  • Publication number: 20160107316
    Abstract: A visuo-haptic sensor is presented which uses a deformable, passive material that is mounted in view of a camera. When objects interact with the sensor the deformable material is compressed, causing a change in the shape thereof. The change is shape is detected and evaluated by and image processor that is operatively connected to the camera. The camera may also observe the vicinity of the manipulator to measure ego-motion and motion of close-by objects. The visuo-haptic sensor may be attached to a mobile platform, a robotic manipulator or to any other machine which needs to acquire haptic information about the environment.

  • Patent number: 8908512
    Abstract: A method is provided for performing a rate shaping of multiple data streams which are to be transmitted through a network. The network has the capability to perform a rate shaping using a first rate shaping scheme and at least one other rate shaping scheme other than said first rate shaping scheme. The method can include determining based on the resources of the network the maximum number n of data streams for which said first rate shaping scheme can be applied as a rate shaping scheme, selecting n data streams among the multiple data streams which are to be transmitted and performing a transcoding on them to perform a rate shaping, and performing a rate shaping for other data streams using a different rate shaping scheme other than said first rate shaping scheme.
