Title: System for precharging a dc link in a variable speed drive
Inventor: SCHNETZKA HAROLD R
IPC: H02H9/00
Filed: 2006-02-09
Abstract: A variable speed drive (104) with a converter (202) that is controllable to precharge a DC link (204) is provided. The variable speed drive (104) also includes an inverter (206). The converter (202) converts a fixed line frequency, fixed line voltage AC power from an AC power source (102) into DC  power. The DC link (204) filters the DC power from the converter (202).  Finally, the inverter (206) is connected in parallel with the DC link (204) and converts the DC power from the DC link (204) into a variable frequency, variable voltage AC power. The converter (202) includes a plurality of pairs of power switches, wherein each pair of power switches includes a reverse blocking power switch arrangement (454, 650A, 652B) connected in anti-parallel to another reverse blocking power switch arrangement (456, 652A, 650B).  Alternatively, each pair of power switches includes a reverse blocking power switch (454) connected in anti-parallel with a silicon carbide controlled rectifier (500).

Title: Methods and apparatus for noninvasive determinations of analytes
Inventor: ROBINSON RIES M
IPC: B08B7/00
Filed: 2006-02-09
Abstract: The present invention provides methods and apparatuses for accurate noninvasive determination of tissue (208) properties. Some embodiments of the present invention comprise an optical sampler (221) having an illumination subsyste (201), adapted to communicate light having a first polarization (205) to a tissue surface (208); a collection subsystem (222), adapted to collect light having a second polarization communicated from the tissue (209) after interaction with the tissue (208); wherein the first polarization is different from the second polarization. The difference in the polarizations can discourage collection of light specularly reflected (209) from the tissue surface (208), and can encourage preferential collection of light that has interacted with a desired depth of penetration or path length distribution in the tissue. The differen polarizations can, as examples, be linear polarizations with an angle between, or elliptical polarizations of different handedness.

Filed: 2006-11-02
Abstract: A video display for digitized video data interpolates values between time samples, such as luminance over a horizontal line or over an average of all the horizontal lines in a video signal, so as to produce a digitally plotted test display resembling the continuous line display of an oscilloscope. A digital impulse response filter has stored coefficients that contribute as factors to the values of interpolated data points to fill the line display between sample values. Instead of changing the coefficients to produce variations interpolating the output between sample values, the coefficients are held constant and a delay factor is varied to alter the extent to which the respective coefficients and sample values interact and contribute to the interpolated values.

Abstract: Apparatus and associated systems and methods may relate to a process for supplying unidirectional current to a load, controlling a reverse electromotive force (REMF), capturing inductive energy from the load, and supplying the captured inductive energy to the load. In an illustrative example, an operating cycle may include a sequence of operations. First, inductive energy captured from the load on a previous cycle may be supplied to the load. Second, energy may be supplied to the load from an external power source. Third, a REMF voltage may be substantially controlled upon disconnecting the power source from the load. Fourth, the load current may be brought to zero by capturing the inductive energy for use on a subsequent cycle. In some embodiments, a single power stage may supply a DC inductive load, or a pair of power stages may be operated to supply bidirectional current to an AC load.
