  • Publication number: 20210301796
    Abstract: An electrically controlled interfacial force generation device includes a first electrode, a second electrode, and a cell disposed between the first electrode and the second electrode. The cell includes a material that produces a mass in response to a bias voltage being applied across the first electrode and the second electrode. The device also includes a first wall at one end of the cell and extending between the first electrode and the second electrode. The device further includes an electrical power supply configured to provide a variable gradient voltage across the first electrode and the second electrode. A variable electric field gradient is produced and altered within the cell in response to the variable gradient voltage being altered. Altering the variable electric field gradient causes the mass to propagate across the cell and to impact the first wall transferring a force to the first wall.

  • Patent number: 10612626
    Abstract: A self-aligning wobble plate drive, including a stator gear, a wobble plate, and an output plate. The stator gear has a central stator axis and a plurality of stator teeth. The wobble plate has a wobble axis, a plurality of face teeth, and a plurality of wobble teeth, and is disposed such that the wobble axis is at a non-zero wobble angle relative to the stator axis. The output plate includes a plurality of output teeth and is substantially aligned with the stator axis. At least two of the pluralities of teeth are configured to engage with each other in a self-aligning manner such that as the wobble plate nutates around the stator gear, the wobble angle remains constant.

  • Patent number: 10574109
    Abstract: A wobble plate motor includes a wobble plate and a stator. The wobble plate is made of magnetically susceptible material and has a wobble axis. The stator includes a permanent magnet and a set of electromagnetic coils and has a stator axis. The wobble plate is configured to nutate around the stator with the wobble axis precessing around the stator axis. The wobble plate has a mobile point of closest approach with respect to the stator. The mobile point of closest approach moves around the stator axis as the wobble plate nutates. The permanent magnet and the set of electromagnetic coils are configured to create a magnetic field having a flux density between the stator and the wobble plate with a highest flux density at a mobile location ahead of the mobile point of closest approach in an angular direction around the stator axis as the wobble plate nutates.
