A system is provided for advising in the selection of products to offer customers. In a representative embodiment, the MEMS device includes a deformable membrane supporting a plurality of light-reflecting segments that form the deformable mirror. By providing a web former comprising spaced bond areas suspended upon angled interconnecting membranes a hollow structure is achieved which is flexible and can be used in conjunction with a damping filler to achieve desired performance. A power and hydraulic system operates the various hydraulic components on the trailer. A pixel value around a boundary of the current block is smoothed based on the type of the current block and the smoothing value.
