Abstract: A load control device is adapted to be disposed in series with an AC voltage source and an electrical load and is operable to provide substantially all voltage provided by the AC voltage source to the load. The load control device comprises a controllably conductive device, a controller, a zero-crossing detector, and a power supply for generating a substantially DC voltage for powering the controller. The power supply is operable to charge an energy storage device to a predetermined amount of energy each half-cycle. The controller is operable to determine when the power supply has stopped charging from the zero-crossing detector each half-cycle, and to immediately render the controllably conductive device conductive to conduct the full load current. Before the controllably conductive device begins to conduct each half-cycle, only a minimal voltage develops across the power supply to allow the energy storage device to charge.

Abstract: Methods and apparatus for back exercise are provided. An exercise bench apparatus includes a beam positioned at an incline with respect to the horizontal, a seat member coupled to the beam wherein the seat member is configured to be positioned at a selectable position along the beam, a knee brace coupled to the beam, the knee brace configured to be positioned at a selectable position along the beam, and a stabilizer arm rotatable with respect to the beam and configured to be rotated away from a user in a first position, the stabilizer arm configured to engage the user in a second position such that a pelvic region of the user is substantially immobilized.
