  • Patent number: 11466388
    Abstract: A washing machine includes a case; a tub; a drum; a vibration sensor provided in the tub and configured to output a factor of a current vibration result for sensing a vibration value of the tub; a motor configured to drive the drum to process laundry; a motor control module configured to control a drum RPM to reflect a request RPM by controlling a current of the motor and output a current vibration inducing factor; an AI module configured to receive inputs of the current vibration result factor and the vibration inducing factor and output a compensating variable for proactively deal with a future vibration result that is expected based on a current laundry distribution state, in a dry-spin cycle; and a processor configured to perform a dry-spin cycle through centrifugal power of the drum by compensating the request RPM by reflecting the compensating variable in a vibration expectation section.

  • Patent number: 10957315
    Abstract: Provided are a mobile terminal including an artificial intelligent agent and a method for controlling a mobile terminal using machine learning. A mobile terminal comprises a microphone, a learning data unit configured to identify and store keywords and a controller configured to: activate the microphone in response to an activation event, receive a voice input via the microphone, extract vocabulary information from the received voice input and execute a control corresponding to command information included in the received voice input, wherein the executed control is varied by utilizing the keywords and the extracted vocabulary information.

  • Publication number: 20070016265
    Abstract: Disclosed are methods and systems for a virtual reality simulation and display of limb movement that facilitate the development and fitting of prosthetic control of a paralyzed or artificial limb. The user generates command signals that are then processed by the control system. The output of the control system drives a physics-based simulation of the limb that simulates the limb to be controlled. The computed movements of the model limb are displayed to the user as a 3D animation from the perspective of the user so as to give the impression that the user is watching the actual movements of his/her own limb. The user learns to adjust his/her command signals to perform tasks successfully with the virtual limb. Alternatively or additionally, the errors produced by the virtual limb and/or the responses of the user during the training process can provide information for adapting the properties of the control system itself.
