Abstract: A wearable device includes a measurement device having light emitting diodes (LEDs) measuring a physiological parameter. The measurement device modulates the LEDs to generate an optical beam having a near-infrared wavelength between 700-2500 nanometers. Lenses receive and deliver the optical beam to tissue, which reflects the optical beam to a receiver having spatially separated detectors coupled to analog-to-digital converters configured to generate receiver outputs. The receiver captures light while the LEDs are off, and reflected light from the tissue while the LEDs are on, to generate first and second signals, respectively. Signal-to-noise ratio is improved by differencing the first and second signals and by differencing the receiver outputs. The measurement device further improves signal-to-noise ratio of the reflected optical beam by increasing light intensity of the LEDs relative to an initial light intensity. The measurement device generates an output signal representing a non-invasive measurement on blood contained within the tissue.

Abstract: Provided are methods and systems for inspecting surfaces of various components, such as evaluating height deviations on these surfaces. A method involves aggregating inspection data from multiple line scanners into a combined data set. This combined data set represents a portion of the surface that is larger than the field of measurement any one of the scanners. Furthermore, each pair of adjacent scanners operate at different periods of time to avoid interference. Because operating periods are offset, surface portions scanned by the pair of adjacent scanners can overlap without interference. This overlap of the scanned portions ensures that the entire surface is analyzed. The position of scanners relative to the inspection surface may be changed in between the scans and, in some embodiments, even during the scan. This approach allows precise scanning of large surfaces.

Abstract: This invention provides a method of ranking a characteristic of a liquid sample by providing a test container [11] having a viewing port [16] to liquid contained therein and through which electronic image data of a defined body of liquid sample [20] in the container can be captured. This data is compared with an electronic data model containing comparison data with which the captured electronic image data can be compared to provide a ranking. The image is captured and the image data is electronically compared with the comparison data to provide a characteristic ranking of the sample.

Abstract: A device for recording an absorption spectrum of a fluid has a radiation source (1) that emits a radiation in a spectral range along a beam path (11), a measuring path (5), along which the radiation passes through the fluid and arranged in the beam path, a tunable Fabry-Perot interferometer (7), arranged in the beam path and transmitting radiation in the spectral range as a displaceable bandpass filter, and a detector (9, 35) measuring the intensity of the radiation in the spectral range. An etalon (3) is arranged for spectral modulation of radiation in the beam path and has a plurality of transmission maxima (17) in the spectral range. The bandpass filter, formed by the Fabry-Perot interferometer (7), is displaceable across the spectral range such that spectral modulation of the radiation by the etalon (3) is measured by the detector (9, 35) as a modulation of radiation intensity over time.
