Patents by Inventor Patrick Ostlund

Patrick Ostlund has filed for patents to protect the following inventions. This listing includes patent applications that are pending as well as patents that have already been granted by the United States Patent and Trademark Office (USPTO).

  • Free-mass and interface configurations of hammering mechanisms
    Patent number: 8960325
    Abstract: The design of the free-mass in an ultrasonic driller/corer (USDC) has been refined in order to improve the performance and operational reliability of the system. In one embodiment, the improvements in performance and operational reliability include decreasing the impact surface area of the free-mass to increase the transfer of impact energy from the piezoelectric transducer and reductions in the likelihood that the system will jam.
    Type: Grant
    Filed: October 27, 2011
    Date of Patent: February 24, 2015
    Assignee: California Institute of Technology
    Inventors: Xiaoqi Bao, Stewart Sherrit, Mircea Badescu, Yoseph Bar-Cohen, Steve Askins, Patrick Ostlund
