Abstract: A system for degaussing a magnetized structure can include a given circuit that provides a differential alternating current (AC) signal that decays from an upper level to a lower level over a predetermined amount of time. The system also includes a given electrical coil coupled to the given circuit. The electrical coil circumscribes the magnetized structure. The electrical coil induces a decaying magnetic field on the magnetized structure in response to the differential AC signal to convert the magnetized structure into a degaussed structure.

Abstract: A low voltage dimmer for LED lamps incorporates an AC-DC power supply along with a Pulse Width Modulator (PWM) to modify the power delivered to an LED load is configured to fit inside the form factor of a standard single gang electrical to control the intensity of the light emitted by the LED. The PWM portion of the dimmer circuit incorporates a microprocessor configured to produce a train of output pulses and controlled by a variable input voltage to modulate the output duty cycle of these pulses to drive one or more LED lamps to switch between “on” and “off” conditions. Variation of the duty cycle of the pulses regulates the total amount of time in each cycle that the lamp is illuminated, with the aggregate “on” time determining the apparent brightness of the lamp.
