  • Phacoemulsification Needle
    Publication number: 20200129330
    Abstract: A phacoemulsification needle can include a head with a lumen, a shaft with a lumen, and a hub with a lumen, wherein the lumen diameter increases from the head to the hub. In some embodiments, the head of the phacoemulsification needle can be tapered such that the proximal end of the head is wider than the distal end of the head. In some embodiments, the distal end of the head has a beveled tip. In some embodiments, the sides of the head can be tapered and hexagonal, square, or triangular in cross-section. In some embodiments, the phacoemulsification needle can decrease the amount of ultrasonic energy, aspiration rate, or vacuum needed during phacoemulsification of a cataract.

  • APPARATUS AND METHOD FOR CONTROLLING AXLE ROTATION DURING AXLE REPLACEMENT
    Publication number: 20190193690
    Abstract: Unlike axle replacement on vehicles, where the weight of the vehicle and air-assisted tools may be used, replacement of axle shafts in confined spaces (e.g. benchtop testing rigs) demand improved methods for controlling axle rotation during loosening and tightening of hub nuts. The present disclosure relates to an apparatus for controlling axle rotation during axle shaft replacement in confined spaces. The apparatus further includes a safety mechanism to prevent accidental team member injury caused by an independently rotating axle. Additionally, the disclosure describes a method of the apparatus for efficient loosening and tightening of hub nuts, reducing team member physical burden and expediting axle shaft replacement.

The HCC can further include a filter and an adaptive algorithm. The filter can receive IMU pressure and environment noise pressure as inputs. An error signal from the HCC output can also be supplied through a closed feedback loop that includes a Recursive Least Squares adaptive algorithm, which can further include a weighted, tapped delay line. The system can further include a remote data center for receiving the HCC output from the waterborne platform(s), which can be buoys, vessel or USV's.
