Abstract: A wind turbine control system and method, for the type of wind turbines includes a rotor, an asynchronous generator driven by the rotor and configured for providing an active power to a grid, and a power converter connected to the generator and configured to interact with the generator for generating the required active power for the grid. The control system includes a converter control unit for controlling the power converter and for estimating a frequency derivative of the frequency of the grid, and a wind turbine controller configured for receiving the estimated frequency derivative and for considering the received frequency derivative for determining a synthetic inertia. The converter control unit controls the power converter to cause the generator to also provide the synthetic inertia, in the form of active power.

Abstract: Rehab Ready Application assists users in their efforts to diagnose injury and suggest treatments through audiovisual recordings, photographs, written or oral instructions for treatment, and teleconferences or referrals to medical providers. Users indicate location of pain, mechanism of injury, level of pain, type of pain, degree of pain, range of movement and other symptoms. The application recommends specific exercises, repetitions, and duration for the treatment. Users can choose to view photos or recorded demonstrations of the treatment, written instructions, or a teleconference with a medical professional who can demonstrate the treatment and/or observe the user perform the treatment and offer feedback. Depending on the user's progress, additional treatment may be recommended or the user may be scheduled for an in-office visit with a medical professional if the injury is too severe for treatment via the application.
