- a plurality of magnets (40) wherein each of the plurality of magnets (40) has a north pole, wherein said plurality of magnets (40) are fixed on a front surface of said rotatable disk (42), wherein each of said plurality of magnets (40) has a flux Φ whereby each of said plurality of magnets (40) has a thickness through which each of said plurality of magnets is magnetized, wherein a plurality of south poles of said plurality of magnets (40) are fixed to said front surface of the rotatable disk (42) such that each said north pole of said plurality of magnets (40) is exposed;
- wherein said plurality of magnets (40) are each positioned on said rotatable disk (42), such that each of the plurality of magnets (40) has a longest axes that is radially aligned such that said plurality of magnets (40) are adjacent to and uniformly spaced about a perimeter of said rotatable disk (42);
- a plurality of variable reluctance, VR, sensors (44,45), wherein each has a pole piece (46), fixed to a contained magnet that is encircled by a coil of wire with an N number of turns, whereby said plurality of VR sensors (44,45) are mounted in a fixture such that said plurality of VR sensors (44,45) are proximate to and perpendicular to the rotatable disk (42) with said plurality of magnets (40), whereby the plurality of VR sensors (44,45) are spaced evenly around a circumference of said rotatable disk (42) such that each said pole piece (46) of the plurality of VR sensors (44,45) is exposed such that each said pole piece (46) of the plurality of VR sensors (44,45) overlaps a space inside and adjacent to the perimeter of said rotatable disk (42) with said plurality of magnets (40);
- whereby each said north pole of said plurality of magnets (40) is exposed, such that said rotatable disk (42) rotates in front of and in close proximity to each said pole piece (46) of said plurality of VR sensors (44,45);
- wherein said plurality of VR sensors (44,45) each produce a series of output voltage pulses (60);
- an electrical output device;
- an electronic circuit board, described as a diode board (70), which electrically connects each of the plurality of VR sensors' (44,45) said series of output voltage pulses (60), to each of a plurality of diode bridge rectifier circuits (72), wherein said diode board (70) also contains a two-stage series-parallel summing circuit, with a plurality of series summing circuits (74) electrically connected to a parallel summing circuit (76), a composite DC output voltage (78) and a DC-to-DC converter;
- wherein said plurality of diode bridge rectifier circuits (72) produce a plurality of outputs that are series summed in pairs in said plurality of series summing circuits (74) then electrically connected in parallel in said parallel summing circuit (76);
- wherein said summing circuit (76) produces said composite DC output voltage (78), whereby the composite DC output voltage (78) is electrically connected to said electrical output device, which on the diode board is said DC-to-DC converter;
- and
- a packaged system (20) which is connected to the user-worn, partially elastic, torso garment (21) wherein said package system (20) includes said ratchet gear system (30), and said gear train with said second cog gear (36) and said drive cog gear (38);
