Abstract: A virtual wall system is composed of a mobile robotic device and at least one virtual wall generator. The mobile robotic device includes a steering unit for steering itself toward at least one direction, a steering control unit connected with the steering unit for controlling the steering of the steering unit, and at least one sonic receiver mounted to one side thereof for receiving sonic signals. The at least one virtual wall system generator is placed on a planar surface where the mobile robotic device moves, having a sonic emitter and a taper-shaped hole facing sidewards. The taper-shaped hole increasingly expands from inside out. The sonic emitter is to emit sonic signals that are directive subject to the taper-shaped hole. The at least one virtual wall system generator further includes a power module as power supply.

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 household self-contained power supply combined with, what a civil residence has equipped, a panel board, a mains power supply line, and a plurality of sockets. The panel board includes a plurality of breakers. The household self-contained power supply is composed of a power line network module, a battery unit, a control unit, an automatic changeover switch, and a plurality of adaptors. Each of the adaptors includes a sub-plug, at least one sub-socket, an electrically-controlled switch, and a sub-power-line network module. The mains power supply line is connected with the power line network module, such that the electrically-controlled switch can be controlled by the control unit to control the conduction status between the sub-plugs and the sub-sockets. Therefore, it provides a self-contained power source and self-management thereof.

Abstract: A mobile robotic device includes a frame body having a receiving recession recessed inward therefrom and a guide pusher formed thereon and extending toward the receiving recession and having a bevel formed at its one side; a dust-collecting box detachably mounted in the receiving recession and having an opening formed at one side thereof and an indentation formed at the same side as the opening for receiving the guide pusher while the dust-collecting box is inserted into the receiving recession; and a sealing member pivotably mounted to the dust-collecting box to seal the opening. Accordingly, while the dust-collecting box is drawn from the receiving recession, the sealing member can seal the opening to prevent the dust from escaping from the dust-collecting box.

Abstract: A multi-port jack assembly adapted for power transformers for computers includes a main body. The main body has a plurality of convex connection ports for electrical connection with the power transformers, an electric wire electrically connected with an end of the main body, and a plug electrically connected with a distal end of the electric wire. Thus, the present invention is connectable with the multiple transformers adapted for the computers to enable one-to-multiplicity connection and to further reduce the number of the electric wires.

Abstract: A virtual wall system includes a mobile robotic device having a steering unit for steering itself, a steering control unit connected with the steering unit for controlling the steering of the steering unit, at least one signal transmitter mounted thereon for emitting a signal, and a sonic receiver for receiving a sonic signal; and a virtual wall generator having at least one signal receiver for receiving the signal, at least one sonic transmitter for emitting a sonic signal, and a signal controller for identifying the signal and controlling the emission of the sonic transmitter. While the mobile robotic device is moving, the signal controller controls the sonic transmitter to emit the sonic signal after the signal receiver receives the signal emitted by the signal transmitter and then the sonic receiver receives the sonic signal, enabling the steering control unit to control the steering unit to steer the mobile robotic device.
