  • Publication number: 20240145143
    Abstract: Provided are a magnetic actuation device using a permanent magnet which may generate a magnetic field for a long time with lower power and lower heat by using the permanent magnet, and a system using the same. The magnetic actuation device may utilize the plurality of permanent magnets for controlling an alignment direction with two degrees of freedom to thus exclude an actuation element limiting space utilization, such as a robot arm, thus allowing an operator using a medical device to perform a safe procedure on a patient.

  • Patent number: 9013560
    Abstract: The present invention relates to a viewing range notification method for guiding a viewer to watch TV within an optimal viewing range by providing a guide message for advising the viewer to change his/her position if the viewer is out of the optimal viewing range and a TV receiver appropriate for implementing the guiding method. According to the present invention, the viewing range guiding method can be implemented by a three-dimensional TV receiver. The three-dimensional TV receiver determines whether the viewing range of the user is farther than a predetermined distance, and whether the viewing angle is within the predetermined angular range. Then, if the viewing range is nearer than the predetermined distance or the viewing angle is not within the predetermined angular range, the three-dimensional TV receiver provides a guide message for changing the viewing position.
