Low-cost, low-power, clockwork syringe pump
HardwareX, 2023 A low-cost ($120 NZD, $75 USD), low-power (1-year battery life), portable, and programmable syringe pump design is presented, which offers an alternative to high-cost commercial devices with limited battery life. Contrary to typical motor-driven syringe pumps, the design utilizes a compression spring coupled with a clockwork escapement mechanism to ...

Power Valve: for low power operation and low stand-by power
IEICE Electronics Express, 2005 The concept of Power Valve is presented. It consists of power switch transistors and control circuits, which give variable impedance to the power supply. The circuit controls the internal power supply voltage of logic circuits and reduces the voltage swing of signals. An experiment using a 130-nm test chip showed a 36.0% operating power reduction for a
