摘要： The disclosed embodiments describe a method, apparatus, and system for pushing information. In one embodiment, the method comprises: receiving dynamic spatio-temporal behavior data of a moving individual; conducting an analysis according to historical dynamic spatio-temporal behavior data of the moving individual to acquire spatio-temporal behavioral characteristics of the moving individual; determining appropriate information as matching information for the moving individual according to the spatio-temporal behavioral characteristics of the moving individual in combination with dynamic spatio-temporal behavior data of the moving individual at a current time; and sending the matching information to the moving individual. In the method of the disclosure, behavioral characteristics of a moving individual are analyzed to obtain habit and preference characteristics of the moving individual. Targeted push information is sent, thereby solving the problem of pushed information having less diversified, targeted, and not so accurate content.

摘要： An imaging lens includes a lens barrel, a plurality of lens elements and a spacer. The lens elements are disposed in the lens barrel. The spacer is disposed between the lens barrel and one of the lens elements or between two adjacent lens elements. The spacer is ring-shaped and includes an inside layer and two outside layers. The two outside layers are attached on opposite sides of the inside layer, respectively. The spacer has an object-side surface, an image-side surface and a first inner ring-shaped oblique surface. The object-side surface and the image-side surface are formed outside the two outside layers in parallel and oriented toward an object side and an image side of the lens elements, respectively. The first inner ring-shaped oblique surface is formed at an inner periphery of the spacer and connected to at least one of the object-side surface and the image-side surface.
