Magnetic induction dynamical devices for damping impacts and heating objects

Abstract

Proposed MID-devices comprise magnetic and electro-conductive means. High winds impacts or intermittent loads actuate a relative motion of the magnetic and electro-conductive means, inducing electric current within the latter, providing a damping of said impacts or loads, providing a heating usable for warming up homes, clothes (in gloves—by clapping hands), footwear (by a walking person), etc. Some embodiments include impact absorbing insertions (sometimes comprising spring-like materials, pneumatic chambers, or bladder-panels), disposed between or within the magnetic and electro-conductive means, and returning them toward their start position. Other embodiments deploy magnetic means facing each other with the same polarity, providing said returning. MID-devices combined with the pneumatic chambers or bladder-panels produce more efficient damping. Said electro-conductive means may include flexible conducting sheets, or coils with soft iron cores usable in damping, repulsing control, and power-generating modes. Said magnetic means may be concavely or convexly shaped stabilizing said relative motion.
