Abstract:
A method includes acquiring multiple pieces of first received signal quality information at a receiver, where the multiple pieces of first received signal quality information represent qualities of signals received at the receiver, generating first conditional sample statistical values based on the multiple pieces of first received signal quality information and phase shift arrays corresponding to the signals, determining the first phase shift array that meets a communication requirement according to the first conditional sample statistical values, where the first phase shift array includes the phase shift value for at least one reflective element of an IRS, and configuring the IRS based on the first phase shift array.
Abstract:
This application provides a camera module and an electronic device, to reduce manufacturing costs of the camera module and improve reliability of the camera module on the premise of ensuring optical image stabilization and auto-focus functions. The camera module includes a housing, and a light transfer part, a lens group, an image sensor, and a motor disposed in the housing. The image sensor is located on the side of the light output side. The motor includes a bracket, a carrier, and eight wires. Two ends of the wires are respectively connected to the carrier and the bracket, and the wires are retractable in length. The carrier is suspended from the bracket using the eight wires and is configured to carry the lens group, and, when the wires extend or retracts in length, drive the lens group to translate or rotate.
Abstract:
This application provides a triple camera device and a terminal device. The triple camera device includes a first camera, a second camera, and a third camera. A third motor in the third camera is disposed between a first motor in the first camera and a second motor in the second camera, to avoid magnetic interference between the first motor and the second motor. In addition, a distance between two magnets that are closest to each other and that are respectively in N second magnets in the second motor and third magnets in the third motor is greater than or equal to a first preset threshold. This reduces magnetic interference between the second motor and the third motor.
Abstract:
A method for selecting an audio track from an audio and video file. The method includes: selecting one or more audio tracks that support decoding from one or more audio tracks of the audio and video file; selecting an audio track matching a language from the audio tracks that support decoding; selecting an audio track whose supported audio format is an audio format with a first specification from a plurality of audio tracks; selecting an audio track having a first bit rate from the audio track whose supported audio format is the audio format with the first specification; and playing the audio and video file. The first specification of the supported audio format is higher than a second specification of the supported audio format.
Abstract:
An enclosure of a mobile terminal and a sputter coating apparatus for making the same are provided. The enclosure includes a substrate and a composite film layer coated onto the substrate. The composite film layer has a thickness changing along a first direction. A difference in thickness between any two regions arranged along the first direction of the composite film layer is less than or equal to 350 nanometers. The enclosure has a spatially varying color corresponding to a wavelength between 400 nanometers and 760 nanometers.
Abstract:
Embodiments of the present invention relate to a content delivery method and apparatus, and an access network device. The method includes: receiving, by a cache server in an access network, a service request sent by a user equipment, where the service request contains an address of a content server; if the service data requested by the user equipment is stored, sending the stored service data to the user equipment, modifying the address of the content server in the received service request into an address of the cache server, and sending the modified service request to a core network device; receiving the modified service request that is routed by the core network device to the cache server; and sending the stored service data to the cache server through the Internet, the core network device, and the access network device, and discarding, by the cache server, the service data.
