  • Patent number: 9945667
    Abstract: The present invention relates to a sensing system and a sensing method using the same. The sensing system includes at least one tested unit and an optical fiber measuring unit. The tested unit includes a container, a strain arm and a float. The container can be filled with a fluid, and the strain arm is connected with the float and combined with a measuring portion of the optical fiber measuring unit. When the container is disposed on a body of interest, the surface inclination or settlement of the body of interest would cause changes of buoyant force on the floating element and induce bending deformation of the strain arm. Accordingly, the surface deformation of the body of interest can be determined by detecting the bending deformation of the strain arm using the measuring portion combined with the strain arm.

  • Patent number: 9868213
    Abstract: Technologies are generally described for detection of incidental robot-human contact. In some examples, a robotic actuator movement may generate a feedback signal, such as a haptic signal, a proprioreceptive signal, an optical signal, and/or an infrared signal. A tremor detector may determine whether the feedback signal contains a tremor signal characteristic of a human, for example by determining whether frequency components in the feedback signal fall within particular frequency ranges. Upon determining that the feedback signal does contain a tremor signal characteristic of a human, the tremor detector may conclude that the robotic actuator has come into contact with a human, and may cause the actuator to halt its movement.
