  • Publication number: 20120190502
    Abstract: The invention comprises a method and/or an apparatus using computer configured exercise equipment and an electric motor. A computer-controlled robotic resistance system is used for training, diagnosis and/or therapy. The resistance system comprises: a subject interface, software control, a controller, an electric servo assist/resist motor, an actuator, and/or a subject sensor. The system overcomes the limitations of the existing robotic rehabilitation, weight training, and cardiovascular training systems by providing a training and/or rehabilitation system that adapts a resistance or force applied to a user interactive element in response to the user's interaction with the training system, a physiological strength curve, and/or sensor feedback. For example, the system optionally provides for an automatic reconfiguration and/or adaptive load adjustment based upon real time measurement of a user's interaction with the system or sensor based observation by the exercise system as it is operated by the subject.

  • Patent number: 7579578
    Abstract: The present invention provides a pseudospark switch that overcomes the aforementioned limitations of existing pseudospark switches and proved e-beams for applications such as FELs, pulsed lasers, X-ray machines, and radar. The improvement in e-beam quality is obtained by inductively ionizing gas inside the hollow cathode chamber (HCC), prior to main gap breakdown using a HCC that incorporates a spiral induction coil. The gas in the hollow cathode chamber is ionized by the discharge of an auxiliary capacitor bank through the spiral coil that forms the back surface of the HCC.
