Abstract: A multi-channel switch device is provided. The multi-channel switch device includes a first-stage switch circuit, at least one second-stage switch circuit, and multiple third-stage switch circuits. The first-stage switch circuit includes a first common-mode node, a first input/output terminal, and at least one first-stage connection terminal. The second-stage switch circuit includes a second common-mode node, a second-stage transmission terminal, and multiple second-stage connection terminals. Each of the third-stage switch circuits includes a third common-mode node, a third-stage transmission terminal, a reference terminal, and a second input/output terminal. Two of the first input/output terminal and the at least one first-stage connection terminal are connected through the first common-mode node. Two of the second-stage transmission terminal and the second-stage connection terminals are connected through the second common-mode node.

Abstract: A dust-collectable mobile robotic vacuum cleaner includes a base frame, a driving device mounted to the base frame, a control device mounted to the base frame and electrically connected with the driving device, a collision-detectable unit mounted to the base frame electrically connected with the control device, and a dust-collecting device mounted to the base frame. The dust-collecting device has dust-collecting box, a dust guider, a round brush, and a dust entrance formed at one side of the dust-collecting box. The dust guider is located at a lower edge of the dust entrance, having two opposite sides pivotably mounted to the dust-collecting box and lying against the ground at a predetermined angle respectively, for upward and downward pivoting movement. The round brush is rotatably located at a front end of the dust guider for sweeping dust particles.

Abstract: An automatic charging station for an autonomous mobile machine includes a base, a housing, and a signal transmitter. The base is mounted on the ground or on a planar surface. The housing is rotatably mounted on the base, having at least one guide member and a plurality of electrically conductive members on a surface thereof. The electrically conductive members are located on the housing. The signal transmitter is mounted on the housing for transmitting a signal. When the autonomous mobile machine senses the signal transmitted by the transmitter while moving, the autonomous mobile machine moves along a route towards the housing and then forces the guide member to enable the housing to rotate for facing and accommodating the autonomous mobile machine and to further enable the autonomous mobile machine to contact against the housing to have its electrodes in contact with the electrically conductive members for charging.

Abstract: A ratchet-based adaptor assembly is comprised of a main body, a shell, a ratchet-like driven member, a switch member, and a spring. The shell is covered on the main body, having a neck formed at a side for connection with a wheel replacement wrench. A receiving space is defined between the main body and the shell. The ratchet-like driven member is rotatably mounted in the receiving space, having a plurality of teeth and an adaptor for connection with a rotatable joint of a jack. The switch member includes at least two teeth for engaging the teeth of the ratchet-based driven member, being pivotally mounted in the receiving space but having a part exposed outside the main body for poking by the user's hand. The spring is mounted in the receiving space so as to keep enabling the switch member to engage the driven member.
