  • CENTRIFUGAL BRAKE FOR OVERSPEED PROTECTION
    Publication number: 20130313054
    Abstract: A centrifugally triggered brake mechanism is used to halt a rotating assembly. The brake mechanism includes a braking surface, a brake shoe, and a rotating centrifugal trigger. Upon attaining a selected rotational speed the trigger releases the brake pad to engage the drum. The mechanism may be useful for instance in providing backup overspeed protection for wind turbines.

  • DC MICROGRID FOR INTERCONNECTING DISTRIBUTED ELECTRICITY GENERATION, LOADS, AND STORAGE
    Publication number: 20120299386
    Abstract: A device includes an energy unit coupled to an energy device and adapted to couple a pair of split DC rails. A controller senses the voltage on the DC rails and regulates its output current response by means of an autonomous current response that creates the aggregate effect of controlling the rail voltage in cooperation with other units coupled to the DC rails. A system includes multiple such devices coupled to split DC rails.
