Abstract: Methods for using modified single wall carbon nanotubes (“SWCNTs”) to detect presence and/or concentration of a gas component, such as a halogen (e.g., Cl2), hydrogen halides (e.g., HCl), a hydrocarbon (e.g., CnH2n+2), an alcohol, an aldehyde or a ketone, to which an unmodified SWCNT is substantially non-reactive. In a first embodiment, a connected network of SWCNTs is coated with a selected polymer, such as chlorosulfonated polyethylene, hydroxypropyl cellulose, polystyrene and/or polyvinylalcohol, and change in an electrical parameter or response value (e.g., conductance, current, voltage difference or resistance) of the coated versus uncoated SWCNT networks is analyzed. In a second embodiment, the network is doped with a transition element, such as Pd, Pt, Rh, Ir, Ru, Os and/or Au, and change in an electrical parameter value is again analyzed.

Abstract: A method of processing Fourier Transform Mass Spectrometry (FTMS) data includes performing a Fourier Transform of a part of a time domain transient and identifying from that transformed data signal peaks representative of the presence of ions. After peak identification, the full transient is then transformed, and the peaks identified in the partial transient transform are used to locate true peaks in the transformed full transient. The number of ‘false’ peaks resulting from random noise has been found to correlate to the resolution, so that using a partial transient to identify true peaks reduces the risk of false peaks being included; nevertheless this information can then be applied to the full data set when transformed. As an alternative, different parts of the full data set can be transformed and then correlated; because any noise will be random, false peaks should occur at different places in the two partial transforms.

Abstract: A method of analyzing data from a mass spectrometer provides data-dependent acquisition. An extracted ion chromatogram (XIC) is created for each m/z data point of mass spectral scans and the XIC for each m/z data point are correlated to a model function to obtain a XIC correlation value. A weighting function is applied to the XIC correlation value to obtain a current weighted intensity for each m/z point, which is used to reconstruct a weighted mass spectrum. The value or range of intensities of interest of the weighted intensity data or raw data is transformed from the time domain into the frequency domain, and the transformed data is used to make a real-time decision for the data-dependent acquisition. The data-dependent acquisition can be the performance of tandem mass spectrometry. A sample processing apparatus receives the sample and a computer readable medium provides instructions to the apparatus.

Abstract: A meter is provided that includes an improved user interface that enables the user to take a specific action, leading them directly to data input options. Such a user interface could be used to input first selected information, such as whether a test was premeal or postmeal, immediately after receiving a result. Optionally, the user interface may include the ability to add an additional comment after inputting the first selected information. Provision of such a user interface would facilitate simpler capture of the first selected information each time the user performs a test, leading to an enhanced understanding of a patient's level of glycemic control. Designing a user interface to enable first selected information to be entered by a user directly after receiving a result is more likely to engage a patient by making it easy and simple to enter important information. This may enable capture of the information thought to be most pertinent e.g.

In yet another embodiment, the collection of transients is terminated when a threshold signal to noise ratio is attained.

Abstract: A calculated vertical velocity sensor signal is determined from a recorded pressure sensor signal. A constructed vertical velocity sensor signal is determined as a linear combination of the calculated vertical velocity sensor signal and a recorded vertical velocity sensor signal in dual-sensor seismic streamer data, using a mixture coefficient as a proportionality constant. An upgoing pressure wavefield component is determined as one half of a difference of the recorded pressure sensor signal and the constructed vertical velocity sensor signal, as a function of the mixture coefficient. An error in the upgoing pressure wavefield component is determined by propagating errors in the recorded pressure sensor signal and constructed vertical velocity sensor signal terms. A value of the mixture coefficient is determined that minimizes the error in the upgoing pressure wavefield component.
