<title><![CDATA[Overcoming space charge effects in ion cyclotron resonance mass spectrometers]]></title>
<link>http://www.freepatentsonline.com/7615743.html</link>
<description><![CDATA[In an ion cyclotron resonance mass spectrometer in which ions are trapped axially by applying electrical potentials to a pattern of electrode elements to produce an inhomogeneous alternating radio-frequency electric field with a repulsive effect, an additional electrostatic ion-attracting field is superimposed on the repulsive electric field. The voltage of the ion-attracting field is adjusted to compensate for a cyclotron frequency shift of the ions caused by the ion space charge. The voltage of the ion-attracting field can be adjusted so that the ion cyclotron frequency of all ions becomes independent of the number of ions inside the spectrometer.]]></description>

<title><![CDATA[Method for separating a minute sample from a work piece]]></title>
<link>http://www.freepatentsonline.com/7615745.html</link>
<description><![CDATA[The invention pertains to a method for separating a minute sample ( 1 ) from a work piece ( 2 ). Such a method is routinely used in the semiconductor industry to obtain samples from wafers to be inspected in a TEM. It occurred to the inventor that approximately 20% of the obtained samples could not be properly finished (thinned) due to a misalignment of specimen carrier ( 6 ) and sample. It turned out that this misalignment is caused by the specimen carrier contacting the sample prior to welding. By not contacting the sample while welding, but leaving a small gap between specimen carrier and sample, this misalignment is avoided. To avoid movement of the specimen carrier during welding, due to e.g. vibration, the specimen carrier can be landed on the wafer on a position ( 8 ) close to the sample.]]></description>

<title><![CDATA[Measurement of light fragment ions with ion traps]]></title>
<link>http://www.freepatentsonline.com/7615742.html</link>
<description><![CDATA[The invention relates to methods for the measurement of fragment ion spectra in ion trap mass spectrometers in which fragment ions below a cut-off mass cannot normally be measured. The invention consists in measuring mass spectra including light fragment ions by briefly conducting the collisionally induced fragmentation—which is always brought about by a large number of collisions—at an unusual high RF storage voltage, which produces collisions more energetically than by conventional fragmentation, and then switching the RF voltage to a low RF voltage in a fast but controlled procedure. In this way light fragment ions are produced by double cleavages from metastable fragment ions with a certain half-life time. Since the cut-off mass for the storage capability is proportional to the RF storage voltage, reducing the RF storage voltage means that the light fragment ions can also be kept and measured in the ion trap.]]></description>

<description><![CDATA[Computation-saving techniques and stability-adding techniques provide for fast, accurate reconstructions of a time series of images involving large-scale 3D problems, such as real-time image recovery in an optical tomography imaging system. A system equation for a target medium ( 116 ) such as tissue is solved using a Normalized Difference Method (NDM) ( 250 ). Because of the inherent stability of the NDM solutions, a weight matrix (W) of the system equation can be provided for a given point in a time series ( 220 ), then reused without recalculation at subsequent points. Further savings are achieved by decomposing W using singular value decomposition or direct matrix decomposition, transforming it to reduce its dimensions, and/or scaling it to achieve a more stable numerical solution. Values of measured energy ( 112 ) emerging from the target medium are back-substituted into the system equation for the different points to obtain the target medium properties.]]></description>

<description><![CDATA[In a process for the quantitative optical analysis of fluorescently labelled biological cells  5 , a cell layer on a transparent support at the bottom  2  of a reaction vessel  1  is in contact with a solution  3  containing the fluorescent dye  4 . The sensitivity of analytical detection can be considerably improved if to the fluorescent dye  4  already present in addition a masking dye  9 , which absorbs the excitation light  6  for the fluorescent dye  4  and/or its emission light  7 , is added to the solution  3  and/or if a separating layer  10  permeable to the solution and absorbing and/or reflecting the excitation light  6  or the emission light  7  is applied to the cell layer at the bottom  2 . This process can also be used for improving the sensitivity in the quantitative optical analysis of a luminescent biological cell layer. The separating layer  10  must in this case be composed such that it has a high power of reflection for the luminescent light  11 . Analogously, these process principles can also be used in receptor studies for the masking of the interfering background radiation in the quantitative optical analysis of fluorescently or luminescently labelled reaction components. In this case, a receptor layer  12  at the bottom  2  of a reaction vessel  1  is in contact with a solution (supernatant  3 ) in which a fluorescent or luminescent ligand  13  is dissolved. The sensitivity and accuracy of the analytical detection can be considerably improved here if a masking dye  9  which absorbs the excitation light  6  for the fluorescent dye and/or its emission light or (in the case of luminescent ligands) the luminescent light is added to the supernatant  3 . Instead of the masking dye in the solution  3  or optionally as an additional measure, a separating layer  10  permeable to the solution  3  and absorbing and/or reflecting the excitation light  6  and/or the emission light or the luminescent light can be applied to the cell or receptor layer  12  at the bottom  2.]]></description>
