A robot mounting apparatus for a hip joint operation robot capable of firmly attaching a hip joint operation robot to a femur in order for operation robot to perform an accurate femoral canal cavity operation, and a hip joint operation robot system using the same. The robot mounting apparatus for a hip joint operation robot, comprising: a fixing means for fixing to a femur, including: a bar having a predetermined length and being arranged in perpendicular to a femur; and a seizing means having a predetermined shape for seizing the femur, the seizing means forms at an end of the bar; an installation unit having a predetermined shaped for installing the operation robot thereon, the installation unit is positioned near an end portion of the femur; and a link having a predetermined length for connecting the installation unit and the bar of the fixing means, the link is installed in parallel with respect to a longitudinal direction of the femur. The hip joint operation robot system employs the robot mounting apparatus and the robot firmly mounted on the robot mounting apparatus.

A transmission-type extrinsic Fabry-Perot interferometric optical fiber sensor and a method used for integrity monitoring of structures and measuring strain and temperature are provided. The transmission-type extrinsic Fabry-Perot interferometric optical fiber sensor includes first single-mode optical fiber and second single-mode optical fiber, laser device, and optical detector. The first single-mode optical fiber is inserted into an end of a capillary quartz-glass tube and the second single-mode optical fiber is inserted into the other end of the capillary quartz-glass tube. Air gap is formed between the first single-mode optical fiber and the second single-mode optical fiber in the capillary quartz-glass tube. Gap length of the air gap changes in response to magnitude and direction of transformation of the capillary quartz-glass tube. The laser device launches light into an end of the first single-mode optical fiber. The end of the first single-mode optical fiber is not inserted into the capillary quartz-glass tube. The optical detector detects interferometric fringe of light. The light is launched from the laser device and passed through the first single-mode optical fiber, the air gap, and the second single-mode optical fiber. The number of occurrence of the interferometric fringe and trend of signal level are determined by change of the gap length.

Disclosed herewith is a prosthetic foot. The prosthetic foot is to be connected to a pylon that is utilized for the substitution of the shinbone of an amputee. The prosthetic foot includes an ankle portion to be secured to the pylon. A plurality of curved portions are extended from one end of the ankle portion. A sole portion is extended from one end of the curved portions. The ankle portion, the curved portions and the sole portion form a single integrated plate spring structure.
