    "goal": "To determine energetic and physical conditions, radiation sensitivity, and energetic anomalies for biodetection and dowsing.",
    "problem_addressed": "Existing dowsing and biodetection instruments are unsatisfactory, lacking sensitivity, reproducibility, and resistance to magnetic interference.",
    "concept_summary": "A spring pendulum consisting of a metal tube, an elastic wire spring, and a non-magnetic mass ball. The spring slides within a protective sleeve and is clamped by a rubber or plastic bearing, providing high sensitivity to magnetic/electric radiation while being insensitive to local magnetic fields. The device is used together with a special protractor for qualitative and quantitative measurements of energetic fields.",
    "detailed_description": "The invention comprises a cross-shaped radiesthesia rod (RO123463) and a spring pendulum test device (DE4116941). The pendulum includes a handle and a metallic protective tube (non-magnetic stainless steel, Cr/Ni alloy), an extractable elastic wire spring (tempered Cr/Ni steel), and a mass element (steel ball). The spring is held radially by an elastic clamp made of natural rubber, nylon, or polyamide (PA6). Various embodiments describe different tube dimensions, spring diameters, and bearing materials (brass stop plate, Viton rubber). The device is designed for small size, maneuverability, long life, and high sensitivity to radiation effects, with claimed insensitivity to local magnetic fields.",
