  • Patent number: 10899045
    Abstract: A soft lithography template or stamp is made by casting a polydimethysiloxane (PDMS) or other suitable elastomeric precursor onto a master pattern. The master pattern may be formed utilizing known micro-fabrication techniques. The PDMS template includes an inverse copy of the micro-structures on the master pattern, and can be placed into a mold used to prepare a carbon-fiber reinforced polymer composite part or other polymer molding systems where a matrix material passes through a fluid state during the cure process. The liquid resin material flows into the structures on the surface of the PDMS template and hardens during the curing cycle. After the part is released from the mold, the PDMS template can be peeled from the surface of the part to reveal the free standing micro structures which are a replica of the master pattern.

  • Patent number: 10888487
    Abstract: A grasp assist system includes a glove having a glove palm and fingers, with the glove worn on a user's hand. A sensor measures flexion of the glove fingers, and thus a change of position and/or attitude of the fingers is determined. Finger saddles at least partially surround a phalange of a respective one of the user's fingers. The system uses one or more tendon actuators to pull on flexible tendons. Each tendon connects to a respective finger saddle. A controller is in communication with the actuators and sensor(s). The glove may use feedback from optional contact sensors to adjust tension, and may have a built-in restorative force. In executing a control method, the controller selectively applies tension to the tendons in response to finger flexion, via the tendon actuators, at a level sufficient for moving the user's fingers when the user executes a hand maneuver.

  • Patent number: 10724030
    Abstract: The present invention provides a system for delivering a time-varying stimulation field to a subject. In the system, a power source, a control component and a transmission component operate as a stimulation field generator to provide a predetermined time-varying stimulation field to up-regulate or down-regulate an expression level of human genes. The present invention also provides a wearable apparatus for delivering the time-varying magnetic field to mammalian cells associated with bone formation in a subject. The wearable apparatus contains the stimulation field generator in a housing. The resulted modification on gene regulation of these genes and mammalian cells promotes the retention, repair of and reduction of compromised mammalian cartilage, bone, and associated tissue.
