A bridging device for supporting occlusive masses within an aneurysm located at a vascular bifurcation. The mounting hardware may be in the form of two-point mounting hardware that connects the seat back to the wheelchair and permits the seat back height to be adjusted independently of the mounting hardware location on the wheelchair. The computing device can then identify any user interface elements with which the user is attempting to interact. A sanding surface is provided on the tool handle for smoothing a workpiece. Analysis of this infrared signature classifies the relative flow rate, size and position of the feature fabricated in the part.
