Eyeglasses having an integral case. The hydrophilic structure is configured to spread condensation. The storage locker also comprises a main door for covering the opening. A timing control part establishes mutually different frame timing offsets to the respective frames received from the subcarrier assigning part. The method and apparatus include multiple levels of clock gating control circuitry and a clock distribution network to generate a low-skew system clock signal, and generate a gated clock signal, from the system clock signal, and distribute the gated clock signal to a plurality of local logic circuits in the integrated circuit. One embodiment of the homogenizer comprises an entrance face positioned to receive light from the source, the entrance face having a first shape, a body configured to homogenize the received light and an exit face, the exit face parallel to the primary emitting face of the source.
