An optical noninvasive vital sign monitor comprising a reflectance-type optical sensor within a pressurizable capsule retained by a headband, the capsule having an optically transparent or translucent inner wall adapted for placement against a subject’s forehead. A first fold line is located at the transition from the back part to the closing flap. At least the post-annealing is performed in a pressurized atmosphere including at least one of oxygen and ozone. The technology described in this specification also provides a tapered platform device that provides a self-aligning weapon indexing cradle allowing the shield user to accurately return the weapon’s aimed impact point back on target following inherent up and down and side to side shaking movements of a recoiling weapon during the firing process. The invention also contemplates numerous diagnostic platforms that together with the novel antibodies can support economical, fast, and highly selective detection and identification of clinical inoculum samples.
