Abstract: An optical fiber transducer usable in environments of extreme operating temperature features a stationary support, a movable body displaceable back and forth relative thereto, and an optical fiber connected between the support and the movable body. The fiber has a Fiber Bragg Grating in an intermediate region thereof between the support and movable body. To accommodate varying coefficients of thermal expansion (CTEs) among these components, one or more tubes close circumferentially around the fiber. Each tube has a CTE that is greater than that of the fiber, and less than that of the constituent material of the support and movable body. The fiber is bonded to an interior of the tube(s), while an exterior of the tube(s) is bonded to the support and movable body.

Abstract: The optical sensor generally has a frame having a deformable member mounted to the frame, and a sensing optical fiber being fixedly attached to a portion of the deformable member, the sensing optical fiber having at least one ?-phase-shifted fiber Bragg grating inscribed thereon, the at least one ?-phase-shifted fiber Bragg grating of the sensing optical fiber deforming together with the deformable member when the frame is subjected to a force.

Abstract: A bottle holder system mountable to a bicycle (10), wherein said bicycle comprises a down tube (18) and a seat tube (20), wherein said bottle holder system comprises: a first bottle holder (100) comprising (i) a first bottom wall (104) mountable to a rear side of the down tube, (ii) a first left side wall (106), and (iii) a first right side wall (108) all forming a first interior cavity (110) shaped for receiving a first round bottle (112); a second bottle holder (200) comprising (i) a second bottom wall (204) mountable to a front side of the seat tube, (ii) a second left side wall (206), and (iii) a second right side wall (208) all forming a second interior cavity (210) shaped for receiving a second round bottle (212); wherein the down tube, the seat tube and exterior surfaces of said first left side wall, second left side wall, first right side wall and second right side wall cooperate to form an airfoil shape (500).
