  • Patent number: 10991537
    Abstract: A vertical vacuum transistor with a sharp tip structure, and associated fabrication process, is provided that is compatible with current vertical CMOS fabrication processing. The resulting vertical vacuum channel transistor advantageously provides improved operational characteristics including a higher operating frequency, a higher power output, and a higher operating temperature while at the same time providing a higher density of vertical transistor devices during the manufacturing process.

  • Publication number: 20200398800
    Abstract: A vehicle control apparatus and a method for controlling the same are disclosed. The vehicle control apparatus includes an inputter, a determiner, and a controller. The inputter receives an automatic vehicle hold (AVH) switch operation signal from an AVH device, and receives a current vehicle movement value sensed by a sensing device and a current vehicle brake force value of a brake device that generates brake force in response to activation of the AVH device. The determiner determines whether the received AVH switch operation signal transitions from an ON state to an AVH entry state, determines whether vehicle movement occurs on the basis of the received current vehicle movement value during an AVH retention time in the AVH entry state, and determines that the current vehicle brake force value is in an abnormal state when vehicle movement occurs. The controller receives the current vehicle movement value and the current vehicle brake force value, and transmits a command for judgment to the determiner.

  • Patent number: 8894117
    Abstract: A robot finger driving module is driven by a driving motor installed in a robot hand. The robot finger driving module receives a driving force of the driving motor by a pulley gear connected to the driving motor through a driving belt. When the robot finger driving module is fixed, a driving direction of a first output gear is opposite to a rotation-driving direction of a second output gear. When the robot finger driving module rotates, even though any one of the first output gear and the second output gear is fixed, the other is driven to rotate in the rotating direction of the robot finger driving module, thereby exhibiting differential gear characteristics.
