Abstract

The method and apparatus of the invention effects compression of an analog electrical signal (e.g., representing an interferogram) by introducing into it a component that is a cubic function thereof, normally as a nonlinear negative signal in a feedback loop of an Op Amp. The compressed signal will most desirably be digitized and then digitally decompressed so as to produce a signal that emulates the original.

Method and apparatus for determining a normal combustion characteristic for an internal combustion engine from an accelerometer signal

Patent Huang, Jian; Ancimer, Richard; Cheung, Duran

The method comprises operating a calibration engine, and collecting combustion characteristic data and reference accelerometer signals, which are correlated with each other and stored in a calibration table. The calibration table can be used by an engine to determine a real-time normal combustion characteristic when the engine is operating by collecting a real-time accelerometer sensor signal and cross correlating with the correlated data stored in the calibration table. Accordingly, the apparatus comprises a calibration engine comprising a calibration sensor, a reference accelerometer sensor and a data storage device for storing the collected calibration data that is correlated with the collectedmore » « less

Method and apparatus for signal processing in a sensor system for use in spectroscopy

Patent O'Connor, Paul [Bellport, NY]; DeGeronimo, Gianluigi [Nesconset, NY]; Grosholz, Joseph [Natrona Heights, PA]

A method for processing pulses arriving randomly in time on at least one channel using multiple peak detectors includes asynchronously selecting a non-busy peak detector (PD) in response to a pulse-generated trigger signal, connecting the channel to the selected PD in response to the trigger signal, and detecting a pulse peak amplitude. Amplitude and time of arrival data are output in first-in first-out (FIFO) sequence. An apparatus includes trigger comparators to generate the trigger signal for the pulse-receiving channel, PDs, a switch for connecting the channel to the selected PD, and logic circuitry which maintains the write pointer. Also included,more » « less

Method and apparatus for automatically detecting patterns in digital point-ordered signals

Patent Brudnoy, David M [Albany, NY]

The present invention is a method and system for detecting a physical feature of a test piece by detecting a pattern in a signal representing data from inspection of the test piece. The pattern is detected by automated additive decomposition of a digital point-ordered signal which represents the data. The present invention can properly handle a non-periodic signal. A physical parameter of the test piece is measured. A digital point-ordered signal representative of the measured physical parameter is generated. The digital point-ordered signal is decomposed into a baseline signal, a background noise signal, and a peaks/troughs signal. The peaks/troughs frommore » « less

Method and apparatus for improving resolution in spectrometers processing output steps from non-ideal signal sources

Patent Warburton, William K.; Momayezi, Michael

A method and apparatus for processing step-like output signals (primary signals) generated by non-ideal, for example, nominally single-pole ("N-1P ") devices. An exemplary method includes creating a set of secondary signals by directing the primary signal along a plurality of signal paths to a signal summation point, summing the secondary signals reaching the signal summation point after propagating along the signal paths to provide a summed signal, performing a filtering or delaying operation in at least one of said signal paths so that the secondary signals reaching said summing point have a defined time correlation with respect to one another,more » « less

Method and apparatus for correcting eddy current signal voltage for temperature effects

Patent Kustra, Thomas A [N. Huntingdon, PA]; Caffarel, Alfred J [Pittsburgh, PA]

An apparatus and method for measuring physical characteristics of an electrically conductive material by the use of eddy-current techniques and compensating measurement errors caused by changes in temperature includes a switching arrangement connected between primary and reference coils of an eddy-current probe which allows the probe to be selectively connected between an eddy current output oscilloscope and a digital ohm-meter for measuring the resistances of the primary and reference coils substantially at the time of eddy current measurement. In this way, changes in resistance due to temperature effects can be completely taken into account in determining the true error inmore » « less
