The primary objective of the present invention is to provide a set of simple methods and apparatus to obtain simultaneously omnidirectional stereo images without using any moving parts. Five randomized physical cards may be dealt to the player and to the dealer hand from a 53-card deck including a standard 52-card deck of playing cards and one joker, the joker and four deuces being designated as wild cards. The eyewear can further include polarized lenses oriented at either + or \u221245 degrees, matching the polarization of the liquid crystal display emission, and thus blocking ambient light not matching that polarization orientation. A striking base is attached to the guide rod near the end opposite to the hammerhead. The front-end POS software devices uses a holster that includes a docking station, sliding cradle for a mobile device, a card reader, and an infrared scanner to identify products and complete payment. It also discloses an efficient formula to make a mixed SAM that can greatly enhance the immobilization ability of the metal surface in SPR based techniques, which is good for the immobilization of HPV specific DNA probes used for the detection of different HPV genotypes.
