The results of the discrete Fourier transform are multiplied by a complex phase adjustment term as a function of distance from the sampling locations to the DUT to translate the measured field component values back to the locations on the surface of the DUT.

Abstract: A system and method for measuring near field information of a device under test (DUT) uses a reference probe and a measurement probe that are configured to sense a field. A probe calibration factor is used to determine corresponding field values for signals from the measurement probe at sampling locations about the DUT. The probe calibration factor is derived from measured signals about a conductive trace using a probe and simulated field information for the conductive trace when subjected to a simulated reference signal.

Abstract: The scientific characterization of cellular contractility and cell movement, such as muscle function in particular is, to a large extent, carried out on intact tissue preparations for example using whole intact muscles from animals. Typical indices of muscle function may include isometric force, contractility under external force (load) and spatio-temporal determination of internal calcium concentration under strictly controlled conditions of length and applied force. The major advance of the described apparatus is that the common characterization of cellular contractility can be performed on a single cell rather than an entire tissue or whole animal. As such the apparatus described improves on and eliminates known limitations of currently considered state-of-the-art approaches.

Abstract: A light emitting diode (LED) based detection system is employed for spectroscopy based applications. LEDs are used as monochromatic light sources for applications at specific and pre-defined wavelengths. Spectrographic information is generated using LEDs of different wavelengths ranging from 260 nm to 1400 nm. Multiple wavelength information is generated by coupling light from each LED into an intensity and mode mixing fiber bundle. A dual beam approach of using a reference and a sample photodiode ensures automatic drift correction. Interference filters at the LED input fiber reduce the spectral bandwidth of the monochromatic light emission to a useful 10 nm bandwidth by cutting off the LEDs trailing emission distribution allowing for absorbance measurements similar to typical spectrometers.

The resin solvent mixture is heated to a predetermined temperature above room temperature. The amorphous fluoropolymer resin is dissolved in a heated solvent, and the liquid coating solution is applied to a substrate. The solvent is then removed from the applied liquid coating solution. The coating technique may be employed in connection with liquid core waveguides.
