  • Patent number: 12249403
    Abstract: The disclosure provides systems and methods for conducting and managing integrated laboratory experiments. The system includes a variety of laboratory instruments that are connected to conduct a large number of different types of experiments, and an interface for a user to design experiments and adjust parameters for the experiments. Given the integration, the system can further take data from related samples and instruments for determining or adjusting certain experimental parameters for optimized experimental efficiency and results.

  • Patent number: 5452393
    Abstract: A routing device for changing the direction of a fiberoptic path from a first axis to a second axis comprising a length of optical fiber having first and second directed fiber portions aligned with the first and second axes, respectively, and having a mid-potion extending through an arc of radius of the order of 2 cm or less; the mid-portion of the fiber having been treated to have a substantially reduced diameter relative to the directed fiber portions. In certain preferred embodiments, the diameter of the mid-portion of the fiber is sufficiently reduced to achieve an air-cladded state. Preferably the routing device includes an outer member for fixing the first and second directed portions relative to one another. The mid-fiber portion is preferably reduced by etching, polishing, or drawing (e.g., differential speed unidirectional drawing). Bent sections of the fiber are thermally annealed forming stress-free bends of minimum bend radius for long term applications.

  • Patent number: 5138676
    Abstract: Bends in optical fibers can be miniaturized by reducing the diameter of a section of the fiber in the region where bending is desired to a condition in which the optical properties of the fiber have reduced bend-loss sensitivity. In one aspect of the invention, radii of curvature less than 100 microns (.mu.) and very low optical power loss are achieved. A fiber with such specially reduced diameter may also be twisted about its longitudinal axis to a greater degree than a comparable length of larger diameter fiber. Any optical fiber can be processed by redrawing and/or chemical means to allow such bending or twisting. Bend or twist tolerant regions thus formed may be packaged separately or built integrally into a wide range of fiber optic components, networks, or systems with significant space savings, added performance features and mechanical flexibility.
