An improved system and method for detecting leaks in substantially enclosed objects such as automobiles, airplanes, tanks, etc. In one embodiment, an imaging device capturing a digital image broadcasts an invitation to wireless devices in the surrounding area. The logic circuit maintains power to the write receivers whenever the high-power, low write latency mode has been enabled if a row of memory cells in the memory device is active, the memory device is not being operated in the power down mode, and the read transmitters in the memory device are not active. For opening and closing the second line, the valve closure body is movable in the valve housing in the axial direction of the bore thereof. In one application, the plasma generation system is useful to manipulate the flow of jets and provide highly efficient acoustic noise reduction. This invention also includes truffle mycelium cultivated according to the process of the invention, aromatized products having the smell and the taste of natural truffle fruiting bodies and extracted from said truffle mycelium, as well as aromatized substrates containing the same aromatized products.
