CONTACTLESS OR NON-INVASIVE PHYSICAL PROPERTIES MEASUREMENT INSTRUMENT USING EDDY CURRENT-REDUCED HIGH Q RESONANT CIRCUIT PROBE

摘要

Eddy current measurement systems for a variety of bio-metric and other applications, where the target composition and/or other aspects cause relatively small eddy current losses, thus requiring a very high Q tuned circuit probe, and where ultra-miniature and ultra-low power products are required for convenient, non-invasive, and intrinsically safe wearable use

主权项

1. Non-invasive, high resolution eddy current measurement system, that
incorporates compact and very low power-consuming circuitry that permits convenient and unobtrusive portable and/or wearable products; is able to measure vital signs including but not limited to heart and respiration rate, and obtain other information about various bodily organs and fluids, such as to support electrocardiography, echocardiography, and glucometry; all without exceeding recognized current density and power dissipation safety thresholds.
