An application for a flow control system includes a movable plunger held within a stationary riser, the stationary riser being in fluid communication with a drainage system. In the plurality of memory cells, data applied through a bit line depending on potentials applied to a top word line and a bottom word line are stored in a charge trap insulator or the data stored in the charge trap insulator are outputted to the bit line. A word line driving circuit activates one of word lines in response to the activation of a second timing signal. The actuator receives an electrical input and generates in response a corresponding force acting on the piston and causing a needle-free transfer of the substance between the reservoir and the biological body. The processing of the audio may comprise removing portions of the captured audio arriving at the microphone via one or more reflection paths. A ring having tabs is inserted within the recesses of the extension.
