  • Publication number: 20240012226
    Abstract: A camera lens including a first lens, a prism, and a plurality of lenses. The first lens has positive focal power, and an object-side surface of the first lens is a convex surface. An object-side surface of the prism is in contact with an image-side surface of the first lens. The prism refracts, from a first optical axis to a second optical axis intersecting the first optical axis, light received from the first lens. The plurality of lenses include at least three lenses, and the plurality of lenses are sequentially disposed along the second optical axis.

  • Publication number: 20230185063
    Abstract: This application provides an optical lens, a camera module, and an electronic device. The optical lens includes a first lens, a second lens, a third lens, a fourth lens, a fifth lens, and a sixth lens that are sequentially arranged from an object side to an image side. The first lens, the third lens, and the fifth lens all have positive focal power, the second lens and the fourth lens both have negative focal power, and the sixth lens has positive focal power or negative focal power. Object side surfaces and image side surfaces of the first lens to the sixth lens include at least one anamorphic aspherical surface. When the optical lens is applied to the camera module and the electronic device, the camera module and the electronic device can implement ultra-wide-angle photographing, and can also resolve a distortion problem in ultra-wide-angle imaging to a large degree.

  • Publication number: 20220188477
    Abstract: The present invention relates to an optimal load curtailment calculating method based on Lagrange multiplier and an application thereof in power system reliability assessment, wherein the calculating method comprises the following steps: inputting all system states to be analyzed for reliability assessment and establishing corresponding optimal load curtailment models; classifying the optimal load curtailment models according to Lagrange multiplier to obtain several sets; and solving the optimal load curtailment models in each set by using Lagrange multipliers to obtain an optimal load curtailment corresponding to the system state. The core of the present invention is to establish Lagrange-multiplier-based linear functions between the optimal load curtailment and the system states, and the iterative optimization processes of the traditional optimal load curtailment calculating method are substituted with the simple matrix multiplications.
