Abstract:
A method and system for reducing the effect of distortions on the baseline signal in an absorption spectroscopy system used for the detection or measurement of chemical species in a medium, whereby one or more correlations or convolutions are performed on the signal using a kernel function. The shape of the kernel function is chosen to reduce the influence of the baseline distortions on the processed measurand determination. The kernel function may also be chosen to enhance the absorption signal.
Abstract:
A device for sustaining a plasma in a torch is provided. In certain examples, the device comprises a first electrode configured to couple to a power source and constructed and arranged to provide a loop current along a radial plane of the torch. In some examples, the radial plane of the torch is substantially perpendicular to a longitudinal axis of the torch.

Abstract:
Naphthalene, benzene, toluene, xylene, and other volatile organic compounds VOCs have been identified as serious health hazards. Embodiments of the invention are directed to methods and apparatus for near-real-time in-situ detection and accumulated dose measurement of exposure to naphthalene vapor and other hazardous gaseous VOCs. The methods and apparatus employ excitation of fluorophors native or endogenous to compounds of interest using light sources emitting in the ultraviolet below 300 nm and measurement of native fluorescence emissions in distinct wavebands above the excitation wavelength. The apparatus of some embodiments are cell-phone-sized sensor/dosimeter “badges” to be worn by personnel potentially exposed to hazardous VOCs. The badge sensor of some embodiments provides both real time detection and data logging of exposure to naphthalene or other VOCs of interest from which both instantaneous and accumulated dose can be determined.
Abstract:
Systems and methods analyzing body fluids such as blood and bone marrow are disclosed. The systems and methods may utilize an improved technique for applying a monolayer of cells to a slide to generate a substantially uniform distribution of cells on the slide. Additionally aspects of the invention also relate to systems and methods for utilizing multi color microscopy for improving the quality of images captured by a light receiving device.
Abstract:
A method is provided for determining a visual range in daytime fog, the method (800) including a step of reading in and a step of ascertaining In the step of reading in, coordinates of at least one characteristic point of a brightness curve of a camera image of the fog are read in. The brightness curve represents brightness values of image points of the camera image along a reference axis of the camera image. In the step of ascertaining, a meteorological visual range in the camera image is ascertained using the coordinates, a meteorological contrast threshold, and a processing specification, in order to estimate the visual range in fog. The processing specification images location-dependent and/or direction-dependent scattered light through the fog in the camera image.
