  • Patent number: 11575632
    Abstract: Software for online active learning receives content posted to an online stream at a website. The software converts the content into an elemental representation and inputs the elemental representation into a probit model to obtain a predictive probability that the content is abusive. The software also calculates an importance weight based on the elemental representation. And the software updates the probit model using the content, the importance weight, and an acquired label if a condition is met. The condition depends on an instrumental distribution. The software removes the content from the online stream if a condition is met. The condition depends on the predictive probability, if an acquired label is unavailable.

  • Patent number: 11529719
    Abstract: A bolt clamping force transducer for a bolt tightening operation is introduced to tighten a bolted joint by driving a torque rotating shaft in a clamping force transducer, such that a helical mechanism at one end of the torque rotating shaft generates an axial force for pressing a force sensing module and thus generates a strain value thereof. A socket is driven by the other end of the torque rotating shaft, thereby generating a clamping force under which the bolted joint of a specific specification is tightened. A parameter relation between the strain value and the clamping force is calibrated with a standard axial force gauge to facilitate calculation and control of the clamping force during the tightening process where the bolted joint fitted to any torque tool is sensed to control the precision of the clamping force being exerted on the bolted joint, thereby enhancing the quality thereof.
