Patent ID: 7970566

Claim:
One or more computer-readable storage media comprising computer-executable instructions for determining a correct offset between a first and a second set of measurement data, the computer-executable instructions directed to steps comprising: obtaining a first set of measurement data comprising measurements from a first element; obtaining a second set of measurement data comprising measurements from a second element causally related to the first element; identifying a range of measurements of the second measurement data corresponding to a state of the second element that is causally related to a measurable state of the first element; calculating a first value based on measurements from the first measurement data that correspond to the identified range of measurements of the second measurement data, given a first offset between the first measurement data and the second measurement data; repeating the calculating to calculate multiple values based on measurements from the first measurement data for multiple offsets incrementally different from the first offset; identifying a local extreme value of the first value and the multiple values within an identified range of offsets; and identifying, as the correct offset, a corresponding offset to the identified local extreme value.
