Abstract: A non-volatile Boolean logic circuit based on memristors and an operation method, which performs logic operations on the input logic value P and/or the input logic value Q. The logic circuit includes: a controller, a memristor M1, a memristor M2 and a resistor. The controller sets the memristor M2 to a high resistance state before performing the logic operation. When performing the logic operation, a voltage A is applied to the memristor M1, a voltage B is applied to the memristor M2, a voltage C is applied to the resistor. The resistance state of the memristor M2 is the result of the logic operation. When a logic operation is performed on the logic value P and the logic value Q or only on the logic value Q, the controller further sets the memristor M1 to the resistance state corresponding to the logic value Q before performing the logic operation.

Abstract: An EMI filter network may be used to provide interference filtering for multiple loads (referred to collectively as a dynamic load). In one aspect, the EMI filter network includes electrical switches that establish different configurations or arrangements of passive circuit elements (e.g., inductors and capacitors) where each configuration generates a different filter value. The EMI filter network may be communicatively coupled to a controller which changes the configuration of the EMI filter network using the switches in response to the dynamic load changing operational states. For example, each configuration of the EMI filter network may correspond to one of the operational states of the dynamic load. Thus, as the operational state of the dynamic load changes—e.g., different motors become operational—the controller alters the configuration of the EMI filter network to provide a filter value that corresponds to the current operational state of the dynamic load.
