The present disclosure provides a detection system whereby a virus or the like can be effectively detected in order to suppress the spread of infectious disease by the virus or the like. The detection system according to the present disclosure includes an autonomous collection device that is capable of moving on a floor surface and for collecting an object on the floor surface, and a station device for detecting an analyte from the object collected from the floor surface by the autonomous collection device. The autonomous collection device includes a moving part for moving on the floor surface, a primary electric blower for sucking the object on the floor surface, and a dust container for storing the sucked object. The station device includes a transfer pipe fluidically connected to the dust container of the autonomous collection device when the autonomous collection device is positioned in a home position, and a virus detection part for detecting the analyte from the object transferred from the dust container through the transfer pipe.

A moving device and an object detection method thereof are provided. A method, performed by a moving device, of generating a map related to an object in a task space includes radiating at least one sensing signal toward aboveground and underground regions in a vicinity of the moving device, receiving signals reflected from an aboveground object located on a ground in the task space and an underground object located under the ground in the task space, and generating the map indicating distribution of the aboveground object and distribution of the underground object, based on the received reflected signals.

A vacuum clear and an electric motor module (100) therefor are provided. The electric motor module (100) includes an outer casing (1) provided with an air inlet (10) at a front side thereof and an air outlet (11) at a rear side thereof; an electric motor assembly (2) arranged in the outer casing (1), and cooperating with the outer casing (1) to define an air passage in communication with the air inlet (10) and the air outlet (11); and a silencer (3) arranged at the air inlet (10), defining at least one resonant cavity therein, and the at least one resonant cavity having a side wall provided with a throat in communication with the resonant cavity.

A handle removably connectable to an appliance includes a battery pack. A vacuum cleaner which uses the handle and an air cooled battery charger is also provided.

The invention comprises a vacuum attachment with multiple ports which easily attaches to an open top container to remove concrete/mortar dust and particulates from the air when mixing concrete/mortar with water. The vacuum attached in configured to fit securely on a variety of containers of different sizes. Further, the vacuum attachment attaches easily to any standard vacuum machine. The vacuum attachment may have lateral segments which provide spacing for two curved portions which terminate in multiple ports. The curved portions may be positioned at the top of the container with the ports facing downward into the container. When a vacuum machine is attached and activated, the vacuum attachment is able to efficiently remove dust particles from the air inside the container. Multiple vacuum attachments may also be used simultaneously by connecting a Y splitter hose to each of the vacuum machine attachment ports of the vacuum attachments.

An evacuation station includes a base and a canister removably attached to the base. The base includes a ramp having an inclined surface for receiving a robotic cleaner having a debris bin. The ramp defines an evacuation intake opening arranged to pneumatically interface with the debris bin. The base also includes a first conduit portion pneumatically connected to the evacuation intake opening, an air mover having an inlet and an exhaust, and a particle filter pneumatically the exhaust of the air mover. The canister includes a second conduit portion arranged to pneumatically interface with the first conduit portion to form a pneumatic debris intake conduit, an exhaust conduit arranged to pneumatically connect to the inlet of the air mover when the canister is attached to the base, and a separator in pneumatic communication with the second conduit portion.

Disclosed is a dust collector using fan heat, comprising a bottom shell (10) and an upper cover (50), wherein a rear end (12) of the bottom shell (10) is provided with an air outlet (122) and a fan assembly (30), the upper cover (50) covers and is connected to the bottom shell (10), air flow from the fan assembly (30) is discharged via the air outlet (122), and the fan assembly (30) is provided with a fan (33) and a stator (331); and the rear end (12) is provided with a lower frame edge (121), the fan assembly (30) and the air outlet (122) are enclosed to form a closed air flow channel (35), and a heat collector (40) is provided on the stator (331) in the air flow channel (35), and can rapidly collect heat and warm the air flow to form hot air flow. Also disclosed is a dust collector having an ironing function, which uses hot air flow to heat an ironing board (60) and then performs ironing and sterilization, so that the dust collector also implements recycling of energy resources while achieving the dust collection effect so as to perform effective sterilization and ironing.

Disclosed are a robot cleaner, a refrigerator, a container transfer system, and a method of transferring and retrieving a container using the robot cleaner. The method of transferring a container include returning a robot cleaner to a position guide device installed at a refrigerator, mounting the robot cleaner on the position guide device, transferring, by the refrigerator, a container built in the refrigerator to mount the container on the robot cleaner, and moving the robot cleaner on which the container is mounted to a target position.

An evacuation station includes a base and a canister removably attached to the base. The base includes a ramp having an inclined surface for receiving a robotic cleaner having a debris bin. The ramp defines an evacuation intake opening arranged to pneumatically interface with the debris bin. The base also includes a first conduit portion pneumatically connected to the evacuation intake opening, an air mover having an inlet and an exhaust, and a particle filter pneumatically the exhaust of the air mover. The canister includes a second conduit portion arranged to pneumatically interface with the first conduit portion to form a pneumatic debris intake conduit, an exhaust conduit arranged to pneumatically connect to the inlet of the air mover when the canister is attached to the base, and a separator in pneumatic communication with the second conduit portion.

A robot for detecting a dangerous situation using artificial intelligence includes a memory configured to store a voice recognition model for inferring whether a current situation is the dangerous situation from voice data and an image recognition model for inferring whether the current situation is the dangerous situation from image data, and a processor configured to acquire one or more of the voice data or the image data and output a notification indicating the dangerous situation when the dangerous situation is detected from the voice data using the voice recognition model or when the dangerous situation is detected from the image data using the image recognition model.
