  • Apparatus and method for active shape control of a micro pick up array
    Patent number: 10814496
    Abstract: Structures and methods to actively control the shape of a micro pickup array (MPA) during micro device transfer are described. In an embodiment, a strain is applied to the MPA counteractive to strain arising during micro device transfer operations. For example, strain may be applied by a piezoelectric actuator element bonded to a back side of the base substrate to control a curvature of base substrate, and by extension the MPA.
    Type: Grant

  • Training mannikin
    Patent number: 5792032
    Abstract: A training system is formed by supporting a mannikin torso on a rigidly fixed base. The mannikin torso provides anatomically defined aiming references and may be attached to a frame which is supported by the base. The base allows the frame to be positioned either in a vertical or angled forward position to provide differing types of training. A harness is provided which is adapted to support the mannikin torso when it is detached from the frame and base. The harness has arm straps to allow a coach or trainer to move the mannikin torso to simulate more realistic sparring.
