摘要： A method of forming an object from a material includes directing a first beam of light toward a first target location of the material to define a first portion of the object. The method also includes, after directing the first beam of light toward the first target location, determining an optical correction to be applied by an optical system. The optical correction is based on an atmospheric change in an atmospheric distortion region proximate the first target location due, at least in part, to interaction of the first beam of light and the material. The method further includes directing a second beam of light toward a second target location of the material to define a second portion of the object. The second beam of light is directed through at least a portion of the atmospheric distortion region while the optical correction is applied.

摘要： An elliptically interfacing gear assisted braking system may include an input shaft with a coupled input gear, a wobble plate, a rotor with a reaction gear, and an actuated brake mechanism, or brake. The input shaft may define an axis of rotation and the wobble plate may have a wobble axis disposed at a non-zero angle relative to the rotation axis. A set of face teeth disposed on one surface of the wobble plate may partially mesh with the input gear, and a set of wobble teeth on an opposite surface of the wobble plate may partially mesh with the reaction gear. Rotation of the input shaft may thereby cause rotation of the wobble plate and rotor. The brake may mate with the rotor and when actuated, slow the rotor with respect to the input shaft. Rolling contact forces between the surfaces of the wobble teeth and reaction teeth may then induce nutation in the wobble plate, thereby dissipating rotational energy.

摘要： 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.

摘要： An elliptically interfacing gearbox system may include an input plate having a rotation axis and a plurality of input teeth. The gearbox system may include a wobble plate having a wobble axis disposed at a non-zero angle relative to the rotation axis, a rear face, and a plurality of face teeth disposed on the rear face. The wobble plate may further include a first plurality of wobble teeth disposed in a first plane perpendicular to the wobble axis and a second plurality of wobble teeth disposed in a second plane perpendicular to the wobble axis. The second plane may be spaced from the first plane along the wobble axis. The gearbox system may include a stator gear having a plurality of stator teeth and an output plate having an output axis substantially aligned with the rotation axis and a plurality of output teeth. The plurality of input teeth may be configured to engage with the plurality of face teeth, the first plurality of wobble teeth may be configured to engage with the plurality of stator teeth, and the second plurality of wobble teeth may be configured to engage with the plurality of output teeth as the wobble plate nutates around the stator gear.

摘要： A method and apparatus for operating a reluctance motor. The apparatus comprises a stator and a plate. The stator includes a plurality of electromagnetic coils having an overlapped configuration. Applying multi-phase current to the plurality of electromagnetic coils generates a magnetic field. The plate forms a virtual pole when a portion of the plate contacts the stator in response to the magnetic field. Rotating the magnetic field about a center axis through the stator rotates the virtual pole about the center axis.

摘要： 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.
