  • Free piston linear motor compressor and associated systems of operation
    Patent number: 11466678
    Abstract: A linear motor compressor including a compressor housing and a cylinder housing having a plurality of opposing compression chambers. A piston freely reciprocates within the cylinder housing using a linear electric motor. A piston position feedback control system provides adaptive current output as a function of position feedback and/or velocity feedback from the piston and/or the electric motor, to directly power and control the electric motor, wherein the piston reciprocates without assistance from a mechanical spring or other equivalent centering force.

  • Electromagnetic seismology vibrator systems and methods
    Patent number: 8699302
    Abstract: An electromagnetic system having a reaction mass with a field winding embedded therein, a base plate having an inner annular surface and an outer annular surface, and an armature winding coupled to at least a portion of the inner annular surface and at least a portion of the outer annular surface of an upper end portion of the base plate. In operation, directing an electric current in at least one of the field winding and the armature winding causes at least one of the base plate and the reaction mass to move relative to each other. The electromagnetic system can be used for seismic exploration and vibroseis applications, among other uses.
