Abstract: A system for preloading piezoelectric actuators includes a fixture, a preloading mechanism configured to apply a mechanical force to a piezoelectric element supported by the fixture, and a sensor configured to sense an electrical property induced by the mechanical force in an electrical circuit having the piezoelectric element therein. A control device is coupled with the sensor and configured to generate a signal based on the sensed electrical property. A method of setting or testing preload includes applying a mechanical force to a piezoelectric element, and correlating an electrical property induced by the mechanical force with a magnitude of the mechanical force. Closed loop control allows preload to be set highly accurately.

Abstract: This invention relates to the combination of an outdoor swimming pool and adjustable roof structure mounted so as to extend over the pool and a patio adjacent to the pool. When the roof structure is in a raised position, the pool may be used by bathers, positionally adjustable curtaining extending between the roof structure and a ground area surrounding the pool and patio providing protection against adverse weather conditions. When the roof structure is in a lowered position, it prevents access to the pool, providing a safeguard against small children falling into the pool when it is not being used by adults. Additionally, when the roof structure is in its lowered position, insulating members carried thereby lie directly over the pool, minimizing heat loss therefrom. Desirably, the roof structure or part thereof may be moved to open the pool to the sunshine, while providing shade and protection against wind to non-bathers sojourning on the adjacent patio.
