  • Publication number: 20240252309
    Abstract: A double-sided aspheric diffractive multifocal lens and methods of manufacturing and design of such lenses in the field of ophthalmology. The lens can include an optic comprising an aspheric anterior surface and an aspheric posterior surface. On one of the two surfaces a plurality of concentric diffractive multifocal zones can be designed. The other surface can include a toric component. The double-sided aspheric surface design results in improvement of the modulation transfer function (MTF) of the lens-eye combination by aberration reduction and vision contrast enhancement as compared to one-sided aspheric lens. The surface having a plurality of concentric diffractive multifocal zones produces a near focus, an intermediate focus, and a distance focus.

  • Patent number: 12052841
    Abstract: A server includes a first server unit, a second server unit, a hinge and a connecting element. The second server unit is disposed on the first server unit and is electrically connected to the first server unit. The second server unit is pivoted to the first server unit through the hinge. The connecting element is disposed between the first server unit and the second server unit. The connecting element has a first connection end and a second connection end, wherein the first connection end is connected to the first server unit, and the second connection end is connected to the second server unit. A server system including a rack and at least one server is also provided.
