Abstract: This abstract describes a simple, low-cost device to improve power yields provided by fixed solar panel installations without the need to precisely position optical elements above the panel or add solar tracking and array positioning systems. The device utilizes one or more layers of optically refractive and/or diffractive materials imbued with specific contours and/or optical characteristics. The device is bonded directly to the solar array's sun-facing surface either as the array is manufactured, or retro-fitted to the array after installation. The device and bond interfaces may be comprised of any suitable optically high-transmittance material with refractive indices sufficiently higher than that of air. Additional gains in solar array power yields are made possible by the use of transparent, variable-contoured overlays or fluid-filled polymeric film overlays with modifiable optical characteristics which adapt to sun angle.

Abstract: A method and apparatus have been developed to precisely position and distribute an adhesive sealant for the purpose of blocking corrosion paths to electrically conducting surfaces on battery terminals. In order to achieve this objective, the present invention makes use of a rectangular-shaped, sealant-packed laminate with a battery post cut-out that is wrapped around and bonded to the terminal by the user at the work site or, alternatively, by the terminal fabricator for first-time use. In either case, corrosion path gateways are blocked on both top and bottom sides of the terminal's post-hole aperture by the act of seating a thusly wrapped terminal on the battery post and depressing the terminal against the battery plane before tightening the securing bolt. Seating the seal-wrapped terminal thusly positions sealant around the battery post base, effectively denying corrosive elements an entrance to electrically-conducting surfaces.
