  • Movable electric device
    Patent number: 11937751
    Abstract: The present disclosure provides a movable electric device. The movable electric device includes a movable device body and a contact detection electrode. The movable device body has an electric drive means. The contact detection electrode is mounted on the movable device body. When the contact detection electrode _contacts diffusible dirt, a resistance, capacitance or impedance of the contact detection electrode varies.

  • Dual-stage optical isolator minimized polarization mode dispersion and simplified fabrication process
    Patent number: 7023618
    Abstract: An optical isolator includes a first stage configured to refract a light ray applied in a forward direction into a first ray and a second ray. A second stage rotated 90° with respect to the first is configured to refract said first and second rays in a substantially parallel manner. The isolator is configured such that the first ray comprises an e-ray with respect to the first stage and an o-ray with respect to the second stage, and the second ray comprises an o-ray with respect to the first stage and an e-ray with respect to the second stage, thereby substantially reducing the effects of polarization mode dispersion.
