A presentation system comprises a screen, a laser pointer operated by a user to project laser beam on the screen, and an infrared light projector for emitting infrared light on the entire surface of the screen. The communication interface may act as a translator or protocol converter that reformats transmissions from one protocol to another based on protocol compatibility between the recipient and transmitting devices. The release mechanism has a compression spring positioned between the piston assembly and the bottom of the first cylindrical cutout and the compression spring. In operation, the lock is forced into the open position as the catches of the lens are forced to the backside of the latches, and as the lock closes, the latches are forced into the detents thereby securing the lens to the lock. Each unique record can be associated with a determined problem. A waveguide is coupled to the nanoparticle and able to receive the single photons.
