The invention discloses an endurance area determination method and device for vehicles. In response to an endurance area determination request, vacuation is performed on edge coordinate points of at least two determined endurance areas, whether the endurance areas are intersected is judged, as for the intersected endurance areas, edge coordinate points, falling into the other one of the two intersected endurance areas, of at least one of the endurance areas are deleted, and a to-be-output endurance area is formed by remaining edge coordinate points of each endurance area determined in responseto the endurance area determination request. In the intersected endurance areas, the edge coordinate points, falling into the other one of the two intersected endurance areas, of at least one of theendurance areas are deleted, the problem of abnormal display caused by the fact that the edge coordinate points and other edge coordinate points in the intersected endurance areas define an intersection area and the intersection area is repeatedly drawn on a map interface is solved.

The embodiment of the invention discloses an operator name acquisition method and device. The method comprises the steps that on the condition that terminal equipment successfully registers a network, an operator name which is reported by a Modem layer and corresponds to the network is received through an AP layer; if it is judged that a preset character is contained in the operator name through the AP layer, an operator name matched with the network is sought and acquired in a prestored configuration list of the AP layer. By adopting the method, the problem that the operator name corresponding to the network connected by the terminal equipment may generate display abnormality can be avoided.

The invention relates to a double-channel operational amplifier circuit which comprises a first operational amplifier and a second operational amplifier. The second operational amplifier and the first operational amplifier are operated under a half-voltage operation mode; in a first frame of time interval, the double-channel operation amplifier switches operation voltage ranges of a first input level, a first gain level and a first output level to be between a working voltage and a half-working-voltage and switches operation voltage ranges of a second input level, a second gain level and a second output level to be between the half-working-voltage and a grounding level; in the second frame of time interval, the double-channel operational amplifier switches the operation voltage range of the second input level and the second gain level to be between the working voltage and the half-working-voltage and switches the operation voltage ranges of the first input level and the first gain level between the half-working-voltage and the grounding voltage.

The present application provides a method, device, device, and computer-readable storage medium for adjusting the position of a virtual key; the method includes: presenting a key adjustment interface of a virtual scene containing a target virtual key; responding to a movement operation for the target virtual key Controlling the target virtual key to move in the key adjustment interface to adjust the presentation position of the target virtual key in the virtual scene; wherein, the presentation form of the target virtual key in the virtual scene includes at least two ; When the target virtual key moves to the boundary area in the key adjustment interface, present prompt information to prompt that when the target virtual key is in the target presentation form of the at least two presentation forms, the target The virtual keys are abnormally displayed in the virtual scene. Through the application, the memory consumption in the process of data processing can be reduced, and the data storage space can be saved.
