Integrates the supplied current over time by the trapezoidal rule, so the result is only as good as the sampling interval; gaps longer than the stated max_gap_seconds are excluded and reported. Sign convention: positive current is charging, negative is discharging. Internal resistance is estimated from the largest current step in the series and is a rough figure, not a measurement under defined conditions.

Grade any physical Pokémon, Magic: The Gathering, Yu-Gi-Oh, or Digimon trading card using a 3-stage AI pipeline: (1) Qwen Vision LLM analyzes corners, edges, and surface defects, (2) OpenCV measures exact centering ratios programmatically, (3) BGS professional capping algorithm adjusts the final grade. Returns PSA/Beckett-calibrated subgrades and an overall condition score. Accepts card image URLs or base64.

Conductor mass is calculated from nominal cross-section, core count and length against the material density; for a nominal cross-section this is exact and independent of stranding. Total cable mass and the copper share are returned as a range derived from published manufacturer weight tables per cross-section band, not as a type-test value. Insulation, filler and armour are not modelled individually.
