  • Energy converters and associated methods
    Patent number: 8358049
    Abstract: Energy converters and associated methods are disclosed herein. In one embodiment, an energy converter includes a first structural member spaced apart from a second structure member, a first piezoelectric element and a second piezoelectric element individually coupled to the first structural member and the second structural member, and a deflection member tensionally suspended between the first and second piezoelectric elements. The deflection member is substantially rigid.

  • Adjustment system for exercise machines
    Patent number: 5378216
    Abstract: An exercise device, as for example, the wing on a butterfly exercise machine, is arranged to be moved from an at rest position in an exercising direction in a range of travel counter to a load and to be returned to the at rest position by the load. An adjustment mechanism between the exercise device and load selectively adjusts the start of the travel range by movement of the exercise device in a direction opposite from the exercising direction. The adjustment mechanism includes a rack and pawl arranged to be engaged with one another when the exercise device is moved in the exercising direction.
