  • Patent number: 12195063
    Abstract: The present disclosure discloses a method for positioning an auxiliary transportation vehicle in a coal mine and a positioning system thereof. The method comprises: acquiring a rotation velocity of each wheels and a rotation angle of a steering wheel, constructing a kinematics model based on wheels not for steering of the vehicle and a kinematics model based on wheels for steering of the vehicle respectively, and constructing a kinematics model based on a geometric center of the vehicle according to the above two kinematics models; and according to a travelling condition of the vehicle, integrating the kinematics model based on the geometric center with a strap-down inertial navigation system for positioning, when the vehicle is in a normal travelling state; and integrating, the kinematics model based on the wheels not for steering with the strap-down inertial navigation system for positioning, when the vehicle is in an abnormal travelling state.

  • Publication number: 20200303555
    Abstract: An electronic device includes a first electrode, and a second electrode spaced apart from the first electrode. The electronic device further includes a conduction channel in electrical connection with the first and second electrodes so as to be able to conduct a charge carrier current between the first and second electrodes along a condition path during an operating condition. The conduction channel has a gradient semiconductor oxide composition transverse to the conduction path such that the gradient semiconductor oxide composition varies from indium rich to gallium rich.
