International Classification:

H04J 14/00

US Classification:

398 45, 398 50, 398 51, 398 54, 398 56

Abstract:

A hierarchical and distributed control architecture for managing an optical communications network. The architecture includes a line card manager level for managing individual line cards in an optical switch, a node manager level for managing multiple line cards in an optical switch/node, and a network management system level for managing multiple optical switches/nodes in a network. An event manager at the node manager level enables software components that are running at the node manager to register for and receive events, and to post events. The events may be triggered, e. g. , by a change in a status of the switch, or an alarm condition. Control architecture functionalities include signaling, routing, protection switching and network management. Furthermore, the network management function includes a topology manager, a performance manager, a connection manager, a fault detection manager, and a configuration manager.

International Classification:

G01J 3/30

US Classification:

356317, 2504591

Abstract:

Bones, bone fragments, and shell fragments on or near the surface of processed animal flesh may be detected by detecting their fluorescent emissions. The surface of the flesh is illuminated with UV or visible light to elicit fluorescence of animal bones or shells, and the fluorescent light emissions are measured at first and second different wavelengths, which wavelengths are selected to yield a substantial difference between the ratio or subtractive difference for bones or shells and the ratio or subtractive difference for animal flesh. The ratio and/or subtractive difference of the fluorescent light emissions at the first and second wavelengths is calculated, and the presence of bone, bone fragment, or shell fragment is determined therefrom.

International Classification:

C12Q 1/00

US Classification:

435 4, 435 34, 435 29, 356317

Abstract:

Time-dependent differences in fluorescence responses of normal surfaces of the fruit or vegetable as opposed to surfaces which are contaminated with feces, may be used for improved detection of feces-contaminated fruits and vegetables. In this process, the surface of a fruit or vegetable which contains a native chlorophyll is illuminated with a pulse of UV or visible light having a wavelength effective to elicit fluorescence of feces of a plant consuming animal. The intensity of fluorescent light emissions from the surface are measured at one or more wavelengths characteristic of the emission spectra of chlorophyll or its degradation products, at a nanosecond-scale time period or window which is after the peak emission of the native chlorophyll of the fruit or vegetable. The presence of fecal contamination is determined by comparing this measured intensity to a threshold value of the intensity of fluorescent light emissions for a non-feces contaminated control of the same fruit or vegetable measured at substantially the same conditions, substantially the same said time period, and at substantially the same said wavelengths. A determination that the measured intensity of the fluorescent light emissions is significantly greater than the threshold value is an indication of the presence of fecal material on the surface of the fruit or vegetable.

International Classification:

H04N 7/18

US Classification:

348143, 348 89

Abstract:

The hand-held inspection tool enhances the ability of an on-site inspector to detect and communicate the presence of contamination on an object or in an area. An on-site inspector directs an excitation light in the sensing head of the tool into an area of interest. If the targeted contamination is present, the excitation light causes the contamination to emit fluorescence. The emitted fluorescent light passes through a narrow spectral band-pass video camera filter and is detected by a video camera mounted in the tool sensing head. The video camera transmits the image to a display visible to the on-site inspector. The invention also includes a means of recording, documenting, and wirelessly communicating the inspection process so that remotely located personnel can view the inspection, and respond to the inspection findings in real time.

International Classification:

G01J 3/44

US Classification:

356301

Abstract:

System and method for determining the presence of a contaminant in a sample using Raman spectroscopic data. The sample may be food or feed and the contaminant may be melamine. The sample is illuminated with substantially monochromatic light to produce Raman scattered photons. The Raman scattered photons are collected to generate Raman spectroscopic data. The Raman spectroscopic data may comprise at least one of a Raman spectrum and a spatially accurate wavelength resolved Raman image. The Raman spectroscopic data is analyzed to determine the presence or absence of a contaminant in a sample. The concentration of the contaminant in the sample can also be determined by using a ratio algorithm.
