  • Patent number: 9188205
    Abstract: A moon gear assembly is provided that includes a moon arm assembly having a driving moon gear. A pivot pin is connected to the moon arm assembly, and an adjustment arm is connected to the moon arm assembly. The moon arm assembly may also include a body that defines a chamber, a worm gear disposed in the chamber and arranged to interact with the driving moon gear, and a motor disposed in the chamber and couple to the worm gear.

  • Publication number: 20140127813
    Abstract: Systems, devices, and methods for delivering a biological material into an organelle of a cell are provided. In one aspect, for example, a method for introducing biological material into an organelle of a cell can include bringing into proximity outside of a cell a lance and a preselected biological material, charging the lance with a polarity and a charge sufficient to electrically associate the preselected biological material with a tip portion of the lance, and penetrating an outer portion of the cell with the lance and directing and inserting the lance into the cell but outside of the organelle. The method can further include discharging the lance to release at least a portion of the biological material, charging the lance with an opposite polarity and charge sufficient to electrophoretically drive at least a portion of the biological material into the organelle, and withdrawing the lance from the cell.

  • Publication number: 20110059821
    Abstract: Transmission systems, assemblies, and components are described. In particular, aspects of the present disclosure relate to an infinitely variable transmission that maintains constant tooth engagement during changes in gear ratio. In one aspect, a transmission includes an axially movable sheave coupled to a chain. The sheave rotates around a drive axis. At least partially within the sheave is a set of moon gears. The moon gears orbit around the drive axis and are rotatable around respective internal axis. As the sheave moves axially, the chain and the set of moon gears move radially to define different gear ratios, with the gear ratios being changeable in infinitely small increments. A synchronization system moves the set of moon gears radially to correspond to the axial position of the sheave. A correction system optionally controls rotation of the moon gears to rotate teeth of the moon gears into alignment with the chain.
