Abstract: System and method to use position information about a power supply unit (PSU) within a system for status reporting or control. The system may have multiple slots into which the PSU may be installed, and each of multiple PSUs installed may sense position information, such as an indication of the slot into which it is installed. A controller may receive the position information in connection with status information such that faults or other events associated with a PSU may be reported to a system operator in connection with a position of the affected PSU. The controller may determine adjustments to operating parameters of the PSUs that are impacted by position and may direct commends to the appropriate PSU based on the position information.

Abstract: The invention discloses a two-mode Raman optical projection tomography system. Samples are irradiated by the laser beam after the beam being expanded by beam expander. Optical signal of each mode will be separated by the beam splitter. Sparse sampling method is used for signal collection. Optical transmission projection signal acquisition module collects transmitted light of samples to form optical projection image. Multi-spectral Raman scattering signal acquisition module collects Raman scattering light produced by samples. Background noise is removed from the collected data. Sparse sampling data are reconstructed by using algebraic reconstruction method (ART) based on TV minimization. The three-dimensional structure image obtained by reconstruction and the three-dimensional chemical compositions image are fused to obtain the three-dimensional volume image with multiple information.
