers, and provides the second timing information corresponding to the timing differences to the transceivers.
