  • Patent number: 11955157
    Abstract: A PUF apparatus comprises: a PUF cell array in which a plurality of PUF cells are arranged each including a FeFET pair whose gates are commonly connected to a corresponding word line among a plurality of word lines, and whose drains and sources are connected to a corresponding bit line pair and a corresponding source line pair among a plurality of bit line pairs and a plurality of source line pairs running in a direction crossing the plurality of word lines; and a read-write-back block which is activated according to a read enable signal, and senses and amplifies a voltage difference occurring in a corresponding bit line pair among the plurality of bit line pairs according to the difference in driving strength due to a deviation in a manufacturing process of the FeFET pair in the PUF cell selected by a selected word line among the plurality of word lines.

  • Patent number: 11407288
    Abstract: Provided is an air vent for an automobile having a duct having a passage, a knob mount coupled to the duct, a knob installed to the knob mount, first and second vane members installed to the knob mount, a vane driving device installed to the knob mount, and a damper installed in the duct. The knob is movable leftwards and rightwards and is rotatable upwards and downwards. The first vane member is rotated upwards and downwards by the vane driving device when the knob is rotated upwards and downwards. The second vane member is rotated leftwards and rightwards by the vane driving device when the knob is moved leftwards and rightwards. The vane driving device transmits the rotation of the knob to the first vane member, and transmits the movement of the knob to the second vane member. The damper opens or closes the passage by rotation.
