A projection system is provided that utilizes a prism which guides color components from a light source to a display without the use of reflection, and that reflects image encoded light from the display toward a projection lens, thereby minimizing loss of luminance and improving contrast. The system includes a first hypertext transfer protocol server, a database server in which the multimedia content is stored in a structured arrangement, and an application server that is in communication with the hypertext transfer protocol server and the database server. In a variant, method for making an implant or component thereof includes forming a standard shape foamed blank, and over-molding a thin layer of non-foamed PEEK material onto the standard shaped foamed blank to obtain a final implant component geometry, whereby the blank is completely encapsulated by the over-molded layer. A drive electrode is located on the substrate surface adjacent the distal portion of the tube. The current environmental condition associated with the calculated resistance value is determined by consulting the manufacturer’s specification sheet for the sensor. The Fresnel lens may be made from polycarbonate while the overmold may be made from a poly or a thermoplastic polyurethane.
