Abstract: Systems and methods that use an optical impedance sensor that eliminates electricity for measuring fuel quantity in fuel tanks. The optical impedance sensor comprises two optical fibers spaced apart inside a meniscus tube, one to transmit light along its length and the other to receive light along its length. The meniscus tube minimizes the sloshing of fuel level. The fuel level in the tank modulates the optical impedance between the two optical fibers, resulting in changes in the total light received by an optical detector. Depending on fuel tank height, the optical impedance sensor may comprise different embodiments in which the detection apparatus shapes the light to be unidirectional (emitted and collected only on one side of the fiber) or omnidirectional (all directions).

Abstract: A fungicidal composition having a synergistic effect is provided. The composition comprises active ingredients A and B. The active ingredient A is polyhexamethylene biguanide or an agriculturally acceptable salt thereof, the active ingredient B is one selected from prochloraz, epoxiconazole, benthiavalicarb-isopropyl, zoxamide, azoxystrobin, prothioconazole, difenoconazole, fenamidone, polyoxin, iprodione, acibenzolar, dithianon, pyraclostrobin, trifloxystrobin, picoxystrobin, fluazinam, thifluzamide or dimethomorph, and the weight ratio of the two ingredients is from 1:50 to 50:1. The test results show that the fungicidal composition according to the present invention has an obvious synergistic effect, and importantly, the application rate is reduced, such that the cost is lowered. The application rate of a single agent alone is effectively reduced by combining the fungicides of different mechanisms and modes of action, which is beneficial for broadening the fungicidal spectrum, retarding the resistance development of the fungi and improving the control effect.
