  • Patent number: 7330364
    Abstract: A method and circuit for converting high voltage AC to low voltage DC using a switched power supply and rising edge conduction has an alternating current (AC) power source. A rectifier is coupled to the AC power source. A switching device is coupled to the rectifier. The switching device is opened and closed only during rising edge conduction. Control circuitry is coupled to the switching device for opening and closing of the switching device only during rising edge conduction. A storage capacitive element is coupled to the switching device.

  • Publication number: 20070173818
    Abstract: The present invention provides various interspinous vertebral implants and methods for using the same for dynamic stabilization of spine. The interspinous vertebral implants of the present invention comprises a resiliently compressible body that is adapted for position between adjacent superior and inferior spinous processes, and an anchoring member that is affixed to the superior and the inferior spinous processes posterior to the resiliently compressible body. The anchoring member provides a compressive force while the resiliently compressible body provides a distraction. Without being bound by any theory, it is believed that the combination of the distraction and compressive forces created by interspinous vertebral implants of the present invention results in a rotational moment, which alleviates compression on the intervertebral disk.

  • Patent number: 6555967
    Abstract: A low noise method and apparatus for driving electroluminescent (EL) panels provides reduction in EL panel noise, and in the preferred embodiment, voltage compensation as the EL panel ages. The output of a high voltage power supply is applied to the EL panel through a circuit having an optimized time-constant, producing a waveform that reduces EL panel vibration. Additionally, if the time constant is derived in part from the capacitance of the EL panel, the time constant may be chosen such that aging of the EL panel maintains the time constant in the proper range to maintain noise reduction over the life of the panel and compensate for brightness reduction due to aging of the EL panel.
