In its simplest form, the invention is an array of 10 triangles arranged in a specific pattern. Inside the lighter shell, the piezoelectric unit is located between the trigger and the safety button. The update means intermittently constrain these filter coefficients by eliminating circular wrap-around artifacts of the circular convolution. Disruption of YbeY activity can lead to increased sensitivity to antibiotics. The device is effective for people in need of a constant air source.
