Methods and apparatus are provided for managing data in a hierarchal storage subsystem. A plurality of volumes is designated as a storage group for Level 0 storage; a high threshold is established for the storage group; space is allocated for a data set to a volume of the storage group, storing the data set to the volume; the high threshold is compared with a total amount of space consumed by all data sets stored to volumes in the storage group; and data sets are migrated from the storage group to a Level 1 storage if the high threshold is less than or equal to the total amount of space used by all of the data sets stored to volumes in the storage group. Optionally, high threshold are assigned to each storage group and, when the space used in a storage group reaches or exceeds the high threshold, migration of data will begin from volumes in the storage group, beginning with the volume having the least free space. Thus, contention between migration and space allocation is reduced. Also optionally, when a volume is selected for migration, a flag is set which prevents space in the volume from being allocated to new data sets. Upon completion of the migration, the flag is cleared and allocation is allowed. Thus, contention between migration and space allocation is avoided.

Protocols for OFDM/OFDMA/SC-FDMA based wireless networks provide adaptive inter-cell interference management without explicit spectrum or frequency planning. Base stations and mobile stations acquire information about subcarrier allocation from a handoff protocol. The mobile stations can also acquire this information using cognitive sensing. Cognitive sensing can be rewarded by the base station. Using this information, subcarriers can be allocated randomly, with blind optimization, or by joint optimization. The stations can use game theory to select among the different optimization strategies.

A color light projector utilizes color light-emitting diodes (120, 140_Y, and 140_Z or 320_X, 320_Y, and 320_Z) as light sources. Digital light modulators (124 and 144 or 324_X, 324_Y, and 324_Z), typically digital micromirror devices, perform reflective color light modulation. In one implementation, light of three or more colors is modulated efficiently with only two modulators so that the component count and cost are low. In another implementation, each of three different colors is modulated with a separate modulator. A beam combiner (104 or 304) combines the digitally modulated beams (136* and 156* or 336_X*, 336_Y*, and 336_Z*) of color light to produce a composite beam (166 or 346) of the different colors. A projection lens device (106) projects the composite color beam.
