Abstract: A terminal is disclosed, wherein a metal back cover of the terminal includes a slot. The slot divides the metal back cover into two parts. One of the two parts is used as an antenna radiator. The antenna radiator includes a signal feed point, a first ground point, and at least one second ground point, so that an antenna of the terminal has four resonance points. The signal feed point is connected to a matching network, the first ground point is grounded by a switch device, and the second ground point is grounded. A distance between the signal feed point and the first ground point is less than a distance between the signal feed point and the second ground point, and none of the signal feed point, the first ground point, and the second ground point is located in an end of the slot.

Abstract: A method for improving fault tolerance of a touchscreen determines an abnormal node, and shield the abnormal node to improve the fault tolerance of the touchscreen. The method includes detecting a capacitance value of each node in the touchscreen, comparing the detected capacitance value of each node with a preset capacitance value of each node to determine N target nodes, where N is an integer greater than or equal to zero, and the target nodes are nodes whose capacitance values vary, determining whether an abnormal node is included in the N target nodes, where the abnormal node is a target node determined when no touch operation occurs on the touchscreen, and discarding a row value, a column value, and a capacitance variation value of the abnormal node when the abnormal node is included in the N target nodes.

Abstract: A storage device may be used in a neural network. The storage device includes a memristor unit, a current-controlled circuit, and a write circuit. The memristor unit has a structure of one-transistor and one-resistive random access memory (1T1R). The current-controlled circuit is configured to limit a current passing through the memristor unit to a target current, where the target current is determined based on target conductance of the memristor unit and a gate voltage of the transistor, and the target conductance is used to indicate target data to be written into the memristor unit. The write circuit is configured to load a write voltage to the memristor unit in cooperation with the current-controlled circuit, to write the target data to the memristor unit.

Abstract: An electronic device includes a substrate and an antenna apparatus. The substrate includes a grounding area. The antenna apparatus includes a first radiating element, a second radiating element, a third radiating element, a first feeding structure, and a second feeding structure that are disposed in the clearance area adjacent to the grounding area. The first radiating element and the grounding area jointly form a slot antenna. The second radiating element is separated from the grounding area. The first feeding structure and the second feeding structure are located at the clearance area and are grounded. The second feeding structure is electrically coupled between the third radiating element and the ground. The antenna apparatus feeds a radiating element using the first feeding structure and the second feeding structure to obtain resonance modes at different frequencies, thereby implementing a dual-band dual-antenna function.
