  • Patent number: 10500791
    Abstract: A system of this invention is a three-dimensional laminating and fabricating system that suppresses, in advance, a squeezing blade from getting caught on a surface of a laminated and fabricated object. The three-dimensional laminating and fabricating system includes a laminating and fabricating unit that includes a squeezing blade configured to spread a laminating material on an upper layer of a laminated and fabricated object, and an irradiator configured to irradiate the laminating material, and fabricates each layer of the laminated and fabricated object as an aggregate of cell regions, and a laminating and fabricating controller that controls the laminating and fabricating unit such that a scanning direction in which the irradiator irradiates the laminating material in the cell region changes with respect to a moving direction of the squeezing blade during laminating and fabricating.

  • Patent number: 10488677
    Abstract: An eye-mountable contact lens is provided that includes electronics encapsulated within a rigid, gas-permeable polymeric material. The rigid, gas-permeable polymeric material can be mountable to a corneal surface of an eye or can be disposed on or within a flexible polymeric material that is mountable to the corneal surface of the eye. The rigid, gas-permeable polymeric material can provide structural rigidity and protection to the electronics and/or can allow for long-term dry storage of a chemical sensor of the electronics. The rigid, gas-permeable polymeric materials of the provided eye-mountable devices can be formed by curing a precursor material on or around the electronics and subsequently removing portions of the polymeric material formed by the curing, e.g., to form a rigid, gas-permeable contact lens that at least partially encapsulates the electronics and that has a curved shape that is able to be mounted to a corneal surface of an eye.

  • Patent number: 10365441
    Abstract: A two-dimensional (2D) optical fiber array component takes the form of a (relatively inexpensive) fiber guide block that is mated with a precision output element. The guide block and output element are both formed to include a 2D array of through-holes that exhibit a predetermined pitch. The holes formed in the guide block are relatively larger than those in precision output element. A loading tool is used to hold a 1×N array of fibers in a fixed position that exhibits the desired pitch. The loaded tool (holding the pre-aligned 1×N array of fibers) is then inserted through the aligned combination of the guide block and output element, and the fiber array is bonded to the guide block. The tool is then removed, re-loaded, and the process continued until all of the 1×N fiber arrays are in place. By virtue of using a precision tool to load the fibers, the guide block does not have to be formed to exhibit precise through-hole dimensions, allowing for a relatively inexpensive guide block to be used.
