  • Patent number: 7267673
    Abstract: The acne treatment devices use an array of LEDs, which emit monochromatic light substantially at a wavelength of 405 nanometers, which is coincident with the peak absorbance of light by acne porphyrins. The emitted light is directed from the light source to an acne area of the skin. The device can either be hand-held, with the LEDs mounted on a handle portion, or an LED can be mounted on a patch-like mounting element, which is adapted to be secured to the skin for longer exposure at less intensity.

  • Patent number: 7157816
    Abstract: The motor assembly which produces an oscillating action for a personal care device includes a horizontally positioned U-shaped stator portion, and an armature portion which includes a torsion spring shaft which is anchored at one end thereof. The armature portion also includes a U-shaped magnet mounting member which is fixed near the upper end of the spring shaft, the U-shaped member including two opposing legs which extend along a substantial part of the length of the spring shaft, away therefrom. At the tips of each leg are magnet assemblies, which interact with the stator portion in alternating torsion, to produce a back-and-forth oscillation of the armature and a brushhead or other workpiece attached thereto.
