Abstract: A cleaning system, including a robot cleaner and a station are provided. The cleaning system includes a robot cleaner including a dust collector, the dust collector provided with a dust outlet, and an outlet door configured to open and close the dust outlet. The robot cleaner further includes a station including a lever device configured to open the outlet door and communicate with the dust collector when the lever device is pressed by the robot cleaner, and a collector configured to communicate with the lever device, and generate a suction force to suction dust collected in the dust collector.

Abstract: a memory module test system for testing a plurality of memory modules includes a plurality buffers in one-to-one correspondence the plurality of memory modules, each of the buffers including a self-test engine for testing a corresponding memory module. The test system further includes an interface configured to receive a test program for testing the memory module, and a gate array configured to transmit the test program to the buffers using a Joint Test Action Group (JTAG) protocol and to read test results of the test program from the buffers using the JTAG protocol.
