  • Patent number: 10324624
    Abstract: According to examples, an apparatus may include a processor and a non-transitory computer readable medium storing instructions that cause the processor to classify files stored on a source storage into files for deletion and files for migration based on a storage policy and meta-data, generate aliases to link the files classified for migration to a location on a target storage, copy the files classified for migration from the source storage to the linked location on the target storage, and determine whether the files copied onto the target storage are identical to the files classified for migration on the source storage using a digital key. In response to a determination that the copied files are identical to the files classified for migration, the processor may activate the generated aliases and may decommission the source storage.

  • Publication number: 20070057211
    Abstract: In the systems and methods of the present invention a multifocal multiphoton imaging system has a signal to noise ratio (SNR) that is reduced by over an order of magnitude at imaging depth equal to twice the mean free path scattering length of the specimen. An MMM system based on an area detector such as a multianode photomultiplier tube (MAPMT) that is optimized for high-speed tissue imaging. The specimen is raster-scanned with an array of excitation light beams. The emission photons from the array of excitation foci are collected simultaneously by a MAPMT and the signals from each anode are detected using high sensitivity, low noise single photon counting circuits. An image is formed by the temporal encoding of the integrated signal with a raster scanning pattern. A deconvolution procedure taking account of the spatial distribution and the raster temporal encoding of collected photons can be used to improve decay coefficient.

  • Patent number: 5814820
    Abstract: A scanning fluorescence lifetime microscope measures modulation and phase in fluorescence emission stimulated by spatially overlapped pump and probe beams operating at different frequencies. A pump laser modulated at a first frequency is focused onto a diffraction limited spot to excite a fluorescent sample under study. Simultaneously, a probe laser modulated at a second frequency is focused onto the same spot to induce a stimulated fluorescence emission in response to the optically combined output of the pump and probe laser light. Fluorescence emitted from the sample produces a cross-correlation signal which is dependent upon the spatial overlapping of the pump and probe beams at the focal point thereby producing a beneficial axial sectioning effect. Choosing a small differency frequency between the modulation of the first and second laser sources produces a low frequency cross correlation signal even when the modulation frequencies of the pump and probe lasers are very high.
