  • Positioning System
    Publication number: 20220324096
    Abstract: A system and method for a planar positioning system for an output member, the system having a pair of x-coordinate linear carriages and a pair of y-coordinate linear carriages. The system has a guide mechanism for the pair of x-coordinate linear carriages and the pair of y-coordinate linear carriages. The system has a plurality of movement and constraining cables extending from the pair of x-coordinate linear carriages and the pair of y-coordinate linear carriages to the output member for driving the output, wherein the pair of x-coordinate linear carriages and the output member move in sync in the x-direction and the pair of y-coordinate linear carriages and the output member move in sync in the y-direction. A restraint mechanism restrains the output member in an additional degree of freedom besides the x- and y-directions. The restraint can be a cable uptake and release device.

  • Multiple degree of freedom actuator and method
    Patent number: 8736148
    Abstract: Systems and methods for creating a multiple degree of freedom (DOF) actuated device having a single transducer source, wherein each DOF is individually actuated by a particular amplified response frequency and wherein simultaneous multiple DOF actuation is possible through superimposing multiple frequencies. Further included are several embodiments rectifying DOF(s) into a continuous output motion.
