Description
Check membership in caller-annotated artifact windows without detecting or removing physiological events.
A research diary or bench measurement uses a defined observation window, clock, unit, and reference level. Missing timing, incomplete collection, and unverified measurements affect how a result can be interpreted. Record arithmetic and signal terms describe supplied data without establishing clinical status.
Check membership in caller-annotated artifact windows without detecting or removing physiological events.
When to use this tool
Use Uroflow Artifact Interval Token when you need a research-record or bench calculation with already supplied measurements, units, and observation boundaries.
How to use the tool and how it works
- Enter time, artifactStarts, artifactEnds, includeEnds. Keep parallel arrays aligned. Use the units and conventions below.
- Run the tool. Correct any format, range, or cross-field input error before interpreting the output.
- Read artifact, matchingIntervals. Inspect artifact before interpreting the associated values.
Require aligned artifactStarts and artifactEnds with every start<=end. Return zero-based matchingIntervals containing time, using inclusive starts and either inclusive ends or exclusive ends according to includeEnds, plus artifact when any match exists.1

}Limitations and assumptions
- Overlapping intervals can produce multiple matches. A zero-length interval matches only with inclusive ends; artifact labels are supplied rather than detected from a signal or clinically assessed.
- The field tables state structural bounds; the mechanics also specify cross-field constraints. Malformed inputs and unsupported domains cause errors. A successful false flag, empty branch value, or zero placeholder has the meaning stated above and is distinct from an input error.
- Numeric calculations use binary floating point unless exact decimal-integer arithmetic is explicitly stated. No hidden measurement tolerance or decimal rounding is added; nonfinite or out-of-contract results are rejected. Signed zero is exported as zero.
Alternative or Complementary methods
Use an appropriately validated measurement and analysis method for clinical interpretation. Verify diary completeness, clock conventions, and measurement units before combining these terms into a research summary.
