The main area for application of the sensor design would be in the food processing and packaging industry where position resolution of the end effector is in the millimeter to submillimeter range. The sensor concept consists of a grid of laser light detectors attached to the stationary base and a grid of lasers attached to the mobile end effector. The photo detectors on the base provide one level for position detection enhancement, i.e. the density of the sensor array. The second degree of freedom in improvement comes from the strategic positioning of a set of lasers attached to the end effector.

Reconditioning of mould and die tools involves the following manufacturing processes; identification of defects, cleaning of mould/die tool, deposition of material (metal), welding of material (TIG/laser), rough machining and finishing to specs, polishing and heat treatment, in sequential order. Current technology trends in the reconditioning of mould and dies is presented. The different defects that occur in mould and die tools that can be repaired such as wear, craters, chipping, etc are presented. Using the knowledge of the different manufacturing process and defects that occur in mould and die tools, specifications of a mechanical manipulator for reconditioning of mold and dies are determined. Finally, suitability of 5-axis milling machine technology for re-conditioning of mould and die tools is evaluated. This is done by presenting current 5-axis milling technology.

In semiconductors, a small forbidden gap is present between the valence band and the conduction band. Forbidden gap is the energy gap present between the valence band and conduction band in which no electron energy levels are allowed. Hence, electrons do not stay or exist in the forbidden gap.
