Various techniques for synchronizing illumination with an audio signal are disclosed. According to one aspect of the techniques, an audio signal continuously is received and processed one phase or period at a time in an analyzing or detecting unit. From one phase of the audio signal, a set of light controlling parameters are determined from a look-up-table. These light controlling parameters are used to adjust duty cycles of square waves used to drive a plurality of light sources such that the illumination produced is in accordance with the audio signal.

Device and method for synchronizing illumination with music

Techniques for a simple file system for facilitating file transmission are disclosed. According to one aspect of the techniques, a storage device comprises a memory, a creation module, a status record module and a data reading/writing module. The creation module creates a parameter block, a file allocated table, a root directory and a data area in the memory. The starting address of the data area is calculated according to parameters in the parameter block. The status record module stores a last writing address of a last writing access to the memory. The data reading/writing module reads data from the data area according to the starting address and the last writing address.
