ABSTRACT

One variation of a method includes: receiving a recycled wood workpiece in an
inductor volume; accessing an image of the inductor volume; based on a set of
features detected in the image, detecting a first reflective elliptical object
embedded in a surface of the recycled wood workpiece and deriving a first
location of the first reflective elliptical object. This variation of the
method further includes: identifying the first reflective elliptical object as
a first metal fastener occupying the first location; triggering the stage to
drive an inductor, arranged within the inductor volume, within a target
coupling distance of the first location of the first metal fastener; and
triggering a driver to supply a target alternating current to the inductor to
heat the first metal fastener via induction heating and to reduce retention of
the first metal fastener by the recycled wood workpiece.
