  • Orthosis knee joint and sensor
    Patent number: 7410471
    Abstract: A selectively lockable orthotic joint is provided in which a pressure sensor having a thin layer of variably resistive material generates a control signal when an actuation force is applied to the sensor. An electronic circuit operatively connects the sensor to a mechanical orthotic joint that can be selectively locked and unlocked in response to the control signal. The control signal may be uniform in strength selectively locking and unlocking the joint. The control signal may also be variable in strength wherein the orthotic joint provides increasing or decreasing resistance to motion responsive to a corresponding increase or decrease in control signal strength. The device is suitable for use as a foot/ankle/leg orthotic having a foot sensor which selectively operates a mechanical knee joint.

  • Orthosis knee joint
    Patent number: 6770045
    Abstract: A selectively lockable orthotic joint is provided that in one embodiment includes at least one pressure sensor and an electronic circuit associated with the pressure sensor for generating or providing a control signal indicative of pressure, force or other value sensed by the sensor. A mechanical orthotic joint is provided that has a locking mechanism that can be selectively locked and unlocked in response to the control signal.
