  • Patent number: 10025058
    Abstract: A gap compensation mechanism capable of self adaptive posture adjustment is disclosed, which comprises a base seat, having at least a fixation portion disposed thereon, the fixation portion having a flow path area disposed peripheral thereto; at least an adjustment unit, sleeved onto an outer rim of the fixation portion; and a filler, being filled within the flow path area. As such, a workpiece to be fixed may be disposed on a face of an adjustment unit. Further, the adjustment unit provides at least three freedoms for the altitude and two axial inclinations for self adaptively compensating a gap with any geometrical shapes and thus further adjusting the posture of the combined workpiece. After all the adjustments, a filler is filled to reinforce the structure and finally a fixation unit is employed for locking and fixing.

  • Patent number: 8823927
    Abstract: The present invention discloses a system and method for nondestructively measuring the refractive index and the central thickness of a lens. The system comprises a radius measurement module arranged for measuring the curvature radius of the first surface of the lens; a focus measurement module arranged for measuring the best focus distance of the first surface of the lens; and a calculation module arranged for performing the first or the second calculation process according to the lensmaker's formula. Wherein, when the central thickness is given, the calculation module performs the first calculation process according to the curvature radius, the best focus distance and the central thickness to calculate the refractive index. On the contrary, when the refractive index is given, the calculation module performs the second calculation process according to the curvature radius, the best focus distance and the refractive index to calculate the central thickness.

  • Patent number: 6797959
    Abstract: The sensitivity adjusting equipment applied to a photoelectric smoke detector is provided. The photoelectric smoke detector includes a luminous component for providing an input light and a detecting component for receiving an even output light. The sensitivity adjusting equipment includes a light-scattering device having a scattering component and an adjustable hole for scattering the input light evenly and adjusting an intensity of the input light so as to output the even output light to the detecting component. The sensitivity adjusting equipment also includes a movable platform having a first brace connected to the photoelectric smoke detector and a supporting base having a second brace connected to the light-scattering device. The movable platform is moved to make the photoelectric smoke detector and the light-scattering device combined to adjust the sensitivity of the photoelectric smoke detector.
