A method for making a magnetic component is provided. The processes generally include providing a propylene based polymer formed from a metallocene catalyst and melt processing the propylene based polymer to form a polymer article. A floss cartridge is coupled about the receiving mechanism and configured to dispense floss. Control software is configured to control a motion of the robotically guided instrument wherein the virtual remote center of motion constrains the motion of a robot. An escort ring is disposed over the etch stop layer and under the MEMS device, wherein the escort ring encircles the contact plug. Variations include electronically producing a virtual vibration and the use of multiple shear wave sources.
