  • Patent number: 10800153
    Abstract: A three-dimensional object may be generated. First and second agent distributors may be to respectively selectively deliver a binder agent and a coalescing agent onto portions of a layer of build material. A controller may be to control the first and second agent distributors to respectively selectively deliver the binder agent and the coalescing agent onto respective first and second portions of the layer in patterns derived from data representing a slice of the three-dimensional object to be generated. The first portion having the binder agent may be to bind and solidify into a binder matrix. When energy is applied to the layer the second portion having the second agent may be to coalesce and solidify.

  • Publication number: 20170146748
    Abstract: A unitary multi-fiber ferrule has micro-holes for optical fibers, an optical stop plane for the optical fibers, and a plurality of lenses disposed adjacent the front end, each of the plurality of lenses optically aligned with one of the micro-holes and exposed to air. Multiple rows of optical fibers and lenses may also be used in the unitary multi-fiber ferrule. The unitary multi-fiber ferrule requires less processing and equipment than other current optical ferrules.

  • Patent number: 9122022
    Abstract: A fiber optic connector has a connector outer housing and a connector inner housing. The connector inner housing has a projection to interact with a latch on an adapter into which the connector is inserted. The force required to move the connector outer housing relative to the connector inner housing is less than the force to remove the connector inner housing from the latch. A groove or opening may also be formed in the connector outer housing to effectively shorten the connector outer housing and prevent interaction of the latch with the outer housing, reducing debris.

  • Patent number: 7841777
    Abstract: An adapter with a dust shutter also provides eye protection and an even seal around the connector opening. The adapter includes a main body, a cover, and a resilient member to bias the cover in a closed position. The adapter also includes a flexible member to assist in sealing the adapter. The resilient member contacts the cover in a center portion and the cover floats relative to the main body to ensure a good seal.

  • Publication number: 20070297726
    Abstract: A ferrule has at least one row of optical fiber openings to hold optical fibers. The ferrule also includes a lead-in portion for each of the optical fiber openings to assist in positioning the optical fibers into the optical fiber openings in the ferrule. The optical fiber openings in the ferrule are slightly smaller and have a similar spacing allowing for better fill between the optical fiber openings. A mold core that corresponds to the ferrule is disclosed. The mold core encapsulates at least a portion of the optical fiber opening forming pins, eliminating build up and breakage of the pins.

  • Patent number: 6821028
    Abstract: An interface system includes separate optical and mechanical interfaces between opto-electronic devices and fibers. This allows each of these components to be optimized for their particular function. The mechanical interface includes an aperture through which light is transmitted between the fibers and optical element on the optical interface. Protruding features on the optical interface mate with the aperture in the mechanical interface to align the optics block with the mechanical interface.
