An access control method and apparatus for a user equipment relate to the field of communications technologies. In embodiments, the saliency of pixels in the set of images is determined using one or more image features. For each content unit being transferred, the server may maintain a count of the aggregate size of buffers for transferring content of that content unit. The all-solid planar sensor cell has two or more film type electrodes arranged on a non-conductive planar surface of a supportive substrate. The process for cutting such a brittle-material plate includes a first step for forming a scribe line L2 on a top surface G1 of the plate G, and a second step for relatively moving the irradiation position A of the laser beam on the top surface G1 of the plate G along the scribe line L2 to cut the plate ahead of the irradiation position in the moving direction of the plate. The application may include modules for rendering a 3-D image, moving within a virtual 3-D environment, and editing the document.
