POLICY-ENABLED ENCRYPTION KEYS HAVING COMPLEX LOGICAL OPERATIONS

摘要

An active noise cancelling power supply to perform active noise cancelling of input power with noise to output power. The active noise cancelling power supply having a power transformation device receiving input power and converting the power to a voltage signal with a ripple. The active noise cancelling power supply has a ripple measuring device, which measures the ripple as the voltage signal with a ripple passes through the ripple measuring device producing a ripple signal. A controller with a data storage in communication with a processor, wherein computer instructions in the data storage are configured to instruct the processor to produce a first noise cancellation signal in volts or millivolts out of phase with the ripple signal and inject the first noise cancellation signal on the voltage signal with a ripple at a node forming a clean signal as output power.
