An example image forming apparatus includes a main body, a driving motor, a developing cartridge, and a clutch. The developing cartridge includes a toner container, a mounting portion to receive a toner refill cartridge, a toner inlet portion to connect the mounting portion to the toner container, and a toner inlet shutter to be switched between a blocking location for blocking the toner inlet portion and an inlet location for opening the toner inlet portion. The clutch is to selectively transmit a driving force of the driving motor to the toner inlet shutter.

A method for controlling an artificial intelligent (AI) device providing a travel service, and which includes learning, via a processer of the AI device, a plurality of daily patterns related with a user's wake-up time, a commuting time, and a travel route using a deep neural networks (DNN) model; determining, via the processor, whether the daily patterns satisfy predetermined conditions each time a corresponding daily pattern among the plurality of daily patterns is generated; determining, via the processor, that the user is currently traveling when at least one daily pattern among the plurality of daily patterns that does not satisfy the predetermined conditions is detected; setting, via the processor, a time when the at least one daily pattern that does not satisfy the predetermined conditions is detected for a first time as a starting point of travel; setting, via the processor, a time from the starting point of the travel to an end point of the travel as a travel period of the user when an end of the user's travel is detected; and outputting travel information related with the travel period.

Artificial device and method for controlling the same

Disclosed herein are an artificial intelligence-based apparatus and method for providing wake-up and bed time information. The artificial intelligence-based apparatus for providing wake-up and bed time information includes a communication unit configured to receive usage information for an electronic device used by a user from the electronic device; a memory configured to store the usage information; and a processor configured to load the usage information from the memory, analyze usage time of the electronic device, extract a life pattern of the user, and predict an average wake-up or bed time of the user based on the life pattern. According to the embodiment of the present invention, it is possible to provide services for tasks which the user needs to do at the wake-up or bed time and provide convenience to the user.

Artificial intelligence-based apparatus and method for providing wake-up time and bed time information

In some examples, an apparatus can include a mating interface coupled to a dispense interface to interact with a print particle dispense nozzle, a locking mechanism coupled to the dispense interface to prevent the print particle dispense nozzle from depositing a print particle to the dispense interface, and an authentication mechanism coupled to the locking mechanism to: authenticate the print particle dispense nozzle, and unlock the locking mechanism when the print particle dispense nozzle is authenticated to allow the print particle dispense nozzle to deposit the print particle to the dispense interface.

Authentication mechanisms

A printer may include a main body and a development cartridge attachable to and detachable from the main body. The development cartridge may comprise a developing portion in which a photoconductive drum and a developing roller are provided, a waste toner container to receive waste toner removed from the photoconductive drum, a toner container connected to the developing portion and to receive toner, and a toner refilling portion connected to the toner container and to refill toner through the toner refilling portion into the toner container. The printer may include a communicating portion provided in the main body to be connected to the toner refilling portion to provide an access the toner refilling portion from outside of the main body when the development cartridge is attached to the main body.

Structure to refill toner to development cartridge mounted in main body

An example toner refill cartridge includes a body, a plunger, a weight part, and a weight part container. The body includes a toner chamber to contain toner and a toner discharging portion having an entrance connected to one end of the toner chamber in a length direction and an exit to discharge toner. The plunger includes a piston that is movably inserted into the toner chamber in the length direction and a packing member located at an end of the piston to push the toner toward the toner discharging portion. The weight part is movably accommodated in the toner chamber and has a shape that prevents the weight part from passing through the entrance. The weight part container is provided in the one end of the toner chamber in the length direction such that the weight part can be accommodated therein.
