摘要： An inrush circuit for electronic devices is particularly useful for Point-of-Sale printers. The circuit applies an active feedback-controlled voltage ramp to a bulk capacitor by means of a P-channel field effect transistor that is operated linearly after a controlled delay for contact bounce.

摘要： A method of controlling noise in an impact printer that modulates the input pulse to the power amplifier of the printer. The resulting current waveform is then applied to the print wire solenoids. The final shape of the force input to the platen reduces or spreads the spectral envelope containing problem harmonics and acoustic output noise.
