Method and apparatus for measurement alignment

A system for aligning measurements of a hostile environment, the system comprising:

• a measurement tool configured to measure characteristics of the hostile environment as a function of time, the measurement tool including at least a first recording device coupled to a first clock and operable to record the measured characteristics as a first time domain curve versus time measurements according to the first clock;
• and
• a second recording device coupled to a second clock, the second recording device being configured to receive measurements from the measurement tool and to record the measured characteristics as a second time domain curve versus time measurements according to the second clock wherein:
• the time domain curves are aligned and correlated after the measurements have been completed by identifying at least one event present in both the first and second time domain curve;
• and
• the time domain curves are corrected by adding one or more time offsets.

A method for aligning measurements of a hostile environment, the method comprising:

• receiving the measurements recorded by at least a first and a second recording device wherein at least the first recording device is disposed in the hostile environment;
• aligning time domain curves of the collected measurements after the measurements have been completed, by:
• identifying at least one event present in both the time domain curve of the first recording device and in the time domain curve of the second recording device;
• correlating the curves using one or more events recorded by at least the first and second recording devices;
• and
• correcting the curves by adding one or more time offsets.

A method for aligning measurements of a hostile environment, the method comprising:

• providing at least two clocks, wherein at least a first clock is in the hostile environment;
• measuring characteristics of the hostile environment and recording the characteristics as a time domain curve versus time recorded by each of the at least two clocks;
• after the measurements have been completed aligning time domain curves of the collected measurements recorded versus each of the at least two clocks, by:
• correlating the curves using one or more events identified in the time domain curves recorded by each clock;
• and
• if the curves do not correlate, correcting the curves by adding one or more time offsets.

A computer program product comprising:

• an input/output object operable to receive measurements recorded by at least a first and a second recording device and to produce a first and a second time domain curve each recorded versus a time measurement taken by a first and a second clock, respectively, wherein at least the first recording device is disposed in a hostile environment;
• an alignment object coupled to the input/output object the alignment object operable to align time domain curves of the collected measurements after the measurements have been completed by measuring:
• a correlation object coupled to the alignment object, the correlation object operable to correlate the curves using one or more events recorded by at least the first and second recording device;
• and
• a correction object coupled to the correlation object, the correction object operable to correct the curves by adding one or more time offsets, the correction object adding the one or more time offsets to the curves at a reset indication.

An apparatus configured to align time stamped measurements of a hostile environment recorded by at least two recording devices coupled to at least two synchronized clocks wherein at least a first clock is in the hostile environment, the apparatus comprising:

• means for measuring characteristics of the hostile environment;
• means for recording the measured characteristic versus time measurements of the first clock thereby producing a first time domain curve;
• means for recording the measured characteristic versus time measurements of a second clock thereby producing a second time domain curve;
• means for aligning time domain curves of the collected measurements after the measurements have been completed by invoking:
• means for correlating the curves using one or more events recorded by each clock;
• and
• means for correcting the curves by adding one or more time offsets.
