  • Publication number: 20240331742
    Abstract: A calibration device is coupled to a communication line shared by plural devices. The calibration device is configured to perform an iterative eye width scanning by adjusting a set voltage level by a preset level from a first voltage level to a reference center voltage level, wherein the first voltage level corresponds to a cross point where values of signals or data, which are transmitted via the communication lines, are changed in different directions; and determine, as a zero crossing for the signals or the data, a voltage level corresponding to a largest value among a plurality of eye widths obtained through the iterative eye width scanning.

  • Patent number: 12037646
    Abstract: A function of cyclin-dependent kinase 12 (CDK12) as a biomarker for a human epidermal growth factor receptor 2 (HER2)-positive cancer and anti-HER2 therapy, and a use of the CDK12 are provided. The CDK12 may be used for companion diagnostics of a HER2-targeted therapeutic agent for a subject having HER2+ cancer as a prognostic factor and a predictive factor for response of the subject to the anti-HER2-targeted therapeutic agent in HER2+ cancer, or used to check the probability of expressing resistance to the HER2-targeted therapeutic agent. When the CDK12 is amplified or expressed at a level higher than a reference value, the CDK12 may be suppressed to overcome the resistance to the HER2 therapeutic agent and improve a therapeutic effect, thereby improving the therapeutic efficiency of HER2-positive cancer.

  • Patent number: 8873832
    Abstract: The present invention relates to a slip detection apparatus and method for a mobile robot, and more particularly, to a slip detection apparatus and method for a mobile robot, which not only use a plurality of rotation detection sensors to detect a lateral slip angle and lateral slip direction, but also analyze the amount of change in an image and detect the blocked degree of an image input unit to determine the quality of an input image, and detect the occurrence of a frontal slip to precisely detect the type of slip, direction of the slip, and the rotation angle, and, on the basis of the latter, to enable the mobile robot to move away from and avoid slip regions, and to reassume the precise position thereof.

  • Patent number: 8849036
    Abstract: The present invention relates to a map generating and updating method for mobile robot position recognition, and more specifically relates to a map generating and updating method for mobile robot position recognition, whereby position recognition error can be minimized by registering landmarks extracted during map generation and landmarks extracted on the basis of the probable error in inferred landmarks, calculating the accuracy of landmarks pre-registered during map generation, and adjusting the level of landmarks of low accuracy or removing landmarks which have been registered erroneously.

  • Patent number: 8744665
    Abstract: The present invention relates to a control method for the localization and navigation of a mobile robot and a mobile robot using the same. More specifically, the localization and navigation of a mobile robot are controlled using inertial sensors and images, wherein local direction descriptors are employed, the mobile robot is changed in the driving mode thereof according to the conditions of the mobile robot, and errors in localization may be minimized.
