  • Publication number: 20210136892
    Abstract: A light emitting diode (LED) lamp includes at least one LED and an LED driver. The LED driver includes at least two terminals, a burning processor, and an address memory. The at least two terminals have a power input terminal and a power output terminal. The power input terminal and the power output terminal are externally coupled to a power line. The burning processor receives a burning activation data of a burning signal through the power input terminal or the power output terminal, and directly and externally receives a burning address data of the burning signal without from the power line. When a burning function of the burning processor is activated by the burning activation data, the burning processor converts the burning address data into a local address data and burns the local address data into the address memory.

  • Publication number: 20210135265
    Abstract: A major challenge in the development of anion exchange membranes for fuel cells is the design and synthesis of highly stable (chemically and mechanically) and conducting membranes. Membranes that can endure highly alkaline environments while rapidly transporting hydroxides are desired. A design for using cross-linked polymer membranes is disclosed to produce ionic highways along charge delocalized pyrazolium and homoconjugated triptycenes. The ionic highway membranes show improved performance in key parameters. Specifically, a conductivity of 111.6 mS cm?1 at 80° C. was obtained with a low 7.9% water uptake and 0.91 mmol g?1 ion exchange capacity. In contrast to existing materials, these systems have higher conductivities at reduced hydration and ionic exchange capacities, emphasizing the role of the highway. The membranes retain more than 75% of initial conductivity after 30 days of alkaline stability test.
