  • Patent number: 10625424
    Abstract: A machine that is capable of assembling a copy of itself from a feedstock of parts is described. The machine operates on a lattice or grid on which it is able to move and from which it receives power and control signals. The machine (assembler) is composed of modules that each perform some functionality. In the simplest case, only three module types are needed: a linear step module, a gripper, and an anchor. The linear step module is capable of moving from one lattice location to the next, the gripper module is capable of gripping other modules, and the anchor module is capable of attaching the machine to the grid. With these three primitives it is possible for this simple machine to move on the grid using inchworm-like motions, pick up other modules, and assemble a copy of itself.

  • Patent number: 10584067
    Abstract: Disclosed is a focused ultrasonic piezoelectric actuator having a novel type of piezoelectric device for focusing ultrasonic waves. The focused ultrasonic piezoelectric actuator includes a dome-shaped piezoelectric body for focusing ultrasonic waves and a rim configured to facilitate focusing of ultrasonic waves of the body and injection of the dome-shaped piezoelectric body during a powder injection molding process, remove warpage of the dome-shaped body during a sintering process, and reinforce focusing intensity of the ultrasonic waves. The rim is integrally formed with the body. Accordingly, in the focused ultrasonic piezoelectric actuator, a dome-shaped focused ultrasonic piezoelectric actuator for focusing ultrasonic waves using a thickness vibration mode at a MHz frequency band is easily manufactured by a powder injection molding method, and thus an ultrasonic focusing effect is maximized.
