  • Patent number: 7881771
    Abstract: A bone reposition device includes first and second bone supports for supporting first and second portions of a fracture or osteotomize bone about a fracture or osteotomize site, a plurality of sequentially connected connection members and a plurality of joints each with at least a pair of adjacent parts for connecting the connection members therebetween and to the first and second bone supports. The plurality of joints includes at least six joints, each of which possesses one degree of freedom and allows controllable relative rotation or translation of said pair of adjacent parts about one of three axes respectively.

  • Patent number: 7162305
    Abstract: An electrical stimulation device for a body part of a person comprises an orthotic with sensor and electrodes and a controller. The controller receives a sensor signal, compares the sensor signal to a threshold value and generates an electrical output from the electrodes if the sensor signal exceeds the threshold value. A docking station facilitates connection of the electrodes and sensors to a computer. The docking station including a first processor for measuring values of the sensor signal and the electrical outputs and a second processor for generating electrical outputs on the electrodes.
