  • Patent number: 10823918
    Abstract: A method and system connects multiple cores within one fiber, e.g., a multi-core fiber (MCF), to multiple fibers with single-cores. The single-core fibers can then be terminated by traditional envelopes, such as a single core LC envelope. A connector holds the single-core fibers into a pattern that matches a pattern of all, or a sub group, of the individual cores of the MCF. The single-core fibers may all be terminated to individual connectors to form a fanout or breakout cable. Alternatively, the single-core fibers may extend to another connector wherein the single-core fibers are regrouped into a pattern to mate with the cores of another MCF, hence forming a jumper. One or more of the single core fibers may be terminated along the length of the jumper to form a jumper with one or more tap accesses.

  • Patent number: 9946002
    Abstract: An electrical device includes a circuit board (101), a light source (104), and a light guide (105). The light guide receives light from the light source and conducts the received light to an end of the light guide so that the light crosses, in a direction parallel with the circuit board, an edge of the circuit board. The end of the light guide constitutes a display surface for showing the light to a user. On a fringe area extending from the edge of the circuit board a distance (D) towards the opposite edge of the circuit board, the light guide is between geometrical planes parallel and coinciding with surfaces of the circuit board. Hence, the light guide does not require room in directions perpendicular to the circuit board. Therefore, for example, more connectors, key buttons, and/or other instruments can be placed on a control panel of the electrical device.

  • Patent number: 9927614
    Abstract: A near-eye optical display system that may be utilized in augmented reality applications and devices includes a diffractive waveguide having diffractive optical elements (DOEs) configured for in-coupling, exit pupil expansion, and out-coupling. An electrically-modulated tunable liquid crystal (LC) lens is located between the diffractive grating and the eyes of the user. A polarizing filter is located on the other side of the diffractive grating so that light from the real world enters the system with a particular polarization state, for example, TM-polarized. The tunable LC lens is configured to impart variable focus on light that has an opposite polarization state, for example TE-polarized. The optical display system is arranged to be polarization-sensitive so that virtual images from an imager are out-coupled from the diffractive waveguide with TE-polarization. The tunable LC lens may thus impart variable focus to the virtual images due to the lens' sensitivity to TE-polarization.

    Abstract: A method and apparatus for non-invasively determining a concentration of glucose in a subject using optical excitation and detection is provided. The method includes emitting an exciter beam (B1) to irradiate a portion (130) of tissue of the subject, causing physical and chemical changes in the surface, and causing an initial back scattering (D1) of light. The method further includes periodically emitting a probe beam (B2) which irradiates the portion of tissue and causes periodic back scatterings (D2) of light. The initial and periodic back scatterings are detected and converted into electrical signals of at least the amplitude, frequency or decay time of the physical and chemical changes, the back scatterings being modulated by the physical and chemical changes. By differentiating over time at least one of the amplitude, frequency or decay time of the physical and chemical changes, the concentration of glucose may be determined.
