摘要:
Spatial frequency spectra from periodic, aperiodic and quasi-random structures in materials are shown and used to detect differences among objects via internal coding from the spatial frequencies. The method is applied to different grades of human tissues for a new form of histology and pathology, and to detect art forgeries and coding boxes, money and papers and gems. The randomness of material structures on surface and at depths near surface can be detected from the spatial spectrum. In tissue spectral features from normal to different stages of cancer in tissue for ex vivo and in vivo applications can be recognized by different spectral fingerprints content of the spatial frequency. Similarly, the painting for the strokes of artist is different. A new type of instrument is described to analyze materials as a Spatial Frequency Spectrometer.
摘要:
A rectal near infrared (NIR) scanning polarization imaging system uses NIR Photonic Prostatoscopy Analyzer (NIRPPA) for prostate cancer detection using light. The NIRPPA consists of a portable rectal NIR scanning polarization imaging unit and an optical fiber-based rectal probe capable of recording sets of 2D images of a prostate through rectum at different wavelengths and depths and obtaining a three dimensional (3D) image of the prostate and 3D locations of abnormal tissue inside the prostate. Diode lasers/light emission diodes (LEDs) with selected emitting wavelengths are used in the NIR spectral range from 650 nm to 2,400 nm corresponding to the four tissue optical windows (#I, 650 nm-950 nm; #II, 1,100 nm-1,350 nm; #III, 1,600 nm-1,870 nm; and #IV, 2,100 nm-2,300 nm). The fingerprint absorptions of water (H2O), Oxyhemoglobin (HbO2) and deoxyhemoglobin (Hb) in the prostate are used as native biomarkers for prostate cancer detection.

The present disclosure is directed to a system for controlling a plurality of managed devices. The system may involve a manageability services module adapted to facilitate communication between the plurality of managed devices and a central user located remotely from the plurality of managed devices. The system may also involve a manageability engine module that communicates with the manageability services module. The manageability engine module may have an element library storing parameters associated with the plurality of managed devices, and may be configured to perform a number of useful operations such as: facilitating communication between the managed devices and the manageability services module; discovering a new managed device; and collecting, aggregating and providing real time analytics on the data collected from the managed devices. A database may be used to store data collected by the manageability engine module.
摘要:
A method detects the degree of spoilage of food by exposing a food sample to an excitation wave having a first wavelength of about 340 nm or about 380 nm, wherein the excitation wave has a bandwidth of 40 nm or less. The excitation wave is permitted to interact with the food sample and return emission spectra. A detector detects the emission spectra. A predetermined threshold value is established which defines when a food sample is or is not spoiled. The emission spectra is analyzed at a second wavelength of about 400 nm, about 450 nm or about 530 nm to provide a test or measured value of the emission spectra indicative of the degree of spoilage of the food sample. Whether or not a food sample is spoiled beyond the predetermined threshold is determined by comparing the measured value to the predetermined threshold value.

A system for monitoring, controlling and optimizing power usage and cooling utilization within a data center infrastructure. The system may make use of a subsystem which is adapted to obtain real time information on both facility devices and information technology (IT) devices. The subsystem may be used to evaluate the real time information to provide an alert and diagnostic information with respect to at least one of the facility devices or at least one of the IT devices. The subsystem may also make use of a mechanism that provides real time control over at least one of the facility devices or at least one of the IT devices to optimize at least one of cooling utilization, power usage or performance of at least one of the facility devices or at least one of the IT devices.
