Title: Distributed fiber optic sensor using clad material light backscattering
Inventor: BOIARSKI ANTHONY A
IPC: G01N21/43
Filed: 1992-04-14
Abstract: A distributed fiber-optic sensor is obtained by using cladding (14) that produces a change in the intensity of backscattered light (20) in the optical fiber in response to a change in the environment of the cladding (14). A sensing means such as an optical time domain refractometer is used to determine the change in intensity of the backscatter light (20) at a specific location along the fiber. The change in intensity of the backscattered light (20) is caused by overall changes in the amount of light in the cladding (14) and changes in the number, size or both of the refractive index inhomogeneities in the cladding (14). These inhomogeneities can be, but are not limited to, composition variations, density variations of the same composition, phase separations, voids, or particulate inclusions.

Abstract: A rigidized fibre filter element is produced from a precursor  fibre  web  according  to  various  methods.    The precursor fibre web contains heat-shrinkable fibres or binder fibres  or  both.    The  web  is  exposed  to  temperatures sufficiently elevated to cause shrinkage of the fibres or melting of the binder.   After cooling the web, the filter elements produced are self-supporting, and may have densities up to 500 kg/m3 to improve filtration while retaining good functional characteristics for operating pressure drop and air permeability.    Rigidized  fibre  filter  elements  can  be constructed of one material,  and thus may be suitable for recycling.

Title: Method of detecting cancer by measuring lipid-peroxidation using nmr
Inventor: FOSSEL ERIC T
IPC: A61B5/055
Filed: 1991-07-23
Abstract: A technique and an apparatus are disclosed for the detection of cancer using nuclear magnetic resonance (NMR). Specifically, NMR  parameters for protons of lipid methyl and/or methylene groups are determined and compared against a corresponding value for healthy patients. Suppression of the water proton signal is employed where necessary in order to obtain a suitable spectrum for the non-water component protons. In the event that a positive reading is obtained, the level of plasma triglycerides is determined and if it is high, the patient's bodily fluid sample is further subjected to second proton nuclear magnetic spectroscopy. The area or the intensity of the portion correlating to 2.0 and 2.8 ppm of the resonance line generated in the second NMR is measured which discriminates between true and false positive results from the proton NMR reading and determines the presence or absence of cancer in the patient.
