The array substrate includes a plurality of sub-pixels; wherein a storage capacitor and an extended storage capacitor are disposed in each of the plurality of sub-pixels, the extended storage capacitor and the storage capacitor being connected in parallel; and the array substrate includes a gate electrode layer, a source and drain electrode layer, and a pixel electrode.

Abstract: A method for monitoring and analyzing large tunnel machines based on automatic collection of big data includes the following steps: dividing a tunnel operation area, obtaining environmental information of a tunnel operation sub-area, analyzing rock drilling difficulty of the tunnel operation sub-area, confirming a tunnel operation trajectory, analyzing conformity of the tunnel operation sub-area, processing an abnormal tunnel operation sub-area, and analyzing health state of a tunnel rock drill. According to the present disclosure, a rock drilling difficulty coefficient of each tunnel operation sub-area is used to analyze a corresponding steel rotating speed, and then the tunnel operation trajectory is confirmed. After the tunnel operation is completed, the operation conformity of each tunnel operation sub-area is analyzed, and each abnormal tunnel operation sub-area is screened out and processed accordingly.

Abstract: The present invention relates to the technical field of central processing units (CPUs), and in particular to a fault-tolerant system with multi-core CPUs capable of being dynamically configured. The multi-core CPUs are three reconfigurable CPUs, the fault-tolerant system with multi-core CPUs is statically configured to be in a normal fault-tolerant mode, a reliable fault-tolerant mode or a performance mode by means of configuration of the three CPUs and then is switched between the normal fault-tolerant mode, the reliable fault-tolerant mode and the performance mode according to a mode switching command of a mode switching register, and finally, the three CPUs are correspondingly configured according to the mode to be switched.

Abstract: A method of determining a position of a rotor of a brushless permanent magnet motor includes measuring a current value indicative of current flowing through a phase winding of the motor and providing a reference voltage value indicative of a voltage applied to the phase winding of the motor. The method includes calculating a phase of back EMF induced in the phase winding using the measured current value and the reference voltage value, and determining a zero-crossing point of the back EMF induced in the phase winding using the calculated phase of back EMF induced in the phase winding. The method includes generating a rotor position signal based on the determined zero-crossing point.
