  • Patent number: 9405075
    Abstract: The present document describes an interface connector handle for connecting a first optical fiber to a second optical fiber. The first optical fiber is substantially centered within a proximal portion of a guidewire tubing. The second optical fiber is routed through and extending from an optical interface cable. The interface connector handle comprises a biasing assembly for urging one of the first optical fiber and the second optical fiber toward the other one of the first optical fiber and the second optical fiber resulting in a contact therebetween.

  • Patent number: 9405078
    Abstract: There is described a method for terminating an optical fiber within a proximal portion of a guidewire tubing. The guidewire tubing has an outside diameter and comprises a lumen. The method comprises centering the optical fiber relative to the outside diameter of the proximal portion of the guidewire tubing. The optical fiber and the inside of the lumen define an average gap there between. The average gap around the optical fiber is between 1 ?m and 100 ?m for allowing a substantial displacement of the optical fiber inside the lumen during the centering.

  • Patent number: 9052466
    Abstract: The present document describes a female optical receiving device for connecting a first optical fiber to a second optical fiber. The first optical fiber is substantially centered within a proximal portion of a guidewire tubing. The female optical receiving device comprises a first ferrule or tubing having a longitudinal axis and an inside diameter adapted to an outside diameter of the guidewire tubing, and a second ferrule or tubing having a longitudinal axis and an inside diameter adapted to an outside diameter of the second optical fiber. The longitudinal axis of the first ferrule or tubing is aligned with the longitudinal axis of the second ferrule or tubing.

  • Publication number: 20150041357
    Abstract: The pillbox comprises a pill receptacle comprising a number of pill compartments; and a cover sheet attached to the pill receptacle. The cover sheet has a sealing sheet with cells defining borders above each pill compartment. The cover sheet also has a protective sheet removably attached to the bottom surface of the sealing sheet. Protective tab tearing lines are provided on the protective sheet that allow portions of the protective sheet to be removed from the sealing sheet while other portions of the protective sheet remain attached to the sealing sheet in the form of protective tabs. Tearable tab tearing lines are provided on the sealing sheet that are disposed to form tearable tabs on the sealing sheet, the protective tabs corresponding to respective the tearable tabs. The tearable tab tearing lines define, for each the tearable tab, a tearable tab main portion and a tearable tab tongue portion linking the tearable tab main portion to one of the cell borders.

  • Patent number: 8936401
    Abstract: A method for terminating a first optical fiber within a proximal portion of a guidewire tubing. The guidewire tubing has an outside diameter defined as having a tolerance of ±0.001? or less. The method comprises the step of centering the first optical fiber within the guidewire tubing. A female optical receiving device used to receive an optical guidewire and connect guidewire internal optical fiber to an external relaying optical cable is also provided.

  • Patent number: 6842254
    Abstract: An apparatus and a method of measuring an optical path difference in a sensing interferometer. Light from a source is directed in the sensing interferometer. The light reflected from the sensing interferometer is splitted into first and second beams respectively directed into two reference interferometers having optical path differences greater than the coherence length of the source and such that the optical signals are in quadrature. The intensities of the light transmitted by the reference interferometers and recombined light reflected from the reference interferometers are detected for measuring the optical path difference in the sensing interferometer. Additional light sources allow for correction of internal perturbations and absolute measurement of the optical path difference in the sensing interferometer.
