The present invention discloses an optical device able to luminesce, whereby the optical device comprises, inter alia, a luminescent source that is directly or indirectly mechanically coupled to a low-order mode waveguide, such that light emitting from the luminescent source is optically coupled into the low-order mode waveguide. The systems and methods involve using a correlation factor or mathematical formula to assist users in selecting lottery numbers. The impedance detect circuit detects an external impedance. A second audio andor video fingerprint is periodically transmitted to a server from the first device.
