  • Patent number: 10284118
    Abstract: A two-axis angular pointing device includes a pivot bearing configured to support a payload. A first actuator is positioned to contact the payload at a first drive point. A second actuator is positioned to contact the payload at a second drive point. The first actuator is configured to generate a first movement of the payload in a direction substantially orthogonal to a plane defined by a center of the pivot bearing, the first drive point, and the second drive point to cause the payload to rotate around a first rotation axis. The second actuator is configured to generate a second movement of the payload at the second drive point in the direction substantially orthogonal to the plane to cause the payload to rotate around a second rotation axis. A method of making a two-axis angular pointing device is also disclosed.

  • Patent number: 10187037
    Abstract: A stick-slip stage device includes a carriage assembly configured to support a payload, the carriage assembly comprising at least three piezoelectric stick-slip actuators each having one or more contact points. At least two rails are positioned on opposing sides of the carriage assembly and configured to interact with one or more of the contact points to form a guideway for movement of the carriage assembly. A fixed structure connects the at least two rails and is configured to generate a friction force between the at least two rails and one or more of the contact points of the at least three piezoelectric stick-slip actuators. A method of making a stick-slip stage device is also disclosed.

  • Patent number: 9377619
    Abstract: A compact wide-angle optical beam steering device includes a first rotor with a first mirror surface and a second rotor with a second mirror surface. The rotors are arranged to rotate about an axis in response to frictionally coupled vibration motors. Drive circuits are coupled to the vibration motors and a control device is coupled to the drive circuits. The control device is configured to execute programmed instructions comprising generating and providing one or more driving signals to the vibration motors to drive the rotors to an angular position about the axes. A light source is positioned to emit a beam directed to the first mirror surface. The beam is reflected from the first mirror and contacts the second mirror. The second mirror is positioned to reflect the beam to exit the steering device at a pointing direction determined by the angular position of the mirrors.

  • Patent number: 9362851
    Abstract: A rotary motor and a method of making the same include a vibrating motor body which has two orthogonal first bending modes and is substantially enclosed within a housing. A shaft is frictionally coupled to the vibrating motor body and is arranged to rotate in at least one direction about a rotation axis in response to the vibrating motor body. The shaft is frictionally coupled the vibrating motor body by a force substantially perpendicular to the rotation axis. One or more bearings support the shaft, are connected to the housing, and define the axis of rotation of the shaft.

  • Patent number: 8797152
    Abstract: A haptic actuator apparatus and a method of making the same include an ultrasonically vibrating motor and its housing. The housing includes a guide structure coupled to the ultrasonically vibrating motor and at least one spring. The guide structure defines at least one path of motion of the ultrasonically vibrating motor. The at least one spring delimits the at least one path and generates human-detectable vibrations in response to an impact with the ultrasonically vibrating motor.

  • Patent number: 8466637
    Abstract: A method, computer readable medium, and apparatus for controlling a moveable element includes generating and providing with a control device one or more driving signals to one or more positioning actuators to move the moveable element towards a target position based on a target travel distance and a calibration value. The control device determines when a post-movement position of the moveable element is outside of a tolerance range of the target position. The control device recalibrates the calibration value when the post-movement position is determined to be outside of the tolerance range. The control device repeats the generating, the determining, and the recalibrating as open loop steps until the post-movement position is within the tolerance range or until a limit, if any, on attempts is reached.
