In one implementation, a system caches view custom options in a framework to support web-based applications. The light-recycling illumination system includes a light source that is enclosed within a light-recycling cavity. The cyclic molecule is cyclodextrin, and each of all or a part of the hydroxyl groups in the cyclodextrin is modified with a hydrophobic modification group. The circuitry monitors the phase relationship and adjusts the inverter frequency, such as by adjusting voltage controlled oscillator, so that the phase relationship is maintained at a predetermined relationship. The load of print media is transmitted to the hoist drum, from which it is further transmitted to the spring through the shaft.
