  • Patent number: 11416766
    Abstract: In an approach to detecting the transmission of messages, analyzing said messages, calculating a message risk score and transmitting a warning notification, one or more computer processors detect transmission of a message from a user to a selected recipient. The one or more computer processors extract message information from the detected message. The one or more computer processors retrieve one or more historical conversations between the user and the selected recipient of the detected message. The one or more computer processors determine a risk score corresponding to sending the detected message to the selected recipient based on applying the extracted message information and the retrieved historical conversations to a cognitive model.

  • Patent number: 11415457
    Abstract: The present invention provides a vibration sensor, which comprises a circuit board having an accommodating space. A sensing assembly is disposed in the accommodating space. A recess for magnet sliding is disposed in the sensing assembly. Dispose a magnet in the recess and then dispose a coil layer on an arbitrary side or both sides of the sensing assembly. Furthermore, a lubricating layer is coated on the recess. Alternatively, the recess can be a vacuum structure or a hollow cross-sectional structure for reducing the friction between the recess and the magnet. Alternatively, the coil layer can be coated with a protective layer or multiple layers can be stacked. Without increasing the area of the sensor, the sensing on the variation of magnetic flux can be improved. Accordingly, the vibration sensor according to the present invention can achieve wideband detection of vibrations.
