A vehicle under floor storage compartment is proposed which includes a rotating tray provided in a concave storage portion formed underneath a floor panel, and a first lid which opens and closes this storage portion. The methods for forming an ultra porous sol-gel monolith include forming a solution comprising a porogen, a matrix dissolving catalyst and a sol gel precursor; allowing the solution to form a gel; and drying the gel at an elevated temperature. This technique avoids the need to store the second subset of the cache tag information in the main cache. The seal and mask having the seal in this embodiment is tailored to patient by causing the formable portion of the seal to be placed in a malleable state, applying the seal to the patient while the formable portion is in the malleable state, and causing the formable portion to be placed in a fixed state to retain a shape generally conforming to the portion of the patient underlying the seal.
