A method for noninvasively measuring analytes such as blood glucose levels includes using a non-imaging OCT-based system to scan a two-dimensional area of biological tissue and gather data continuously during the scanning. Structures within the tissue where measured-analyte-induced changes to the OCT data dominate over changes induced by other analytes are identified by focusing on highly localized regions of the data curve produced from the OCT scan which correspond to discontinuities in the OCT data curve. The data from these localized regions then can be related to measured analyte levels.

The invention relates to a method and device for transmitting light over a fat fiber (1) between optical components (B1; B2) of an optical measuring device, which are provided at a launching end (C) and at an extraction end (R; K; O) of the fat fiber (1). Said measuring device comprises a guiding means for the curved rigid guidance of a first partial section (PQ; FGHI; IJ; FL; LM; MN) of the fat fiber (1). If the radius of curvature of the curved guidance falls below a first limit, the light beam profile of the fat fiber (1) is homogenized by a mode mixing. In order to diminish the effect on the transmitted light caused by a permitted change in position of the fat fiber (1), a stiffening means, which is rigidly connected to the guiding means, is provided for rigidly guiding a second partial section (QR; JK; NO) of the fat fiber (1). Said second partial section connects to the first partial section (PQ; FGH; IJ; FL; LM; MN) and extends essentially up to the optical component (B2) located at the extraction end (R; K; O), whereby the entire length of the first and second partial section is at least provided with a length that renders the extraction end (R; K; O) of the fat fiber (1) mechanically stable.

The present invention provides a write element for use in magnetic data recording system such as a computer disk drive. The write head utilizes the advantageous properties of high magnetic moments while overcoming the corrosion problems engendered by such materials. The write element includes a magnetic yoke constructed of first and second magnetic poles joined to one another at a back gap. While the majority of the poles are constructed of a high magnetic moment material a layer of relatively low magnetic moment material is provided on the first pole at the back gap portion of the first pole. The relatively low magnetic moment material prevents corrosion of the first pole during subsequent manufacturing of the write head. An electrically conductive coil passes through the magnetic yoke and is insulated there from. By passing an electrical current through the electrical coil, a magnetic flux is generated in the yoke. This magnetic flux then generates a magnetic fringing field in at a write gap of the yoke. The fringing field imparts magnetic data onto a recording medium passing thereby.

A communications system that uses electromagnetic waves. The communications system preferably operates in the millimeter-wave frequencies, and provides relatively high signal restoration and isolation. The communications system can use polarization diversity to increase the capacity of a channel. Isolation and restoration features in the transceivers eliminate or reduce the effects of precipitation and / or reflection and diffraction from objects, and thus is well-suited for an urban environment.The transceiver will select the proper antenna and signal path for optimal information throughput as the conditions in the propagation medium of the network vary.

A clock data recovery loop that can be used over a wide range of data rates and maintain second-order behavior includes a nonlinear (e.g., Bang-Bang) phase detector, a charge pump, an RC loop filter, and signal generator (e.g., a voltage controlled oscillator (VCO)). At low data rates, the loop may be operated with the charge pump and loop filter with stable second-order behavior, with the resistor R of the loop filter serving as a proportional path. A separate proportional path is also provided that provides phase detector output directly to a control input of the VCO, while the resistor R of the loop filter is also bypassed. As increasing data rates give rise to third-order effects, the separate proportional path may be activated to maintain second-order behavior.

A Plasma torch (10) for microwave induced plasma spectrochemical analysis of a sample includes a nozzle (30) in an inlet (18) for the main plasma gas flow between outer tube (12) and intermediate tube (14) of the torch (10). The nozzle (30) increases the gas flow velocity in the sheathing gas layer for the plasma which is provided by the gas flow from the annular gap (22) between the tubes (12 and 14). The increased velocity of the gas in the sheathing gas layer “stiffens” that layer and thus better confines the microwave induced plasma (such better confinement not being necessary for an ICP torch). Thus the torch is of improved durability for a microwave induced plasma compared to an ICP torch. The sample injection (inner) tube (16) may have a reduced diameter outlet at its end (34) which is substantially level with the end (35) of intermediate tube (14) to improve injection of a sample into the microwave induced plasma. The inlet end (26) of the sample injection tube (16) may include a heater (36) to assist in preventing blockages in tube (16) near its outlet end.

Methods and systems for non-intrusively detecting the existence of fissile materials in a container via the measurement of energetic prompt neutrons are disclosed. The methods and systems use the unique nature of the prompt neutron energy spectrum from photo-fission arising from the emission of neutrons from almost fully accelerated fragments to unambiguously identify fissile material. The angular distribution of the prompt neutrons from photo-fission and the energy distribution correlated to neutron angle relative to the photon beam are used to distinguish odd-even from even-even nuclei undergoing photo-fission. The independence of the neutron yield curve (yield as a function of electron beam energy or photon energy) on neutron energy also is also used to distinguish photo-fission from other processes such as (γ, n). Different beam geometries are used to detect localized samples of fissile material and also fissile materials dispersed as small fragments or thin sheets over broad regions. These signals from photo-fission are unique and allow the detection of any material in the actinide region of the nuclear periodic table.
