An semiconductor device comprising a first semiconductor die and a leadframe. The waveguide is doped with gold or platinum such that when a drive voltage is turned off, the minority charge carriers rapidly annihilate because gold doping reduces the minority carrier lifetime, which improves transient characteristics of the optical device. The attachment portion has hook material attachment means on one side for direct attachment to adjacent sock material. The output value may represent the known andor unknown values of the attribute. A sound source for the musical signal can also be provided as part of the waterproof recreational audio device. Optionally, there are multiple sets of community cards.
