  • Publication number: 20240151988
    Abstract: Disclosed is a method for automatically centering an ophthalmic lens, including steps of: —positioning the ophthalmic lens on a holder; —acquiring at least one image of the ophthalmic lens received on the holder by means of a camera; and —processing the image to find the position of an optical center of the ophthalmic lens by means of a processing unit. According to the invention, the ophthalmic lens including several distinct centering markings distributed along a geometrical figure, the step of processing includes: —determining, for at least three of the centering markings, the position of at least one characterization point of each centering mark; and —deducing therefrom the position of the optical center of the ophthalmic lens.

  • Patent number: 10721871
    Abstract: A wrapping arrangement for an agricultural round baler includes a support frame and a wrapping mechanism including at least one wrap material feeder mounted on the support frame. The wrap material feeder includes a supply of wrap material. At least one wrap material clamp and cutting device is operably mounted to the wrap material feeder, and a clamp mechanism is mounted proximate to the wrap material clamp and cutting device. The clamp mechanism is adapted to clamp a free end of the wrap material by a biasing clamping force for pre-positioning the wrap material for functional operation with the wrapping mechanism.
