The assembly described herein is secured to lawn equipment for adding additional functionality, such as weed eating. The assembly includes a base having at least one base bracket for selectively coupling the assembly to the lawn equipment. Further, a stem is included having a stem bracket coupled to the base, a stem housing extending from the stem bracket, and a shoulder in rotational engagement with the stem housing. For maneuvering the assembly, an arm is pivotally engaged with the shoulder of the stem and pivotally coupled to the arm actuator. The arm may be radially, angularly and translatably repositioned during use.

Lawnmower attachment assembly

A method of performing active shielding of an electronic device from a magnetic field having a first flux, using a circuit; having the steps of: measuring, using a Hall effect sensor, a first magnitude and a first direction of the first flux; creating an output voltage equal to the first magnitude; feeding the output voltage to a differential amplifier; amplifying the output voltage to create an amplified output; comparing, using an error amplifier, the amplified output to a reference voltage to determine an error voltage; feeding the error voltage to an electric power switching circuit; generating a switching waveform based on the error voltage; feeding the switching waveform as an input to a driver module; creating, based on the input, a current having amplitude equaling the first magnitude and a second direction opposite of the first direction, such that a second flux is created to cancel the first flux.
