A control system for controlling an operation of a hydroelectric turbine. Transmit circuitry can include a transmit coil operatively part of a transmit resonant circuit that exhibits resonance at a transmit resonant frequency and an unloaded Q value of at least about 20. Methods of making co-precipitates of a water insoluble food ingredient material and a hydrophilic polymer are provided. In another form, systems and methods are provided to bend in situ an elongate spinal implant associated with an orthopedic construct. By ultrasonic vibration of the punching tool, the thin-walled portion can be forced into a bone thereby preparing a recess of which is not rotationally symmetric. The system of the present invention is made up of processing arrangements executed by software which provides for the formation of spaces, and the creation of objects within those spaces, on a graphical user interface Playing Field display.
