Energy transfer from a drum to a displacement element

An energy transfer apparatus, comprising:

• an electromechanical servo gauge having a motor;
• a displacer connected to the electromechanical servo gauge by a wire, the displacer having a displacer body and the displacer including a displacer element connected to a moveable element, the wire attached to the displacer, wherein the displacer hangs from the wire, the wire comprising a measuring wire, wherein energy is transferred from the motor of the electromechanical servo gauge to the displacer using the motor and the wire combined with mechanical drag;
• and
• a spring located between the wire and a mass inside the displacer, wherein a lifting and a lowering of the displacer body generates an oscillation usable to generate the energy.

An energy transfer apparatus, comprising:

• an electromechanical gauge having a motor;
• a displacer connected to the electromechanical gauge by a wire, the displacer including a moving element that introduces mechanical drag when the displacer is moved through a liquid by the motor, wherein energy is transferred from the motor of the electromechanical gauge to the displacer using the motor and the wire combined with the mechanical drag;
• and
• wherein the motor comprises a servo motor coupled to a drum by a drive shaft supported by ball bearings positioned between the drive shaft and a housing, and wherein the drum is supported at a drum shaft by bearings configured to carry the drum, and wherein the drum includes outer magnets magnetically coupled to inner magnets carried by the drive shaft to transfer torque to a processor side of the electromechanical gauge;
• and a spring located between the wire and a mass inside the displacer, the displacer comprising a displacer body, wherein a lifting and lowering of the displacer generates an oscillation of the displacer body, wherein the oscillation is usable to generate the energy.
