摘要： An apparatus and method for tracking maximum power are disclosed. The apparatus is configured to track a maximum power at a certain node of an electronic circuit, adjust an impedance of the electronic circuit such that power at the node is maximal, and adjust an impedance of the electronic circuit by comparing power at two points in time to increase power. The apparatus for tracking a maximum power, includes a charge sharing capacitor connected to an initial capacitor in parallel, a first switch disposed between the initial capacitor and an energy harvesting power supply, a second switch disposed between the initial capacitor and the charge sharing capacitor, a third switch disposed between the energy harvesting power supply and a comparator, and a switched-capacitor power converting circuit configured to control the initial capacitor.

摘要： The present invention relates to a melanogenesis detection method using FAM86A, and the like. The level of FAM86A of the present invention decreases according to an increase in the amount of melanin secretion or formation, and thus the present invention can whiten the skin by using protein FAM86A or an agonist thereof, and can prevent, treat or alleviate melanin-deficiency diseases such as vitiligo since the formation and secretion of melanin is promoted when FAM86A is inhibited. Therefore, the present invention is expected to be used in various ways, such as a composition for skin whitening using protein FAM86A or an agonist thereof, and as a composition for preventing and treating melanin deficiency diseases including vitiligo and canities by using a FAM86A inhibitor.
