  • COMPOSITIONS FOR ACTIVE TREATING AND PREVENTING PLANT DISEASES
    Publication number: 20190274302
    Abstract: Compositions contain anti-microbial agents that can kill, inhibit, and/or prevent the growth of the microbes. The composition contains carrier and/or retainer forms a protective barrier on the surface of the plants when the composition is applied onto the plants. The carrier forms one or more layers of bio-barrier, which serves as a protective layer preventing microbes and/or other harmful microorganisms or virus from contacting and infecting the plants. The retainer serves as a chemical glue (e.g., a water soluble glue) for increasing the contact time and contact numbers between the anti-microbial agents and the harmful microbes. The compositions are all made from ingredients that are from food-grade, organic, or GRAS (Generally Recognized as Safe) materials under 21 C.F.R. 174-178 (C.F.R.: U.S. Code of Federal Regulations).

  • STATIC RANDOM ACCESS MEMORY (SRAM) ARRAY POWER SUPPLY CIRCUIT
    Publication number: 20190035435
    Abstract: A Static Random Access Memory (SRAM) array power supply circuit is presented. The circuit comprises an SRAM test unit having a substantially same structure as a basic SRAM unit in the SRAM array; a switch device connected to a power source, the SRAM test unit, and the SRAM array; and a switch control circuit connected to the SRAM test unit and the switch device. When a test voltage in the SRAM test unit is lower than a threshold voltage, the switch device is closed so that the power source begins to charge the SRAM array and the SRAM test unit. The SRAM test unit provides an early warning for the SRAM array, allowing the latter to be charged upon fulfillment of a condition (e.g., charge is low). Compared to conventional circuits, this circuit provides an output voltage that is more stable and less susceptible to the changes in external conditions such as temperature or pressure.
