An apparatus is provided for loading water bottles into a water cooler. In addition, the process of the invention provides a method for mounting discrete electrical components at a significant distance removed from the underlying silicon surface. The estimated scatter provides for correction of scatter in a image. Further, the system presents a method of attracting and carrying pills using negative vacuum pressure, gravity and centrifugal force. The potential compensation device includes a charge compensation element having a free end that projects in an exposed manner into the air stream. The invention also includes a substrate having a plurality of holes defined therethrough, a layer of thermally formable material disposed onto the substrate covering the plurality of holes, and a plurality of microspheres thermally formed in the layer by means of applied pressure through the holes when it has been heated to a predetermined degree of plasticity.
