  • Publication number: 20170266156
    Abstract: The present invention relates to a method for preventing cancer by using a phthalide compound, wherein the phthalide compound has an effect of increasing the oxygen release efficiency of hemoglobin (Hb) of a subject to increase the oxygenation level of organs and tissue cells, thereby preventing the cellular oxygenation level against falling below the critical cellular oxygen requirements under which the normal cells can turn cancerous. Although cancer may be caused by a variety of reasons, including congenital inheritance, external environment, air pollution or poor living and dietary habits, there is only one primary and common reason in causing cancers, the excessively low cellular oxygenation level. When the oxygenation level of any cell falls below 60% of its physiological oxygen requirements, the normal cell may turn cancerous.

    Abstract: The present subject matter is directed to a system and method for operating an electrical power circuit connected to a power grid. The power circuit includes a power converter electrically coupled to a generator. The method includes monitoring at least one speed condition of the generator during operation of the power circuit. Another step includes determining one or more voltage conditions of the power circuit. The method also includes calculating a maximum reactive current for the generator as a function of at least one of the speed condition or the one or more voltage conditions. Thus, the method also includes operating the generator based on the maximum reactive current so as to prevent an actual modulation index of the power converter from exceeding a predetermined threshold.

  • Patent number: 9748653
    Abstract: Differing from conventionally-used miniature cubic antenna being provided with a signal transceiving conductor on the outer surface thereof, the present invention provides a multilayer chip antenna formed by sequentially stacking a first coupling substrate, a signal transceiving metal layer, and a second coupling substrate. Particularly, the first coupling substrate and the second coupling substrate are disposed with a first metal layer and a second metal layer, respectively. Therefore, when the signal transceiving metal layer transmits or receives a wireless signal, not only a first coupling capacitor is induced between the signal transceiving metal layer and the first metal layer, but also a second coupling capacitor is simultaneously induced between the signal transceiving metal layer and the third metal layer; meanwhile, the first and second coupling capacitors are helpful to enhance the impedance bandwidth as the multilayer chip antenna transmits and/or receives a high-frequency wireless signal.
