  • Patent number: 10172200
    Abstract: A system for regulating the minimum output current of an LED dimming power supply, comprising: an initial value setting module, a data detection module, a data processing module, an output adjustment module, a DC/DC current output module electrically connected with the output adjustment module, a regulated load connected in series at the output of the DC/DC current output module, and an output regulation module. The present invention is capable of utilizing those modules mentioned above to make the regulated load modularization and standardization. It means that the resistance of the regulated load is designed to a standard value, and the regulated load is set in a standard module, when the batches of LED dimming power supply need to regulate the minimum output current.

  • Patent number: 9266261
    Abstract: Flexible nanocrystalline cellulose films (NCC) include a polymer while retaining the property of tunable color. Polymers, for example PVOH and SB-latex, are effective in increasing the flexibility of the NCC films. The NCC film made with PVOH retains the iridescence better than that made with SB-latex; however, the NCC film made with SB-latex has a better tensile strength. In addition, the NCC film made with PVOH was found to disperse easily in water while the NCC film made with SB latex does not disperse in water (it is strongly water resistant). The color of NCC film made with PVOH and SB-latex can still be tuned with techniques that provide for tuning.

  • Patent number: 5433827
    Abstract: Acidic papers, books, and other sheets of cellulosic material may be deacidified and so given a prolonged life by bringing the papers, books, or other sheets of cellulosic material to be treated in intimate contact with a source of solid alkali such as calcium carbonate filled paper, at an elevated humidity and under mechanical pressure for a period long enough to produce deacidification; the process differs from other processes in that it is carried out in the solid state without the use of liquid or gaseous reactants.
