This disclosure describes a more efficient and configurable power allocation scheme for redundant power supply systems used in network switches. The lifting steps can provide a lossless compression and a lossy compression directly from lossless compression while the integer-to-integer adaptive four-stage lifting wavelet transform provides the lossless compression with improved performance. for distinguishing flames from other hot bodies, examines the correlation between adjacent pixels of an array viewing the fluid and particularly the proportion of negative correlation in the presence of strong positive correlation. The external content can be accessed in real time or downloaded and stored within the system for later access at the convenience of the user.
