  • Publication number: 20200113803
    Abstract: The present invention provides a novel anhydrous composition of small-molecule polysaccharides, consisting of at least a small-molecule polysaccharide and an anhydrous base. The formulation of the anhydrous composition of small-molecule polysaccharides allows the small-molecule polysaccharide to maintain a molecular size of 12-22 nm and the direct penetration of the small-molecule polysaccharide across the horny layer of skin. The present invention also provides a method of effectively maintaining skin hydration level in a subject in need thereof, comprising topically administering to the subject an anhydrous composition of small-molecule polysaccharides.
    Type: Application

  • Patent number: 8587207
    Abstract: An electronic ballast for a light emitting load is provided, and includes a transformer module, a resonance module, a high-frequency push-pull inverter and a driving controller module. The high-frequency push-pull inverter includes a first switch component and a second switch component. The driving controller module is used for generating and providing an asymmetric driving waveform to the first switch component and the second switch component. The asymmetric driving waveform includes a first discharging waveform portion for discharging and turning off the first switch component, and also a second discharging waveform portion for discharging and turning off the second switch component. The first and second discharging waveform portions are different in current amplitudes and time spans.
