Temperature analysis with voltage-current time differential operation of electrochemical sensors

Title: Temperature analysis with voltage-current time differential operation of electrochemical sensors

A method for temperature analysis of a gas stream. The method includes identifying a temperature parameter of an affected waveform signal. The method also includes calculating a change in the temperature parameter by comparing the affected waveform signal with an original waveform signal. The method also includes generating a value from the calculated change which corresponds to the temperature of the gas stream.

Gas stream analysis using voltage-current time differential operation of electrochemical sensors

Patent Woo, Leta Yar-Li ; Glass, Robert Scott ; Fitzpatrick, Joseph Jay ; Wang, Gangqiang ; Henderson, Brett Tamatea ; Lourdhusamy, Anthoniraj ; Steppan, James John ; Allmendinger, Klaus Karl

A method for analysis of a gas stream. The method includes identifying an affected region of an affected waveform signal corresponding to at least one characteristic of the gas stream. The method also includes calculating a voltage-current time differential between the affected region of the affected waveform signal and a corresponding region of an original waveform signal. The affected region and the corresponding region of the waveform signals have a sensitivity specific to the at least one characteristic of the gas stream. The method also includes generating a value for the at least one characteristic of the gas stream basedmore »« less

Electrochemical sensing using voltage-current time differential

Patent Woo, Leta Yar-Li ; Glass, Robert Scott ; Fitzpatrick, Joseph Jay ; Wang, Gangqiang ; Henderson, Brett Tamatea ; Lourdhusamy, Anthoniraj ; Steppan, James John ; Allmendinger, Klaus Karl

A device for signal processing. The device includes a signal generator, a signal detector, and a processor. The signal generator generates an original waveform. The signal detector detects an affected waveform. The processor is coupled to the signal detector. The processor receives the affected waveform from the signal detector. The processor also compares at least one portion of the affected waveform with the original waveform. The processor also determines a difference between the affected waveform and the original waveform. The processor also determines a value corresponding to a unique portion of the determined difference between the original and affected waveforms.more »« less

Patent Degtiarenko, Pavel V ; Popov, Vladimir E

A first stage electronic system for receiving charge or current from voltage-controlled sensors or detectors that includes a low input impedance current receiver/converter device (for example, a transimpedance amplifier), which is directly coupled to the sensor output, a source of bias voltage, and the device's power supply (or supplies), which use the biased voltage point as a baseline.

Non-contact passive temperature measuring system and method of operation using micro-mechanical sensors

Patent Thundat, Thomas G. ; Oden, Patrick I. ; Datskos, Panagiotis G.

A non-contact infrared thermometer measures target temperatures remotely without requiring the ratio of the target size to the target distance to the thermometer. A collection means collects and focusses target IR radiation on an IR detector. The detector measures thermal energy of the target over a spectrum using micromechanical sensors. A processor means calculates the collected thermal energy in at least two different spectral regions using a first algorithm in program form and further calculates the ratio of the thermal energy in the at least two different spectral regions to obtain the target temperature independent of the target size, distancemore »« less
