  • Publication number: 20080139958
    Abstract: A practical method for estimating cardiac output and pulmonary artery wedge pressure with good accuracy is provided. The present invention provides a method for estimating the impedance arising from solid tissue by determining the impedance at the intersection between the line of identity and the extrapolated regression line, where the regression line is obtained by linearly regressing the maximum value to the minimum value of the impedance signal of each of multiple data sets, where each data set contains the maximum value and the minimum value of the impedance signal during one cardiac cycle, where impedance signal is obtained between a can electrode implanted in the left thoracic wall and an electrode inserted into the coronary vein, over a specific period of time following the infusion of hypertonic saline into the pulmonary circulation.

  • Patent number: 7258595
    Abstract: A polishing apparatus comprises a polishing table having a polishing surface and a top ring for holding a substrate to be polished, in which the substrate when held by the top ring is pressed against the polishing surface of the polishing table and thus polished. A capacitance type sensor and/or an eddy-current type sensor is disposed at one or more location(s) in the vicinity of the top ring. The capacitance type sensor detects escaping of the substrate to be polished based on a change in capacitance between the capacitance type sensor and a top surface of the polishing table. The eddy-current type sensor detects escaping of the substrate to be polished based on a change in electrical resistance between the eddy-current type sensor and the top surface of the polishing table.
