Abstract: A terminal (20) and a terminal charging method are disclosed. The terminal (20) includes a charging circuit (23), a branch selector switch (22), and a controller (21). The charging circuit (23) includes a boost charging branch (231), a direct charging branch (232), and a buck charging branch (233) connected to one another in parallel. The branch selector switch (22) is respectively connected to the boost charging branch (231), the direct charging branch (232), and the buck charging branch (233). The controller (21) is connected to the branch selector switch (22) and configured to acquire an output capability parameter of an external charger and send a switching signal to the branch selector switch (22) according to the output capability parameter, so as to enable the branch selector switch (22) to switch on one of the boost charging branch (231), the direct charging branch (232), and the buck charging branch (233).

Abstract: The present disclosure discloses an integrated weld position detection device based a binaural effect, including a microphone, a microphone holder, a megaphone, a conductive rod, and a current contact nozzle, where the microphone holder is provided with a first through hole in the center; the first through hole allows the conductive rod to pass through and is fixedly connected to the conductive rod; the current contact nozzle is fixedly connected to the conductive rod; the microphone holder is internally provided with two accommodating cavities; the two accommodating cavities are symmetrically distributed on left and right sides of the microphone holder; two microphones are respectively disposed inside the two accommodating cavities; the megaphone is provided with at least two sound transmission channels; first ends of the two sound transmission channels communicate with the two accommodating cavities respectively.

Abstract: A method and device for downloading a software version and a storage medium, including that: n partitions to be downloaded of a software version to be sent are determined, n?1 (S101); a mobile terminal is indicated to format a mapping partition corresponding to an mth partition to be downloaded in the n partitions to be downloaded in the mobile terminal, n?m?1 (S102); and when it is determined that formatting of the mapping partition corresponding to the mth partition to be downloaded is completed and succeeds, data of the mth partition to be downloaded is packed into an all-0 data packet or a non-0 data packet, and the all-0 data packet or the non-0 data packet is sent (S103).

Abstract: The disclosure discloses an image copying method, which includes the steps of: copying, an image to be copied, to a destination address line by line, in the case of the image to be copied having a width of one pixel; copying, the image to be copied, to the destination address by a number of bytes according to a size of the image to be copied, in the case of the image to be copied not having a width of one pixel. The image copying method can save the image copying time and deduce the Central Processing Unit (CPU) occupation rate.
