A quick heater for drinking water includes a helical water pipe defining a narrow space therebetween for fitting an electric heating tube and having a water inlet and a water outlet. The birdcage, having a grid floor retains and separates the bird from the system, while allowing the waste and airborne contaminants from the caged bird to gravitate to the system’s constant medium being a hydraulic body of water contained in a tray beneath the birdcage. Using an aspirator allows a more efficient and cost-effective operation of the VMD system and method, particularly in a desalination application. Other implementations may include a first stage that also performs continuity preservation between last blocks of audio signal and the first blocks of audio after it is detected that relevant audio signals are resumed. In further embodiments, a receiver is able to calculate a transmission window to occur during a lower priority technology network interval, and transmit a silencing frame during the calculated transmission window. The button platform 46 could also be selectively movable along a limited distance of the anterior periphery of the body to allow a user 12 to adjust the present invention 10 to conform to different sized hands and fingers of varying lengths.
